Сет под пиво - 990 рублей. Первым курсом в ожидании остальных блюд заказали "Сет под пиво". Выбор был простой, в данном сете есть почти все предлагаемые холодные закуски. Давайте по порядку. На тарелке покупной чилли соус, претензий не имею, но не совсем понимаю к чему он, чипсы не мокнешь, жареный сыр с ним приобретает странный вкус, а кальмара просто неудобно окунать. Картофельные чипсы - чистый кайф, отлично по соли, домашние и хрустящие. Мясные чипсы тоже достойные, под пенное прекрасно идут, неплохо жуются. Но не совсем понял зачем жарить сыр косичку, я бы лучше съел в натуральном виде, а так только вкус фритюра.
Testosterone RIA and LH using microparticle enzyme immunoassay [MEIA] concentrations during minipuberty correlate negatively with body weight and body mass index until the age of 6 years. The level of estradiol RIA during minipuberty correlates positively with the skin-fold thickness during the first 6 years. No such influence has been observed in girls [ 13 ]. In studies on female rats, it has been demonstrated that postnatally administered estradiol and testosterone has a programming effect on the development of adipose tissue later in life [ 43, 44 ].
Growth Data on the influence of minipuberty on growth velocity are conflicting. Another study, based on serial serum testosterone measurement in 35 babies, found no correlation between testosterone concentration RIA during minipuberty and growth velocity at any time point during the first 6 years [ 13 ]. Whether this difference is due to the different sampling materials urinary vs. In a retrospective study on infants with multiple pituitary hormone deficiency including growth hormone deficiency , growth under early growth hormone substitution starting in the first year of life was improved in those not suffering from hypogonadism but not in those with hypogonadism, and hence not having a minipuberty , suggesting a potential impact of minipuberty on growth during the first year of life [ 46 ].
Minipuberty and Its Influence on Cognitive Development The hormonal rise during minipuberty affects not only somatic development, but also cognitive development. Brain plasticity remains high during minipuberty and the brain continues to develop rapidly throughout the early postnatal period [ 47 ], making a possible influence of minipuberty on brain development conceivable. It is a well-known fact that, on average, girls tend to acquire linguistic skills earlier and with a greater level of complexity than boys [ 48 ]. Several studies based on 1 cohort of patients showed associations of gonadotrophic and sex hormone values during minipuberty with speech development.
In 4-week-old babies, recording event-related brain potentials ERP revealed a clear phonological discrimination effect with a bilateral distribution in girls. In boys, the discrimination effect was correlated with the testosterone value RIA at this age. Boys with a high level of testosterone showed no discrimination effect, but those with a low testosterone level showed a left lateralized discrimination effect [ 49 ]. The level of estradiol RIA at the age of 4 weeks has been positively correlated with the melody complexity index MCI at the age of 4 and 8 weeks.
Interestingly, testosterone serum concentration RIA at the age of 20 weeks was negatively correlated with their babbling capacity [ 51 ]. These data are in line with the findings of a study based on salivary testosterone measurements EIA. Salivary testosterone at the age of 1—3 months was negatively correlated to the size of the parent-reported expressive vocabulary in boys and in girls, and mediated the sex difference in the expressive vocabulary at 18—30 months of age [ 53 ]. These studies all suggest that sex hormone concentrations during minipuberty may indeed influence language development up to the age of 5 years.
The findings are supported by animal studies which show that postnatally administered sex hormones influence brain development and behavior later in life [ 54, 55 ]. Minipuberty and Its Influence on Behavior There are several studies examining the influence of minipuberty on behavior. A study based on salivary testosterone measurement EIA in infants males and females aged 3—4. Based on this study, it has been hypothesized that testosterone levels during minipuberty could influence emotional regulation in male infants [ 56 ].
A further study by this group showed that, in male infants, higher salivary androgen levels predicted a stronger preference for male-typical stimuli at the age of 3—4 months [ 57 ]. In this study cohort, no significant differences between the sexes in salivary testosterone levels EIA , which are extremely sex-distinct during this time period in the serum RIA [ 13 ], were observed. This might have been due to the sampling material that was chosen or the delayed sampling time after the age of 3 months. Based on the same cohort, a correlation of the obtained salivary testosterone values EIA at the age of 3—4.
It was observed that there was no influence of salivary testosterone levels during minipuberty on gender-linked play behavior [ 58 ] or eye-contact time [ 59 ] in young children of either sex. This has been supported by a study which used penile growth during the first 3 months as an indirect marker for testosterone concentrations during minipuberty. This study revealed a significant positive correlation between penile growth during the first 3 months and masculine behavior, and a negative correlation with feminine behavior at the age of 3—4 years assessed using the Preschool Activities Inventory [ 61 ]. In studies with Rhesus monkeys, the manipulation of the postnatal testosterone surge significantly affected penile growth and development but did not affect the expression of sex differences in play and sexual behavior [ 62, 63 ].

This was confirmed by a study based on serial urinary measurements using time-resolved immunofluorometric assay [TR-IFMA] [ 21 ]. Based on this evidence, it seems that the onset of minipuberty in preterm babies is similar to that in full-term babies, but that the HPG axis activation in the former is increased and prolonged, resulting in higher sex steroid concentrations than in the latter. It is still not clear by which mechanism the activation of the HPG axis is silenced after a few months. Minipuberty is a window of opportunity to examine the HPG axis. A serum LH and FSH measurement in this period may help to diagnose infants with hypogonadotropic hypogonadism. Later in infancy, the HPG axis is physiologically quiescent, so diagnosing hypogonadotropic hypogonadism at this early stage can help to induce puberty at the appropriate physiological age. Since the hormonal rise is gender-specific during minipuberty, hormone analyses can help to classify biological sex in infants with a suspected disorder of sexual development DSD.
Minipuberty and Its Influence on Genital Organ Development and Fertility In general, the transient rise in testosterone in boys or estradiol in girls is not followed by clinically visible physical changes. Ultrasound evaluation of testicular size may document a transient not detectable by palpation increase in testicular volume during minipuberty [ 24 ]. In rare cases, the transient rise of sex hormones can result in transient clinical visible pubertal signs in otherwise healthy infants: vaginal bleeding in girls [ 25 ] or palpable testicular growth with the development of pubic hair in boys [ 26, 27 ]. Regarding the persisting effects of minipuberty, the hormonal surge is of importance for penile growth and testicular development in boys. Testosterone levels RIA in minipuberty correlate positively with penile growth and penile growth velocity [ 28 ]. In male babies suffering from hypogonadotropic hypogonadism, treatment with subcutaneously administered gonadotropins postnatally can provide normal penile growth and is an effective therapy for micropenis in infancy [ 29 ], but data about the outcome of long-term treatment are missing. Only 1 study has evaluated the long-term outcome of administering subcutaneous FSH in combination with intramuscular testosterone in the first months of life in 3 patients [ 30 ]. Penile length was not commented on in this study. More studies are warranted to evaluate the long-term efficacy of this treatment.
During minipuberty, an increase in the number of Sertoli cells [ 31 ] and germ cells [ 32 ] is observed in the testicles. As Sertoli cells do not express an androgen receptor during infancy, the rise in testosterone during minipuberty does not induce spermatogenesis [ 33 ]. However, the postnatal transient activation of the HPG axis seems to play an important role in fertility in boys. Several studies in cryptorchidic boys showed an insufficient maturation of gonadocytes into type A-dark spermatocytes [ 34 ]. This supports the hypothesis that cryptorchidism is not the cause of infertility, but rather a sign of a disturbed HPG axis. According to this hypothesis, the abnormal HPG axis and ensuing defective minipuberty influence future infertility. The current European guideline for urology from 2016 therefore suggests offering treatment with a GnRH analog to boys with bilateral undescended testes to improve their fertility outcome [ 37 ]. On the other hand, there are studies showing a higher rate of germ cell apoptosis in adults after prepubertal human chorionic gonadotropin hCG treatment for cryptorchidism [ 38 ]. As there is a lack of evidence of long-term efficacy to improve fertility by hormonal treatment, the current guideline of the American Urology Association from 2014 [ 37 ] and the consensus of the Nordic countries from 2007 [ 39 ] do not recommend hormone therapy.
Further studies evaluating adult fertility and the potential side effects after preoperative GnRH therapy during the first year of life are therefore urgently required. In animal models, Li et al. In girls, there is less evidence to support the influence of minipuberty on fertility and development of the genital organs, buta positive correlation of the mammary gland diameter and estradiol RIA at the age of 3 months has been described [ 42 ]. There are no data available concerning longer-lasting effects of estradiol concentration during minipuberty on fertility or breast and uterine development in adult women. Minipuberty and Its Influence on Somatic Development There are studies evaluating the influence of minipuberty on body composition and growth. Body Composition Hormone concentrations during minipuberty influence the somatic development during the first 6 years in boys. Testosterone RIA and LH using microparticle enzyme immunoassay [MEIA] concentrations during minipuberty correlate negatively with body weight and body mass index until the age of 6 years.

К слову, вечер можно было продолжить и здесь, после 22. Ближе к этому времени музыка играет громче, людей всё больше и атмосфера становится живой. Посадочных мест много, как мне показалось, все они удобные и просторные. Отличие только в том, у окна оно или в глуби зала. Туалет чистенький, только тёмноватый. Вот правда, не к чему было придраться. Поэтому у меня достаточно болшой багаж заведений где я побывал, и мне есть с чем сравнить, как в Петербурге, так и по России. Я побывал в Puberty 12. Нас встретила молоденькая администратор, оглядела нас таким взгоядом, будто мы только что при ней вылезли из подворотни, я уж побоялся, что прогонит, но все таки снисходительно провела к столику. Огромный зал заведения был почти пуст - клиентов не было, но официанты бегали взад вперед с очень занятыми лицами, и не особо обращали на нас внимание, ну и в целом вели себя довольно безучастно и не приветливо. Стол вытирали и стакан убирали исправно, но вот общение - не их сильная сторона. Поймите правильно: когда я захожу в столовку за 200 руб, я не ожидаю от этого ничего кроме какой-нибудь еды, но когда речь о таком заведении, как puberty, с ценами как в неплохом ресторане, и с соответствующей обстановкой, я хочу почувствовать себя комфортно. Кстати о еде: не знаю на чем специализируется кухня заведения потому что в меню есть «от батона до пистона» , но моя пицца под названием puberty оказалась самая обычная и кроме сытости ничего не вызвала. Пиво здесь вкусное и свежее! Но поверьте, в Питере есть еще места с таким же отличным пивом. И кстати о пиве: я коллекционирую фирменные печати пивоварен в специальном пивном паспорте, привезенном специально из Чехии. В паберти как и во многих пивоварнях в России, нету фирменной печати пивоварни. Но в других местах везде предлагали какие то альтернативные варианты: фирменные наклейки, ооошные или ипшные печати, и т. Я считаю, мой конкретный пример может проиллюстрировать, холодное и беспонтовое отношение к клиенту. В общем, если собрались сюда, знайте заранее: здесь вас не любят. По совокупности факторов, учитывая кач-во обслуживания, вкус, цену , моя оценка - кол. Накидываю один балл за пиво. Пиво на любителя. Парковки считайте что нет. Пользовались этой услугой какое-то время, потом отказались: порции крошечные, ценник заряженный, еда вся в майонезе да и набор блюд на бизнес может оказаться таким, что даже непривередливой мне есть нечего.. Возможно, вечерами лучше, но днём точно нет. Варят пиво в чешском стиле. Правда, оборудование австрийское и чеш, выучив местного пивовара, уже уехал, но получается очень вкусно. Я сел за стойку, познакомился с бар-шефом Дэном. Он мне устроил дегустацию бесплатную а позже еще и сводил - показал варочный порядок и дробильные танки.

Fetal testosterone also influences sexually dimorphic brain development [ 8 ]. In the female fetus, the rise of gonadotropins in utero is observed as well, but the estradiol production is predominantly of placental origin.
The estradiol peak occurs in the third trimester of pregnancy Fig. Corbier et al. Minipuberty The second endocrine puberty takes places at the age of 1—6 months. This is the second transient activation of the HPG axis. Minipuberty was first described by Forest et al. Since then, the elevation of hormones at minipuberty has been well characterized, and an increasing number of studies have been published in an attempt to understand this phenomenon. Here, we review the current research on minipuberty, focusing on its influence upon: 1 the development of genital organs and fertility, 2 somatic development, 3 cognitive development,and 4 behavior.
Hormonal Changes during Minipuberty The rise of gonadotropins LH and FSH observed in minipuberty stimulates testosterone production in the testicles in boys and estradiol production in the ovaries in girls Fig. After birth, in the absence of placental steroids suppressing the HPG axis, the HPG axis becomes progressively active again. Gonadotropin levels RIA rise approximately 1 week postnatally [ 11 ]. LH levels RIA are higher in boys than in girls, peaking between the 2nd and 10th week of life and declining thereafter to prepubertal levels by the age of 4—6 months [ 11-13 ]. FSH levels RIA are higher in girls than in boys during minipuberty [ 11-13 ] and stay elevated until the age of 3—4 years in girls, but not in boys in whom a decline to prepubertal values occurs by the age of 6 months [ 12 ]. In boys, LH stimulates testosterone production, so the level of testosterone increases RIA , peaking in the 2nd—3rd month of life [ 13, 14 ]. During this time, the testosterone values may reach those of fertile adult men [ 13, 14 ].
Androgen production seems to occur rather via the backdoor pathway than the classic pathway [ 15 ]. Before the age of 6 months, testosterone levels will be again in the prepubertal range. There is a wide interindividual variation in testosterone values [ 13 ]. A study based on salivary testosterone measurements concluded that, in contrast to the strong genetic contribution observed in classical puberty, minipuberty seems to be strongly influenced by environmental factors. It has been found that genetic variants influencing salivary testosterone levels detected by enzyme immunoassay [EIA] in males are regulators of reproductive function and cholesterol; in females, genes related to estrogen signaling are more important [ 16 ]. Further studies are needed to understand the factors contributing to the interindividual variations in the transient sex hormone surge during minipuberty. In some animal species, a transient activation of the HPG axis in males is observed.
A testosterone surge RIA is also observed in neonatal male rats, male mice, and male foals [ 9 ]. Estradiol RIA rises more in girls than in boys [ 13, 14 ], with a level of Tanner stage 4 being normal in girls [ 18 ]. The difference between the sexes in the level of estradiol is, however, less significant than the level of testosterone [ 13, 14 ]. Data on hormonal changes in minipuberty in preterm babies are scarce. Reference data based on serum measurements in 82 preterm babies for LH and FSH measured by immunochemiluminometric assay [ICMA] showed higher values for gonadotropins in preterm infants than in full-term infants, and higher LH and FSH values in preterm girls than in preterm boys [ 20 ]. This was confirmed by a study based on serial urinary measurements using time-resolved immunofluorometric assay [TR-IFMA] [ 21 ]. Based on this evidence, it seems that the onset of minipuberty in preterm babies is similar to that in full-term babies, but that the HPG axis activation in the former is increased and prolonged, resulting in higher sex steroid concentrations than in the latter.
It is still not clear by which mechanism the activation of the HPG axis is silenced after a few months. Minipuberty is a window of opportunity to examine the HPG axis.
Мясные чипсы тоже достойные, под пенное прекрасно идут, неплохо жуются. Но не совсем понял зачем жарить сыр косичку, я бы лучше съел в натуральном виде, а так только вкус фритюра. Кальмар покупной, я все сказал.

However, they have based their conclusions on a comparison of data from 1999 with data from 1969. In the earlier example, the sample population was based on a small sample of white females 200, from Britain. Kallmann syndrome is also associated with a lack of sense of smell anosmia. Kallmann syndrome and other forms of HH affect both men and women. It is caused by a failure in HPG axis at puberty which results in low or zero gonadotropin LH and FSH levels with the subsequent result of a failure to commence or complete puberty, secondary hypogonadism and infertility. Please discuss at the talk page and do not remove this message until the contradictions are resolved.
April 2021 The average age at which the onset of puberty occurs has dropped significantly since the 1840s. In Norway , females born in 1840 had their menarche at an average age of 17 years. In France, the average in 1840 was 15. In Japan , the decline happened later and was then more rapid: from 1945 to 1975 in Japan there was a drop of 11 months per decade. A 2006 study in Denmark found that puberty, as evidenced by breast development, started at an average age of 9 years and 10 months, a year earlier than when a similar study was done in 1991.
Scientists believe the phenomenon could be linked to obesity or exposure to chemicals in the food chain, and is putting females at greater long-term risk of breast cancer. The specific genes affecting timing are not yet known. One of the first observed environmental effects is that puberty occurs later in children raised at higher altitudes. The most important of the environmental influences is clearly nutrition, but a number of others have been identified, all which affect timing of female puberty and menarche more clearly than male puberty. Hormones and steroids There is theoretical concern, and animal evidence, that environmental hormones and chemicals may affect aspects of prenatal or postnatal sexual development in humans.
Sex steroids are sometimes used in cattle farming but have been banned in chicken meat production for 40 years. Although agricultural laws regulate use to minimize accidental human consumption, the rules are largely self-enforced in the United States. Significant exposure of a child to hormones or other substances that activate estrogen or androgen receptors could produce some or all of the changes of puberty. Harder to detect as an influence on puberty are the more diffusely distributed environmental chemicals like PCBs polychlorinated biphenyl , which can bind and trigger estrogen receptors. More obvious degrees of partial puberty from direct exposure of young children to small but significant amounts of pharmaceutical sex steroids from exposure at home may be detected during medical evaluation for precocious puberty , but mild effects and the other potential exposures outlined above would not.
Bisphenol A BPA is a chemical used to make plastics, and is frequently used to make baby bottles, water bottles, sports equipment, medical devices, and as a coating in food and beverage cans. BPA mimics and interferes with the action of estrogen—an important reproduction and development regulator. The highest estimated daily intakes of BPA occur in infants and children. Many plastic baby bottles contain BPA, and BPA is more likely to leach out of plastic when its temperature is increased, as when one warms a baby bottle or warms up food in the microwave. Surplus calories beyond growth and activity requirements are reflected in the amount of body fat , which signals to the brain the availability of resources for initiation of puberty and fertility.
Much evidence suggests that for most of the last few centuries, nutritional differences accounted for majority of variation of pubertal timing in different populations, and even among social classes in the same population. Recent worldwide increased consumption of animal protein, other changes in nutrition, and increases in childhood obesity have resulted in falling ages of puberty, mainly in those populations with the higher previous ages. In many populations the amount of variation attributable to nutrition is shrinking. Although available dietary energy simple calories is the most important dietary influence on timing of puberty, quality of the diet plays a role as well. Lower protein intakes and higher dietary fiber intakes, as occur with typical vegetarian diets , are associated with later onset and slower progression of female puberty.
Obesity influence and exercise Scientific researchers have linked early obesity with an earlier onset of puberty in females. They have cited obesity as a cause of breast development before nine years and menarche before twelve years. A high level of exercise, whether for athletic or body image purposes, or for daily subsistence, reduces energy calories available for reproduction and slows puberty. The exercise effect is often amplified by a lower body fat mass and cholesterol. Physical and mental illness Chronic diseases can delay puberty in both males and females.
Those that involve chronic inflammation or interfere with nutrition have the strongest effect. In the western world, inflammatory bowel disease and tuberculosis have been notorious for such an effect in the last century, while in areas of the underdeveloped world, chronic parasite infections are widespread. Mental illnesses occur in puberty. The brain undergoes significant development by hormones which can contribute to mood disorders such as major depressive disorder , bipolar disorder , dysthymia and schizophrenia. In comparison with the effects of genetics, nutrition, and general health, social influences are small, shifting timing by a few months rather than years.
Mechanisms of these social effects are unknown, though a variety of physiological processes, including pheromones , have been suggested based on animal research. Most of the studies have reported that menarche may occur a few months earlier in females in high-stress households, whose fathers are absent during their early childhood, who have a stepfather in the home, who are subjected to prolonged sexual abuse in childhood, or who are adopted from a developing country at a young age. Conversely, menarche may be slightly later when a female grows up in a large family with a biological father present. More extreme degrees of environmental stress, such as wartime refugee status with threat to physical survival, have been found to be associated with delay of maturation, an effect that may be compounded by dietary inadequacy. Most of these reported social effects are small and our understanding is incomplete.
Most of these "effects" are statistical associations revealed by epidemiologic surveys. Statistical associations are not necessarily causal, and a variety of covariables and alternative explanations can be imagined. Effects of such small size can never be confirmed or refuted for any individual child. Furthermore, interpretations of the data are politically controversial because of the ease with which this type of research can be used for political advocacy. Accusations of bias based on political agenda sometimes accompany scientific criticism.

More obvious degrees of partial puberty from direct exposure of young children to small but significant amounts of pharmaceutical sex steroids from exposure at home may be detected during medical evaluation for precocious puberty , but mild effects and the other potential exposures outlined above would not. Bisphenol A BPA is a chemical used to make plastics, and is frequently used to make baby bottles, water bottles, sports equipment, medical devices, and as a coating in food and beverage cans. BPA mimics and interferes with the action of estrogen—an important reproduction and development regulator. The highest estimated daily intakes of BPA occur in infants and children. Many plastic baby bottles contain BPA, and BPA is more likely to leach out of plastic when its temperature is increased, as when one warms a baby bottle or warms up food in the microwave.
Surplus calories beyond growth and activity requirements are reflected in the amount of body fat , which signals to the brain the availability of resources for initiation of puberty and fertility. Much evidence suggests that for most of the last few centuries, nutritional differences accounted for majority of variation of pubertal timing in different populations, and even among social classes in the same population. Recent worldwide increased consumption of animal protein, other changes in nutrition, and increases in childhood obesity have resulted in falling ages of puberty, mainly in those populations with the higher previous ages. In many populations the amount of variation attributable to nutrition is shrinking. Although available dietary energy simple calories is the most important dietary influence on timing of puberty, quality of the diet plays a role as well. Lower protein intakes and higher dietary fiber intakes, as occur with typical vegetarian diets , are associated with later onset and slower progression of female puberty. Obesity influence and exercise Scientific researchers have linked early obesity with an earlier onset of puberty in females. They have cited obesity as a cause of breast development before nine years and menarche before twelve years.
A high level of exercise, whether for athletic or body image purposes, or for daily subsistence, reduces energy calories available for reproduction and slows puberty. The exercise effect is often amplified by a lower body fat mass and cholesterol. Physical and mental illness Chronic diseases can delay puberty in both males and females. Those that involve chronic inflammation or interfere with nutrition have the strongest effect. In the western world, inflammatory bowel disease and tuberculosis have been notorious for such an effect in the last century, while in areas of the underdeveloped world, chronic parasite infections are widespread. Mental illnesses occur in puberty. The brain undergoes significant development by hormones which can contribute to mood disorders such as major depressive disorder , bipolar disorder , dysthymia and schizophrenia. In comparison with the effects of genetics, nutrition, and general health, social influences are small, shifting timing by a few months rather than years.
Mechanisms of these social effects are unknown, though a variety of physiological processes, including pheromones , have been suggested based on animal research. Most of the studies have reported that menarche may occur a few months earlier in females in high-stress households, whose fathers are absent during their early childhood, who have a stepfather in the home, who are subjected to prolonged sexual abuse in childhood, or who are adopted from a developing country at a young age. Conversely, menarche may be slightly later when a female grows up in a large family with a biological father present. More extreme degrees of environmental stress, such as wartime refugee status with threat to physical survival, have been found to be associated with delay of maturation, an effect that may be compounded by dietary inadequacy. Most of these reported social effects are small and our understanding is incomplete. Most of these "effects" are statistical associations revealed by epidemiologic surveys. Statistical associations are not necessarily causal, and a variety of covariables and alternative explanations can be imagined. Effects of such small size can never be confirmed or refuted for any individual child.
Furthermore, interpretations of the data are politically controversial because of the ease with which this type of research can be used for political advocacy. Accusations of bias based on political agenda sometimes accompany scientific criticism. Another limitation of the social research is that nearly all of it has concerned females, partly because female puberty requires greater physiologic resources and partly because it involves a unique event menarche that makes survey research into female puberty much simpler than male. More detail is provided in the menarche article. Variations of sequence The sequence of events of pubertal development can occasionally vary. Rarely, menarche can occur before other signs of puberty in a few females. These variations deserve medical evaluation because they can occasionally signal a disease. Neurohormonal process The endocrine reproductive system consists of the hypothalamus , the pituitary , the gonads , and the adrenal glands , with input and regulation from many other body systems.
True puberty is often termed "central puberty" because it begins as a process of the central nervous system. The ovaries or testes respond to the rising amounts of LH and FSH by growing and beginning to produce estradiol and testosterone. Rising levels of estradiol and testosterone produce the body changes of female and male puberty. The onset of this neurohormonal process may precede the first visible body changes by 1—2 years. Components of the endocrine reproductive system The arcuate nucleus of the hypothalamus is the driver of the reproductive system. It has neurons which generate and release pulses of GnRH into the portal venous system of the pituitary gland. The arcuate nucleus is affected and controlled by neuronal input from other areas of the brain and hormonal input from the gonads , adipose tissue and a variety of other systems.
