.... This review focuses on the hypothesis that testicular germ cell cancer, which originates from germ cell neoplasia in situ, is of foetal origin and associated with other male reproductive problems through a testicular dysgenesis syndrome, also including foetal origin of impaired spermatogenesis, hypospadias...

... reproductive hormone gonadotropin-releasing hormone (GnRH) has been shown in several studies to be expressed in hamartomas resected from children with CPP (n = 8) [ 4,5,6,7,8,9 ]. Furthermore, Valdueza et al. [ 10 ] observed that hamartomas from three patients who had seizures but not CPP did not express GnRH...

...P.M. Wise; N.G. Weiland; K. Scarbrough; M.A. Sortino; I.R. Cohen; G.H. Larson Changes in female reproductive function occur relatively early during the life span in many mammalian species. Therefore, this physiological system is an excellent model system in which to study the effects of age...

... slightly depressed the growth of the reproductive organs and pituitary prolactin levels, respectively. Again, these effects were negated by removal of the pineal gland. 6-Hydroxymelatonin was without influence on any of the parameters of reproduction that were measured. © 1977 S.

... the inhibitory effects of blinding on reproduction and nearly completely the depressant action of light deprivation on pituitary prolactin levels. In the second study the melatonin-beeswax pellets were implanted subcutaneously into blind hamsters every 2 weeks. The pellets contained either 1 mg, 500, 100, 50...

...E.J. Clegg; G.A. Harrison Patterns of reproduction in human populations living at high altitudes are discussed. While there appears to be little impairment of gametogenesis in either sex in resident highland populations, there is good evidence that pregnancy may be interrupted and in those...

...Michiyoshi Taga; Hiroshi Suginami Cell adhesion is essential for the regulation of many cellular functions. The adhesion molecule plays a critical role as a fundamental substance in various processes of reproduction such as trophoblast-endometrial interaction. Our understanding of the physiology...

... and body energy balance. Apart from the function of leptin in the central nervous system on the regulation of energy balance, it may well be one of the hormonal factors that signal to the brain the body’s readiness for sexual maturation and reproduction. During late pregnancy and at birth when maternal fat...
