The proliferation and differentiation of possible Leydig cell precursors in adult rats were studied after destruction of the existing Leydig cells with EDS or after daily treatment with hCG. After 2...
Testosterone is aromatized to estradiol in both peripheral tissues and the central nervous system. Various authors have suggested that this conversion in the male may be prerequisite for the regulat...
Involvement of endogenous estrogen in the regulation of gonadotropin and testosterone secretion was investigated in adult rams. Groups of four rams were either passively immunized against estradio...
the effect of high doses of testosterone propionate (TP) on the development of the first spermatogenic wave was systematically analyzed to determine the period of maximal susceptibility to testoster...
Mechanical activity of the rat caput epididymidis in vitro was recorded using a videomicrography system. The effects of prostaglandin (PG)F2 alpha, PGE2, and aspirin on caput epididymidis contractil...
While it is generally accepted that GnRH stimulates release of pituitary gonadotropins, it is not clear what regulates synthesis. The orchiectomized immature rat, with sustained high plasma levels o...
Steroid regulation of pituitary LH and FSH secretion in the male may be mediated via the direct action of testosterone, or via the conversion of testosterone to either dihydrotestosterone (DHT) or e...
We have examined hormonal regulation of ornithine decarboxylase (ODC) activity in decapsulated rat testis, isolated testicular interstitial cells, and purified Leydig cells under defined conditions ...
Exposure of immature male rats to 5% (w/v) ethanol as the sole drinking fluid from weaning age (21 days of age) resulted in a delay in balanopreputial separation (41.3 ± 1.4 days versus 37.6 ± 2.0 d...
Prolactin receptor content of ventral prostates of young mature (4-5-month-old), adult (12-13-month-old), and aged (24-27-month-old) untreated AXC rats was 677 ± 151, 826 ± 242, and 213 ± 59 (P < 0.01...
Studies were carried out to determine the effect of various numbers of testosterone-filled polydimethylsiloxane (PDS)capsules on plasma concentrations of testosterone and FSH in acutely orchidectomi...
Factors controlling the appearance in the epididymis of basal cells and their expression of macrophage antigens were examined by ligating the efferent ducts to prevent the entry of spermatozoa in ad...

In the present study, a possible role of ceramide in the regulation of Sertoli cell function was investigated. Intracellular ceramide levels were increased by adding N-acetylsphingosine (C2) or by i...
Sperm acrosomal exocytosis is the result of a complex set of signal transduction pathways activated physiologically by the egg's extracellular matrix, the zona pellucida. In the mouse, the zona pe...
