CONTEXT: Adolescents' dual use of condoms and hormonal contraceptives is low, and the motivations underlying their decisions to combine contraceptives are not understood. METHODS: To examine how p...
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...
Eleven men, aged 21 to 60 years, with Hodgkin's disease have been studied before, during, and after chemotherapy. Blood samples were obtained for hormone analyses. In all 11 patients FSH levels rose...
Five intact male mongrel dogs, characterized by an episodic secretory pattern of LH and normal serum testosterone concentrations, were actively immunized against LHRH by subcutaneous injections of 2...
The effectiveness of intratesticularly injected bacille Calmette Guérin (BCG) as an antispermatogenic agent was examined by light microscopy in rats after three, six, ten, twenty, and 56 days and in...
The influences of follicle-stimulating hormone (FSH), gonadal steroids, and culture time were studied in relation to inhibin B production by Sertoli cells of immature rats cultured in vitro. Serto...
Spermatogenesis continues after long-term hypophysectomy (Hx), but massive cell degeneration prevents seminiferous tubules from attaining the full complement of cells. One objective of this study ...
A quantitative analysis of germ-cell populations in normal, hypophysectomized (Hx), and Hx-hormone-treated animals was undertaken during periods of regression that were characterized as intermedia...
The potential for follicle-stimulating hormone (FSH) to promote germ-cell survival and the cellular sites of FSH action were studied using a gonadally maturing (pubertal), hypophysectomized (Hx) rat...
Descent of the testes is a complex event mediated by hormonal and mechanical factors. At present we hypothesize that testicular descent occurs as the result of the secretion of descendin from a no...
Studies of protection of testicular function from cyclophosphamide with hormonal pretreatment have been limited by the lack of a convenient model for cyclophosphamide-induced inactivation of stem ...
This study analyzed the hormonal requirements necessary for the development of primate testicular peritubular cells. Alpha-smooth muscle actin, as a specific differentiation marker for peritubular c...
Previous investigators have suggested metabolic cooperation between Sertoli and peritubular cells. This study concerns Sertoli cell and peritubular myoid cell interactions in terms of synthesis of...
Serum follicle-stimulating hormone (FSH), luteinizing hormone (LH), and testosterone levels and secretory capacity of the in vitro stimulated testis were determined in control and bilateral cryptorc...
Polyclonal antibodies have been generated to investigate the localization, tissue and species distribution, androgen regulation, and ontogeny of a protein secreted by mouse seminal vesicle, designat...
