Background: In modern countries today, herbal medicines are known to help in the treatment of various diseases, as rich sources of antioxidants and minerals.
The stages of spermatogenic cells killed by the single and fractionated administration of AMSA, an acridine derivative used in cancer chemotherapy, have been identified in the mouse. A wide range of...
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...
Existing data concerning the effects of x-irradiation on spermatogenesis in man were analyzed and the results were compared to published data on the mouse. Testicular x-irradiation produced a transi...
The effects of chronic treatment with hCG (100 I.U.s.c. every second day) on testicular morphology, LH receptor levels and concentration of steroid intermediates of the 4 and 5 biosynthetic pathwa...
The effects of a combination of a progestin, levonorgestrel (LNg), and estrone (E1), on exocrine and endocrine testicular function were examined in adult men. The mode of administration was subc...
Following the recent observation that chronic treatment with [D-Ala6, des-Gly-NH210]LHRH ethylamide, a potent LHRH agonist, leads to an almost complete degeneration of seminiferous tubules in the ra...
Studies using exogenous high-dosage testosterone (T) or a combination regimen of physiologic T plus high-dosage levonorgestrel (LNG) administration in normal men have shown that oligoazoospermia (...
Germ cell development (spermiogenesis in particular) in the adult rat is known to be testosterone dependent. Recently we proposed a role for the 5alpha reduction of testosterone to dihydrotestostero...
Recent evidence suggests that growth hormone (GH) may enhance physiologic processes, such as spermatogenesis, in addition to causing classical anabolic effects. We have previously shown that testost...
A rodent model was used to study the degree and dynamics of potential spermatogenic alterations during both acute and chronic phases after experimental spinal cord injury (SCI). Sexually mature Spra...
Levels of the hGSTM3 glutathione S-transferase (GST) subunit in testis of the human fetus and infant were found to be only a small fraction of those in adults. To understand these observations and...
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...
