The testicular response of Ile-de-France rams actively immunized against estradiol (E2) was evaluated during both the ovine nonbreeding season (spring) and breeding season (autumn). Plasma concentrati...
The effects of ethanol consumption on the morphology of the seminiferous epithelium, with particular emphasis on Sertoli cell ultrastructure, were examined during and following pubertal developmen...
This study was designed to explore the relationship between the intratesticular distribution of testosterone and spermatogenesis by completely destroying the Leydig cells of mature male rats with in...
Steroidogenesis and spermatogenesis decrease in aging Brown Norway rats. We therefore hypothesized that there must be accompanying morphological changes taking place in the seminiferous tubules of...
Spontaneous germ cell death during spermatogenesis is an important event, and the usefulness of the seminiferous epithelium as an in vivo model to study apoptosis has been evidenced. Nevertheless, the...
Using multiple HPLC steps, a protein of 67 kDa (estimated by gel permeation HPLC) was purified from Sertoli cell-enriched culture medium that consisted of two dissimilar subunits of 9 (alpha chain...
This study was designed to determine the effects of short episodes of mild hypothermia on cell apoptosis in the testis of the adult rat. Apoptosis was assessed by in situ DNA 3'-end labeling in the ...
The effects of 3 Gy local X-irradiation on the adult rat testis were studied together with exact determination of the radiation dose distribution in the testis. Seminiferous tubule segments were i...
The duration of the cycle of the seminiferous epithelium is believed to be under genetic control rather than being influenced by other factors. However, the frequencies of certain spermatogenic stag...
Aging of the mammalian testis is often accompanied by loss of germ cells and, as a result, decreased daily sperm production. It is currently unknown whether cell loss is the result of aging-related ch...
A computer program called Stages was written to aid the tracking of germ cells and stages forward and backward through time in the cycle of the seminiferous epithelium. The program incorporates the ...
The authors examined the possibility that ethane 1,2-dimethanesulphonate (EDS) has a cytotoxic effect on spermatogenesis that is not secondary to androgen withdrawal resulting from the well known cy...
Testes of adult Sprague-Dawley rats were irradiated locally by 3 Gy of 4 MeV X-rays produced by a linear accelerator. This type and dose of radiation gives an even distribution through the testis an...
Spermiation, the release of late spermatids from the Sertoli cell, is disrupted by a number of toxicants. Control of the spermiation process, and the proteins that interact to adhere mature spermati...
During spermatogenesis, the movement of germ cells across the seminiferous epithelium is associated with extensive junction restructuring. Yet the underlying mechanism (or mechanisms) that regulates...
