Ground Skink (Scincella lateralis) testes were examined histologically to determine the testicular organization and germ cell development strategy employed during spermatogenesis. Testicular tissues were collected from 19 ground skinks from Aiken County, South Carolina during the months of March-June, August, and October. The testes consisted of seminiferous tubules lined with germinal epitheli...

The luminal part of the seminiferous epithelium, a tissue compartment protected by the blood-testis barrier, has been considered a site of immune privilege. However, there are reports describing the production of anti-microbial peptides and the expression of Toll-like receptors in cells present in the seminiferous epithelium, evoking the possibility that this tissue compartment is immunological...

Introduction: Recent advances in reproductive technology have brought hope of having a child to infertile men. Testicular sperm extraction (TESE) is an effective method that recovers intratesticular sperm from a small fragment of seminiferous tubules excised under microscopic surgery, followed by artificial fertilization. To increase the sperm retrieval rate in TESE, a navigation system that sh...

Effect of oral administration (25 and 100 mg/kg body wt/day, for 20 and 90 days) of fruit powder of Piper nigrum L. on the male reproductive organs of mice, Parkes strain, was investigated. Various reproductive end points such as organs weight, histopathology, sperm parameters, sialic acid and fructose contents, and fertility indices were assessed. Histologically, testes in treated mice, except...

Although multiple interactions of seminiferous tubules and the interstitial testicular tissue are known, correlation of cytokeratin 18 expressing Sertoli cells with interstitial changes has still not yet been reported. Considering this fact, we focused our investigation on changes of the adjacent interstitial tissue. A total sample of 51 testicular biopsies (from infertile patients) showing mix...

Objective(s): Pyriproxyfen as an insect growth regulator is widely used globally for pest management. There are reports on adverse effects of insecticides such as organ toxicity, endocrine disruptions, and teratogenicity in animals and humans. We aimed to investigate reproductive toxicity of pyriproxyfen in adult male mice.Materials and Methods:</stro...
