Background: Formaldehyde is a chemical that used in fixed tissues and bodies. Formaldehyde during dissection of cadaver, evaporate and be released. Studies have shown that the gas increase endogenous opioids, nitric oxide and cytokines in plasma. These impacts can affect on gonadotropin hormones. The aim of this study was to investigate possible changes in gonadotropin and epithelial cells of t...

Carica Papaya (CP) plant (paw paw) is largely used for its curative benefit and now being exploited as an anti-fertility agent. The testicular histomorphometric correlation visa versa function is yet to be fully understood. This study aimed at quantifying the effects of aqueous extract of the bark of CP on the testes of adult Sprague–Dawley (S-D) rats. Ninety adult 6-8 weeks old male S-D rats w...

BACKGROUND Momordica charantia (M. charantia) seed has been supposed to have an antifertility property but mechanisms underlying the infertility effect have not been investigated. OBJECTIVE We investigated the antifertility effect of M. charantia ethanol seed extracts on reproductive toxicology and seminal and plasma testosterone in male Wistar rats. MATERIALS AND METHODS The control group ...

Objectives: Quantify the distribution of collagen and analyze the seminiferous tubules diameter in the testis of patients with cryptorchidism, to verify if the previous use of human chorionic gonadotrophin (hCG) affects these structures. Material and Methods: Samples of parenchymal tissue of cryptorchid testis obtained during peroperative biopsies were collected from 26 patients. Sixteen sample...

CD34-positive stromal cells are distributed in various organs including breast, Fallopian tubes, thyroid gland, colon, pancreas, and uterine cervix. To elucidate the distribution of CD34-positive stromal cells, smooth muscle cells, and myofibroblasts in normal human testis, we examined 48 testes obtained by autopsy and operation, including five fetal, one neonatal, and 42 adult cases without ev...

The blood-seminiferous tubule barrier is responsible for maintaining the unique microenvironment conducive to spermatogenesis. A key feature of the blood-testis barrier is selective permeability to solutes and water transport, conferred by the Sertoli cells of the seminiferous tubules (SMTs). Movement of fluid into the lumen of the seminiferous tubule is crucial to spermatogenesis. By Northern ...

BACKGROUND Cadmium chloride which is potentially toxic is currently used in industry. The toxic effects of cadmium on testes have been reported to range from apoptosis to necrosis, with different effects on fertility. This research aimed to study the effect of different doses of cadmium on testicular tissues at acute stage by light and electron microscopy. METHODS Cadmium chloride was injecte...
