Triphenyltin is an organotin compound that has been used extensively as an antifouling biocide and as an agricultural pesticide. Certain organotin compounds act as endocrine-active agents and have been reported to affect reproduction in mollusks and mammals. Here we studied the histopathological effects of 2 or 6mg triphenyltin chloride (TPTCl)/kg b.w. on the reproductive tissue and the thymus ...

s:2022:"Background: Cryopreservation is an important option for preserving the fertility. We examined the reactive oxygen species (ROS) production, total antioxidant capacity (TAC) and developmental competence, of vitrified isolated mice pre-antral follicles as an alternative method for restoring fertility. Materials and Methods: The 140-160 μm pre-antral follicles mechanically isolated from ov...

BACKGROUND Ovulation-inducing factor in semen (OIF/NGF) influences ovulation and CL form and function in camelids and, remarkably, in cows. To test the hypothesis that the luteotrophic effect of OIF/NGF is mediated by an increase in trkA receptors in the ovulatory follicle and early CL, a study was designed to characterize the spatial and temporal distribution of trkA in ovarian follicles and C...

the aim of this study was to evaluate the concentrations of reproductive hormones in blood plasma and in follicular fluids of different sized follicles during various stages of the estrous cycle in holstein cattle. jugular blood samples from 42 adult holstein cattle were collected immediately after the slaughter. antral fluids from small (4-5 mm), medium (6-9 mm) and large (10-20 mm) follicles ...

Background: In the past 2 decades, the survival rates for many of the malignancies that affectyoung women have significantly improved. For many of these malignancies, survival rates exceed 80-90%. Therefore, the remote effects of cancer treatment have recently gained worldwide interest, andthe protection against iatrogenic infertility caused by chemotherapy assumes high priority. Busulfan is a ...

Abstract Study question Can oral administration of antioxidants improve follicle survival in human ovarian tissue through reduction oxidative stress a xenotransplantation model? Summary answer Daily for 7 days post-transplantation had positive effect on grafted tissue. What is known already Today cryopreservation and autotransplantation an established fertility preservation method many centres....

the effects of dietary inclusion of medicinal plants’ by-product mixture on performance, the relative internal organ weight, ileal microbial counts, and small intestinal and liver morphologic alterations in laying hens receiving different omega-6 to omega-3 ratios as a 2×3 factorial arrangements with three levels of plants’ by-product (zero, 2.5 and five percent) and two omega-6 to omega-3 rati...

Background: Histological and histometrical effects of Fennel Essential Oil (FEO) on ovary structure were studied during postnatal development in female wistar rats. Materials and Methods: For this purpose, the female rats, after parturition divided in control, sham and experimental groups with equal number of female pups for each mother at random. Sham 1 and experimental 1 groups consisted of m...

Background: Infertility problem affects 20-30% of young couples. One of the known causes of spermatogenesis disorder is chemotherapy in patients with cancer which its side effect may last up to the end of the life. The aim of the present study is to investigate the effect of GnRH on viability of ovarian follicles defect produced by anticancer drug. Materials and Methods: In the present study ad...

background: congenital toxoplasmosis is one cause of abortion. infection can disrupt ovarian cycles and because toxoplasmosis is an infectious disease may have a similar effect on the ovaries. the purpose of this study was to investigate the pathological changes in the ovaries due to toxoplasmosis.   methods: tachyzoites of toxoplasma gondii were harvested from peritoneal fluid of mice, experim...
