Alterations in follicular dynamics and steroidogenic abilities induced by heat stress during follicular recruitment in goats

Follicular dynamics in Serrana goats.

Twenty-two Serrana goats were studied through two successive estrous cycles in order to characterize their follicular dynamics during the breeding season. The ovaries of the goats were scanned daily by real-time ultrasonography and all follicles >or=3mm were measured and classified. The data were classified by the number of follicular waves per goat to test the hypothesis that temporal and morp...

//follicular Recruitment, Selection, and Dominance

The term “recruitment” has been used to describe the process by which the follicle departs from the resting pool to initiate growth. However, some authors also use this term to describe the engagement of a cohort of antral follicles into further growth. To avoid confusion, McGee and Hsueh suggested that the first situation be called initial recruitment and the latter, cyclic recruitment.[133] C...

Oxidative stress, biochemical alterations, and hyperlipidemia in female rats induced by lead chronic toxicity during puberty and post puberty periods

Objective(s):Lead (Pb) is a toxic metal inducing many destructive effects leading to a broad range of physiological, biochemical, and neurological dysfunctions in humans and laboratory animals. Materials and Methods: Here, we investigated the effect of chronic exposure to Pb (50 mg/l) on oxidative stress, hepatotoxicity, nephrotoxicity, and lipid profile of two different age groups of female r...

Effect of Goat Follicular Fluid on in vitro Production of Embryos in Black Bengal Goats

The study was undertaken to elucidatethe beneficial effects of goat follicular fluid (gFF) added to maturation and culture media on in vitro maturation, fertilization and post-fertilization development of oocytes in Black Bengal goats. Follicular fluid and oocytes were collected from slaughter house goat’s ovaries using the aspiration technique. Media were prepared using TCM-199 supplemented wi...
