Regulation of ovarian primordial follicle assembly and development by estrogen and progesterone: endocrine model of follicle assembly.

abstract：:The consumption of refined sugars continues to pose a significant health risk. However, nearly nothing is known about the effects of sugar intake by healthy women on the oocyte or embryo. Using rhesus monkeys, we show that low-dose sucrose intake over a 6-month period has an impact on the oocyte with subsequent effect...

Parallel to the in vivo findings, an impaired GH responsiveness to GHRF is evident in somatotropes from old rats of either sex. We report here that in anterior pituitaries ...
