Background Chlorpromazine (CPZ), an antipsychotic drug, is associated with increased risk of sexual dysfunction through increasing prolactin levels. The current study evaluates the effect of CPZ-induced hyperprolactinemia on ovarian follicular growth, gonadotropins, and alteration of ovarian source hormones. MaterialsAndMethods In this experimental study, animals were divided into four groups, ...

To investigate the significance of changes in ovarian inhibin in gonadal dysfunction with persistent estrus, female rats with persistent estrus were studied as animal model for polycystic ovaries (PCO). Newborn female Wistar rats treated with testosterone propionate s. c. (TP) and female rats raised under continuous light (LL) started at 9 weeks of age entered into continuous estrus 5 and 2 or ...

Germ cell development and primordial follicle formation during fetal life is critical in establishing the pool of oocytes that subsequently determines the reproductive lifespan of women. Fragile X-associated primary ovarian insufficiency (FXPOI) is caused by inheritance of the FMR1 premutation allele and approximately 20% of women with the premutation allele develop ovarian dysfunction and prem...

African elephants of reproductive age in zoos are experiencing high rates of ovarian cycle problems (>40%) and low reproductive success. Previously, our laboratory found that 1/3 of acyclic females exhibit hyperprolactinaemia, a likely cause of ovarian dysfunction. This follow-up study re-examined hyperprolactinaemia in African elephants and found the problem has increased significantly to 71% ...
