The Effects of Chlorpromazine on Reproductive System and Function in Female Rats

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, control and CPZ (n=8 per group). In the treated groups, CPZ was administered by gavage at doses of 3, 10 and 30 mg/kg per day for 28 days. On day 29 the animals were killed after which histopathological and histomorphometric analyses of the ovaries were performed. We evaluated the levels of prolactin serum, luteinizing hormone (LH), follicle-stimulating hormone (FSH), estradiol (E2) and progesterone. Results The ovaries of the test groups showed numerous atretic follicles of various sizes. CPZ caused a significant difference between the test groups and the control group (P
