Abstract
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.
Materials and Methods
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<0.05) on the amount of atresia and the size of the normal corpora lutea (CL). The increased dysfunction of the ovaries from the different groups depended on the amount of
CPZ administered. The serum concentrations of prolactin and progesterone significantly
increased (P<0.05), while the serum concentrations of estradiol, LH and FSH notably
decreased (P<0.05), depending on the CPZ dose. CPZ-induced animals had unsuccessful
mating and decreased pregnancy rate.
Conclusion
The present findings suggest that CPZ-induced disturbances not only depend
on prolactin level but the increased prolactin level is largely dose-dependent.
