Abstract
Objective: To study the effect of stress on the sexual behavior and its pathophysiological effects on some reproductive and endocrine functions in albino rats.
Methods: One hundred and twenty albino rats were included and divided into a control groupand three experimental sub-groups, which were subjected to sexual stress. Female rats were investigated for the cytological changes in the phases of the estrous cycle. All rats were observed for behavioral changes throughout the experiment. Histopathological examination of the thyroid, testes and ovaries and the assessment of thyroid and gonadal hormones in the sera of control and experimental rats were performed.
Results: Cytological examination revealed stopped estrous cycle in the diestrous phase in all female rats. Thyroid hormones revealed a decrease in the levels of triiodothyronine and thyroxin; however, non-significant changes were detected in the thyroid-stimulating hormone level in experimental rats compared to the controls. Gonadal hormones revealed a great discrepancy in their levels among both sexes.
Conclusions: The results of the present study show that sexual excitation is one of the stressful factors affecting sexual behavior, hypothalamic-pituitary-thyroid and hypothalamic-pituitary-gonadal axes as well as sex organs with secretory functions. Therefore, it is considered as a socio-pathological factor that needs more specific studies to further clarify its effects.
