摘要

Aim: To determine the ultrastructural effects of sildenafil on the female genital organs. Methods: Twenty female cycling Wistar albino rats weighing 250±20 g were randomly divided into two groups of 10 each. Rats of one group were gavaged with 0.5 mg·kg-1·d-1 of sildenafil 3 days in a week for 4 weeks and the other served as the controls. After cessation of treatment animals were sacrificed by cervical dislocation under methoxyflurane anaesthesia. The clitoris, vagina, uterus and bartholin glands were taken at the estrous and were fixed with 10 % formalin solution for light microscopy and 2.5 % glutaraldehyde and osmic acid for electron microscopy. Results: Under the light microscope, the fibrocollageous tissue was found increased, the capillaries enlarged and the connecting tissue elements increased in the corpus cavernosum in the treated group. On electron microscopy, increased connective tissue, fibroblasts with notched nucleus, shorten immature collagen fibers without striation were seen. Abundant
