vaginal atrophy

vaginal atrophy /vaj″ənəl/ , a postmenopausal condition of gradually declining tissue activity in the female reproductive tract. It is caused by a cessation of follicular inhibin and estrogen secretion. This leads to decreased negative feedback on the release of follicle-stimulating hormone and luteinizing hormone by the anterior pituitary gland. Tissue effects related to estrogen deficiency include atrophy and dystrophy of the vulva and vagina, pruritus vulvae, dyspareunia, cystourethritis, ectropion, and uterovaginal prolapse.
