Hello, I have gone through the query and understood your concern. Pain during intercourse or dyspareunia , can be caused due to several causes and infection of the cervix and/or the vagina is one of them. The other possible causes are a retroverted uterus where the ovaries are prolapsed into the pouch of Douglas and pain is experienced on contact, cysts of the ovary, adnexal masses, polyps of the uterus and cervix, which often bleed etc. Appropriate management can be initiated after a complete appraisal. The finding of fluid in the pouch of Douglas in the sonogram indicates ovulation. As of now, there is no evidence of any infection. The occurrence of epithelial cells in abundance needs further evaluation. Hope this helps.
