Anal intercourse and idiopathic infertility: Anatomical considerations and authors’ perspective

Identification of causes of infertility could improve the chances for the management. The unexplained or idiopathic causes represent up to 30% for the infertility cases. One of such causes might be the unprotected anal intercourse due to the high possibility of lacerations and injuries occurring through the thin mucosa of anal canal. Escape of sperms into the injured female tissues might encourage her body to develop antibodies against the seminal content of male partner and causing infertility. Future studies are recommended to clarify such possibility as well as to develop a new contraceptive method depending on the immunity. *Correspondence to: Abdelmonem Awad Hegazy, Professor and Former Chairman of Anatomy and Embryology Department, Consultant of Obstetrics and Gynecology, Faculty of Medicine, Zagazig University, Egypt, E-mail: dr.abdelmonemhegazy@yahoo.com
