Acquired Gynaetresia is underreported in developing countries and is usually due to harmful cultural practices. It may result from obstructed labor or labor trauma. This is a rare case report of a 26-year-old P1 + 0 who presented with no penetration during coitus and history of amenorrhea about 1 year and 7 months after cesarean delivery. Failed attempts at vacuum extraction were made before surgery. She was investigated and a diagnosis of Gynaetresia with cryptomenorrhea was confirmed. She had vaginoplasty and menstrual and sexual functions were established. Postpartum genital examination should be ensured, no matter the mode of delivery to ensure Gynaetresia is diagnosed early and managed promptly.
