In medicine, hymenal atresia (Atresia hymenalis) is a congenital malformation of the hymen in which the vagina is completely closed by the hymen. It is therefore a form of gynatresia in which cavities or ducts of the internal female genital organs are closed by inhibition malformations .
The consequence of this occlusion is a symptom-free hydrocolpos with fluid accumulation in the vagina or hydrometrocolpos with fluid accumulation also in the uterus in newborns . This fluid consists of secretions from the maternal vaginal mucosa, which is hormonally stimulated.
With menarche , the first occurrence of menstrual bleeding in puberty , a hematocolpos occurs with a build-up of menstrual blood in the vagina or a hematometra (hematocolpos) with build-up also in the uterus. In these cases, the hymen is opened surgically.
