How to check for congenital absence of vagina

Differential diagnosis of congenital absence of vagina, hymen atresia: The shape, size and thickness of the hymen hole vary from person to person. Generally, the hymen hole is located in the center and is half-moon-shaped. Occasionally, a septum appears, dividing the hymen hole into two halves, called a septum hymen or a double-hole hymen.

There are also membranes that are sieve-like and cover the vaginal opening, which are called sieve-like hymens. If the folds of the hymen are overdeveloped and become a hymen without holes, it is called hymen occlusion, which is the most common abnormal development of female reproductive organs. It can be diagnosed based on symptoms and signs.

Women who are 18 years old or older or whose secondary sexual characteristics have matured for more than 2 years but still have no menstruation. This condition is seen in congenital reproductive tract abnormalities such as uterine hypoplasia or absence, congenital ovarian hypoplasia or absence, primary pituitary hypogonadotropism, and congenital adrenal hyperplasia. In a few cases, pseudo-amenorrhea caused by lower reproductive tract atresia should be excluded. Girls who have not had menstruation by the age of 18 should go to the hospital for examination. The cause of amenorrhea should be determined as much as possible based on medical history, comprehensive physical examination, and necessary auxiliary examinations. Further treatment should be given according to different causes. For example, congenital uterine hypoplasia can be treated with oral administration of small doses of estrogen to promote development, and congenital developmental malformations (such as absence of vagina, vulvar malformation, and lower reproductive tract atresia) can be corrected surgically.

Prepuberty is often overlooked. If carefully examined, there may or may not be a hymen, a shallow depression at the hymen opening or a short and shallow lower vagina. With or without uterine dysplasia. If the uterus is dysplastic.
