Living with Mullerian aplasia

A condition in females in which the uterus is small or missing and periods do not start.

Understanding Mullerian aplasia

Mullerian aplasia is a condition that affects the female reproductive system, caused by abnormal development of the Mullerian ducts.

The Mullerian ducts are structures in the embryo that develop into the uterus, fallopian tubes, cervix, and upper vagina. Females usually have an underdeveloped or absent uterus and normal external genitalia. Breasts and pubic hair develop normally at puberty, but menstruation does not begin by age 16. They are unable to have children. Higher-than-usual androgen levels can cause acne and facial hair, and kidney differences may be present. It is noticed in the teen years or adulthood.
