What kind of doctor treats Mullerian Aplasia?
A primary care doctor, such as a family doctor or pediatrician, is often the first to notice the condition and can order early tests. A gynecologist, a specialist in female reproductive health, usually manages care. Some people also see a geneticist or kidney specialist if other organs are affected.
What it is
Mullerian aplasia is a rare condition a girl is born with, also called Mayer-Rokitansky-Kuster-Hauser syndrome, or MRKH syndrome. In this condition, the uterus and cervix do not develop, and the vagina may be shorter than usual or missing. The ovaries, which make hormones and eggs, usually work normally. A person with this condition has female genes and looks female on the outside.
Symptoms
The most common first sign is that periods do not start by age 15 or 16. Doctors call this primary amenorrhea, meaning a girl has never had a menstrual period. Some people have a smaller or shorter vagina, which can make sex difficult or painful. Because the ovaries work normally, other signs of puberty happen on time, including breast growth and body hair. Some people with MRKH syndrome also have kidney, spine, or hearing differences.
Causes and who gets it
The exact cause is not known. It happens during early development before birth, when the reproductive organs do not form fully. Most cases are not inherited, so it usually does not run in families. It affects about 1 in every 4,000 to 5,000 girls.
How doctors diagnose it
Doctors start with a physical exam and medical history. An ultrasound or MRI can show whether the uterus and cervix are present. Blood tests check hormones and chromosomes to rule out other causes of missed periods.
Treatment
There is no treatment that creates a uterus. A shorter vagina can often be stretched over time using special dilators, which works for most people. Surgery is another option if dilators do not work. Counseling and support groups can help with the emotional side of the diagnosis.
When to see a doctor
See a doctor if periods have not started by age 15 or 16, if periods start and then stop, or if there is monthly belly pain without bleeding. Pain during attempts at sex should also be checked.
How a direct primary care or concierge doctor fits in
A direct primary care doctor is paid a flat monthly fee instead of billing insurance per visit. A concierge doctor works similarly but usually charges more and often also works with insurance. Either type can spend extra time with patients, order the first imaging and blood tests, and provide emotional support. When Mullerian aplasia is suspected, they would refer the patient to a gynecologist and coordinate follow-up care.
Common questions
Can a person with Mullerian aplasia ever have children?
Carrying a pregnancy is not possible without a uterus. Some people build a family through adoption or gestational surrogacy. Because the ovaries usually work, some people also use their own eggs with a surrogate.
Does Mullerian aplasia affect how female hormones work?
No. The ovaries usually make normal amounts of hormones, and puberty happens on time.
Is this condition painful?
The condition itself usually does not cause pain. Pain can happen if there are other problems, such as a blockage. Any belly pain should be checked by a doctor.
Can it be found before puberty?
Most cases are not found until periods fail to start in the teen years. Some are found earlier by chance during imaging for another reason.
