Developmental disorders of the female reproductive tract are problems in a baby girl's reproductive organs that occur while she is growing in her mother's body.
A baby starts to develop its reproductive organs between weeks 4 and 5 of pregnancy. This development continues until the 20th week of pregnancy.
The development is a complex process. Many different things can interrupt the process. How severe your baby's problem is depends on when the interruption occurred. In general, the earlier development problems occur in the womb, the more serious the problem.
Problems in the development of a girl's reproductive organs may be caused by:
For example, some babies may have a genetic defect that prevents their body from producing a substance called 21-hydroxylase. If a developing baby girl lacks this substance, she will be born with a uterus, ovaries, and fallopian tubes, but her external genitals will look like those found on boys. See: Congenital adrenal hyperplasia
Certain drugs that the mother takes can pass into the baby's bloodstream and interfere with organ development. One drug known to do this is diethylstilbestrol (DES). Doctors once prescribed this medicine to pregnant women to prevent miscarriage and early labor. However, scientists learned that baby girls born to women who took this drug had an abnormally shaped uterus. The drug also increased the daughters' chances of developing a rare form of vaginal cancer.
Sometimes, a developmental disorder can be seen as soon as the baby is born. It may cause life-threatening conditions in the newborn. Other times, the condition is not diagnosed until the girl is older.
The reproductive tract develops close to the urinary tract and kidneys. It also develops at the same time as several other organs. As a result, developmental problems in the female reproductive tract sometimes occur with problems in other areas, including the urinary tract, kidneys, and lower spine.
Other developmental disorders of the female reproductive tract include:
Symptoms vary according to the specific problem. They may include:
The doctor may notice signs of a developmental disorder right away. Such signs may include:
The belly area may be swollen or a lump in the groin or abdomen may be felt. The doctor may notice the uterus does not feel normal.
Tests may include:
Doctors often recommend surgery for girls with developmental problems of the internal reproductive organs. For example, a blocked vagina can usually be corrected with surgery.
If the baby girl is missing a vagina, the doctor may prescribe a dilator when the child reaches young adulthood. A dilator is a device that helps stretch or widen the area where the vagina is supposed to be. This nonsurgical process takes from 4 to 6 months. Surgery may also be done to create a new vagina. Surgery should be done when the young woman is able to use a dilator to keep the new vagina open.
Doctors have reported good results with both surgical and nonsurgical techniques.
Treatment of cloacal abnormalities usually involves multiple complex surgeries to fix any problems with the rectum, vagina, and urinary tract.
If the birth defect causes life-threatening complications, the first surgery is done shortly after birth. Surgeries for other developmental reproductive disorders may also be done while the baby is an infant. Some surgeries may be delayed until the child is much older.
Early recognition is important, particularly in cases of ambiguous genitalia. Careful consideration should be given before assigning a gender -- that means, before you decide that child is a boy or girl. Treatment should include counseling for the parents and, eventually, the child. For specific treatment information, see the articles on intersex and ambiguous genitalia.
Support is important for families of children who are diagnosed with abnormalities of the sexual and reproductive organs. Experts also recommend counseling and support groups for the children themselves, as they get older.
Different support groups may differ in their thoughts regarding this very sensitive topic. Look for one that supports your thoughts and feelings on the topic.
Support organizations include:
Cloacal abnormalities can cause life-threatening complications at birth.
Potential complications may develop if the diagnosis is made late or is wrong. Children with ambiguous genitalia who are assigned one gender may later be found to have internal organs related to the sex opposite from which they were raised. This can cause severe psychological distress.
Undiagnosed problems in a girl's reproductive tract can lead to infertility and sexual difficulties.
Other complications that occur later in life include:
Call for an appointment with your health care provider if your daughter has:
Pregnant women should be extremely careful not to handle any substances that contain male hormones. It is also important for pregnant women to check before taking any type of medication or supplements such as DHEA.
However, development problems with a baby may still occur, even if the mother makes every effort to ensure a healthy pregnancy.
