There are many bizarre medical cases and medical mysteries, but this is something you may not have heard before. This is the story of a 15-year-old girl form Lesotho, a country within South Africa, who became pregnant without having any vaginal opening. How Did She Know About Her Pregnancy?The girl was admitted in the hospital due to the complaints of abdominal pain. Tests revealed that she was nine month pregnant. What came as a shocker that she had no vaginal opening, thus never had sexual intercourse. This left doctors amused, wondering how she may have gotten pregnant? She had a rare birth defect called distal vaginal atresia.What is Distal Vaginal Atresia?This is condition where the vagina is closed or absent. This condition occurs with other developmental problems in a female baby. Most often the baby also has Bardet-Biedl syndrome, Fraser Syndrome or Rokitansky-Mayer-Küster -Hauser syndrome. Bardet-Biedl syndrome is a rare disorder affecting many parts of the body. Loss of vision, obesity, kidney problems and intellectual disorders are common characteristics of the syndrome. Fraser syndrome is a rare disorder affecting development starting before birth. Babies born with Fraser syndrome typically have eyes that are completely covered by skin and usually malformed, fingers and toes that are joined together, and abnormalities of the urinary tract. Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome is a disorder in females causing the vagina and uterus to be underdeveloped or absent. It is often associated with kidney anomalies. This condition often accompanies a cloacal malformation, the surgical treatment which includes a variety of vaginal replacement techniques. People with distal vaginal atresia do have menstruation, but the blood does not exit, which forms blockage and buildup within the uterus. This condition is called hematometra or hematocolpos, which can cause pelvic pain and discomfort. This is a rare condition which affects 1 in 10,000 to 15,000 female children.How Did She Become Pregnant?While her body does not have a vaginal opening, but she does have a uterus, which means she can get pregnant if semen is injected and fertilized through in-vitro fertilization. However, this was not the case with her. The girl later revealed that while she did notice her body change, she "did not believe she was pregnant." However, when she was told she was pregnant, she delivered her child though a C-section delivery. In later interviews, she revealed that she had suffered stab wounds to her abdomen shortly after she had performed oral sex on her partner. At that time she confided in a nurse that her ex-partner had violently attacked her, when he found her in act with the current partner. The medical team that attended her then concluded that it could be due to the stomach would which may have allowed the sperm she swallowed to reach her reproductive organs. This may have resulted into an unexpected conception. Another shocker is that sperm does not survive in the digestive acid that stomach produces. However, the doctors believe that the sperm may have survived as at that time the girl was malnourished and the acidity levels in her digestive system may be low.
