Can you still get pregnant if you only have one ovary and one fallopian tube?
Having either just one ovary or just one fallopian tube can greatly reduce your chances of getting pregnant. However, it is indeed still possible to become pregant without intervention under certain circumstances. The most important factor is where the ovary and the tube are located in relation to one another.
Generally speaking, only one ovary will release a single egg each month. For a woman with two health ovaries, the ovaries take turns, although not in any recognizable pattern, as to which ovary will release an egg each month. If you have just a single ovary, it may release an egg every month. After the egg is released, it travels down the fallopian tube. This is the process known as ovulation. As long as you are ovulating, there is a chance that you may become pregnant.
Once the egg is in the fallopian tube, conception can occur. In the fallopian tube, sperm may fertilize the egg. Then, the fertilized egg travels to the uterus, where it implants and then stays until birth.
The fallopian tube adjacent to the ovary that releases the egg is generally where the egg is released. If you have only one ovary and one fallopian tube, and they are on the same side, there is a good chance that you can become pregnant. If your one ovary is on the opposite side of your one fallopian tube, odds are against it. While it is possible for an egg released from an ovary to be transported by the other fallopian tube, it is extremely rare. In addition, if you have a single fallopian tube and it is on the opposite side of your single ovary, you are at a greater risk of having a tubal pregnancy, also called an ectopic pregnancy.
For a woman with one ovary and one fallopian tube who has not been able to conceive, IVF (in vitro fertilization) may be a treatment option.
