It is possible to get pregnant with only one fallopian tube, but having a previous ectopic pregnancy is a risk factor for infertility.

An egg is released from one of the ovaries each month and swept into the tube where fertilization by the sperm takes place. An egg that is fertilized in the tube, instead of in the uterus, cannot fully develop. These are called ectopic pregnancies.

Ectopic pregnancies must be treated to prevent tubal rupture, a situation that can result in very serious internal bleeding. In some cases, ectopic pregnancies are treated with a medicine called methotrexate. This causes the abnormal tissue to dissolve. However, many cases require surgery to remove the pregnancy. If an ectopic pregnancy damages the tube beyond repair, the entire tube is removed.

Ectopic pregnancies often occur because the tubes were damaged by a previous pelvic infection (called pelvic inflammatory disease). The infection usually affects both tubes. This means the tube that didn't have the ectopic pregnancy may not be normal. Women with a history of an ectopic pregnancy have about a 30% to 40% risk of infertility. And they have about a 15% risk of another ectopic pregnancy if they do become pregnant.

Infertility caused by damaged fallopian tubes can be treated by bypassing the tubes. This is what happens with in vitro fertilization (IVF). This may be an option for you.

Clomid won’t help if the only identified fertility problem is damaged fallopian tubes. Clomid is a drug that stimulates the ovaries to produce eggs in women with failed ovulation.
