Chlamydia is one of the most common sexually transmitted diseases. It often has no symptoms at all, yet can do a lot of damage to a woman's reproductive system. The fact that chlamydia is easily treated by a course of antibiotics does no good to women who have no idea that they were infected with this "silent" disease. Chlamydia can lead to damage throughout the reproductive organs, and blocked fallopian tubes resulting in ectopic pregnancies are not a rare complication. Experts on the topic say that "no less" than half of all ectopic pregnancies are caused by a chlamydia infection, a figure that rises even more for women in their young twenties.
Chlamydia has the ability to damage the reproductive organs most often the fallopian tubes as the infection rages around. The bacterial infection damages healthy tissue and leaves scar tissue behind instead. It is no surprise, when you think about it, that scarring inside the fallopian tubes has the ability to prevent a fertilized egg from moving down into the uterus, thus causing a tubal pregnancy. Tubal pregnancies always result in pregnancy loss, and can also quickly become life-threatening for mothers. If timely treatment is not provided, the tube will rupture and the internal hemorrhage that results can easily be deadly. In many cases, the removal of the embryo from the tube will also require part of the tube itself to be removed, and can cause future infertility.
These are all compelling reasons to go through STD testing before getting pregnant, or in the early stages of pregnancy if you already conceived. If you are monogamous, and convinced that your partner is too, you could still have chlamydia if you had a previous relationship. STD testing is no more than a little bit of a hassle, but treatment could prove to be life saving.
