Some of the causes of infertility in women include fallopian tube blockage, uterine fibroids, tubal infection, and endometriosis. Blocked fallopian tubes, caused by STIs and the build-up of endometrial tissue, causes infertility because that is where most eggs are fertilized. Uterine fibroids is a disease caused by the hormones estrogen and progesterone. Tubal infection is caused by dangerous bacteria and STDs. Endometriosis is when the endometrial lining grows outside the uterus, damaging pelvic organs.
