Health Problems That Impact Ovarian Function
Health Problems That May Harm or Block Fallopian Tubes
  • Endometriosis —Uterine tissue implanted on other pelvic structures can get in the way of functioning.
  • Sexually transmitted diseases—Infections, such as gonorrhea or chlamydia , often don't have symptoms in women. If left untreated, they can lead to pelvic inflammatory disease. This may cause scarring that blocks the tubes.
  • History of ectopic pregnancy —When a fertilized egg starts to grow in the tube, it can cause the tube to burst. As it heals, scar tissue may block the tube and lower fertility.
Other Health Problems

Any chronic health problem may lower the chances of a successful pregnancy.
