Infertility is when a mature, sexually active woman has unprotected sex during her fertile period for at least 1 year without getting pregnant.

There are so many causes of infertility in both men and women but we will be focusing on infertility in women.



  1. Failure to ovulate: 40% of all infertility in women is a result of the woman not ovulating. When this happens during unprotected sex there is no egg to be fertilized.
  2. Problems with menstrual cycle: irregular cycles or no cycle at all make it harder for a woman to get pregnant.
  3. Structural problems of the reproductive system: Structural problems usually involve the presence of abnormal tissue in the fallopian tubes or uterus. If the fallopian tubes are blocked, eggs are not able to move from the ovaries to the uterus and sperm is not able to reach the egg for fertilization. Structural problems with the uterus, such as those that may interfere with implantation, can also cause infertility.
  4. Infections: like sexually transmitted diseases can cause infertility in both men and women especially when is undiagnosed, untreated, and mistreated.
  5. Failure of the egg to mature properly: Ovulation is when a matured egg is released from the ovary once every menstrual cycle. When an egg is not matured, it may not be released, maybe released late, or may not be fertilized.
  6. Implantation failure: when the sperm fertilizes the egg, it is implanted in the uterus where the fetus starts developing. When it fetus doesn’t implant properly on the uterus there is a high chance the will miscarry.
  7. Endometriosis: is when the tissues found inside the uterus start to grow outside. Read more on the previous blog post.
  8. Polycystic Ovary Syndrome (PCOS): PCOS is one of the most common causes of female infertility. It is a condition in which a woman’s ovaries and, in some cases, adrenal glands produce more androgens (a type of hormone) than normal. High levels of these hormones interfere with the development of ovarian follicles and the release of eggs during ovulation. As a result, fluid-filled sacs, or cysts, can develop within the ovaries.
  9. Primary Ovary Syndrome (POI): POI is a condition in which a woman’s ovaries stop producing hormones and eggs at a young age. Women with POI ovulate irregularly, if at all.
  10. Uterine Fibroids: noncancerous growths that form inside the uterus. These growths can change the structure of the uterus making it difficult for fertilization, implantation, etc. to occur resulting in infertility.
  11. Autoimmune Disorders: Autoimmune disorders cause the body’s immune system to attack normal body tissues. Both men and women can make antibodies that attack sperm or the reproductive organs.
