Your Eggs and Fertility
For National Infertility Awareness Week, we’re looking at the top five causes of infertility and what you can do to overcome them. Ovarian disorders are the most common cause of female infertility. What are these disorders? Can you still have a biological family?
Common Ovarian Disorders
Getting pregnant naturally is not a simple process. When a woman ovulates, a mature egg is released by one of her ovaries. An egg can be fertilized by sperm in the fallopian tubes, becoming a zygote, and then travels down to the uterus, while the cells continue to divide. If the embryo implants in the uterus the woman becomes pregnant. Problems with the eggs are one of the major reasons for infertility. Some common disorders are:- PCOS—Polycystic ovary syndrome. PCOS affects one in 10 women of childbearing age and is caused by an imbalance of reproductive hormones. With PCOS, the eggs may not develop as they should, or you may not ovulate every month, and you may have cysts in the ovaries. PCOS causes missed or irregular menstrual periods. PCOS is also linked to other serious metabolic problems like diabetes, high blood pressure, and unhealthy cholesterol. It’s not clear if PCOS causes those issues, if the problems cause PCOS, or if other factors cause PCOS and the metabolic problems. Other symptoms of PCOS include weight gain, acne, too much hair on the face, chin or other parts of the body, and thinning hair or hair loss on the scalp. It’s not clear what causes PCOS. Several factors are thought to play a part, including genetics and insulin resistance.
- Endometriosis—When tissue similar to the tissue in the uterus (endometrium) grows in other parts of the body where it doesn’t belong, it’s known as endometriosis or “endo”. Often the tissue is found on the ovaries, fallopian tubes, and the outside of the uterus. Symptoms include very heavy menstrual periods, pain during sex, chronic pain in the lower back or pelvis, bleeding or spotting between periods, and infertility. No one knows for sure what causes endometriosis, although one theory is that retrograde menstrual flow can send uterine tissue into places where it shouldn’t be like the fallopian tubes. Endometriosis can make it harder to get pregnant, although no one knows exactly why it does.
- Diminished Ovarian Reserve—Diminished ovarian reserve is the loss of reproductive capability due to the number and quality of eggs. It’s normal for the quantity and quality of your eggs to decrease over time. Most women experience diminished ovarian reserve by menopause, but it is often a cause of infertility at age 40 or after, and affects some women earlier than that. The primary cause is aging, but it is also associated with cigarette smoking, ovarian surgery, and cancer treatment.
