Premenstrual syndrome (PMS) has a wide variety of signs and symptoms, including mood swings, tender breasts, food cravings, fatigue, irritability and depression. It's estimated that as many as 3 of every 4 menstruating women have experienced some form of premenstrual syndrome.

Polycystic ovarian syndrome (PCOS) is estimated to affect 1 in 10 women of childbearing age and is one of the most common causes of infertility. Symptoms include irregular periods or no periods, excessive hair growth, weight gain, and acne.

Millions of women are misdiagnosed with infertility every year because few doctors are doing the advanced testing needed to discover the root cause of their inability to get pregnant, which can be hormonal.

This stress-related condition stems from chronic elevation of adrenal hormone levels. Symptoms might include chronic fatigue, allergies, and insomnia.
