Sexual & reproductive health

Overview

Polycystic ovary syndrome (PCOS) occurs when more male hormones than normal are produced by a woman's ovaries or adrenal glands. As a result, cysts (fluid-filled sacs) develop on the ovaries.

The cause of PCOS is unknown. However, genetics, is thought to play a role. Some studies have shown if a mother has PCOS, there is a 50% chance her daughter will have PCOS. Women who are obese are at an increased risk for polycystic ovary syndrome.

There is no cure but some medications can help control certain symptoms. Birth control pills can be given to help regulate menstrual cycles, reduce male hormone levels, and help with acne. Other medications can be prescribed to decrease hair growth and increase ovulation.

5-10% of women of childbearing age are affected by PCOS. However, PCOS can occur in girls as young as 11 years old.

As many as 5 million women in the United States may have PCOS however less than 50% of women diagnosed. This leaves millions of women undiagnosed.

Symptoms

  • Infertility (not able to get pregnant) because of not ovulating. PCOS is the most common cause of female infertility.
  • Infrequent, absent, and/or irregular menstrual periods
  • Excess hair growth on the face, chest, stomach, back, thumbs, or toes
  • Cysts on the ovaries
  • Acne, oily skin, or dandruff
  • Weight gain or obesity, usually around the waist
  • Difficulty losing weight
  • Male pattern baldness or thinning hair
  • Patches of skin on the neck, arms, breasts, or thighs that are thick and dark brown or black
  • Skin tags — excess flaps of skin in the armpits or neck area
  • Pelvic pain
  • Anxiety or depression
  • Sleep apnea — when breathing stops for short periods of time while asleep
  • Decreased sex drive
  • Increase in stress levels

Causes & risk factors

The cause of PCOS is unknown. However certain factors such as genetics, can play a role.

PCOS is associated with an imbalance of hormones. Polycystic ovary syndrome (PCOS) occurs when the ovaries make more androgens than normal. Androgens are male hormones that females make, but high levels of these hormones will affect the development and release of eggs during ovulation.

Some experts believe there is a link between insulin and PCOS. Insulin is a hormone that controls the change of sugar, starches, and other food into energy for the body. Many women with PCOS have too much insulin in their bodies due to an inability to use insulin correctly. Excess insulin seems to increase androgen production.


 

When to get help
