Bones of Women with POF May Be Protected by Hormone Treatment

hormone treatment may protect bones of women with POF Auremar/PhotoSpin

Women whose ovaries stop normal functioning before they are 40 are at higher than normal risk of osteoporosis or brittle bones. A recent study at the National Institutes of Health Clinical Center in Bethesda, Maryland offers new hope that hormone replacement therapy can help reduce this risk.

Primary ovarian insufficiency (POI), which is also known as premature ovarian failure (POF), is a condition that results when a woman’s ovaries stop producing enough estrogen. Estrogen is a hormone or chemical messenger that helps regulate a woman’s menstrual cycle and sexual function.

Women with POI may have symptoms similar to women in menopause including irregular or missed periods, hot flashes and difficulty getting pregnant because eggs are not released regularly.

POI differs from menopause in that women with POI may still have irregular periods and may get pregnant. Women in menopause stop having periods and cannot get pregnant.

Osteoporosis is a serious complication of POI. The hormone estrogen helps the body keep bones strong by maintaining the density of bones. Healthy bone looks like a honeycomb made up of bone with small holes or spaces.

Without enough estrogen, the body is not able to replace bone tissue as fast as it is needed. This makes the spaces or holes in the honeycomb larger and causes bones to become brittle and break more easily.

POI may occur for no apparent reason, which is known as spontaneous POI, or it may be caused by another medical disease, surgery, chemotherapy or radiation. Spontaneous POI affects approximately 1 percent of women under the age of 40.

Women with POI have abnormally low levels of several reproductive hormones including estradiol, which is a type of estrogen, as well as testosterone. They also have measurably lower bone mineral density, which is a risk factor for osteoporosis.

Researchers at the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) used bone density scans on the hip and lower spine of women with POI between the ages of 18 and 42.

The 145 women participating in the study were randomly divided into two groups.
