Estrogen hormones are responsible for female sexual development and function, such as breast development and the menstrual cycle. Estrogen levels rise and fall throughout the month, and then gradually wane as menopause approaches. Estrogen replacement therapy is sometimes prescribed at this point for depression and vaginal dryness. Studies have shown estrogen protects against nerve damage and brittle bones, but it also seems to play a role in endometriosis and certain female cancers.

Hormone Replacement Therapy
A few years ago, the use of hormone replacement therapy looked like a medical mess. For decades, women were told that HRT -- usually a combination of estrogen and progestin -- was good for them during and after menopause. Then, the 2002 results of the Women's Health Initiative study seemed to show just the opposite: hormone replacement therapy actually had life-threatening risks.
