The History of Estrogen Therapy.

INTRODUCTION

Menopausal hormone therapy (MHT) has proven an effective treatment for the amelioration of symptoms of menopause. The idea that a substance was the missing factor in a woman's body after menopause dates to the 1800s, when cow ovarian tissue was injected into German women in a successful attempt to reverse the sexual symptoms of menopause. The early 1900s saw the rise of commercialized menopause "treatments" that ranged in substance and even theoretical efficacy. The role of estrogen was first accurately described in Guinea pigs in 1917 by Dr. Papanicolaou.

AIM

To tell the detailed history of how estrogen was discovered and the controversy surrounding MHT.

METHODS

A literature search was conducted using PubMed to identify relevant studies and historical documents regarding the history of estrogen therapy.

RESULTS

The history of estrogen supplementation and its controversies are interesting stories and relevant to today's ongoing investigation into hormone replacement.

CONCLUSION

The controversy of MHT remained until the first randomized trials examining MHT in the early 1990s that suggested MHT is cardioprotective in postmenopausal women, although this conclusion was contradicted in subsequent trials. In the present day, MHT is approved only for short-term use for the symptomatic treatment of menopause. Kohn GE, Rodriguez KM, Hotaling J, et al. The History of Estrogen Therapy.
