My experience with hormone replacement therapy (HRT) was very positive. I began treatment at age 47, right at the onset of menopause. I’ve read that starting HRT around the beginning of menopause is recommended. However, there have been many changes in medical opinions regarding HRT as studies continue to evolve. I'm surprised that you have a doctor who is approving this treatment, as most doctors have been opposed to HRT for quite a long time. We were born with estrogen; why wouldn't we continue? I was on HRT for 35 years & felt great; I hated to stop, but since I was estrogen positive & taking AR's, it was suggested that I discontinue at age 73. I wish you well; live your life.
