I'm 69, and believe my hormone related transition has slowed to the point where I can start to reduce my hormone intake. There are risks with any drugs, but it's important to note that the risks often quoted for MTF hormones originate from the old Women's Health Initiative study, which was based on Premarin and medroxyprogesterone, both synthetic hormones with relatively higher risk profiles. Doctors familiar with more modern studies based on bioidentical hormones realise the risks are much lower, and are more comfortable maintaining menopausal levels post transition.
Please consider that if the source of natural hormone production has been removed, or made inoperative, it is important to maintain some hormones to regulate body functions, particularly bone density. Also, hormones do have an impact on the rate of ageing, so if you have none, you will age more quickly. So you need to find the balance between risk and advantages, and my doctor is happy for me to work towards E levels just under 200pg/ml for the rest of my life. Ultimately we need to decide between risk and reward with input from our doctors.
Hugs,
