One of the reasons that questions like this tend to get stern answers is because along with the possible good outcomes of HRT, there are significant risks - and many of the changes are not reversable. Hence we are actually trying to save folks from possibly making a mistake they will regret.

As for HRT without anti-androgens, the fact is that estrogen, all by itself - with no other drugs, will cause all the affects people are talking about. The reasons we take a group of drugs is to get the maximum possible results - and to a small degree, to hurry things along. HRT isn't and Ala' cart menu; you get what you get, no choices. It cannot be tailored to result in breasts and not <fill in blank>. There are a few things that you can be sure of, regardless of what drugs you take.

One: you will be made sterile after a while. When ? No one knows, so if you want kids later, bank some sperm prior to starting therapy.

Two: you will lose some or all of your ability to have erections. How much ? Won't know till you get there. I've been on a seriously strong regime for 9 months and I can still get an erection with the right stimulation. I do that on purpose, weekly. As others have said, need those nerves working for later !!

Three: your body will stop producing much Testosterone and after a point, even if you stop the hormones, your body will not start testosterone production at a normal level again in your life. Hence you'd have to go on Testosterone shots or the like if you wanted off the HRT. Fact is you need to have one of the two hormones systems up and running for healthy living.

Four: breast development, regardless of all things, is a crap shoot. Most likely you'll get some, most likely not much. Even if you have some now ... You cannot not trust what people say they have, or pictures you see. Many exaggerate their results. Sure, there are some folks who get great natural results. As mentioned in other posts ... it is rare. Ask any GG about breast development and they will tell you that ya just don't know till it is done. The only way to increase breast size, for sure, is to get pregnant.

I do not mean to sound harsh or condescending ... it is just that HRT is serious medicine and is something that a person should consider carefully.
