Rather than asking us, you can do some of the research yourself.
I have spend about 4-5 hours the other day trying to find information on something another member posted that he/she said researched but when asked about it and how it works, a reply where you say of, you tried it yourself, but you don't know anything about interactions, what exactly happened and the like.
Basicly it was a reply with many shortcomings, and a reply with shortcomings is or can be harmful.
So Ill tell you what I DO know and I have a question too.
Why on earth would you even want to START with hormonal treatments?!
Any person with a bit of common sense would think you're insane and would never start such a thing.
The Pill - that which prevents the egg from being able to form an embryo when it comes in contact with sperm, is based on hormones. There either are hormones in there or it has ingredients that has an influence on your own bodies hormones.
When The Pill is taken for a long period of time and people decide to stop because they want to get pregnant a few things can happen. One of these is, the woman won't menstruate for a while. Another is, there are lingering symptoms relating to the Pill. This can indeed be difficulty to concieve and other issues.
Also, if you do any research on the Diana pill that was used last century, but BANNED because women who had children that took that pill, those children had severe deformities. Basicly. They didn't have any arms or legs but they may have had feet and hands.
Some ingredients and chemicals stay in the body and wont be gone for quite some time. Which also causes issues.
Now if you were so to say start hormonal treatment as a man to undergo gender change into a woman you could become very emotional. As one of the side effects.
And if you undergo treatment as a woman to become a man hormonally, with testosterone, you may become more agressive. Also apparently testosterone treatment is sometimes used for women when they want to build muscle for bodybuiling or something.
There are other types of hormonal treatments, like, if someone has breastcancer (or ovary and others) they "assume" it is hormonal reactive (they say they test it but I think they would prescribe such a thing more as a preventive measure anyway). Most times this treatment of that is to make a woman lose the menstruation cyclus aka enter the menopause.
What this treatment does to the brain.. well.. my mom described it like there was a cloud all that time in her head that she couldn't get rid of. She took these for 3 years or so before the doctor said she could stop the treatment as it didn't seem to suppress the remaining cancer anymore or something along that line.
Current Jewish cancertreatment is like this: Put people on toxins and hope they survive the treatment.
There are better ways to cure cancer but you'll have to look into this.
Healing is not a matter of physical healing, but also of mental and emotional.
Again, I am not going to spend 5 hours to answer your question. Type in topics on duckduckgo.com and surf a couple of pages. And then search any other questions you might have. You can even try google or bing or whatever else. Sometimes I search on startpage.com too. They do give results from google on the first page but you can visit the pages with a proxy and you can try searching in the images too.
