The best thing to do is consult a specialist. The thing about hormones is we all have a different mix, so only a trained professional can advise something specific. The most important thing is not to do DiY, because then you may not realize effects on fertility until it is too late.
I do know that according to a brochure I read the only two irreversible effects are the growth of breast tissue and infertility, but I also know that some people become fertile again after stopping. The only way to know if that is backed by fact is to talk to a specialist. Also, plenty of people store genetic material ahead of time. That's what i'm looking into. Good luck with your journey!
