Mmmm... If I remember correctly, fertility doesn't start to incline dramatically until after about six months to sometimes a year, depending on the individual? I guess it matters as to how "potent" you were beforehand. But usually it is recommended to think of sperm-banking before you even start, that way you know you ARE fertile. Me, I am not really all that worried because I don't even think I am fertile to begin with. I mean, my parents forced me to have two surgeries down there to "fix me" because I supposedly "was not developing the right way" and because they were not sure if I would be fertile, which is why they made alterations. Sadly the said alterations have left me with near-constant pain, with no chance of relief, since medication doesn't help and doctors refuse to touch the area other than to paralyze it. That is like one of the reasons why I'm going this route, after all. But what can you do? In your case, though, I'd say to get it done as soon as possible if having kids is important to you. You can take that two ways. Either "do the deed" or get it banked. Honestly your best bet is to consult a medical professional, like your endocrinologist, or go see a fertility clinic. They can give you a better answer. But I do know that one's hormonal balance is an integral part of their fertility. I believe it is the same for men and women. Oh, and I am happy that you got the help that you needed and that you didn't get any flack from the school. It seems that trans these days are having an awfully lot of issues with them. Glad you aren't one of them. ^_^
