The Progesterone Saga
Why?
You see, most of the doctors I've been too, associate Progesterone with pregnancy and menstruation, both of which unless one of us begins birthing another baby Jesus will ever have to deal with. But it's more then that. I've written about it, here and there, but it's clear that Progesterone effects much more then just the lining a women's reproductive tract. It effects sleep patterns, receptor sensitivity at the cellular level of thyroid and adrenaline, and can even effect a personas insulin and make someone diabetic, because the cell doesn't have the capability of absorbing glucose.
For all the things we're fond of estrogen, it's mostly an inhibitor to most of the bodies other chemicals. It requires the progesterone as a pathway to the cells, and without it you become like most post-menopausal women with out proper HRT, and get weak and less healthy.
In fact, (and the reason I write this) men have progesterone in their bodies similar to that of a females during most of the month. A female's progesterone level increase approaching menstruation in what's called the Luteal phase, but do you know where men get their progesterone? Their testicles. Something a transsexual whose gone through orchiectomy, vaginoplasty, won't have. Furthermore a small amount is produced in a person's glands, by which the precursor is testosterone. So if you're on an anti-androgen, you could be effecting your Progesterone levels.
Since most progesterone in males is created during testicular production of testosterone, and most in females by the ovaries, the shutting down (whether by natural or chemical means), or removal, of those inevitably causes a considerable reduction in progesterone levels.
So why Doctor?
Because it's one of the most important hormones produced in the male or female bodies. It's derived from either the testicles or the ovaries in women. In a transexual where they have neither, the importance of supplementing these chemicals via HRT is critical
