Re: Why can't they transplant female sex organs to a male

Part of the answer to this question is contained in a recent response here having to do with ovulation in women.

To begin with, surgical transplantation into the male of certain parts of the female reproductive system is feasible but would be extremely difficult. However, such transplants could not function naturally even if the reproductive system could be successfully transplanted completely. Like the male reproductive system, that of the female is controlled by hormones produced and secreted in other parts of the body. In certain respects the female homone system associated with the brain (called the neuroendocrine system) is much more elaborate than the male's. So in theory, for a transplanted female reproductive system to operate naturally in a male two parts of the female brain (called the hypothalamus and pituitary) would also have to be tranplanted into the male brain. This is because the hypothalamus and pituitary control ovulation in the ovaries.

Thus the complete answer to the question: "Why can't they transplant female sex organs to a male?" is. Female sex organs could be transplanted to a male but it would involve elaborate abdominal, muscle, nerve, plastic and brain surgery. Even if all of this could be done, the resulting system would probably never work.
