Summary
The purpose of the research study is to learn more about the regulation of reproductive
hormones in adult men. We would like to understand what role testosterone and estradiol play
in controlling the release of LH (lutenizing hormone) and FSH (follicle stimulating hormone).
Testosterone and estradiol come from the testes, and LH and FSH are released from a gland in
the head called the pituitary.
Men involved in the study will have detailed evaluations that involve overnight stays in the
hospital and frequent blood sampling. The men in the study will also be receiving medications
that affect the levels of various hormones in the body. This will allow the researchers to
learn how various hormones influence each other. Men that participate in the study will
receive medical evaluations and monetary compensation. Information gathered from this study
will help in the development of new treatments for infertility and potentially new hormonal
forms of contraception.
