This study is being offered to all participants of the ACY-5 study as an optional addition to the male contraceptive study in which they participated. Participation is voluntary.
The goal of our contraception study (ACY-5) is to develop a hormonal regimen where in all individuals enrolled achieve azoospermia (zero sperm). However, early data demonstrated that some individuals have persistent sperm in their semen despite treatment. We hope to be able to determine whether differences in intratesticular hormone levels account for persistent sperm production in men who do not reach counts of zero as compared to those who do in the male contraceptive study. This study will measure testosterone levels in the testes of men who are participating in male contraceptive studies. Testosterone will be measured in a small amount of testicular fluid at the end of the study treatment phase after sperm counts have been reduced to zero or very low levels.

The purpose of this research study is to help in the development of male contraception (birth control).
A single-arm trial to demonstrate that the blood levels of medroxyprogesterone acetate are adequate for effective contraception when Depo-SubQ Provera 104 is injected in the upper arm
The purpose of this research study is to understand the effects of testosterone (T) and estrogen on stem cells in the blood. The knowledge will be used to help understand the effects of T...

The symptoms of low testosterone frequently overlap with psychiatric complaints including depression and fatigue. Testosterone repletion has been shown to improve mood symptoms in men with low testost...
Steroidal compounds related to TESTOSTERONE, the major mammalian male sex hormone. Testosterone congeners include important testosterone precursors in the biosynthetic pathways, metabolites, derivatives, and synthetic steroids with androgenic activities.
Methods of contraception in which physical, chemical, or biological means are used to prevent the SPERM from reaching the fertilizable OVUM.
A potent androgenic metabolite of TESTOSTERONE. Dihydrotestosterone (DHT) is generated by a 5-alpha reduction of testosterone. Unlike testosterone, DHT cannot be aromatized to ESTRADIOL therefore DHT is considered a pure androgenic steroid.
Behavior patterns of those practicing CONTRACEPTION.
A potent androgenic steroid and major product secreted by the LEYDIG CELLS of the TESTIS. Its production is stimulated by LUTEINIZING HORMONE from the PITUITARY GLAND. In turn, testosterone exerts feedback control of the pituitary LH and FSH secretion. Depending on the tissues, testosterone can be further converted to DIHYDROTESTOSTERONE or ESTRADIOL.
