Male contraceptive testosterone enanthate is a hormone ester, it can inhibit pituitary gonadotropin release, promote, so that the Leydig cell secretion of endogenous testosterone decreased, eventually reached the purpose of blocking spermatogenesis. The Chinese Academy of animal experiments on monkeys found, weekly 1 injections of testosterone enanthate, apoptosis of monkey sperm cells began a week after fifth weeks to reach the peak of apoptosis of spermatogenic cells. Clinical trial of 308 volunteers also showed that the effect of testosterone enanthate pill for Asian men was significantly higher than that of white people. In this study, although the sperm reduction rate did not show racial differences, but Asians than whites on hormone induced suppression of spermatogenesis is more sensitive, more than 95% of the Asians can achieve no sperm, but only 40% to 70% of Caucasians become azoospermia.
 

Testosterone enanthate is a long-acting contraceptives, can be administered through a variety of ways (2 times a week to 1 times per week, 3 per 200 ~ 500mg, intramuscular injection), through more than 100 volunteers, the results show that the weekly intramuscular injection of 250mg, after 10 weeks can make the most of the men have no sperm azoospermia or severe oligozoospermia, sperm count can restore withdrawal after a certain time, with adverse reaction. If the injection interval extended to 10 ~ 12D or more, with double dose effect is not ideal.

Pharmacokinetic studies showed that this product injection immediately after a supraphysiological level of blood after peak blood concentration decreased rapidly, indicating the necessity of administration every week; the peak blood may directly stimulate spermatogenesis, so some of the volunteers fails to achieve significant oligozoospermia, sperm density decreased after a few volunteers can rise again.

Testosterone enanthate only injections 1 times per week, like than testosterone propionate is superior; but even so, it is hard for most people to accept. The other two kinds of testosterone, testosterone propionate and cyclohexane carboxylic acid testosterone, also need to be injected 1 times a week.
