A male contraceptive preparation is disclosed. The contraceptive preparation consists essentially of 1,2,3-trihydroxypropane in solution in a suitable carrier such as distilled water or saline solution. The method of contraception comprises injecting the contraceptive preparation into the testes. The 1,2,3-trihydroxypropane has been found to act as a potent inhibitor of spermatogenesis, resulting in long term infertility, with no apparent effect on libido, secondary sex characters, mating behaviour and hormone levels. There are no observed side effects and no observed effects on other aspects of reproductive and hormonal biology.
