A method of immunization of human males to achieve contraception is provided which includes the step of administering, periodically, predetermined amounts of, non-primate, highly purified FSH having a biologic potency of at least 1,000 I.U. (International Units)/mg, an LH contamination of below 11 I.U./mg and a TSH contamination of less than 0.1 I.U./mg, to a human male until his sperm production declines below about twenty million per cc. FSH is the Follicle Stimulating Hormone; LH the Luteinizing Hormone; and TSH the Thyroid Stimulating Hormone.
