METHOD AND KIT FOR CONTRACEPTION WITH GnRH-ANTAGONIST AND PROGESTIN

摘要

A method of providing contraception for and regulation of the menstrual cycle of a gonadal female mammal by a) administering thereto about once a week throughout her menstrual cycle an amount of a GnRH-antagonist effective to block folliculogenesis but less than the amount thereof required to block hormonogenesis; also administering prior to the end of that cycle an amount of a progestin effective to produce a secretory endometrium; and b) then terminating the progestin administration, thereby inducing menses.
