title: Low dose injectable contraceptive norethisterone enanthate 20mg monthly--I. Clinical trials.
abstract: Clinical trials were undertaken with an injectable low dose progestational contraceptive, norethisterone enanthate 20 mg monthly (Net-en - 20). Data from the study indicate that Net-en - 20 is an effective contraceptive with lower incidence of menstrual cycle disturbances than the currently used injectable progestogens. There was a prompt return of fertility after the withdrawal of the drug. Net-en - 20 did not have any adverse effect on maternal nutritional status as assessed by anthropometric indices of nutritional status, and clinical sign of nutritional deficiencies or on lactational performance as assessed by mothers' impression on milk output and mean duration of lactation.
