  • Method of reducing mammalian fertility and drugs therefor
    Patent number: 4081533
    Abstract: The pre-ovulatory surge of luteinizing hormone from the pituitary gland is selectively suppressed or eliminated by introducing nonapeptide, 8-arginine vasotocin, or the tripeptide, propyl-arginyl-glycinamide, into the subject. Analogs and related peptides also exhibit a similar inhibitory effect. This anovulatory effect in the female, or reduction in spermatogenesis in the male, results in loss of fertility.
