Activité antigonadotrope de l'acétate de chlormadinone chez la femme en période d'activité génitale

Discussion and conclusion. - Chlormadinone acetate induces anti-gonadotropic activity which is similar to other nor-progesterone and nor-testosterone derived progestins. This activity is shown at first cycle when the drug is used from day 5; when the drug is used from day 8, cycle 2 or 3 must be waited for in order to obtain the same result.
