[Changes of the endometrium during oral hormonal contraception with ethinyl estradiol sulfonate and norethisterone acetate or d-noregestrel].

48 fertile women took in three weeks 1 mg ethinylestradiolsulfonate weekly and in the 4th week 10 mg norethisterone acetate, respectively d-norgestrel in different dosages (0,5 mgs, 1,0 mgs, 1,5 mgs or 3,0 mgs). On this 48 women 69 abrasiones were made between the first and 37th treatment cycles in order to estimate the endometrium. Ethinylestradiolsulfonate caused for the most part a proliferation of endometrium, which reached to a glandulare cystic hyperplastic endometrium. We did not observe a reduction of the endometrial respond to this depot-estrogen in dependence on the time of taking. Norethisterone acetate and d-norgestrel effected on a different proliferated endometrium a secretory transfer mation always.
