Abstract
Liver-function tests were carried out on 52 women who had been receiving long-term treatment with a progestational and ovulation-inhibiting substance (Orgametril), or its combination with estrogen in 2 different concentrations (Lyndiol and Lyndiol 2.5), for the management of menorrhagia, endometriosis, or dysmenorrhea or for contraceptive purposes. No laboratory or clinical indication of hepatic dysfunction during treatment with these products could be found.
