[Changes of serum hormone concentrations during oral contraception using monohormonal and combination preparations (proceedings)].

Hormone serum concentrations were measured in 9 women who used a combination preparation and 7 women who used Lyndiol. During combination preparation use the usual changes in the concentrations of gonadotropins and steroids were observed as well as a significant increase in prolactin production. This was indicative of suppression of ovulation. No change in the prolactin concentration was observed during Lyndiol use but FSH levels decreased steadily and very low LH peaks were observed. After initial increases the concentration of estradiol decreased markedly. After the 1st treatment cycle progesterone levels did not reach levels indicating normal corpus luteum function although after long-term use levels rose to 2-4 ng/ml which could indicate an abortive corpus luteum or luteinizing follicle.
