Abstract

PIP: This study investigates possible changes in serum-prolactin levels in lactating women using the Progestasert system as compared with women fitted with a copper T device and lactating mothers not using any contraceptive method. 46 females (28-35 years of age, parity 1-6) were divided into 2 major groups: 1) 26 menstruating and lactating women (further subdivided into a) control group of 11 normally menstruating women without any contraception; b) 9 Cu T 200 users; and c) 6 Progestasert users); 2) amenorrheic and lactating mothers subdivided into 8 Progestasert users, and 12 Cu T 200 users. No significant differences in the premenstrual and menstrual mean prolactin values were observed in any of the groups. With the onset of menses, a uniform rise in prolactin levels was observed in 3 groups, but was significant only in the Progestasert group. Serum prolactin levels in lactating and amenorrhiec mothers 2 months after delivery showed no significant changes when Cu T 200 and Progestasert IUD users were compared. Further research on this subject should include a matched group of lactating and amenorrheic mothers.
