The resumption of menstrual cycles after abortion
Abstract
PIP: Hormonal studies were conducted on 18 women who had 1st trimester therapeutic abortions. Levels of urinary HCG/LH declined rapidly immediately following the abortion, with the low plateau reached about 14 days after the abortion. A surge of LH in the 16-22 day postabortion period in 15 of the women indicated the imminence of ovulation. Assays of the plasma levels of estradiol-17B and progesterone reinforced this observation. It is concluded from this study that ovulation occurs fairly soon after a 1st trimester abortion. These findings accorded with earlier studies using endometrial biopsies. It is, therefore, recommended that effective contraception begin immediately after abortion.
