Sequential hormone measurements after first trimester abortion in normal Nigerian women

This study looks at the dynamics of the pituitary hormones and progesterone in normal adult Nigerian females during their first postabortal cycle. Serial determinations of serum concentrations of luteinizing hormone (LH), follicle-stimulating hormone (FSH), prolactin (PrL) and progesterone were carried out on eleven normal Nigerian women during the first postabortal period after menstrual regulation. Nine out of the eleven subjects (82%) attained LH peaks within the first 22 days after menstrual regulation, seven had discernible FSH peaks and seven had serum progesterone concentrations greater than 6 nmol/l during the second half of the study period. Subjects probably ovulated during the first postabortal cycle; serial LH seems to be the most reliable index of ovulation in our subjects. We hope these data will aid in development of effective family planning strategies for women in the first postabortal cycle.
