title: Reproductive hormone profiles in regularly menstruating Sudanese women.
abstract: Venous blood samples were taken daily from 21 regularly menstruating Sudanese women throughout one complete menstrual cycle. FSH, LH, estradiol-17 beta and progesterone were assayed in all plasma samples and normal reference ranges were thus established. Fifteen subjects had a luteal phase of more than 12 days whilst in 3 subjects it was shorter. Two subjects were found to be hyperprolactinemic and one had an anovulatory cycle with an elevated LH. The plasma concentrations of estradiol-17 beta in the follicular phase and progesterone in the luteal phase were significantly lower in subjects with short luteal phase than in those with a luteal phase of more than 12 days. The hormonal profile of FSH, LH, estradiol-17 beta and progesterone throughout a normal menstrual cycle in regularly menstruating Sudanese women was similar to what has been reported in the literature for other ethnic groups.
