Gonadotropin secretion in the second half of the menstrual cycle a comparison of women with normal cycles luteal phase defects and disturbed follicular development

, : Gonadotropin secretion in the second half of the menstrual cycle a comparison of women with normal cycles luteal phase defects and disturbed follicular development. Clinical Endocrinology 32(1): 25-32

In order to study the relationship between episodic gonadotrophin secretion and alterations of ovarian hormone secretion, we examined women with normal menstrual cycles (n = 26), luteal phase defects (n = 10) or disturbed follicular oestradiol secretion (n = 8) as established by daily (except weekends) determinations of oestradiol and progestone. Pulsatile gonadotrophin secretion was studied during the luteal phase or the second half of the menstrual cycle sampling at 15 min intervals for 12 h. LH and FSH mean concentrations and LH pulse frequency were significantly (P < 0.01) increased in the group with disturbed follicular development in the presence of decreased oestradiol (E2) and progesterone (P4) levels. In women with luteal phase defects mean LH and FSH concentrations and pulsatile LH secretion showed a nonsignificant trend to lower values in the presence of significantly decrased P4 concentrations during the luteal phase.
