Pulsatile LH secretion in premenopausal women in the control and NK3Ra-treated cycles (n = 8). (A) Illustrative LH pulse profile from one participant who underwent blood sampling every 10 minutes for LH for 8 hours with no NK3Ra (closed circles) and on day 7 of NK3Ra treatment (open squares). Mean (B) LH pulse frequency, (C) basal (nonpulsatile) LH secretion, (D) mass of LH per pulse, (E) pulsatile LH secretion, and (F) relative orderliness or regularity of LH secretory pattern were compared between the control and NK3Ra-treated cycles. Data are given as mean ± SEM. *P < 0.05. ApEn, approximate entropy.
