Regarding the mechanism through which LE elevates progesterone, we hypothesised LE inhibited the production of oestrogen (mainly oestradiol), resulting in the accumulation of oestrogen synthesis precursors and androgens (e.g., testosterone and androstenedione) (14). The dose of LET should be increased to 5 mg and then 7.5 mg/day in subsequent cycles in cases of absent ovarian response. Among them, 1,186 cycles followed a gonadotropin-releasing hormone-agonist (GnRH-a) or gonadotropin-releasing hormone-antagonist (GnRH-ant) protocol.
