Before PSM, patients in the LE GnRH-ant group were older (P < 0.001) and had a higher BMI (P = 0.008) and a frequency of ovulation disorder and male factor (P < 0.001) than those in the other two groups (Supplemental Table1).

In this study, we hypothesised that late elevations in follicular blood progesterone might be owing to the following reasons: 1) An increase in progesterone secretion from the recruited follicles; the greater the number of follicles, the higher the progesterone level, which could be induced by any protocol; 2) pathological progestogen, which is related to the premature luteinisation of follicles and decreased follicle quality. I could be wrong, but Im not sure they letrozole or the trigger shot contribute directly to progesterone levels. A level of 30 nmol/L or more is a good result.
