While the use of letrozole in fertility preservation patients has a favorable effect on estrogen levels, no benefit is seen for progesterone levels which are high and comparable with progesterone levels after standard COS in IVF patients. What should progesterone level be on letrozole? Meanwhile, an increase in the number of follicles means an increase in the accumulation of precursors in the presence of LE.

Based on different ovulation induction protocols, 1,133 infertile women who underwent ovarian stimulation were divided into the following groups: GnRH-a (383), GnRH-ant (390), and LE GnRH-ant (360) (Figure1). No use, distribution or reproduction is permitted which does not comply with these terms. Is letrozole during ovarian stimulation useful in breast cancer patients undergoing fertility preservation to reduce early luteal progesterone levels following GnRH-agonist trigger? A study has reported that in patients with high responses (the average number of retrieved oocytes is 1213), the progesterone levels significantly increase and the proportion of patients with a progesterone level >1.5 ng/mL also increases significantly (19).

Progesterone levels on trigger day were converted into a binary variable, with 0.55 as the boundary. I ovulate on my own but my numbers are usually around 9 so the doctor put me on Femara to give a me a stronger ovulation and she seemed to think that might help withthe low progesterone. doi: 10.1016/j.fertnstert.2018.02.128, 27. doi: 10.1016/j.fertnstert.2013.08.045, 28. doi: 10.1016/j.fertnstert.2010.12.065, 31. Patients in the LE GnRH-a group presented higher progesterone levels on trigger day (1.23 0.91 ng/mL vs 0.98 0.61 ng/mL, P < 0.001), with higher proportion of patients with a progesterone level > 1.5 ng/ml (25.45% vs 12.70%, P < 0.001); higher P/E2 ratio (0.72 0.53 vs 0.32 0.21, P < 0.001), with higher proportion of patients with a P/E2 ratio > 0.55 (51.94% vs 11.31%, P < 0.001); higher POI (131.23 109.62 pg/mL vs 97.28 89.77 pg/mL, P < 0.001), lower oestradiol levels on trigger day (2,347.71 1,781.67 pg/mL vs 3,658.56 1972.96 pg/mL, P < 0.001), and less retrieved oocytes (13.30 8.56 vs 16.78 8.47, P < 0.001) than those in the GnRH-a group.
