Figure3 Relationship between progesterone levels and the number of retrieved oocytes in GnRH-a and LE GnRH-ant groups. In the PSM 2 cohort, progesterone levels on the trigger day increased by 0.05 ng/mL with an increase in every retrieved oocytes in the LE GnRH-ant group ( 0.05 ng/mL [95% CI 0.04, 0.06], P < 0.001), whereas an increase of 0.02 ng/mL was observed in the GnRH-a group ( 0.02 ng/mL [95% CI 0.01, 0.03], P < 0.001) (Figure3), with P for interaction was 0.0002, which suggest, with increased retrieved oocytes, women in the LE GnRH-ant group had a greater increase in progesterone levels than women in the GnRH-a group. Some researchers have suggested using three serial blood tests in a row as a better diagnostic tool, but even with this method its difficult to get precise results. It is not abnormal for progesterone levels to reach 85-90ng/ml during the first and second trimester, dropping to approximately 45ng/ml in the third trimester as the body prepares for birth. Figure2 and Figure3 show that with increased eggs, women in the LE GnRH-ant group had a greater increase in progesterone levels than women in the GnRH-ant group or the GnRH-a group. The currently available results are contradictory as progesterone levels >20 ng/ml (possibly due to an escape ovulation and subsequent embryo-endometrial asynchrony) on the day of transfer have been associated with decreased ongoing pregnancy and live birth rates ( Kofinas et al., 2015 ), while an optimal mid-luteal progesterone range Ovulation is the only way that your body can produce progesterone (more on that below).
