Fig. 1From: Comparison of the predictive value of progesterone‐related indicators for pregnancy outcomes of women undergoing the short‐acting GnRH agonist long protocol: a retrospective studyProgesterone-related indicators and pregnancy outcomes in women with different ovarian responses. The serum P levels increased with the number of oocytes retrieved, and they were lowest among women with a poor ovarian response and highest among women with a high ovarian response. In the normal ovarian response group, there was no significant difference in the serum P or P/E2 between the pregnant and non-pregnant groups. The PFI and PMOI of the pregnant group were significantly lower than those of the non-pregnant groupBack to article page
