Comparison of the levels of E2 and P4 in the follicular fluid of the various infertile groups. (A) E2 content in the follicular fluid. (B) P4 content in the follicular fluid. The follicular fluid of the patient was collected, and the contents of E2 (pg/mL) and P4 (ng/mL) in the follicular fluid were analyzed by radioimmunoassay (RIA).
