Prognostic value of serum progesterone and LH values on the day of hCG administration in IUI GnRH antagonist cycles

Abstract

Objetive: to evaluate the effect of LH surge and progesterone rise in IUI cycles under gonadotropin stimulation with GnRH antagonist coadministration on pregnancy rates (PR). Study Design: The population under study consisted of 152 women prospectively studied and subjected to IUI. Results The higher the progesterone cutoff value, the lower the PR were 26.5% and 10.9% when the cutoff was 1 ng/mL, 26.0% and 8.6% when the cutoff was 1.2 ng/mL, 25.6% and 7.1% when the cutoff was 1.4 ng/mL and 25.3% and 0% when the cutoff was 1.6 ng/mL. Conclusion: In IUI cycles under GnRH antagonist coadministration, serum progesterone levels over 1.0 ng/mL are associated with lower PR, the higher the progesterone levels, the lower the PR.
