Peri‐Ovulatory Hormones
Are the LH levels of E2, LH, P associated with the probability of pregnancy?
Is there a threshold level above or below which the probability of pregnancy is decreased?

Serum LH Systematic reviews
Low endogenous LH levels caused by high antagonist doses
were associated with decreased probability of pregnancy
in a dose finding GnRH antagonist The Ganirelix Dose‐Finding Study Group, 1998
No association of LH levels probability of ongoing pregnancy beyond 12 weeks. Serum LH concentrations measured on stimulation D8 by percentiles
6 studies, n=1103 patients
Kolibianakis et al. 2006
Endogenous LH concentrations have no association with the likelihood of ongoing pregnancy using a recombinant FSH/GnRH antagonist protocol Serum LH concentrations measured on stimulation D8 by percentiles
6 RCTs n=1764 patients
