Reproductive hormone concentrations during r-hPRL or placebo injections. LH, FSH and estradiol (E2) concentrations (mean ± SE) in normal women during 7 days of treatment with placebo (n = 12; black bars) and r-hPRL (n = 9; white bars) in the early (EFP), mid (MFP) and late follicular phase (LFP). There were no differences in hormone concentrations at any cycle stage between the two groups.
