Enzyme-linked immunosorbent assays for 17β-estradiol (A) and progesterone (B). Samples with analyte levels below the level of quantification and above the level of detection were assigned the value LOQ/2. Significance was assessed by comparing outcomes with a two-tailed t-test assuming equal variance between groups. Data are presented as mean ± SEM, n = 7–9, *Significantly different (p < 0.05) from filtered air controls
