On the other hand, basal serum AMH ≤ 4 (OR, 366 [95% CI, 25.05–4120], p< 0.001), primary infertility (OR, 2.36 [95% CI, 0.39–27.35] p = 0.68), infertility duration < 4 years (OR, 1.22 [95% CI, 0.30–4.77], p = 0.99), serum prolactin ≤ 20 (ng/mL) (OR, 0.69 [95% CI, 0.10–8.39], p = 0.55), and baseline LH/FSH (OR, 0.45 [95% CI, 0.10–2.36], p = 0.34) were correlated with a higher prediction of ovulation in CC- Placebo group (Table 4, Figure 3). This evidence concerns the gene PLOD1 and Infertility.
