For binary logistic regression model, the early onset LH peak (LH ≥ 12.455) was the dependent variable, whereas the number of Gn days, total Gn doses, duration of infertility, BMI, number of collected oocytes, basal levels of FSH, LH, E2, P, and T, numbers of 2PN, number of high- quality embryos, number of days from Gn initiation to antagonist addition, E2 and P levels on the day of hCG were the independent variables (Table 5). Here, PLOD1 is linked to Infertility.
