In comparisonwith the fertile group, the expression of the INSR genewas 2.95 times (P=0.005, 95% CI: 0.397-4.010) higherand the IRS-1 gene was 2.92 times (P<0.0001, 95% CI:0.204-1.719) higher than that of the infertile group withthe age of ≤30. The gene discussed is IRS1; the disease is Infertility.
