Associations of selected meiotic program initiation pathway gene polymorphisms and the risk of idiopathic male infertility.

SNPs, single-nucleotide polymorphisms; OR, odds ratios; CI, confidence interval.

a

Subjects consisted of proven fertility men with semen volume ≥2 ml, sperm counts ≥20×106/ml and sperm motility ≥50% motile sperm.

b

Subjects consisted of idiopathic infertile men with sperm counts <20×106/ml.

c

Subjects consisted of idiopathic infertile men with sperm counts = 0/ml.

d

Subjects consisted of idiopathic infertile men with sperm counts from 0.1 to 20×106/ml.

e

Subjects consisted of idiopathic infertile men with sperm counts ≥20×106/ml.

f

ORs were obtained from multivariate logistic regression analysis.

g

Two-sided χ2 test for genotype distributions between cases and controls.
