Table 4 Comparison of HLA-DRB1 and -DQB1 allele frequencies in patients with bilateral and unilateral cryptorchidism and in control individuals.

From: Weak association of anti-sperm antibodies and strong association of familial cryptorchidism/infertility with HLA-DRB1polymorphisms in prepubertal Ukrainian boys

Allele HLA-DRB1/DQB1 Controls N = 60 Cryptorchidism
    Bilateral N = 20 Unilateral N = 40 p/pc OR C.I.
