PurposeNumerous genetic and endocrine factors are involved in the process of testicular descent, but only a few genetic causes have been reported in human. The aim of this study was to investigate the density and distribution of single nucleotide polymorphisms (SNPs) anti-Müllerian hormone (AMH) and AMHRII receptors in cryptorchid patients and determine potential hormone imbalance connected with undescended testes by assessing the levels of AMH, Insulin-like factor 3 (INSL3) and inhibin B.Materials and methodsThe serum hormone levels (AMH, INSL3 and inhibin B) were compared in the two groups – cryptorchidism (n = 105) and control group (n = 58). The frequency of AMHRII −482 A > G, AMHRII IVS 10 + 77 A > G, AMHRII IVS 5–6 C > T, and AMH Ile49Ser polymorphisms among cryptorchid boys were compared with the control group.ResultsNone of the hormones levels were different between the cryptorchid and the control groups. All cases of IVS 5–6 C > T homozygote and heterozygote mutation were accompanied by an IVS 10 + 77 A > G and 482 A > G homozygote and heterozygote mutation. Interestingly, in most cases of all four polymorphisms, homozygote recessive genotype was associated with cases of cryptorchidism. However, the groups of patients were too small to draw definite conclusions.ConclusionThe AMHRII −482 A > G, AMHRII IVS 10 + 77 A > G, AMHRII IVS 5–6 C > T and AMH Ile49Ser genotypes should be determined in a much larger group of boys with cryptorchidism.
