Genetics of male infertility: role of androgen receptor mutations and Y-microdeletions.

Abstract excerpt

INTRODUCTION: Although infertility affects about 5% of the male population, its cause in most cases is uncertain. Normal spermatogenesis depends on a sequential cascade of genetic events triggered by factors encoded by the sex chromosomes. To determine the contribution of genetic aberrations to male infertility, the X-linked androgen receptor gene and the Y-chromosome were examined for mutations in a large cohort...
