Recent reports suggest that children born after intracytoplasmic sperm injection performed for male factor infertility are at increased risk of congenital malformations and chromosome aberrations. To explain these observations, we hypothesized that infertile men may be more likely than fertile men to have genetic abnormalities. We studied 750 severely oligozoospermic men (sperm count <5 million/ml) who were candidates for intracytoplasmic sperm injection, and 303 fertile men. We analyzed the peripheral blood karyotype, the Y chromosome long arm for detection of microdeletions in the azoospermia factors, and mutations in the cystic fibrosis gene and the androgen receptor gene. We also analyzed sperm for chromosome aneuploidies among the 421 ...
