All male partners were referred to a complete andrological work-up with physical examination, determination of hormones, HIV testing and semen analysis. Cytogenetic analysis wascarded out in both partners by means of standard techniques using cultured lymphocytes from peripheral blood. Re-suits: Among the 305 couples, 10 men (3.2%) and 10 women (3.2%) showed constitutional chromosomal aber-rations, including reciprocal translocations (n = 7), Robertsonian translocations (n = 3), inversions (n = 3), otherstructural aberrations (n = 4) and sex chromosome aberrations (n = 3). In addition to the impaired sperm count inmost of the patients, a tendency to an increased proportion of spermatozoa with acrosome defect was observed. Con-clusion: Chromosomal aberrations may contribute to the low fertilization and pregnancy rates in the infertile couples.(Asian J Androl 2000 Dec; 2: 293-296)展开更多
