title: Meiotic studies in human semen. Report of 180 cases.
abstract: Meiotic studies can be carried out in the spermatogenic cells present in ejaculate. Using this technique, we identified one man with a reciprocal translocation and six oligochiasmatic males among 180 patients studied. The technique is easy and reliable; good-quality figures can be obtained, and meiotic studies can be carried out as often as needed.
