Spermatogenesis in an infertile XYY man.
Testicular histology and meiosis has been studied in an XYY male patient identified at an infertility clinic. This man was found to have an XYY set chromosome complement in 15% of spermatogonial metaphases. There was no evidence of 2 Y chromosomes at diakinesis but there appeared to be a slight excess of sperm with a fluorescent Y body.
