Spermatogenesis in Klinefelter's syndrome.
The results of a study of seminal fluid, chromosomal formula and testicular tissue performed on 32 patients with Klinefelter's syndrome are presented. The significance of the microscopic study of seminal fluid in this syndrome is well emphasized. The possible relationship of the histological pattern to spermatogenic function and chromosomal constitution is discussed. Our conclusions are that most patients were azoospermic and the the volume of the ejaculate was low or absent. The decreased density of seminal fluid was the result of the absence of spermatozoa. The seminal pH remained normal during the study. Finally, we consider that cases showing areas of spermatogenesis with spermatozoa might correspond to a gondal mosaicism we have failed to diagnose.
