Abstract
Like XO [male][male], [male][male] carrying the incomplete Y chromosome designated Y" are sterile. Spermatozoa from such [male][male] appear to be normal morphologically but do not become motile. The failure of sperm to function cannot be the result of the genetic constitution of the sperm nuclei. In an attempt to determine the nature of sterility in this case, the authors transplanted testes from XY" [male][male] to normal [male][male]- Sperms from the implant never functioned. In reciprocal transplants, testes from normal [male][male], grown in XY" [male][male], sperms from the implant were normal, but those from the host failed to function. "The sterility is either caused by early somatic influences on the developing gametes or is an autonomous gametic property due to predetermination in the diploid phase.".
