Abstract:
Sperm cytogenetic study in two patients with Klinefelter's syndrome have demonstrated that there existed a risk low but highly significant, to transmit a sex chromosome abnormality to the offsprings. This result argues for a systematic karyotype before ICSI, and if such mosaïcs can be treated by ICSI, they must be firstly associated to a genetic counselling.
