Attitudes of Klinefelter men and their relatives towards TESE-ICSI

Purpose At the start of the implementation of TESE-ICSI for Klinefelter men in the Netherlands, we aimed to evaluate their wish to father children and their attitudes towards this artificial reproduction technique. Methods Questionnaires were distributed to members of the Dutch Klinefelter Association ( n = 365) and to Klinefelter cases known at our Department ( n = 58). Questions addressed several aspects: socio-demographic characteristics, ascertainment of diagnosis, children and child wish, and TESE-ICSI. Data were characterized using descriptive statistics. Results A total of 260 questionnaires (corresponding to 194 cases, 46%) were returned. A possible wish to father children was reported by 90% of Klinefelter men. 70% of Klinefelter men and 74% of their partners would (probably) opt for TESE-ICSI. Conclusion The majority of Dutch Klinefelter men and their partners desire to have children and have a positive attitude towards TESE-ICSI. Concerns include the risk of congenital malformations/developmental delay of the child and the limited success rate of TESE-ICSI.
