Additionally, the results of a multidisciplinary, multicentre follow-up of the children conceived with epididymal sperm at 2 years of age are described. METHODS: This follow-up study included 378 children conceived after ICSI with epididymal sperm (percutaneous epididymal sperm aspiration: PESA group) and a control group of 1192 IVF and 1126 ICSI (with ejaculated sperm) children, all with a gestational age of 20 weeks or more. Questionnaires were sent at birth, 1 year and 4 years of age, collecting data on parental, pregnancy and child factors. A total of 148 PESA children were assessed at 2 years of age for motor performance, mental- and language development and compared with the Dutch norms. RESULTS: PESA children showed no increased risks for stillbirths, total deaths and malformations. They also did not differ from IVF and ICSI children in gender rate, birthweight and gestational age. The mental Bayley score was higher (P < 0.05) for PESA singletons and parents reported fewer (P < 0.05) behavioural problems in the PESA group than the Dutch reference group. The scores for syntactic and lexical development for the PESA singletons were better (P < 0.05) than the Dutch standards. CONCLUSIONS: ICSI with epididymal sperm does not lead to more stillbirths or congenital malformations in comparison to IVF and ICSI with ejaculated sperm and does not lead to poor development in comparison with the Dutch reference group.
