PROSPECTIVE FOLLOW-UP-STUDY OF 55 CHILDREN BORN AFTER SUBAZONAL INSEMINATION AND INTRACYTOPLASMIC SPERM INJECTION

In 163 couples referred for assisted fertilization, pregnancy was established by subzonal insemination (SUZI), intracytoplasmic sperm injection (ICSI) or a combination of both techniques, These couples agreed to participate in a prospective study that included a prenatal diagnosis and clinical follow-up of the children, No cytogenetic aberrations were observed in 43 children tested. In 23 pregnancies occurring after SUZI, 15 women gave birth to 21 children. After replacement of combined SUZI and ICSI embryos, 10 pregnancies resulted in 8 deliveries with 10 children. Transfer of ICSI embryos led to 130 pregnancies ending in 20 deliveries with 24 children, with many others still ongoing successfully. In total, 55 children have been examined: 29 boys and 26 girls. One child from a singleton pregnancy presented multiple congenital malformations; one twin child presented a quadriparesis. In this observational study on a limited number of children, the incidence of major malformations was not different from the incidence in the general population.
