Abstract
The second report of the ESHRE Task Force on ICSI describes the outcome of 13,666 ICSI cycles carried out in 1994 by 90 centres in 24 countries. Most cycles used ejaculated spermatozoa (94.4%) while epididymal and testicular spermatozoa were used in 4.1% and 1.5% of the cycles. Outcome measures in the three types of spermatozoa included the number of: (i) intact oocytes after ICSI; (ii) normally fertilized oocytes; (iii) transferred and frozen embryos; (iv) embryo transfers and (v) cycles with positive serum HCG. The evolution of the pregnancies was analysed in terms of pregnancy losses and clinical pregnancies. The results of ICSI with spermatozoa from the ejaculate was analysed according to the year that ICSI started in the different centres. The survey also reports the follow-up of children born after ICSI carried out until 31 December 1993. A total of 455 pre- and postnatal karyotypes revealed the presence of nine abnormal karyotypes. Twenty-four centres reported on 807 ICSI children: 763 using ejaculated spermatozoa, 36 using epididymal spermatozoa and eight using testicular spermatozoa. Sixteen major congenital malformations were reported.
