[1998 french results on medically assisted reproduction with gamete cryopreservation and donation. French Federation of CECOS].

During the year 1998, the French Federation of CECOS recorded the results of the 23 CECOS centers and IFRAERES in Toulouse. 1,573 first demands of procreation with sperm donors were registed (versus 1,620 in 1997). From 9,339 cycles (AID or IVFD), 1351 pregnancies were obtained, scoring the identical amount in terms of pregnancies as in 1997 but with less 9% in terms of cycles. Ovulation monitoring and IVFD are more and more used. The analysis of the 1,169 deliveries of the 1997 pregnancies shows a malformation rate of 1.8%. 658 male volunteers came forward as semen donors (51% more than in 1997). In gamete autocryopreservation, the number of semen preservation is globaly increasing (16% more than in 1997), mainly due to the capacity of a better reutilisation with ICSI. At the end of 1998, 15 Centres was looking after 21,222 cryopreserved embryos, 25% in the aim of a near future use.
