[Current program of in-vitro fertilization at the Erasmus Hospital: initial results and original ethical aspects].
The clinical results including all in vitro fertilization (IVF) cycles with oocyte pick-up in 1990 are presented. Different types of treatment including classical IVF and embryo transfer, laparoscopic replacement of zygotes in the fallopian tube (ZIFT), IVF with donor sperm (IVF-D), cross fertilization test, embryo freezing, oocyte donation and IVF with epididymal sperm were performed. The total pregnancy rate obtained reaches 38% per oocyte pick-up, 30% of clinical pregnancies (including 4 pregnancies obtained with frozen and thawed embryos). The anticipated "Take Home Baby Rate" will be around 25% per oocyte pick-up, 26 of these 40 pregnancies being today over 20 weeks of gestation. Particular ethical aspects of the program are presented: a study on couple's attitudes regarding embryo freezing as well as the final destination of possibly remaining supernumerary embryos will stress the importance of a precise clear decision on that matter before entering IVF treatment. Indeed the couple's idea on embryo destiny were very precise but also very different. The oocyte donation program has the originality of preserving the donor's anonymity by exchanging the donors recruited by the patients. It will be stressed that this kind of approach combines higher pregnancy chances for the patients, respect of ethical principles linked to gamete donation and gives satisfaction to the patients. The global normalized pregnancy cumulative curve shows that 60% of the couples entering IVF treatment will obtain a child within the first three pick-up cycles.
