RESUMO
An in vitro fertilisation unit has been working since the 1 st May 1988 in the Notre-Dame Clinic in Charleroi in the Beligium province of Hainaut. This work analyses the practice and results of the first two years activity in which 185 oocytes retrievals were carried out. The account not only deals with the results (according to 8 criteria for evaluation) but also on the factors that modify these results (9 parameters). It is scientific tools that makes it possible to analyse objectively and precisely, the factors leading to success or failure in our technique. The results are compared with those in the literature and in the French national enquiries (these do not exist in Belgium) show that even in modest conditions (2 gynaecologists and a biologist who have other duties) it is possible to carry out in the first year 62 and in the second year 123 oocyte recoveries. The scrupulous attention to technical details in this university centre of reference made it possible from the beginning to achieve worthwhile results (21% pregnancies for all recoveries and 32% pregnancies for all embryo transfers).

The authors have studied a series of 2,292 pregnancies that were unselected and have calculated from this the risks of spontaneous abortion before the 28th week of the pregnancy that patients have when they come for ultrasonography for the first time in the pregnancy. They have been able to work out the risks of spontaneous abortion even when the ultrasound was normal for the time of pregnancy. The risks diminish as the pregnancy progresses and rise with the mother's age.
