title: [In vitro fertilization. Analysis of results after the first 2 years' activity].
abstract: 413 menstrual cycles were monitored in the first two years of the work of the In-Vitro Fertilization Unit in La Pitié-Salpêtrière. On-going pregnancies were achieved from the very first months of activity, with a level which stayed relatively constant in the first year. Technical changes were introduced and in particular a higher recovery rate of oocytes when ultrasound was used and above all when LH-RH analogues were used in the process of stimulation. It is this last point that seems to be the most interesting. In fact, when the results are examined there is a definite rise in the number of on-going pregnancies of which the level went up by 2.3 times as compared with using a classical protocol of Clomithene citrate and HMG. In the 153 cycles when D-Trp6 LH-RH was used, the percentage of on-going pregnancies was 13.7% for each cycle and 20% for embryo implants. Furthermore, it became possible to work out the dates for the patients and this appears to us essential as the numbers of couples attending increase.
