title: [Characteristics of pregnancies obtained by in vitro fertilization].
abstract: 193 patients had 212 cycles induced for in vitro fertilisation between May 1983 and May 1984. 20 pregnancies of which 10 are still in progress were obtained with 6 spontaneous abortions. There were 2 so-called biochemical pregnancies and 3 extra-uterine pregnancies. The figure of 17% pregnancies where embryos were replaced totals less than 10% if one considers those pregnancies that really carry on. The number of extra-uterine pregnancies is disturbing. Finally, 2 multiple pregnancies continued, one of them being a quadruple pregnancy. The authors have made a special study to see the parameters of the conditions under which the pregnancies were obtained and the prognosis for such pregnancies.
