title: In vitro fertilization and embryo transfer program in Clamart, France.
abstract: Our in vitro fertilization and embryo transfer program really began in September 1980. Yet attempts to collect oocytes had been performed since 1978, and the first in vitro fertilizations were obtained in May 1979. The first pregnancy was obtained in April 1981, but it ended on the 12th week by a spontaneous abortion of a 45,X fetus. We have distinguished two periods in our program. The initial phase was from September 1980 until November 1982: ovulation monitoring of 365 cycles, spontaneous or stimulated, 276 laparoscopies, and 121 embryos transfers were performed, and 12 early pregnancies obtained (4.3% per laparoscopy and 9.9% per embryo transfer). Seven normal healthy infants were born (five boys and two girls); four cases were limited to biochemical pregnancies and one spontaneous abortion (yet described) was observed. The second and actual phase, December 1982-June 1983, is described more precisely: ovulation monitoring of 329 cycles, after stimulation protocols with clomiphene citrate and human menopausal gonadotropin, 230 laparoscopies, and 162 embryos transfers have been performed and have led to 34 pregnancies (14.8% per laparoscopy and 20.9% per embryo transfer). Eighteen of these 34 pregnancies are actually in progress (more than 12 weeks), 9 were limited to an increase in plasma human chorionic gonadotropin, and 7 cases ended in spontaneous abortions between 6 and 12 weeks.
