In vitro fertilization at the Leiden Academic Hospital. Initial experiences.
At the Leiden University Hospital the first IVF treatment was initiated November 1st, 1985. In the following year 139 cycles with ovarian stimulation have been started with 75 patients. Thirty percent of these stimulations have been cancelled before oocyte retrieval due to suboptimal response. Totally 97 pick-ups have been carried out on 65 patients resulting in 78 embryo transfers to 54 patients. Fourteen clinical pregnancies were obtained. Four ended with a first trimester abortion, one was a tubal pregnancy and 9 are ongoing or have been already delivered.
