During the first five years of in vitro fertilisation in the University Hospital of Rotterdam, 158 pregnancies resulted in 118 deliveries of 150 babies. There were 38 clinical abortions and 2 tubal pregnancies. Transfer of multiple embryos to enhance the chance of pregnancy led to a high percentage of multiple pregnancies, 23% of all deliveries. During pregnancy the incidence of vaginal bleeding was high and the number of admissions to a hospital was increased considerably. The percentage of caesarean sections was high because of the large number of multiple pregnancies and possibly because of the 'precious' nature of the pregnancy. There was no indication of more frequent occurrence of congenital abnormalities.
在鹿特丹大学医院进行体外受精的头五年里，158次妊娠分娩出150名婴儿，共118例。有38例临床流产和2例输卵管妊娠。为提高妊娠几率而移植多个胚胎导致多胎妊娠的比例很高，占所有分娩的23%。孕期阴道出血发生率高，住院人数大幅增加。由于多胎妊娠数量众多，也可能由于妊娠的“珍贵”性质，剖宫产的比例很高。没有迹象表明先天性异常的发生率更高。
