Fertility and pregnancy in women with familial adenomatous polyposis

A questionnaire study was carried out among 58 Danish women with familial adenomatous polyposis concerning fertility, pregnancies, abortions and deliveries. Further data were obtained from obstetric records and general practitioners. The fertility and the course of the pregnancy of women with polyposis, frequency of miscarriages, legal abortions, mature and premature infants corresponds to the frequency among the obstetric population in Denmark. Of the 73 infants, eight (11%) were delivered by caesarean section. Of the 16 women who gave birth after an operation for familial adenomatous polyposis, 5 (31%) had a caesarean section. Of the seven infants who died, two had lethal congenital malformations and three infants were very premature.
