The purpose of this report is to assess the impact of fetal surgery on futu
re maternal fertility, subsequent pregnancy outcome, and the incidence of p
regnancy complications. Retrospective data were collected on 70 mothers who
underwent fetal surgery between April 1981 and June 1996. Indications for
open hysterotomy fetal surgery included congenital diaphragmatic hernia (n
= 44), congenital cystic adenomatoid malformation of the lung (n = 11), uri
nary obstruction (n = 9), sacrococcygeal teratoma (n = 4), heart block (n =
1), and acardiac-acephalic twin reduction (n = 1). The following data were
obtained: number of pregnancy attempts, number of successful pregnancies,
pregnancy outcome including obstetrical and neonatal complications, and inf
ertility after fetal surgery. There were 45 respondents, of whom 35 attempt
ed subsequent pregnancies. Thirty-two were successful, resulting in 31 live
births. Two women had a strong prefetal surgery history of infertility, 1 h
as only attempted to conceive for 3 months. We report this experience becau
se the effect of open fetal surgery on future fertility is such an importan
t question for our patients and referring physicians. This analysis suggest
s that hysterotomy and open fetal surgery has a negligible impact on matern
al fertility.
