Reduced pregnancy outcome in patients with unilateral or bilateral hydrosalpinx after in vitro fertilization.

In a retrospective study, we compared 118 patients with hydrosalpinx and 157 patients with bilateral salpingectomy entering an established in vitro fertilisation programme between 1988 and 1992. Patients with unilateral or bilateral hydrosalpinx had a lower clinical pregnancy rate, a higher miscarriage rate, and a lower ongoing pregnancy rate than patients with absent Fallopian tubes.
