Abstract:
Untreated hydrosalpinx is known to decrease in vitro fertilization success. We report on 4 patients with hydrosalpinx for whom fresh transfers of 11 good quality embryos did not produce a pregnancy; however, frozen blastocyst transfers in natural cycles resulted in several successful pregnancies, with an implantation rate of 60% (9/15 blastocysts implanted).
