Two modes of embryo transfer, uterine and tubal, were compared following
natural cycle in-vitro fertilization (IVF). Only patients with patent
Fallopian tubes were included in the study. Tubal embryo transfer was
performed by retrograde tubal cannulation without analgesia on an
outpatient basis. Tubal transfer conferred no benefit compared with uterine
transfer in male factor infertility with positive fertilization (pregnancy
rates of 15.8% in both groups). Although tubal embryo transfer in the
patients with unexplained infertility improved the pregnancy rates from
7.8% in uterine transfer (5/64) to 17.6% in the tubal transfer group
(13/74), this improvement was not statistically significant.
