title: Zygote intrafallopian transfer as a successful treatment for unexplained infertility.
abstract: This study describes the zygote intrafallopian transfer treatment in patients with unexplained infertility. After retrieval, the oocytes were inseminated with 80,000 progressive motile sperm cells per milliliter. If fertilization occurred, a maximum of three zygotes were replaced by laparoscopy in the fimbrial end of one healthy fallopian tube. A pregnancy rate of 48.1% per zygote intrafallopian transfer replacement was obtained. Seventeen pregnancies are actually ongoing, two patients delivered, and seven patients miscarried. Even after replacing a maximum of three zygotes, there were 6 twin and 2 triplet pregnancies.
