Transvaginal sperm intra-fallopian transfer (SIFT). A new treatment for unexplained infertility.

We describe a technique for the blind catheterisation of the fallopian tubes from the vagina using a specially designed device. This procedure was applied to the treatment of ten women with unexplained infertility by transvaginal sperm intrafallopian transfer, and has resulted in four normal ongoing singleton pregnancies.
