title: Pregnancies from fallopian replacement of immature eggs with delayed intrauterine insemination.
abstract: Gamete intrafallopian transfer requires that a woman should not only have patent tubes but should also have had mature eggs collected for replacement. Eggs must be collected as close to ovulation as possible, to give them a good chance of fertilizing upon replacing them directly into the tubes with the spermatozoa. Preliminary results from three patients who received Fallopian replacement of immature eggs followed by delayed intrauterine insemination indicate that maturation of eggs can occur in vivo in the Fallopian tubes. Intrauterine insemination at a later time when the eggs were judged to be mature has given rise to two pregnancies from the three patients with whom this procedure was adopted.
