The laparoscope in follicular oocyte collection and gamete intrafallopian transfer and fertilization (GIFT)

Laparoscopic recovery of bovine follicular oocytes was studied. The collection of oocytes from the superovulated bovine ovary was maximized by standardizing the collection technique. The technique was highly successful, with a 79% oocyte recovery rate of the follicles aspirated. Collected oocytes were transferred to the inseminated recipient's oviduct with a minimum of trauma through the laparoscope. This gamete intrafallopian transfer and fertilization (GIFT) resulted in multiple embryo recovery in the cow. Oviductal catheterization and the potential of GIFT are described and discussed.
