Which fertility assistance program inserts oocytes and sperm into the fallopian tube?

• A. GIFT
• B. IVF
• C. ICSI
• D. ZIFT

Answer: (A)

Gamete Intrafallopian Transfer places oocytes and sperm directly into the fallopian tube, so fertilization occurs there rather than in a lab. This method is distinct from the others: in vitro fertilization fertilizes eggs outside the body and then transfers the resulting embryo into the uterus; intracytoplasmic sperm injection is a lab technique used with IVF where a single sperm is injected into an oocyte to achieve fertilization; and zygote intrafallopian transfer places a fertilized zygote into the fallopian tube.
