What is the name of the most common assisted reproduction procedure in which eggs are fertilized with sperm in a culture dish and then implanted into the uterus?

• A. Intracytoplasmic sperm injection
• B. Zygote intrafallopian transfer
• C. Intrauterine insemination
• D. In vitro fertilization

Answer: (D)

In vitro fertilization is the process where eggs and sperm are combined and fertilization occurs in a lab dish, with the resulting embryos then transferred into the uterus for implantation. This description matches exactly: fertilization happens outside the body in a culture dish, followed by placing the embryo into the uterus. It’s the most widely used assisted reproduction technique. Other options differ in where fertilization occurs or where the resulting embryo is placed—for example, some methods involve injecting a sperm into an egg, or transferring a fertilized cell into the fallopian tube, or inseminating into the uterus without lab fertilization.
