The correct Answer is:
To solve the question, we need to identify the correct term for the procedure where an embryo is formed in the laboratory by injecting a sperm directly into the ovum. Let's analyze the options provided: 1. **ICSI (Intracytoplasmic Sperm Injection)**: This is a specialized procedure where a single sperm is injected directly into the cytoplasm of an egg (ovum). This method is commonly used in cases of male infertility. 2. **AI (Artificial Insemination)**: This procedure involves introducing semen into the female reproductive tract, but it does not involve directly injecting sperm into the ovum. Therefore, it does not fit the description given in the question. 3. **GIFT (Gamete Intrafallopian Transfer)**: In this procedure, both sperm and eggs are placed into the fallopian tubes, where fertilization occurs naturally. This does not involve direct injection into the ovum. 4. **ZIFT (Zygote Intrafallopian Transfer)**: This method involves transferring a zygote (fertilized egg) into the fallopian tube after fertilization has occurred in the lab. It does not involve direct injection of sperm into the ovum. Based on the definitions and descriptions of each procedure, the correct answer to the question is: **ICSI (Intracytoplasmic Sperm Injection)**. ### Step-by-Step Solution: 1. **Identify the procedure needed**: The question asks for a procedure that involves injecting sperm directly into the ovum to form an embryo in the lab. 2. **Analyze each option**: - **ICSI**: Direct injection of sperm into the ovum. Matches the description. - **AI**: Involves introducing semen into the reproductive tract, not direct injection into the ovum. - **GIFT**: Transfers gametes to the fallopian tube for natural fertilization, not direct injection. - **ZIFT**: Transfers a zygote to the fallopian tube, not direct injection of sperm. 3. **Select the correct option**: Since ICSI is the only procedure that matches the description given in the question, it is the correct answer. ### Final Answer: **ICSI (Intracytoplasmic Sperm Injection)**.
