A specialized procedure in which an embryo is formed in the laboratory by injecting a sperm directly into the ovum is

Options

A. ICSI
B. Al
C. GIFT
D. ZIFT

Answer

To solve the question, we need to identify the specialized procedure that involves forming an embryo in the laboratory by injecting a sperm directly into an ovum. Let's break down the options provided:

1. **ICSI (Intracytoplasmic Sperm Injection)**:
- This technique involves the direct injection of a single sperm into the cytoplasm of an ovum (egg). It is specifically designed to assist in cases of male infertility where sperm quality or quantity is an issue. This method allows for fertilization to occur even when there are very few sperm available.
- Since the question specifically mentions the direct injection of sperm into the ovum, this option is a strong candidate.

2. **AI (Artificial Insemination)**:
- This procedure involves placing sperm into the female reproductive tract without directly injecting it into the ovum. It is used to treat infertility but does not involve the laboratory formation of an embryo by direct injection. Therefore, this option is incorrect.

3. **GIFT (Gamete Intra Fallopian Transfer)**:
- In this technique, both the sperm and the ovum are placed into the fallopian tubes, allowing fertilization to occur naturally. This does not involve direct injection of sperm into the ovum, making this option incorrect.

4. **JIFT (Zygote Intra Fallopian Transfer)**:
- This method involves transferring a zygote (fertilized egg) into the fallopian tube after fertilization has already occurred. It does not involve the direct injection of sperm into the ovum, so this option is also incorrect.

After analyzing all the options, we conclude that the correct answer is:

**ICSI (Intracytoplasmic Sperm Injection)**.
