Assertion (A) : Intra cytoplasmic sperm injection (ICSI) technique is used to develop embryo in vitro.
Reason (R) : In ICSI technique, the sperm is directly injected into the ovum.
Explanation:
The given assertion states that the ICSI technique is used to develop embryos in vitro. The reason provided for this assertion is that in the ICSI technique, the sperm is directly injected into the ovum.
ICSI Technique:
ICSI is a specialized form of in vitro fertilization (IVF) technique that is used to treat male infertility. It involves the direct injection of a single sperm into the cytoplasm of an egg to achieve fertilization.
Explanation of Assertion:
The assertion is true because the ICSI technique is indeed used to develop embryos in vitro. It is a widely used assisted reproductive technology (ART) technique that is employed in cases of severe male infertility, such as low sperm count or poor sperm quality. By directly injecting a single sperm into the egg, the chances of fertilization are significantly increased, allowing for the development of embryos in a controlled laboratory setting.
Explanation of Reason:
The reason provided for the assertion is also true. In the ICSI technique, a highly skilled embryologist uses a micromanipulation system to immobilize a single sperm and inject it directly into the cytoplasm of the egg. This ensures that fertilization occurs even in cases where natural sperm-egg interaction is impaired.
Relationship between Assertion and Reason:
Both the assertion and the reason are true. However, the reason provided does not directly explain why the ICSI technique is used to develop embryos in vitro. It only describes the technical details of the procedure. Therefore, the correct choice is option A - "Both assertion (A) and reason (R) are true but reason (R) is not the correct explanation of assertion (A)."
In conclusion, the ICSI technique is indeed used to develop embryos in vitro, and in this technique, the sperm is directly injected into the ovum. However, the reason provided does not fully explain why the ICSI technique is used, making option A the correct choice.
