The test­ tube baby programme employs which one of the following techniques?

Explanation

The "test-tube baby" program employs the technique of in vitro fertilization (IVF). In IVF, the fertilization of an egg (ovum) by sperm occurs outside the body, typically in a laboratory dish, and the resulting embryo is then transferred into the woman's uterus. This technique is used to assist individuals or couples who have difficulty conceiving naturally and is a common method of assisted reproductive technology (ART).Let's explain the provided options in more detail:a. Intra-cytoplasmic sperm injection (ICSI): ICSI is a method used within the IVF process. It involves the direct injection of a single sperm into an egg to facilitate fertilization. ICSI is particularly useful in cases of male infertility, where there may be issues with the sperm's ability to penetrate the egg. While ICSI is a component of IVF, it is not the primary technique used in "test-tube baby" programs.b. Intra-uterine insemination (IUI): IUI is a distinct procedure from IVF. It entails the placement of prepared sperm directly into a woman's uterus to increase the chances of fertilization. However, in IUI, fertilization occurs within the woman's body, not in a laboratory dish. It is typically used in cases where the sperm may need assistance in reaching the egg but is not the primary technique used in "test-tube baby" programs.c. Zygote intra-Fallopian transfer (ZIFT): ZIFT is another assisted reproductive technique similar to IVF. In ZIFT, fertilization takes place outside the body in a laboratory dish, much like in IVF. However, the key difference is that, with ZIFT, the fertilized zygote is transferred into the woman's fallopian tube instead of her uterus. ZIFT is less commonly used than standard IVF.Correct Answer: The correct answer is d. All are methods. While IVF is the primary technique used in "test-tube baby" programs, the other methods (ICSI, IUI, and ZIFT) may also be incorporated depending on the specific needs and circumstances of the individuals or couples seeking assistance with conception.Summary: The primary technique employed in "test-tube baby" programs is in vitro fertilization (IVF). ICSI, IUI, and ZIFT are complementary methods that may be used in conjunction with IVF or in specific cases of infertility. The choice of method depends on the individual's or couple's fertility issues and the recommendations of their healthcare providers.
