Question

Which of the following statements is wrong about the test-tube baby?
(A) The embryo more than eight blastomeres are transferred into the uterus
(B) The ova and sperms used in this technique are obtained from wife and husband only
(C) The fusion of sperm and ovum is done outside the body of the female
(D) The zygote or early embryo up to eight blastomeres is transferred into the fallopian tube

Answer 1

This technique is defined as the process of successful human reproduction that results from methods other than sexual intercourse between a man and a woman and it also utilizes medical techniques that manipulate both the egg and sperm cells for successful fertilization.

Complete answer:
A test-tube baby is a baby that is conceived outside the body of the woman. The technique is commonly known as in vitro fertilization. In this technique, the fusion of sperm and ovum takes place outside the body of the female in the laboratory under proper conditions. The ova and sperms used in this technique need not be obtained from wife and husband only, it can also be obtained from the donor. An embryo is grown up to eight blastomeres stage and after that, it is transferred into the fallopian tube. This method is known as ZIFT i.e zygote intrafallopian transfer. Another way of embryo transfer is IUT i.e intrauterine transfer. In this type of technique, the embryo of more than 8 blastomeres is directly transferred into the uterus of the female.

Additional Information:
A complex series of procedures are commonly used to help with fertility or prevent genetic problems. It assists with the conception of a child which is better known as In vitro fertilization (IVF). It is performed by using the eggs of the female and her partner’s sperm or it may also involve eggs, sperm, or embryos from a known or anonymous donor depending on the situation. The mature eggs are collected from ovaries and fertilized by sperm in a lab during the IVF process. Then those eggs which are fertilized are transferred to a uterus. Generally, one full cycle of IVF takes about three to four weeks.

So, the correct answer is ‘The ova and sperms used in this technique are obtained from wife and husband only’.

Note: ART is the abbreviation for assisted reproductive techniques used to treat infertility. To treat infertility various techniques can be done where sperm and ovum are taken out from the body fertilized in the laboratory and put back on the uterus of the female. This technique is used when a female has some sort of blockage in her fallopian tube or low sperm count in the male ART is necessary.
