Question

In which of the following ARTs, does in vivo fertilisation occur?
(a) ZIFT
(b) GIFT
(c) ICSI
(d) IVF

Answer 1

Answer:

IVF

is the correct answer

Answer 2

The procedure known as In vivo fertilizations occurs in ART called as (b) GIFT.

Assisted Reproductive Technology (ART):

The condition in which the married couple fail to reproduce despite of normal coitus, it is called as infertility.

To assist such couples, medical field is using unique technology called assisted reproductive technology (ART).

ART involves procedures associated with treating the infertility and gives main attention to the following process:

1. Surgical removal of egg from ovaries
2. Uniting sperm and egg under lab conditions.
3. Inserting the formed embryo into the uterus.

The following are the list of ARTs used in the treatment of infertility:

• Zygote intra fallopian transfer (ZIFT)
• Gamete intrafallopian transfer (GIFT)
• Intracytoplasmic Sperm Injection (ICSI)
• In vitro fertilization (IVF)

In vivo fertilization:

When the process of fertilization (fusion of male and female gamete) occurs in the fallopian tube of the female reproductive system, it is called as In vivo fertilization.

Option (b) GIFT is correct

• GIFT is elaborately called as Gamete intrafallopian transfer. From the name itself it is clear that, here the gametes such as egg and sperm are involved.
• There may be condition where the female is infertile but her fallopian tube can support pregnancy.
• In such case, the eggs from the donor's ovaries is collected and it is injected along with the male sperm with the help of catheter into the the fallopian tube of the infertile female.
• After the completion of this procedure, the process of fertilization occurs inside the body.
• Thus, it is inferred that, In vivo fertilization occurs in procedure called as GIFT.

Option (a), (c) and (d) are incorrect

• In procedures such as ZIFT, ICSI, and IVF fertilization occurs under laboratory condition. That is it is invitro fertilization.
• Thus, except option (b) all the other are incorrect.
