Question

Which of the following is wrongly matched
A. IUI – Semen collected from a husband or donor is artificially introduced either into the vagina or into the uterus.
B. GIFT – Transfer of embryos with more than 8 blastomeres into the fallopian tube.
C. ICSI – Sperm directly injected into the ovum.
D. ZIFT – Transfer of embryos up to 8 blastomeres into the fallopian tube.

Answer 1

IUI stands for Intrauterine insemination. It is also called artificial insemination (AI). The term GIFT represents Gamete intrafallopian transfer. ICSI stands for intracytoplasmic sperm injection. ZIFT is Zygote intrafallopian transfer.

Complete step-by-step answer: Artificial insemination also referred to as intrauterine insemination (IUI) involves the introduction of male gametes sperm into the female’s cervix or uterine cavity. It is one of the types of in vivo fertilization where the fusion of male gamete sperm and female gamete ovum takes place within the body. Here, the semen is collected from the husband or donor and is introduced into the vagina or uterus of the female.
-Gamete intrafallopian transfer involves the removal of an ovum from a female and placing it into the fallopian tube of another female. This technique is used against infertility for females who cannot produce ovum but can provide suitable environmental conditions for fertilization.
-Intracytoplasmic sperm injection is one of the types of in vitro fertilization where the fusion of gametes takes place outside the body. In this process, the cytoplasm of the egg gets injected by a single sperm cell and avoids the acrosome reaction.
-An infertility treatment called zygote intrafallopian transfer is used when the fallopian tubes are blocked which prevents the normal binding of the sperm with the egg. Gamete intrafallopian transfer involves the transfer of ovum from one female to another female along with sperm who cannot reproduce ovum yet can get pregnant.
Hence, option B is the correct answer.

Note: Intracytoplasmic sperm injection technique is used as a treatment to overcome male infertility. The human chorionic gonadotropic hormone is injected into the female whose ovum is to be collected and then placed into another female’s fallopian tube along with sperm using laparoscopy technique.
