Question

Select the correct option:
i) In IUT, embryos with more than 8 blastomeres are transferred into the uterus.
ii) In ZIFT, a fertilised egg is transferred directly into the fallopian tube.
iii) In GIFT, ovum is transferred directly into the fallopian tube.

• A. Statement i and ii are incorrect
• B. Only statement i is correct
• C. All statements are correct
• D. Statement ii and iii are incorrect

Answer 1

The correct option is C All statements are correct

In IVF (in vitro fertilisation) followed by ET (embryo transfer), also called test tube baby programme, ova from the female and sperm from male are collected and induced to form zygote in the laboratory.

The zygote (fertilised egg) or early embryos (with upto 8 blastomeres) could be transferred into the fallopian tube. This is termed as zygote intra fallopian transfer (ZIFT).

The embryos with more than 8 blastomeres are transferred into the uterus and this is called intra uterine transfer (IUT).

Gamete intra fallopian transfer (GIFT) is a technique in which the ovum is transferred into the fallopian tube of women who are unable to produce the ovum.

So, all the given statements are correct.
