Question

In MOET, a hormone is injected into a cow so as to induce follicular maturation and superovulation. This hormone has ______ like activity.

• A. progesterone
• B. testosterone
• C. estrogen
• D. FSH

Answer 1

The correct option is D FSH

Multiple Ovulation Embryo Transfer technology (MOET) involves fertilisation of multiple eggs, followed by embryo development in surrogate mother, in order to increase herd size in short time.

In the MOET technology, the female parent, a cow is administered with hormones with FSH (follicle stimulating hormone)- like activity. It stimulates follicular maturation and superovulation prodcuing 6-8 eggs per cycle instead of one.

Then the animal is either mated with a superior bull or artificially inseminated with semen collected from the superior bull. The fertilised egg at 8–32 celled stage is recovered non-surgically and transferred to surrogate mothers who later give birth to the superior offpsring. So that the genetic mother (the female used for superovulation) becomes available for another round of superovulation.

Estrogen hormones causes ovulation (releasing of eggs from ovary) in the female animals.

Progesterone hormone is required to maintain the preganancy in female animals. It maintains the endometrium (inner layer with thick blood vessels) of uterus.

Testosterone is a male hormone which helps in the development of sperm (the process called spermatogenesis) and secondary sexual characters.
So, correct answer is FSH.
