Write the importance of MOET.


MOET – Multiple Ovulation Embryo Transfer is a method in which a cow is administered hormones with FSH (follicular stimulating hormone) like activity. These hormones induce follicular maturation and superovulation in which the cow produces 6–8 eggs per cycle instead of one egg. The cow is mated with an elite bull or artificially inseminated and the fertilized eggs at 8-32 stage is recovered non-surgically and transferred to a surrogate mother.

After a brief medical examination a healthy couple came to know that both of them are unable to produce functional gametes and should look for an ‘ART’ (Assisted Reproductive Technique). Name the ‘ART’ and the procedure involved that you can suggest to them to help them bear a child.


The ART procedure used to help the couple is ZIFT, that is, zygote intrafallopian transfer. In this method, the sperm is collected from the donor male and the ovum from donor female. The sperm and the ovum are fused in the laboratory and developed till 8-cell stage. The 8 cell zygote is then transferred into the fallopian tubes of the mother for further development.
