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 assisted reproductive technique (ART) for such couples is ZIFT, which stands for zygote intrafallopian transfer. In this technique, the sperm is collected from the donor male and the ovum is collected from the donor female. The sperm and the ovum are fused in laboratory conditions and developed till the 8-blastomere stage. This zygote or early embryo is then transferred to the fallopian tube of the mother for further development.
