Why isnt it viable to combine two “male” sperm cells together in an empty egg cell(ovum) to generate a viable embryo artificially?

Question

Considering that we used one 23Y and one 23X (Or two 23X) sperm cells to avoid a 46YY genotype,why wouldnt it work?

Answer 1

First, your understanding of the XY chromosome is lacking. If there is an XX egg or XY sperm that’s a generic error. It’s an X egg and an X or Y sperm.

Second, the X chromosome is much larger than the Y and contains numerous important codes. A YY embryo wouldn’t have those and would die.

Third, it wouldn’t have mitochondria. It’s a common misconception that sperm don’t have mitochondria. They do, they need them to swim, but they don’t deliver those mitochondria to the newly formed embryo. A YY embryo would also lack mitochondria.
