What is the function of the polar bodies produced during oogenesis?
"In other animals and some plants, polar bodies give rise to vital tissues that protect and nourish the embryo " ( http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3164815/). This could be the same fucntion to humans since we are all eukaryote.

Polar bodies are not waste. They sacrifice themselves after giving their energy to the embryo, completing development and differentiation into a baby.
