How do spermatozoa activate oocytes?

B Dale, M Wilding, GF Coppola, E Tosti - Reproductive biomedicine online, 2010 - Elsevier
Although the spermatozoon is 500,000 times smaller in volume than the oocyte, it induces
rapid and dramatic changes in oocyte physiology that lead to meiosis re-initiation. These …
