What controls polyspermy in mammals, the oviduct or the oocyte?
A block to polyspermy is required for successful fertilisation and embryo survival in
mammals. A higher incidence of polyspermy is observed during in vitro fertilisation (IVF) …

Membrane fusions during mammalian fertilization
BM Gadella, JP Evans - Cell Fusion in Health and Disease, 2011 - Springer
Successful completion of fertilization in mammals requires three different types of membrane
