| Abstract: | Background Before ovulation, sperm-oviduct interaction mechanisms may act as checkpoint for the selection of fertilizing spermatozoa
in mammals. Postovulatory mating does not allow the sperm to attach to the oviduct, and spermatozoa may only undergo some
selection processes during the transport through the female reproductive tract and/or during the zona pellucida (ZP) binding/penetration. |
