1) Copulation

Sexual inercourse

1 of 5

2) Capacitation

Occures before fertilsation, Involves removal of choleserol and glycoproteins from membrane above acrosome making it more fluid

2 of 5

3) Acrosome reaction

Release of digestive enzymes from acrosome helping sperm digest pathway through jelly coat to oocyte, Proteins on membrane of sperm and oocyte are complemantary

3 of 5

4) Cortical reaction

Sperm membrane fuses with oocyte causing calcium ions to be released, this triggers vesicles to fuse with the oocyte membrane, Contents of granules released into space between oocyte & jelly coat forming fertilisation membrane to block more sperm

4 of 5

Mitochondria

Produces ATP that provides energy for sperm to
