# Spermatozoa penetrates the zone pellucida (ZP). | |||
# Spermatozoa swims around the perivitelline space (PVS). | |||
# Spermatozoa swims around the perivitelline space (PVS). | |||
# Spermatozoa hits the first polar body (1pb). | |||
# Spermatozoa binds the oocyte membrane. | |||
# Second polar body (2pb) extrudes and the fertilization cone forms. | |||
'''Legend''' | |||
* White arrowheads - indicate the sperm | |||
* Red arrowheads - first polar body (1pb) | |||
* Yellow arrowheads - the collapsing first polar body (1pb). | |||
* White and red asterisks - mark the fertilization cone and the 2pb, respectively. | |||
