Cortical granules
The sperm
binds to
the plasma
membrane of
the cocyte.
Sperm undergo
capacitation as
they migrate
to the cocyte
Additional
sperm cells
are rejected.
The acrosomal
reaction
releases
enzymes from
the head of
the sperm
The sperm nucleus
wells to form a male
pronucleus. The cocyte
completes meiosis il
and the ovurn's nucleus
swells to form a female
pronucleus
