Reproductive System
Fertilisation and Implantation
Diagram showing fertilisation
Millions of Sperm and a single egg
are released
Many sperm will swim through the womb and
up the fallopian tubes to meet
the egg…
…but only one will be able to burrow through the cell membrane and
fuse with the egg
As the nuclei of the two gametes fuse
there is a period of rapid cell division
and replication until a zygote is
formed.
