Spermatozoon

When a spermatozoon meets an egg these two come together and form a larger cell that will grow into the woman's belly and become a baby.

The centrosome introduced by the spermatozoon has divided into two centrosomes, one at each pole of the nucleus.

But let us suppose [...] that one hardy or lucky spermatozoon has reached the waiting egg.

A sperm, or spermatozoa, is the microscopic male reproductive cell. Sperms are made up of oval-shaped heads and long tails that they use for mobility.
