Sperm is a gooey concoction used to transfer the male's reproductive cells into the female's vulva, and thereby to her eggs (the female reproductive cells). It is also the male genes that will determine the gender of a child.

One reproductive system alone does not produce a zygote. A human zygote is made from the joining of gametes (sperm and egg) from the male and female reproductive systems.

B. A human sperm cell and a human ovum are types of gametes. Gametes are reproductive cells that fuse during fertilization to form a new organism. In the case of humans, sperm cells are the male gametes and ovum (egg) cells are the female gametes.
in the female reproductive system
It's true a single sperm only has to travel a few inches, but sperm are only a thousandth of an inch themselves, so it's a long journey on their scale.
The female reproductive cell is the egg, or gamete. The female human reproductive cell is often referred to as ovum, or ova if plural.
The human ovum can remain viable for about 48 hours. And sperm about 24 hours.

Pictures of male and female reproductive organs can usually be found on sites that have to do with the physiology of the human body.
