CHARACTERISTICS OF HUMAN
REPRODUCTION.

5. Reproduction is the result of physical contact between two
individuals who are attracted to one another.
Sexuality in humans is not only linked to reproduction, but
also linked to feelings and emotions necessary for
people’s psychological development.
THERE IS NOT JUST ONE WAY OF PERCEIVING
SEXUALITY. IT IS A PERSONAL DECISION.
ANY SOCIETY THAT CONSIDERS ITSELF TO BE FREE
AND DEMOCRATIC, SHOULD RESPECT DIFFERENT
SEXUAL ORIENTATIONS.

18. Fertilization takes place inside the female reproductive system after
copulation.
Every ejaculation 300-400 million sperm cells are released. Just one will
fertilize the egg cell.
Upon encountering the secondary oocyte, the acrosome of the sperm cell
produces enzymes which allow it to burrow through the outer jelly coat of
the egg. The sperm plasma then fuses with the egg’s plasma membrane,
the sperm head disconects from it flagellum and the egg travels down the
Fallopian tube to reach the uterus.
