The reproductive system is different from other body systems in that a person has the choice not to use it to its full capacity—to procreate thus individuals can decide not to reproduce
Functions of the reproductive system
Produce hormones
Produce egg and sperm cells
Nurture the developing offspring
Transport and sustain these cells
Fertility
The capability to produce offspring
Female fertility
The possibility of getting pregnant when a sperm fertilizes a mature ovum during sexual intercourse
Male fertility
The capacity to fertilize a woman's mature egg during sexual intercourse, signified by "wet dreams" during puberty
A man remains fertile through a lifetime
Sperm can live inside the woman's body from 3 to 5 days, and an egg may be fertilized for up to 24 hours (one day) after it is released
If pregnancy does not take place, menstruation will occur in about two weeks after the egg leaves the ovary
Human sexual behavior
A broad range of behaviors in which humans display their sexuality, containing both biological elements and cultural influences and involving sexual arousal with its physiological changes
Types of sexual behavior
Solitary behavior (self-stimulation until sexual arousal to sexual climax)
Sociosexual activity (involving two or more persons heterosexually or homosexually)

There are individual differences in terms of attaining pleasure during stimulation of erogenous zones
Phases of sexual response
