methods and agents for preventing pregnancy; contraception may be physiological or artificial.

There are days of “physiological sterility” during each menstrual cycle: in a 21-day cycle these are days one and 15–21; in a 28-day cycle, days one to six and 22–28; and so on for other cycles. However, contraception based on these physiological characteristics is not entirely dependable, since the periods of ovulation may vary. Temporary sterility (inability to conceive) also occurs in many women during breast-feeding, particularly during the first postpartum months.

Artificial contraception includes the use of mechanical, chemical, biological, or surgical agents and methods or a combination of them. Contraception has a great social impact as a principal method for the prophylaxis of abortion, for family planning, and for regulation of population growth in individual countries.
