What is the term for sexual intercourse between a man and a woman?

The correct term for sexual intercourse between a man and a woman is "coitus." This term specifically refers to the act of sexual procreation, where the male's penis is inserted into the female's vagina, allowing for the potential of reproduction. Coitus plays a fundamental role in human reproduction and is often discussed in medical, biological, and educational contexts.

In contrast, "conception" refers to the moment when a sperm fertilizes an egg, leading to the formation of a zygote—this is a subsequent step following coitus. "Contraception" describes methods used to prevent conception from occurring, such as birth control pills, condoms, or other devices. "Gestation" is the period during which an embryo or fetus develops in the womb after conception, signifying an entirely different stage in the reproductive process. Understanding these terms is essential for grasping the overall context of human reproduction.
