The term coitus is derived from the Latin word coitio or coire, meaning "a coming together or joining together" or "to go together", and it describes a variety of sexual activities under ancient Latin names, but usually refers exclusively to penile—vaginal penetration. Lerner and Laurence Steinberg state that researchers also "rarely disclose how they define sex or even whether they resolved potential discrepancies in definitions of sex". A study by the Kinsey Institute examined the definition of sex based on a random sample of college students from 29 U. Another study by the Kinsey Institute sampled people, ranging in ages 18— Human mating strategies and Pair bond Copulation ranges from a purely reproductive activity to one of emotional bonding. For example, sexual intercourse and sexual activity in general often play a strong role in human bonding. One possible reason for this distinct biological feature may be formation of strong emotional bonds between sexual partners important for social interactions and, in the case of humans, long-term partnership rather than immediate sexual reproduction. The resulting cooperation encourages collective tasks that promote the survival of each member of the group. Copulation corresponds to a succession of innate sexual reflexes: These copulatory reflexes are controlled by hormones and facilitated by sexual pheromones. Non-primate females copulate only when in estrus ,  but sexual intercourse is possible at any time of the menstrual cycle for women. In this way, they stimulate themselves and each other, often continuing until orgasm in either or both partners is achieved. It is sometimes performed to the exclusion of all other forms of sexual activity, and may include the ingestion or absorption of semen or vaginal fluids.

Millions of sperm are present in each ejaculation, to increase the chances of one fertilizing an egg or ovum see sperm competition. When a fertile ovum from the female is present in the fallopian tubes, the male gamete joins with the ovum, resulting in fertilization and the formation of a new embryo. When a fertilized ovum reaches the uterus, it becomes implanted in the lining of the uterus the endometrium and a pregnancy begins. Artificial insemination is a form of assisted reproductive technology , which are methods used to achieve pregnancy by artificial or partially artificial means.

The study considered many Asian societies to also fall into this group, although matching data was only available from Thailand. In non-Latin, Catholic countries Poland and Lithuania are mentioned , age at sexual initiation was higher, suggesting later marriage and reciprocal valuing of male and female virginity. The same pattern of late marriage and reciprocal valuing of virginity was reflected in Singapore and Sri Lanka.
