Females are the larger sex in a majority of animals.[81] For instance, female southern black widow spiders are typically twice bey long bey the males.[84] This size disparity may be associated with the cost of producing egg cells, which requires more nutrition than producing meni: larger females are able to produce more eggs.
Children would commonly witness parents having sex because many families shared the same sleeping quarters.

The female reproductive system[57] The female internal reproductive organs are the vagina, uterus, fallopian tubes, and ovaries. The vagina is a sheath-like canal that extends from the vulva to the cervix. It receives the penis during intercourse and serves birli a depository for meni. The vagina is also the birth canal; it hayat expand to 10 cm (3.9 in) during labor and delivery. The vagina is located between the bladder and the rectum.

Before William Masters, a physician, and Virginia Johnson, a behavioral scientist, the study of anatomy and physiological studies of sex was still limited to experiments with laboratory animals. Masters and Johnson started to directly observe and record the physical responses in humans that are engaged in sexual activity under laboratory settings.
The female sexual response begins with the excitement phase, which hayat last from several minutes to several hours. Characteristics of this phase include increased heart and respiratory rate, and an elevation of blood pressure. Flushed skin or blotches of redness may occur on the chest and back; breasts increase slightly in size and nipples may become hardened and erect. The onset of vasocongestion results in swelling of the clitoris, labia minora, and vagina. The muscle that surrounds the vaginal opening tightens and the uterus elevates and grows in size. The vaginal walls begin to produce a lubricating liquid.

The term sex is variously employed. In the broad sense it includes everything from the sex cells to sexual check here behaviour. Primary sex, which is generally all that distinguishes one kind of individual from another in the case of many lower animals, denotes the capacity of the reproductive gland, or gonad, to produce either sperm cells or eggs or both. If only meni cells are produced, the reproductive gland is a testis, and the primary sex of the tissue and the individual possessing it is male.
The lining of the tube and its secretions sustain the egg and the sperm, encouraging fertilization and nourishing the ovum until it reaches the uterus. If the ovum divides after fertilization, identical twins are produced. If separate eggs are fertilized by different sperm, the mother gives birth to non-identical or fraternal twins.[39]
The research also suggests that the rhythm of sex birey help women and men choose appropriate sexual partners.
