A report on Sex organ and Penis

The sex organs of a green algae Chara are the male antheridia (red) and female archegonia (brown).

Females have corkscrew vaginas with many blind pockets designed for difficult penetration and to prevent becoming pregnant. This reduced the likelihood of fertilization by unwanted aggressors in favor of fitter mates.

A penis (plural penises or penes ) is the primary sexual organ that male animals use to inseminate females (or hermaphrodites) during copulation.

- Penis

The Latin term genitalia, sometimes anglicized as genitals, is used to describe the externally visible sex organs: in male mammals, the penis and scrotum; and in female mammals, the vulva and its organs.

The sex organs of a green algae Chara are the male antheridia (red) and female archegonia (brown).

The clitoral hood has a normal anatomical variation in size and appearance in different adult women: while it is completely covered by the labia majora in some women, standing with their legs closed, in others it is pronounced and clearly visible.

With a urogenital system in which the female urinates, mates and gives birth via an enlarged, erectile clitoris, female spotted hyenas are the only female mammals devoid of an external vaginal opening.

The clitoris ( or ) is a female sex organ present in mammals, ostriches and a limited number of other animals.

Unlike the penis, the male homologue (equivalent) to the clitoris, it usually does not contain the distal portion (or opening) of the urethra and is therefore not used for urination.

The reproductive system of an organism, also known as the genital system, is the biological system made up of all the anatomical organs involved in sexual reproduction.

The final category are those used for copulation, and deposition of the spermatozoa (sperm) within the male, these include the penis, urethra, vas deferens, and Cowper's gland.

The length of the labia minora varies significantly between women: while the labia majora completely enclose the labia minora in some women (top row), in other women they protrude and are clearly visible in upright standing position (bottom row). Colloquially, these variations of the labia are also referred to as "innies" and "outies".

The vulva (plural: vulvas or vulvae; derived from Latin for wrapper or covering) consists of the external female sex organs.

The clitoris is the homologue of the penis, and the clitoral hood is the female equivalent of the male foreskin, and may be partially or completely hidden within the pudendal cleft.

The scrotum or scrotal sac is an anatomical male reproductive structure located at the base of the penis that consists of a suspended dual-chambered sac of skin and smooth muscle.

Male sex hormones are secreted by the testes later in embryonic life to cause the development of secondary sex organs.
