A report on Sex organReproductive system and Penis

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

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.

- Reproductive system

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

- Penis

The reproductive organs together constitute the reproductive system.

- Sex organ

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.

- Sex organ

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.

- Reproductive system

It is a reproductive, intromittent organ that additionally serves as the urinal duct.

- Penis
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.
Male and female reproductive systems of the spotted hyena, from Schmotzer & Zimmerman, Anatomischer Anzeiger (1922). Abb. 1 (Fig. 1.) Male reproductive anatomy. Abb. 2 (Fig. 2.) Female reproductive anatomy. Principal abbreviations (from Schmotzer & Zimmerman) are: T, testis; Vd, vas deferens; BU, urethral bulb; Ur, urethra; R, rectum; P, penis; S, scrotum; O, ovary; FT, tuba Fallopii; RL, ligament uteri; Ut, uterus; CC, Corpus clitoris. Remaining abbreviations, in alphabetical order, are: AG, parotid analis; B, vesica urinaria; CG, parotid Cowperi; CP, Corpus penis; CS, corpus spongiosum; GC, glans; GP, glans penis; LA, levator ani muscle; Pr, prepuce; RC, musculus retractor clitoris; RP, Musculus retractor penis; UCG, Canalis urogenital.

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.

In most species, the clitoris lacks any reproductive function.
