Sex organ

This is an article about Human Anatomy

A sex organ, or primary sexual characteristic, narrowly defined, is any of those anatomical parts of the body (which are not always bodily organs according to the strict definition) which are involved in sexual reproduction and constitute the reproductive system in a complex organism; namely: Sex organ (Look up Sex organ in Wikipedia or Wikitionary)

Male penis (Look up penis in Wikipedia or Wikitionary) The penis (plural penises, penes) is an external male sexual organ. The penis is the male reproductive organ and for mammals additionally serves as the external male organ of urination. glans penis (Look up glans penis in Wikipedia or Wikitionary)) The glans penis is the sensitive erectile head of the penis. It is also commonly referred to as the head of the penis, mushroom tip, fireman's helmet, or bell end (coarse slang), although this is not the proper medical terminology. It is wholly or partially covered by the foreskin, except when the foreskin is retracted, such as during sexual intercourse or masturbation while the penis is erect, or when the foreskin has been removed by circumcision. prepuce (Look up prepuce in Wikipedia or Wikitionary) The prepuce is a retractable piece of skin which covers part of the genitals of primates and other mammals - also known as foreskin testicle (Look up testicle in Wikipedia or Wikitionary) the male sex gland that produces sperm and male hormones, found in some types of animals scrotum (Look up scrotum in Wikipedia or Wikitionary) The bag of skin and muscle that contains the testicles in mammals. prostate (Look up prostate in Wikipedia or Wikitionary) A gland in male mammals surrounding the urethra just below the urinary bladder that controls the release of urine from the bladder and produces a secretion that is the fluid part of semen. seminal vesicle (Look up seminal vesicle in Wikipedia or Wikitionary)s, They secrete a significant proportion of the fluid that ultimately becomes semen. About 70% of the seminal fluid in humans originates from the seminal vesicles. epididymis (Look up epididymis in Wikipedia or Wikitionary) A narrow, tightly-coiled tube connecting the vas efferens from the rear of each testicle to its vas deferens, which sperm are stored during maturation. Cowper's gland (Look up Cowper's gland in Wikipedia or Wikitionary)s One of two small exocrine glands present in the reproductive system of human males. They are homologous to Bartholin's glands in females.

Female vulva (Look up vulva in Wikipedia or Wikitionary) The external female sexual organs, collectively. clitoris (Look up clitoris in Wikipedia or Wikitionary)), A small elongated erectile organ at the anterior part of the vulva in female mammals, homologous with the penis. (Klit in Greek means "key") labia (Look up labia in Wikipedia or Wikitionary) The folds of tissue at the opening of the vulva, Labia majora and Labia Minora vagina (Look up vagina in Wikipedia or Wikitionary) The passage leading from the opening of the vulva to the cervix of the uterus in female mammals. cervix (Look up cervix in Wikipedia or Wikitionary) the lower, narrow portion of the uterus where it joins with the top end of the vagina. uterus (Look up uterus in [[Wikipedia:uterus|Wikipedia]] or [[Wikt:uterus|Wikitionary]]) Either of the two ducts in female mammals through which ova pass from the ovaries to the uterus. Fallopian tube (Look up Fallopian tube in Wikipedia or Wikitionary) Either of the two ducts in female mammals through which ova pass from the ovaries to the uterus. ovary (Look up ovary in Wikipedia or Wikitionary) A female reproductive organ, often paired, that produces ova and in mammals secretes the hormones estrogen and progesterone. Skene's gland (Look up Skene's gland in Wikipedia or Wikitionary) The Skene's glands (also known as the lesser vestibular, periurethral glands, or paraurethral glands) are glands located on the upper wall of the vagina, around the lower end of the urethra. They drain into the urethra and near the urethral opening. The location of the Skene's glands is also known as the Gräfenberg spot or G-spot; the general area is the urethral sponge. Bartholin's gland (Look up Bartholin's gland in Wikipedia or Wikitionary)s. Two glands located slightly below and to the left and right of the opening of the vagina in women. They produce a waxy secretion which is sometimes described as being a lubrication for sexual congress.

The Latin term genitalia (sometimes anglicized as genitals) is used to describe the sex organs, and in the English language this term and genital area are most often used to describe the externally visible sex organs, known as primary genitalia or external genitalia: in males the penis and scrotum, in females the vulva.

The other sex organs are called the secondary genitalia or internal genitalia. An even wider notion, subjective but always prominently including the genitalia, is erogenous zones.

Gonad(s) is a sex organ that produces gamete(s), specifically the testis^ or ovary^ in humans.

Organs of sexual anatomy originate from a common anlage^ and differentiate into male or female sex organs. The SRY^ gene^, usually located on the Y chromosome* and encoding the testis determining factor^, decides the direction of this differentiation. Each sexual organ in one sex has a homology (biology)^ counterpart in the other one. See a list of homologues of the human reproductive system^.
