Scrotum in the context of Epididymis

Pubic hair (or pubes /ˈpjuːbiːz/, /pjuːbz/) is terminal body hair that is found in the genital area and pubic region of adolescent and adult humans. The hair is located on and around the sex organs, and sometimes at the top of the inside of the thighs, even extending down the perineum, and to the anal region. Pubic hair is also found on the scrotum and base of the penile shaft (in males) and on the vulva (in females). Around the pubis bone and the mons pubis that covers it, it is known as a pubic patch, which can be styled.

Although fine vellus hair is present in the area during childhood, pubic hair is considered to be the heavier, longer, coarser hair that develops during puberty as an effect of rising levels of hormones: androgens in males and estrogens in females.

The male reproductive system consists of a number of sex organs that play a role in the process of human reproduction. These organs are located on the outside of the body, and within the pelvis.

The main male sex organs are the penis and the scrotum, which contains the testicles that produce semen and sperm, which, as part of sexual intercourse, fertilize an ovum in the female's body; the fertilized ovum (zygote) develops into a fetus, which is later born as an infant. The corresponding system in females is the female reproductive system.

In humans, the anus (pl.: anuses or ani; from Latin ānus, "ring", "circle") is the external opening of the rectum located inside the intergluteal cleft. Two sphincters control the exit of feces from the body during an act of defecation, which is the primary function of the anus. These are the internal anal sphincter and the external anal sphincter, which are circular muscles that normally maintain constriction of the orifice and which relax as required by normal physiological functioning. The inner sphincter is involuntary and the outer is voluntary. Above the anus is the perineum, which is also located beneath the vulva or scrotum.

In part owing to its exposure to feces, a number of medical conditions may affect the anus, such as hemorrhoids. The anus is the site of potential infections and other conditions, including cancer (see anal cancer).

A vibrator, sometimes described as a massager, is a sex toy that is used on the body to produce pleasurable sexual stimulation. There are many different shapes and models of vibrators. Most modern vibrators contain an electric-powered device that pulsates or throbs. Vibrators can be used for both solo play and partnered play by one or more people. Devices exist to be used by couples to stimulate the genitals of both partners. They can be applied to erogenous zones – such as the vulva, vagina, penis, scrotum, anus, or rectum – for sexual stimulation, for the release of sexual frustration, and to achieve orgasm. Vibrators may be recommended by sex therapists for women who have difficulty reaching orgasm through masturbation or intercourse.

Fellatio (also known as fellation, and in slang as blowjob, BJ, giving head, or sucking off) is an oral sex act consisting of the stimulation of a penis by using the mouth. Oral stimulation of the scrotum may also be termed fellatio, or colloquially as teabagging.

It may be performed by a sexual partner as foreplay before other sexual activities, such as vaginal or anal intercourse, or as an erotic and physically intimate act of its own. Fellatio creates a risk of contracting sexually transmitted infections (STIs), but the risk is significantly lower than that of vaginal or anal sex, especially for HIV transmission.

Genital piercing is a form of body piercing that involves piercing a part of the genitalia, thus creating a suitable place for wearing different types of jewellery. Nevertheless, the term may also be used pars pro toto to indicate all body piercings in the area of the anus, perineum, penis, scrotum, and vulva, including piercings such as anal, guiche, and pubic that do not involve perforation of genitalia. Genital piercings can be done regardless of sex, with various forms of piercings available. The main motive is beautification and individualization; in addition, some piercings enhance sexual pleasure by increasing stimulation. Pre-modern genital piercings is most culturally widespread in Southeast Asia, where it has been part of traditional practice since ancient times. Records of genital piercing are found in the Kama Sutra.

The perineum (pl.: perineums or perinea) in placental mammals is the space between the anus and the genitals. The human perineum is between the anus and scrotum in the male or between the anus and vulva in the female. The perineum is the region of the body between the pubic symphysis (pubic arch) and the coccyx (tail bone), including the perineal body and surrounding structures. The perineal raphe is visible and pronounced to varying degrees.

The perineum is frequently perceived as an erogenous zone, with touch in that area being perceived as both erogenous and aversive by different individuals.

Musk is a class of aromatic substances commonly used as base notes in perfumery. They include glandular secretions from animals such as the musk deer, numerous plants emitting similar fragrances, and artificial substances with similar odors. Musk was a name originally given to a substance with a strong odor obtained from a gland of the musk deer. The substance has been used as a popular perfume fixative since ancient times and is one of the most expensive animal products in the world. The name originates from the Late Greek μόσχος 'moskhos', from Persian mushk and Sanskrit मुष्क muṣka (lit. 'testicle') derived from Proto-Indo-European noun múh₂s meaning "mouse". The deer gland was thought to resemble a scrotum. The term is applied to various plants and animals of similar smell (e.g., muskox) and has come to encompass a wide variety of aromatic substances with similar odors, despite their often differing chemical structures and molecular shapes.

Natural musk was used extensively in perfumery until the late 19th century when economic and ethical motives led to the adoption of synthetic musk, which is now used almost exclusively. The organic compound primarily responsible for the characteristic odor of musk is muscone. There are several ways of preparing the commercial musk, and the best method is to dry the pod by sunning and airing immediately after it is taken from the animal. Natural musk is usually packed in hermetically-sealed vessels and wooden boxes lined with tin foil because of its powerful diffusion of odor.

Groping is a type of sexual assault involving the intentional inappropriate touching of another person commonly without their consent. The term generally has a negative connotation in many societies. Touching a consenting person's body during sexual activity, a massage, or a medical examination is not usually considered groping, though the term is sometimes used to include clumsy, selfish, or inappropriate sexual touching. Areas of the body most frequently groped include the buttocks, breasts, vulva, thigh, penis, and scrotum. Gropers might use their hands, but pressing any part of their body against another person can be considered groping.

The practice of women being subjected to a pat down by officers, such as customs or security officers at airports, is controversial. Such behaviour by public officials requires a clear legal authorization.

In human male anatomy, the radix (/reɪ.dɪks/) or root of the penis is the internal and most proximal portion of the human penis that lies in the perineum. Unlike the pendulous body of the penis, which is suspended from the pubic symphysis, the root is attached to the pubic arch of the pelvis and is not visible externally. It is triradiate in form, consisting of three masses of erectile tissue; the two diverging crura, one on either side, and the median bulb of the penis or urethral bulb. Approximately one third to one half of the penis is embedded in the pelvis and can be felt through the scrotum and in the perineum.

Emasculation is the removal of the external male sex organs, which includes both the penis and the scrotum, the latter of which contains the testicles. It is distinct from castration, where only the testicles are removed. Although the terms are sometimes used interchangeably, the potential medical consequences of emasculation are more extensive due to the complications arising from the removal of the penis. There are a range of religious, cultural, punitive, and personal reasons why someone may choose to emasculate themselves or another person.

The term emasculation may be used in a metaphorical sense, referring to the perceived loss of attributes traditionally associated with masculinity, such as strength, power, or autonomy.

A handjob (also spelled hand job) is a manual sex act involving a person stimulating the penis or scrotum of another by using the hand. This is done to induce an erection for sexual pleasure, sexual arousal and may result in orgasm and ejaculation.

A handjob can be performed as either foreplay or as non-penetrative sex. It is analogous to fingering (manual stimulation of the vulva or vagina).Someone may give a handjob so as not to engage in penetrative sexual activity. Besides avoiding the risks associated with sexual penetration, such as sexually transmitted infections (STIs) or pregnancy from penile-vaginal sex, some people engage in non-penetrative sex to preserve virginity.

Testicular cancer is cancer that develops in the testicles, a part of the male reproductive system. Symptoms may include a lump in the testicle or swelling or pain in the scrotum. Treatment may result in infertility.

Risk factors include an undescended testis, family history of the disease, and previous history of testicular cancer. More than 95% are germ cell tumors which are divided into seminomas and non-seminomas. Other types include sex-cord stromal tumors and lymphomas. Diagnosis is typically based on a physical exam, ultrasound, and blood tests. Surgical removal of the testicle with examination under a microscope is then done to determine the type.

Testicular torsion occurs when the spermatic cord (from which the testicle is suspended) twists, cutting off the blood supply to the testicle. The most common symptom in children is sudden, severe testicular pain. The testicle may be higher than usual in the scrotum, and vomiting may occur. In newborns, pain is often absent; instead, the scrotum may become discolored or the testicle may disappear from its usual place.

Most of those affected have no obvious prior underlying health problems. Testicular tumor or prior trauma may increase risk. Other risk factors include a congenital malformation known as a "bell-clapper deformity" wherein the testis is inadequately attached to the scrotum allowing it to move more freely and thus potentially twist. Cold temperatures may also be a risk factor. The diagnosis should usually be made based on the presenting symptoms but requires timely diagnosis and treatment to avoid testicular loss. An ultrasound can be useful when the diagnosis is unclear.

In primates, and specifically in humans, the labia majora (sg.: labium majus), also known as the outer lips or outer labia, are two prominent longitudinal skin folds that extend downward and backward from the mons pubis to the perineum. Together with the labia minora, they form the labia of the vulva.

The labia majora are homologous to the male scrotum.

Teabagging is a slang term for the sexual act involving placing the scrotum into the mouth of a sexual partner for sexual pleasure, or onto the face or head of another person, sometimes as a comedic device.

The name of the practice, when it is done in a repeated in-and-out motion, is derived from its passing resemblance to the dipping of a tea bag into a cup of hot water as a method of brewing tea. As a form of non-penetrative sex, it can be done for its own enjoyment or as foreplay.

The urogenital triangle is the anterior part of the perineum. In female mammals, it contains the vulva, while in male mammals, it contains the penis and scrotum.

The internal pudendal veins (internal pudic veins) are a set of veins in the pelvis. They are the venae comitantes of the internal pudendal artery. Internal pudendal veins are enclosed by pudendal canal, with internal pudendal artery and pudendal nerve.

They begin in the deep veins of the scrotum and of the penis, issuing from the bulb of the vestibule and the bulb of the penis, respectively. They accompany the internal pudendal artery, and unite to form a single vessel, which ends in the internal iliac vein.
