Erectile dysfunction (ED), also referred to as impotence, is a form of sexual dysfunction in males characterized by the persistent or recurring inability to achieve or maintain a penile erection with sufficient rigidity and duration for satisfactory sexual activity. It is the most common sexual problem in males and can cause psychological distress due to its impact on self-image and sexual relationships. Majority of ED cases are attributed to physical risk factors and predictive factors. These factors can be categorized as vascular, neurological, local penile, hormonal, and drug-induced. Notable predictors of ED include aging, cardiovascular disease, diabetes mellitus, high blood pressure, obesity, abnormal lipid levels in the blood, hypogonadism, smoking, depression, and medication use. Approximately 10% of cases are linked to psychosocial factors, encompassing conditions like depression, stress, and problems within relationships.
A cock ring or cockring is a ring worn around the penis, usually at the base. The primary purpose of wearing a cock ring is to restrict the flow of blood from the erect penis to produce a stronger erection or to maintain an erection for a longer period of time. Medically, they are sometimes used on their own, or in conjunction with a penis pump to assist in the management of erectile dysfunction. Genital adornment is another purpose, as is repositioning the genitals to provide an enhanced appearance.
Penis enlargement, or male enhancement, is any technique aimed to increase the size of a human penis. Some methods aim to increase total length, others the shaft's girth, and yet others the glans size. Techniques include surgery, supplements, ointments, patches, and physical methods like pumping, jelqing, and traction.
Panties are a form of underwear worn by women. Panties can be form-fitting or loose. Typical components include an elastic waistband, a crotch panel to cover the genitalia, and a pair of leg openings that, like the waistband, are often made of elastomer. Various materials are used, but are usually chosen to be breathable.
Gender-affirming surgery for female-to-male transgender people includes a variety of surgical procedures that alter anatomical traits to provide physical traits more comfortable to the trans man's male identity and functioning.
Boxer shorts are a type of undergarment typically worn by men. The term has been used in English since 1944 for all-around-elastic shorts, so named after the shorts worn by boxers, for whom unhindered leg movement ("footwork") is very important. Boxers come in a variety of styles and design but are characterized by their loose fit.
Boxer briefs are a hybrid type of men's undergarment which are long in the leg, similar to boxer shorts, but tight-fitting like briefs. They emerged as a style in the 1990s and are commonly worn for sports and as every-day underwear.
Radical retropubic prostatectomy is a surgical procedure in which the prostate gland is removed through an incision in the abdomen. It is most often used to treat individuals who have early prostate cancer. Radical retropubic prostatectomy can be performed under general, spinal, or epidural anesthesia and requires blood transfusion less than one-fifth of the time. Radical retropubic prostatectomy is associated with complications such as urinary incontinence and impotence, but these outcomes are related to a combination of individual patient anatomy, surgical technique, and the experience and skill of the surgeon.
Nocturnal penile tumescence (NPT) is a spontaneous erection of the penis during sleep or when waking up. Along with nocturnal clitoral tumescence, it is also known as sleep-related erection. Men without physiological erectile dysfunction or severe depression experience nocturnal penile tumescence, usually three to five times during a period of sleep, typically during rapid eye movement sleep. Nocturnal penile tumescence is believed to contribute to penile health.
In the context of gender, passing is when someone is perceived as a gender they identify as or are attempting to be seen as, rather than their biological sex. Historically, this was common among women who served in occupations where women were prohibited, such as in combat roles in the military. For transgender people, it is when the person is perceived as cisgender instead of the sex they were assigned at birth. The person may, for example, be a transgender man who is perceived as a cisgender man.
Packing is wearing padding or a phallic object in the front of the pants or underwear to give the appearance of having a penis or bulge. Packing is commonly practiced by trans men. People who cross-dress as male may also "pack".
The frenulum of the penis, often known simply as the frenulum or frenum, is a thin elastic strip of tissue on the underside of the glans and the neck of the human penis. In men who are not circumcised, it also connects the foreskin to the glans and the ventral mucosa. In adults, the frenulum is typically supple enough to allow manual movement of the foreskin over the glans and help retract the foreskin during erection. In flaccid state it tightens to narrow the foreskin opening.
A waistband is a strip of material that is either elastic or some other confining fabric that encircles the waist, usually as a component of clothing such as skirts, trousers, shorts, swimsuits, and undergarments.
A penile implant is an implanted device intended for the treatment of erectile dysfunction, Peyronie's disease, ischemic priapism, deformity and any traumatic injury of the penis, and for phalloplasty or metoidioplasty, including in gender-affirming surgery. Men also opt for penile implants for aesthetic purposes. Men's satisfaction and sexual function is influenced by discomfort over genital size which leads to seek surgical and non-surgical solutions for penis alteration. Although there are many distinct types of implants, most fall into one of two categories: malleable and inflatable transplants.
In human anatomy, the penis is an external male intromittent organ that additionally serves as the urinary duct. The main parts are the root (radix); the body (corpus); and the epithelium of the penis including the shaft skin and the foreskin (prepuce) covering the glans penis. The body of the penis is made up of three columns of tissue: two corpora cavernosa on the dorsal side and corpus spongiosum between them on the ventral side. The human male urethra passes through the prostate gland, where it is joined by the ejaculatory duct, and then through the penis. The urethra traverses the corpus spongiosum, and its opening, the meatus, lies on the tip of the glans penis. It is a passage both for urination and ejaculation of semen.
Tucking is a technique whereby an individual hides the crotch bulge of their penis and testicles so that they are not conspicuous through clothing.
An erection is a physiological phenomenon in which the penis becomes firm, engorged, and enlarged. Penile erection is the result of a complex interaction of psychological, neural, vascular, and endocrine factors, and is often associated with sexual arousal, sexual attraction or libido, although erections can also be spontaneous. The shape, angle, and direction of an erection vary considerably between humans.
The thong is a garment generally used as either underwear or in some countries, as a swimsuit. It may also be worn for traditional ceremonies or competitions.
Clitoral erection or clitoral tumescence is a physiological phenomenon where the clitoris becomes enlarged and firm.
A waist cincher is a belt worn around the waist to make the wearer's waist physically smaller, or to create the illusion of being smaller.
