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.
Sildenafil, sold under the brand name Viagra, among others, is a medication used to treat erectile dysfunction and pulmonary arterial hypertension. It is also sometimes used off-label for the treatment of certain symptoms in secondary Raynaud's phenomenon. It is unclear if it is effective for treating sexual dysfunction in females. It can be taken orally, intravenously, or through the sublingual route. Onset when taken orally is typically within twenty minutes and lasts for about two hours.
Peyronie's disease is a connective tissue disorder involving the growth of fibrous plaques in the soft tissue of the penis. Specifically, scar tissue forms in the tunica albuginea, the thick sheath of tissue surrounding the corpora cavernosa, causing pain, abnormal curvature, erectile dysfunction, indentation, loss of girth and shortening.
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 and foreskin size. Techniques include surgery, supplements, ointments, patches, and physical methods like pumping, jelqing, and traction.
Vaginismus is a condition in which involuntary muscle spasm interferes with vaginal intercourse or other penetration of the vagina. This often results in pain with attempts at sex. Often it begins when vaginal intercourse is first attempted. Vaginismus may be considered an older term for pelvic floor dysfunction.
Sexual dysfunction is difficulty experienced by an individual or partners during any stage of normal sexual activity, including physical pleasure, desire, preference, arousal, or orgasm. The World Health Organization defines sexual dysfunction as a "person's inability to participate in a sexual relationship as they would wish". This definition is broad and is subject to many interpretations. A diagnosis of sexual dysfunction under the DSM-5 requires a person to feel extreme distress and interpersonal strain for a minimum of six months. Sexual dysfunction can have a profound impact on an individual's perceived quality of sexual life. The term sexual disorder may not only refer to physical sexual dysfunction, but to paraphilias as well; this is sometimes termed disorder of sexual preference.
Vardenafil, sold under the brand name Levitra among others, is a medication that is used for treating erectile dysfunction. It is a PDE5 inhibitor. It is taken by mouth.
Sexual arousal disorder is characterized by a lack or absence of sexual fantasies and desire for sexual activity in a situation that would normally produce sexual arousal, or the inability to attain or maintain typical responses to sexual arousal. The disorder is found in the DSM-IV. The condition should not be confused with a sexual desire disorder.
Sexual medicine or psychosexual medicine as defined by Masters and Johnsons in their classic Textbook of Sexual Medicine, is "that branch of medicine that focuses on the evaluation and treatment of sexual disorders, which have a high prevalence rate." Examples of disorders treated with sexual medicine are erectile dysfunction, hypogonadism, and prostate cancer. Sexual medicine often uses a multidisciplinary approach involving physicians, mental health professionals, social workers, and sex therapists. Sexual medicine physicians often approach treatment with medicine and surgery, while sex therapists often focus on behavioral treatments.
Pelvic pain is pain in the area of the pelvis. Acute pain is more common than chronic pain. If the pain lasts for more than six months, it is deemed to be chronic pelvic pain. It can affect both the male and female pelvis.
Sex and drugs refers to the influence of substances on sexual function and experience. Sex and drugs date back to ancient humans and have been interlocked throughout human history. Sexual performance is known as the execution of the act of sex and the quality of sexual activity. This includes elements such as libido, sexual function, sensation. Drugs are termed as any chemical substance that produces a physiological and or psychological change in an organism. Drugs categorized as psychoactive drugs, antihypertensive drugs, antihistamines, cancer treatment, and hormone medication have a significant impact on sexual performance. Various drugs result in different effects, both positive and negative. Negative effects may include low libido, erection issues, vaginal dryness and anorgasmia. Positive effects usually address these issues, overall enhancing sexual performance and contributing to a more enjoyable sexual experience. It is crucial to know that the impact of drugs on sexual performance varies among individuals, especially among different genders.
Delayed ejaculation (DE) is a man's inability or persistent difficulty in achieving orgasm, despite typical sexual desire and sexual stimulation. Generally, a man can reach orgasm within a few minutes of active thrusting during sexual intercourse, whereas a man with delayed ejaculation either does not have orgasms at all or cannot have an orgasm until after prolonged intercourse which might last for 30–45 minutes or more. Delayed ejaculation is closely related to anorgasmia.
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 which 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.
The Magic Wand aka the True Magic Wand, Magic Wand Original, Vibratex Magic Wand and Original Magic Wand is an AC-powered wand vibrator. It was originally manufactured for relieving tension and relaxing sore muscles; however, it is most known for its use as a sex toy. Japanese company Hitachi listed the device for business in the United States in 1968. Sex educator Betty Dodson popularized its use as a vibrator and masturbation aid for women during the sex-positive movement in the late 1960s. It functions effectively as a clitoral vibrator for reaching orgasm. The wand is 12 inches (30 cm) long and weighs 1.2 pounds (540 g) with stimulation provided by its rubberized 2.5-inch (64 mm) head.
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.
The National Survey of Sexual Health and Behavior is a decade-long nationally representative study of human sexual behavior. The research has been conducted in the United States by researchers from the Center for Sexual Health Promotion in the School of Public Health at Indiana University in Bloomington. Time magazine called the NSSHB "the most comprehensive survey of its kind in nearly two decades and the first to include teenagers." Former U.S. Surgeon General Dr. Joycelyn Elders has written the following about NSSHB findings: "These data are important for keeping the nation moving forward in the area of sexual health and well being. In the absence of scientific data available to construct an accurate and up-to-date view, opinions in the field of sexual science can vary widely from person to person."
Penile artery shunt syndrome (PASS) is an iatrogenic clinical phenomenon first described by Tariq Hakky, Christopher Yang, Jonathan Pavlinec, Kamal Massis, and Rafael Carrion within the Sexual Medicine Program in the Department of Urology, at the University of South Florida, and Ricardo Munarriz, of Boston University School of Medicine Department of Urology in 2013. It may be a cause of refractory erectile dysfunction in patients who have undergone penile revascularization surgery.
Cindy Meston is a Canadian-American clinical psychologist well-known for her research on the psychophysiology of female sexual arousal. She is a Full Professor of Clinical Psychology at the University of Texas at Austin, Director of the Female Sexual Psychophysiology Laboratory, and author of Why Women Have Sex. In 2016, the BBC, London, England named Meston one of the 100 most influential and inspirational women in the world.
Culley Clyde Carson III is an American retired urologist who specializes in Peyronie's disease, penile implants and erectile dysfunction. After serving two years as a flight surgeon with the United States Air Force, he took on a urology residency at the Mayo Clinic and then taught at the Duke University Medical Center as an assistant professor, subsequently gaining full professorship.
Hard flaccid syndrome (HFS), also known as hard flaccid (HF), is a rare, chronic condition characterized by a flaccid penis that remains in a firm, semi-rigid state in the absence of sexual arousal. Patients describe their flaccid penises as being firm to the touch, rubbery, shrunken, and retracted. This may be accompanied by pain, discomfort, and a range of additional symptoms. Though the exact cause is poorly understood, current research suggests that HFS is the result of excessive sympathetic activity in the smooth muscle tissue of the penis that is induced by a pathological activation of a theorized pelvic/pudendal-hypogastric reflex. This reflex is thought to be triggered by an injury to the erect penis, blunt trauma to the perineum, and cauda equina, among others. An emerging theory suggests that the real explanation for HFS is sympathetic nerve sprouting in the dorsal root ganglia following a peripheral nerve injury. The majority of patients are in their 20s–30s and symptoms significantly affect one's quality of life. Treatment usually involves a multi-modal approach utilizing a combination of alpha blockers, PDE5 inhibitors, and specialized pelvic floor physical therapy though there is not much evidence to support their efficacy and most patients reportedly do not benefit from currently available treatment options. Due to limited awareness and understanding of the condition within the scientific and medical communities, definitive treatment for HFS does not exist.
