Male Genital Disorders
A male genital disease is a condition that affects the male reproductive system. The human male genitals consist of testicles and epididymides, '' ductus deferentes'', seminal vesicles and ejaculatory ducts, prostate, bulbourethral glands, and penis. Classification by type of disease Infection Aetiological agents =Bacterial= * Erythrasma * Balanoposthitis * Fournier's Gangrene =Fungus= * Candidiasis * ''Tinea cruris'' =Parasites= * Cutaneous larva migrans * Pubic lice * Scabies * Tick =Virus= * ''Molluscum contagiosum'' * Herpes: simplex, zoster Cancers The probability of contracting a cancerous development depends on age, ethnicity and the existence, or non-existence, of environmental causation. Unlike all other genitally situated cancers, the incidence of penis cancer is related to the sexual mode of transmission. Inflammation An example of a male genital disease is orchitis. Classification by location of disease Penis * Mondor's disease is a non-common disease * P ...

Male Reproductive System (human)
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. External genitalia Penis The penis is an intromittent organ with a long shaft, an enlarged bulbous-shaped tip called the glans and its foreskin for protection. Inside the penis is the urethra, which is used to ejaculate semen and to excrete urine. Both substances exit through the meatus. When a male becomes sexually aroused, erection occurs because sinuses within the erectile tissues of the penis ( corpora cavernosa and corpus ...

Scabies
Scabies (; also sometimes known as the seven-year itch) is a contagious human skin infestation by the tiny (0.2–0.45 mm) mite ''Sarcoptes scabiei'', variety ''hominis''. The word is from . The most common symptoms are severe itchiness and a papular, pimple-like rash. Occasionally, tiny burrows may appear on the skin. In a first-ever infection, the infected person usually develops symptoms within two to six weeks. During a second infection, symptoms may begin within 24 hours. These symptoms can be present across most of the body or just in certain areas such as the wrists, between fingers, or along the waistline. The head may be affected, but this is typically only in young children. The itch is often worse at night. Scratching may cause skin breakdown and an additional bacterial infection in the skin. Various names have been given to this condition and the name 'seven year itch' has been recorded in many documents from the 1800's. Although the 1952 The_Seven_Year_Itch_( ...

Tunica Albuginea (penis)
The tunica albuginea is the fibrous envelope that extends the length of the corpus cavernosum penis and corpus spongiosum penis. It is a bi-layered structure that includes an outer longitudinal layer and an inner circular layer. Structure Microstructure The trabeculae of the tunica albuginea are more delicate, nearly uniform in size, and the meshes between them smaller than in the corpora cavernosa penis: their long diameters, for the most part, corresponding with that of the penis. The external envelope or outer coat of the corpus spongiosum is formed partly of unstriped muscular fibers, and a layer of the same tissue immediately surrounds the canal of the urethra. It consists of approximately 5% elastin, with the remainder mostly consisting of collagen. Function The tunica albuginea is directly involved in maintaining an erection; that is due to Buck's fascia constricting the erection veins of the penis, preventing blood from leaving and thus sustaining the erect stat ...

Peyronie's Disease
Peyronie's disease (PD) is a benign, acquired penile connective tissue disease characterized by the occurrence of fibrotic plaques within the Tunica albuginea (penis), tunica albuginea — the dense elastic covering of the Corpora cavernosa of penis, corpora cavernosa. The plaques cause abnormal curvature, pain, penile deformities (e.g., narrowing or indentation), and usually erectile dysfunction, particularly during erection. The condition typically leads to significant sexual and psychological effects, including difficulty with penetration and lowered self-esteem or evasiveness. Peyronie's disease is most often seen in middle-aged and older men with a median age of onset between 55 and 60 years, although it has also been noted in younger individuals and adolescents. While the etiology of PD is still a mystery, the leading hypothesis is that it arises from dysregulated wound healing in response to Chronic condition, chronic microtrauma of the erect penis. This triggers a cascade ...

Orchitis
Orchitis is inflammation of the testicles. It can also involve swelling, pains, and frequent infection, particularly of the epididymis, as in epididymitis. The term is from the Ancient Greek ὄρχις meaning "testicle"; same root as ''orchid''. Signs and symptoms Symptoms of orchitis are similar to those of testicular torsion. These can include: * hematospermia (blood in the semen) * hematuria (blood in the urine) * severe pain * visible swelling of a testicle or testicles and often the inguinal lymph nodes on the affected side. Causes Orchitis can be related to epididymitis infection that has spread to the testicles (then called "epididymo-orchitis"), sometimes caused by the sexually transmitted infections chlamydia and gonorrhea. It has also been reported in cases of males infected with brucellosis. Orchitis can also be seen during active mumps, particularly in adolescent boys and girls. Ischemic orchitis may result from damage to the blood vessels of the spermatic ...

Clinics In Office Practice
A clinic (or outpatient clinic or ambulatory care clinic) is a health facility that is primarily focused on the care of outpatients. Clinics can be privately operated or publicly managed and funded. They typically cover the primary care needs of populations in local communities, in contrast to larger hospitals which offer more specialized treatments and admit inpatients for overnight stays. Most commonly, the English word ''clinic'' refers to a general practice, run by one or more general practitioners offering small therapeutic treatments, but it can also mean a specialist clinic. Some clinics retain the name "clinic" even while growing into institutions as large as major hospitals or becoming associated with a hospital or medical school. Etymology The word ''clinic'' derives from Ancient Greek ''klinein'' meaning to slope, lean or recline. Hence ''klinē'' is a couch or bed and ''klinikos'' is a physician who visits his patients in their beds. In Latin, this became ''cl ...

Herpes Zoster
Shingles, also known as herpes zoster or zona, is a viral disease characterized by a painful skin rash with blisters in a localized area. Typically the rash occurs in a single, wide mark either on the left or right side of the body or face. Two to four days before the rash occurs there may be tingling or local pain in the area. Other common symptoms are fever, headache, and tiredness. The rash usually heals within two to four weeks, but some people develop ongoing nerve pain which can last for months or years, a condition called postherpetic neuralgia (PHN). In those with poor immune function the rash may occur widely. If the rash involves the eye, vision loss may occur. Shingles is caused by the varicella zoster virus (VZV) that also causes chickenpox. In the case of chickenpox, also called varicella, the initial infection with the virus typically occurs during childhood or adolescence. Once the chickenpox has resolved, the virus can remain dormant (inactive) in human n ...
