Andrology (from , ''anēr'', genitive , ''andros'' 'man' and , ''-logia'') is a name for the medical specialty that deals with male health, particularly relating to the problems of the male reproductive system and urological problems that are unique to men. It is the parallel to gynecology, which deals with medical issues which are specific to female health, especially reproductive and urologic health. Process Andrology covers anomalies in the connective tissues pertaining to the genitalia, as well as changes in the volume of cells, such as in genital hypertrophy or macrogenitosomia. From reproductive and urologic viewpoints, male-specific medical and surgical procedures include vasectomy, vasovasostomy (one of the vasectomy reversal procedures), orchidopexy, circumcision, sperm/semen cryopreservation, surgical sperm retrieval, semen analysis (for fertility or post-vasectomy), sperm preparation for assisted reproductive technology (ART) as well as intervention to deal with male ...

Specialty (medicine)
A medical specialty is a branch of medical practice that is focused on a defined group of patients, diseases, skills, or philosophy. Examples include those branches of medicine that deal exclusively with children (pediatrics), cancer (oncology), laboratory medicine (pathology), or primary care (family medicine). After completing medical school or other basic training, physicians or surgeons and other Clinician, clinicians usually further their medical education in a specific specialty of medicine by completing a multiple-year residency (medicine), residency to become a specialist. History of medical specialization To a certain extent, medical practitioners have long been specialized. According to Galen, specialization was common among Roman physicians. The particular system of modern medical specialties evolved gradually during the 19th century. Informal social recognition of medical specialization evolved before the formal legal system. The particular subdivision of the practice ...

Orchidopexy
Orchiopexy (or orchidopexy) is a surgery to move and/or permanently fix a testicle into the scrotum. While orchiopexy typically describes the operation to surgically correct an undescended testicle, it is also used to resolve testicular torsion. Indications Undescended testicle Undescended testicles affect 1% of males and present bilaterally in 10% of those cases. The cause is unknown, with a small percentage associated with developmental abnormalities or chromosomal aberrations. Early orchiopexy reduces the risks for cancer and sterility in males with cryptorchidism, or undescended testes. Cryptorchidism is definitively diagnosed after 1 year of age, as testicular descent may occur after birth. Surgical placement into the scrotum is recommended by 18 months to decrease the likelihood of testicular cancer, testicular atrophy, and sterility. Cryptorchidism is associated with tubular atrophy and sterility. In addition, cryptorchid testes carry a three to five times higher risk f ...

Infertility
In biology, infertility is the inability of a male and female organism to Sexual reproduction, reproduce. It is usually not the natural state of a healthy organism that has reached sexual maturity, so children who have not undergone puberty, which is the body's start of fertility, reproductive capacity, are excluded. It is also a normal state in women after menopause. In humans, ''infertility'' is defined as the inability to become pregnant after at least one year of unprotected and regular sexual intercourse involving a male and female partner. There are many causes of infertility, including some that Assisted reproductive technology, medical intervention can treat. Estimates from 1997 suggest that worldwide about five percent of all heterosexual couples have an unresolved problem with infertility. Many more couples, however, experience involuntary childlessness for at least one year, with estimates ranging from 12% to 28%. Male infertility is responsible for 20–30% of infert ...

Hypospadias
Hypospadias is a common malformation in fetal development of the penis in which the urethra does not open from its usual location on the head of the penis. It is the second-most common birth defect of the male reproductive system, affecting about one of every 250 males at birth, although when including milder cases, is found in up to 4% of newborn males. Roughly 90% of cases are the less serious distal hypospadias, in which the urethral opening (the Urinary meatus, meatus) is on or near the head of the penis (Glans penis, glans). The remainder have proximal hypospadias, in which the meatus is all the way back on the shaft of the penis, near or within the scrotum. Shiny tissue or anything that typically forms the urethra instead extends from the meatus to the tip of the glans; this tissue is called the urethral plate. In most cases, the foreskin is less developed and does not wrap completely around the penis, leaving the underside of the glans uncovered. Also, a downward bending of ...

Hydrocele
A hydrocele is an accumulation of serous fluid in a body cavity. A hydrocele testis, the most common form of hydrocele, is the accumulation of fluids around a testicle. It is often caused by fluid collecting within a layer wrapped around the testicle, called the tunica vaginalis, which is derived from peritoneum. Provided there is no hernia present, it goes away without treatment in the first year. Although hydroceles usually develop in males, rare instances have been described in females in the canal of Nuck. Primary hydroceles may develop in adulthood, particularly in the elderly and in hot countries, by slow accumulation of serous fluid. This is presumably caused by impaired reabsorption, which appears to be the explanation for most primary hydroceles, although the reason remains obscure. A hydrocele can also be the result of a plugged inguinal lymphatic system caused by repeated, chronic infection of ''Wuchereria bancrofti'' or ''Brugia malayi'', two mosquito-borne parasit ...

Frenulum Breve
Frenulum breve, or short frenulum, is a condition in which the Frenulum preputii penis, frenulum of the penis, which is an elastic band of tissue under the glans penis that connects to the foreskin and helps contract it over the glans, is too short and thus restricts the movement of the foreskin. The frenulum should normally be sufficiently long and supple to allow for the full retraction of the foreskin so that it lies smoothly back on the shaft of the erect penis. The penile frenulum is comparable to the Frenulum of tongue, tongue's frenulum between the tongue's lower surface and the lower jaw, or the frenulum between the upper lip and the outside of the upper gum. Symptoms and signs A frenulum breve leads to ventral deviation of the glans and pain during erection. Sometimes, tearing of the frenulum causes heavy bleeding. The tearing of frenulum breve occurs particularly during sexual activity of young men. Frenulum breve may be complicated by tearing of the frenulum during s ...

Erectile Dysfunction
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 Human penis, 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. The 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, Hypertension, high blood pressure, obesity, Dyslipidemia, abnormal lipid levels in the blood, hypogonadism, smoking, Depression (mood), depression, and Adverse drug reactions, medication use. Approximately 10% of cases are linked to psychosocial factors, encompassing conditions such as depressio ...

Epispadias
Epispadias is a birth defect in which the urethra fails to fully develop, resulting in urine leaving the body from an abnormal site. In males, this may be an opening on the upper aspect of the penis, and in females when the urethra develops too far anteriorly. It occurs in around 1 in 120,000 male and 1 in 500,000 female births. Signs and symptoms Most cases involve a small and bifid penis, which requires surgical closure soon after birth, often including a reconstruction of the urethra. Where it is part of a larger exstrophy, not only the urethra but also the bladder ( bladder exstrophy) or the entire perineum ( cloacal exstrophy) are open and exposed on birth, requiring closure. Relationship to other conditions Despite the similarity of name, an epispadias is not a type of hypospadias, and involves a problem with a different set of embryologic processes. Women can also have this type of congenital malformation. Epispadias of the female may occur when the urethra develops t ...

Epididymitis
Epididymitis is a medical condition characterized by inflammation of the epididymis, a curved structure at the back of the testicle. Onset of pain is typically over a day or two. The pain may improve with raising the testicle. Other symptoms may include swelling of the testicle, burning with urination, or frequent urination. Inflammation of the testicle is commonly also present. In those who are young and sexually active, gonorrhea and chlamydia are frequently the underlying cause. In older males and men who practice insertive anal sex, enteric bacteria are a common cause. Diagnosis is typically based on symptoms. Conditions that may result in similar symptoms include testicular torsion, inguinal hernia, and testicular cancer. Ultrasound can be useful if the diagnosis is unclear. Treatment may include pain medications, NSAIDs, and elevation. Recommended antibiotics in those who are young and sexually active are ceftriaxone and doxycycline. Among those who are older, ofloxaci ...

Cryptorchidism
Cryptorchidism, also known as undescended testis, is the failure of one or both testes to descend into the scrotum. The word is . It is the most common birth defect of the male genital tract. About 3% of full-term and 30% of premature infant boys are born with at least one undescended testis. However, about 80% of cryptorchid testes descend by the first year of life (the majority within three months), making the true incidence of cryptorchidism around 1% overall. Cryptorchidism may develop after infancy, sometimes as late as young adulthood, but that is exceptional. Cryptorchidism is distinct from monorchism, the condition of having only one testicle. Though the condition may occur on one or both sides, it more commonly affects the right testis. A testis absent from the normal scrotal position may be: # Anywhere along the "path of descent" from high in the posterior (retroperitoneal) abdomen, just below the kidney, to the inguinal ring # In the inguinal canal # Ectopic, havin ...

Carcinoma Of The Penis
Penile cancer, or penile carcinoma, is a cancer that develops in the skin or tissues of the penis. Symptoms may include abnormal growth, an ulcer or sore on the skin of the penis, and bleeding or foul smelling discharge. Risk factors include phimosis (inability to retract the foreskin of the penis), chronic inflammation, smoking, HPV infection, condylomata acuminate, having multiple sexual partners, and early age of sexual intercourse. Around 95% of penile cancers are squamous-cell carcinomas. Other types of penile cancer such as Merkel-cell carcinoma, small-cell carcinoma, and melanoma are generally rare. In 2020, it occurred in 36,000 men and caused 13,000 deaths. Signs and symptoms Penile cancer can present as redness and irritation on the penis with a skin thickening on the glans or inner foreskin or an ulcerative, outward growingexophytic or “finger-like” (papillary) growth. Penile cancer may accompany penile discharge with or without difficulty or burning or tingling w ...

Balanitis
Balanitis is inflammation of the glans penis. Balanoposthitis is the proper term when the foreskin is also affected. Balanitis on boys in diapers must be distinguished from redness caused by ammoniacal dermatitis. Etymology The word ''balanitis'' is from the Greek βάλανος'' '', literally meaning 'acorn' because of the similarity in shape to the glans penis. ''-Itis'' is a suffix from the Greek for 'inflammation'. ''Posthe'' is the Greek word meaning 'foreskin'. Signs and symptoms * Small red erosions on the glans (first sign) * Redness of the foreskin * Redness of the penis * Other rashes on the head of the penis * Foul-smelling discharge * Painful foreskin and penis Complications Recurrent bouts of balanitis may cause scarring of the preputial orifice; the reduced elasticity may lead to pathologic phimosis. Further complications may include: * Stricture of urinary meatus * Paraphimosis Causes Inflammation has many possible causes, including irritation by environ ...
