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. [3]

Inflammation

An example of a male genital disease is orchitis.[ citation needed ]

Classification by location of disease

Penis

Prostate

The three most statistically frequently occurring diseases of the prostate gland are benign hyperplasia (a swelling of the gland, not due to cancerous accumulation), prostatitis (inflammation), and cancer [6] (which is the accumulation of malignant cells in the gland). [7]

Urology, also known as genitourinary surgery, is the branch of medicine that focuses on surgical and medical diseases of the urinary system and the reproductive organs. Organs under the domain of urology include the kidneys, adrenal glands, ureters, urinary bladder, urethra, and the male reproductive organs.

<span class="mw-page-title-main">Prostate</span> Gland of the male reproductive system

The prostate is both an accessory gland of the male reproductive system and a muscle-driven mechanical switch between urination and ejaculation. It is found in all male mammals. It differs between species anatomically, chemically, and physiologically. Anatomically, the prostate is found below the bladder, with the urethra passing through it. It is described in gross anatomy as consisting of lobes and in microanatomy by zone. It is surrounded by an elastic, fibromuscular capsule and contains glandular tissue, as well as connective tissue.

<span class="mw-page-title-main">Prostate cancer</span> Male reproductive organ cancer

Prostate cancer is the uncontrolled growth of cells in the prostate, a gland in the male reproductive system below the bladder. Abnormal growth of prostate tissue is usually detected through screening tests, typically blood tests that check for prostate-specific antigen (PSA) levels. Those with high levels of PSA in their blood are at increased risk for developing prostate cancer. Diagnosis requires a biopsy of the prostate. If cancer is present, the pathologist assigns a Gleason score, and a higher score represents a more dangerous tumor. Medical imaging is performed to look for cancer that has spread outside the prostate. Based on the Gleason score, PSA levels, and imaging results, a cancer case is assigned a stage 1 to 4. A higher stage signifies a more advanced, more dangerous disease.

<span class="mw-page-title-main">Peyronie's disease</span> Abnormal growth of scar tissue within the penis

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.

Smegma is a combination of shed skin cells, skin oils, and moisture. It occurs in both male and female mammalian genitalia. In females, it collects around the clitoris and in the folds of the labia minora; in males, smegma collects under the foreskin.

Andrology 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 counterpart to gynecology, which deals with medical issues which are specific to female health, especially reproductive and urologic health.

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.

<span class="mw-page-title-main">Hyperplasia</span> Enlargement of tissue due to cell proliferation

Hyperplasia, or hypergenesis, is an enlargement of an organ or tissue caused by an increase in the amount of organic tissue that results from cell proliferation. It may lead to the gross enlargement of an organ, and the term is sometimes confused with benign neoplasia or benign tumor.

<span class="mw-page-title-main">Pearly penile papules</span> Small bumps on the head of the human penis

Pearly penile papules are benign, small bumps or spots on the human penis. They vary in size from 1–4 mm, are pearly or flesh-colored, smooth and dome-topped or filiform, and appear in one or, several rows around the corona, the ridge of the head of the penis and sometimes on the penile shaft. They are painless, non-cancerous and not harmful. The medical condition of having such papules is called hirsutoid papillomatosis or hirsuties papillaris coronae glandis.

The Gleason grading system is used to help evaluate the prognosis of men with prostate cancer using samples from a prostate biopsy. Together with other parameters, it is incorporated into a strategy of prostate cancer staging which predicts prognosis and helps guide therapy. A Gleason score is given to prostate cancer based upon its microscopic appearance.

Vaginectomy is a surgery to remove all or part of the vagina. It is one form of treatment for individuals with vaginal cancer or rectal cancer that is used to remove tissue with cancerous cells. It can also be used in gender-affirming surgery. Some people born with a vagina who identify as trans men or as nonbinary may choose vaginectomy in conjunction with other surgeries to make the clitoris more penis-like (metoidioplasty), construct of a full-size penis (phalloplasty), or create a relatively smooth, featureless genital area.

A reproductive system disease is any disease of the human reproductive system.

<span class="mw-page-title-main">Human penis</span> Human male external reproductive organ

In human anatomy, the penis is an external male sex organ that serves as a passage for excretion of urine and ejaculation of semen. The main parts are the root, body, the epithelium of the penis including the shaft skin, and the foreskin covering the glans. 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 urethra passes through the prostate gland, where it is joined by the ejaculatory ducts, and then through the penis. The urethra goes across the corpus spongiosum and ends at the tip of the glans as the opening, the urinary meatus.

The development of the reproductive system is the part of embryonic growth that results in the sex organs and contributes to sexual differentiation. Due to its large overlap with development of the urinary system, the two systems are typically described together as the genitourinary system.

<span class="mw-page-title-main">Sodium-coupled monocarboxylate transporter 1</span> Protein-coding gene in the species Homo sapiens

Sodium-coupled monocarboxylate transporter 1 (i.e., SMCT1) and sodium-coupled monocarboxylate transporter 2 (i.e., SMCT2) are plasma membrane transport proteins in the solute carrier family. They transport sodium cations in association with the anionic forms (see conjugated base) of certain short-chain fatty acids (i.e., SC-FAs) through the plasma membrane from the outside to the inside of cells. For example, propionic acid (i.e., CH
3
CH
2
CO

H
) in its anionic "propionate" form (i.e., CH
3
CH
2
CO
2
) along with sodium cations (i.e., Na+) are co-transported from the extracellular fluid into a SMCT1-epxressing cell's cytoplasm. Monocarboxylate transporters (MCTs) are also transport proteins in the solute carrier family. They co-transport the anionic forms of various compounds into cells in association with proton cations (i.e. H+). Four of the 14 MCTs, i.e. SLC16A1 (i.e., MCT1), SLC16A7 (i.e., MCT22), SLC16A8 (i.e., MCT3), and SLC16A3 (i.e., MCT4), transport some of the same SC-FAs anions that the SMCTs transport into cells. SC-FAs do diffuse into cells independently of transport proteins but at the levels normally occurring in tissues far greater amounts of the SC-FAs are brought into cells that express a SC-FA transporter.

<span class="mw-page-title-main">Scrotum</span> Sac of skin that protects the testicles

In most terrestrial mammals, the scrotum or scrotal sac is a part of the external male genitalia located at the base of the penis. It consists of a sac of skin containing the external spermatic fascia, testicles, epididymides, and vasa deferentia. The scrotum will usually tighten when exposed to cold temperatures.

<span class="mw-page-title-main">Human penis size</span> Measurement of the human penis

Human penises vary in size on a number of measures, including length and circumference when flaccid and erect. Besides the natural variability of human penises in general, there are factors that lead to minor variations in a particular male, such as the level of arousal, time of day, ambient temperature, anxiety level, physical activity, and frequency of sexual activity. Compared to other primates, including large examples such as the gorilla, the human penis is thickest, both in absolute terms and relative to the rest of the body. Most human penis growth occurs in two stages: the first between infancy and the age of five; and then between about one year after the onset of puberty and, at the latest, approximately 17 years of age.

Male genital examination is a physical examination of the genital in males to detect ailments and to assess sexual development, and is normally a component of an annual physical examination. The examination includes checking the penis, scrotum, and urethral meatus. A comprehensive assessment of the male genitals assesses the pubic hair based on Sexual Maturity Rating and the size of the testicles and penis. The exam can also be conducted to verify a person's age and biological sex. The genitourinary system can also be assessed as part of the male genital examination. During a genital examination, the doctor can detect any of the following: structural abnormalities, urethral opening abnormalities, problems related to not being circumcised, lumps, tumors, redness, excoriation, edema, lesions, swelling, cancer, hair-related issues, and many others. In some instances where a physical examination of the male genitals is not sufficient to diagnose an individual, then an internal genital examination using imaging or ultrasounds will be needed for further evaluation.
