Ejaculation

ejaculateejaculatedejaculates
The prostate also contains some smooth muscles that also help expel semen during ejaculation.
In rare cases, ejaculation occurs because of prostatic disease.

Seminal vesicle

seminal vesiclesvesicula seminalisvesicular gland
This prostatic fluid is slightly alkaline, milky or white in appearance, and in humans usually constitutes roughly 30% of the volume of semen, the other 70% being spermatozoa and seminal vesicle fluid.
The excretory duct of each seminal gland unites with the corresponding vas deferens to form the two ejaculatory ducts, which immediately pass through the substance of the prostate gland before opening separately into the verumontanum of the prostatic urethra.

Semen

seminal fluidseminalsperm
The function of the prostate is to secrete a fluid which contributes to the volume of the semen.
During the process of ejaculation, sperm passes through the ejaculatory ducts and mixes with fluids from the seminal vesicles, the prostate, and the bulbourethral glands to form the semen.

Prostate cancer

prostatehormone-refractory prostate cancermetastatic prostate cancer
Disorders of the prostate include enlargement, inflammation, infection, and cancer.
Prostate cancer is the development of cancer in the prostate, a gland in the male reproductive system.

Male reproductive system

male genitaliamale genital organsmale reproductive organs
The prostate is an exocrine gland of the male reproductive system in most mammals.
They are the seminal vesicles, the prostate gland, and the bulbourethral glands (Cowper glands).

Urinary bladder

bladderfundusintravesical
The prostate surrounds the urethra just below the urinary bladder and can be felt during a rectal exam.
In males the neck of the urinary bladder is adjacent to the prostate gland.

Spermatozoon

spermatozoaspermsperm cells
This prostatic fluid is slightly alkaline, milky or white in appearance, and in humans usually constitutes roughly 30% of the volume of semen, the other 70% being spermatozoa and seminal vesicle fluid.
Just as they become hypermotile, fibrinolysin from the prostate gland dissolves the clot, allowing the sperm to progress optimally.

Ejaculatory duct

ejaculatory ducts
Within it sits the urethra coming from the bladder which is called the prostatic urethra and which merges with the two ejaculatory ducts.
They pass through the prostate, and open into the urethra at the seminal colliculus.

Urethra

male urethraurethralFemale urethra
The prostate surrounds the urethra just below the urinary bladder and can be felt during a rectal exam. Condensation of mesenchyme, urethra, and Wolffian ducts gives rise to the adult prostate gland, a composite organ made up of several tightly fused glandular and non-glandular components. The surgery most often used in such cases is called transurethral resection of the prostate, in which an instrument is inserted through the urethra to remove prostate tissue that is pressing against the upper part of the urethra and restricting the flow of urine.

Prostatic acid phosphatase

ACP3PAPACPP
Some of the prostate specific proteins are enzymes, such as the prostate specific antigen (PSA), and the ACPP protein.
Prostatic acid phosphatase (PAP), also prostatic specific acid phosphatase (PSAP), is an enzyme produced by the prostate.

Vagina

birth canalvaginalvaginal opening
The alkalinity of semen helps neutralize the acidity of the vaginal tract, prolonging the lifespan of sperm.
A G-spot orgasm may be responsible for female ejaculation, leading some doctors and researchers to believe that G-spot pleasure comes from the Skene's glands, a female homologue of the prostate, rather than any particular spot on the vaginal wall; other researchers consider the connection between the Skene's glands and the G-spot area to be weak.

Vesical venous plexus

vesical plexusbladdervescial plexus
This network also receives blood from the deep dorsal vein of the penis, and is connected via branches (rami) to the vesical plexus and internal pudendal veins.
The vesical plexus envelops the lower part of the bladder and the base of the prostate and communicates with the pudendal and prostatic plexuses.

Testosterone

low testosterone levels due to agingmetabolismprenatal exposure to androgens
The main male hormone is testosterone, which is produced mainly by the testicles.
In male humans, testosterone plays a key role in the development of male reproductive tissues such as testes and prostate, as well as promoting secondary sexual characteristics such as increased muscle and bone mass, and the growth of body hair.

Dihydrotestosterone

5α-DihydrotestosteroneDHT17-hydroxyandrostan-3-one
It is dihydrotestosterone (DHT), a metabolite of testosterone, that predominantly regulates the prostate.
The enzyme 5α-reductase catalyzes the formation of DHT from testosterone in certain tissues including the prostate gland, seminal vesicles, epididymides, skin, hair follicles, liver, and brain.

Anal sex

analanal intercourseanal penetration
It is possible for some men to achieve orgasm solely through stimulation of the prostate gland, such as prostate massage or anal intercourse.
People may experience pleasure from anal sex by stimulation of the anal nerve endings, and orgasm may be achieved through anal penetration – by indirect stimulation of the prostate in men, indirect stimulation of the clitoris or an area of the vagina (sometimes called the G-spot) in women, and other sensory nerves (especially the pudendal nerve).

Prostatic urethra

pars prostaticaprostaticprostatic portion of the urethra
Within it sits the urethra coming from the bladder which is called the prostatic urethra and which merges with the two ejaculatory ducts.
A transverse section of the canal as it lies in the prostate is horse-shoe-shaped, with the convexity directed forward.

Rectal examination

digital rectal examinationdigital rectal examanal probe
The prostate is enlarged (prostatomegaly) and tender on digital rectal examination.
In veterinary medicine rectal examination is useful in dogs for analysis of the prostate (as in men), pelvic urethra, sublumbar lymph nodes, and anal glands.

Prostatitis

Prostatitis is inflammation of the prostate gland.
Prostatitis is inflammation of the prostate gland.

Orgasm

It is possible for some men to achieve orgasm solely through stimulation of the prostate gland, such as prostate massage or anal intercourse.
They may also achieve orgasm by stimulation of the prostate (see below).

Benign prostatic hyperplasia

enlarged prostatebenign prostatic hypertrophybenign prostate hyperplasia
Benign prostatic hyperplasia refers to a non-malignant enlargement of the prostate that is very common in older men.
Benign prostatic hyperplasia (BPH), also called prostate enlargement, is a noncancerous increase in size of the prostate gland.

Mesonephric duct

Wolffian ductWolffian ductsWolffian structures
Condensation of mesenchyme, urethra, and Wolffian ducts gives rise to the adult prostate gland, a composite organ made up of several tightly fused glandular and non-glandular components.
The prostate forms from the urogenital sinus and the efferent ducts form from the mesonephric tubules.

Dysuria

Inflammation of the prostate can cause painful urination or ejaculation, groin pain, difficulty passing urine, or constitutional symptoms.
It may also be due to an STD, bladder stones, bladder tumors, and virtually any condition of the prostate.

Biopsy

biopsiestissue biopsybiopsied
A study stated that prostate volume among patients with negative biopsy is related significantly with weight and height (body mass index), so it is necessary to control for weight.

Vas deferens

ductus deferensvasa deferentiasperm duct
During male seminal emission, sperm is transmitted from the vas deferens into the male urethra via the ejaculatory ducts, which lie within the prostate gland.
The sperm is transferred from the vas deferens into the urethra, collecting secretions from the male accessory sex glands such as the seminal vesicles, prostate gland and the bulbourethral glands, which form the bulk of semen.

Transurethral resection of the prostate

transurethral resectiontransurethral resection of prostateTURP
The surgery most often used in such cases is called transurethral resection of the prostate, in which an instrument is inserted through the urethra to remove prostate tissue that is pressing against the upper part of the urethra and restricting the flow of urine.
As the name indicates, it is performed by visualising the prostate through the urethra and removing tissue by electrocautery or sharp dissection.
