A gland that secretes a fluid contributing to the total volume of semen.
An O-shaped gland in males which surrounds the urethra below the bladder and secretes a fluid containing enzymes into the sperm.
A muscular organ containing 30-50 tubuloalveolar glands that encompass the junction of the ejaculatory duct with the male urethra.
An oval organ in males that secretes fluid that mixes with sperm to form semen. The prostate gland sits just under the bladder, and the urethra passes through it. Tiny at birth, the prostate begins to grow at puberty, triggered by male sex hormones, reaching adult size by the end of the teens. In older men the prostate becomes further enlarged, which can cause painful urination, and sometimes becomes cancerous. In younger men, the main prostate problem is bacterial infection, often from sexually transmitted diseases.
A walnut-sized organ located just below the bladder and in front of the rectum in males. The gland produces fluids that form part of semen, the fluid released during ejaculation. Muscular tissue in the prostate also has a role in ejaculation. The prostate gland consists of two main parts; the inner part produces the secretions that keep the lining of the urethra moist, and the outer part produces the secretions that mix with sperm.
A male accessory sex gland that opens into the urethra just below the bladder and vas deferens. During ejaculation it secretes an alkaline fluid that forms part of the semen. The prostate may become enlarged in elderly men. This obstructs the neck of the bladder, impairing urination. The bladder dilates and the increased pressure is transmitted through the ureters to the kidney nephrons, leading to damage and impaired function of the kidneys. Treatment is by prostatectomy.
This is an accessory sex gland in males which is wrapped round the urethra as this tube leaves the urinary bladder. Opening into the urethra, the gland secretes an alkaline fluid during ejaculation and is a constituent of semen. The gland grows during adolescence and is sensitive to the concentrations of sex hormones.
The male gland that surrounds the neck of the bladder and the urethra. It is partly glandular, with ducts opening into the prostatic portion of the urethra, and partly muscular. It secretes a thin, opalescent, slightly alkaline fluid that forms part of the semen. The prostate consists of a median lobe and two lateral lobes measuring about 2 X 4 X 3 cm and weighing about 20 g; it is enclosed in a fibrous capsule containing smooth muscle fiber in its inner layer. The nerve supply is from the inferior hypogastric plexus.
A gland in males that adds fluids that nourish and protect sperm as the sperm move through the female body.
In males, a gland located near the bladder that provides 35 percent of the fluid to semen.
A firm, chestnut-like organ, the prostate gland encircles the initial segment of the male urethra and is located directly below the bladder. The gland produces fluids that contribute to the seminal fluid released during ejaculation.
The prostate gland is divided into two separate areas: an inner zone that generates fluids to moisten the urethra’s lining, and an outer zone responsible for seminal fluids. Two ejaculatory ducts travel from the seminal vesicles, passing through the prostate gland to join the urethra. These ducts transport fluids and nutrients from the vesicles to be incorporated into the semen. The prostate gland is quite small at birth, weighing just a few grams. It enlarges during puberty due to the influence of androgen hormones and reaches its adult size around the age of 20. For most men, the prostate gland starts to further enlarge after the age of 50.
Several conditions can impact the prostate gland, including benign prostatic hypertrophy, cancer, and prostatitis, which is an inflammation of the gland.
The prostate is an organ in males that encircles the neck of the bladder and the start of the urethra. It comprises two side lobes and a central lobe, made up of both muscular and glandular tissues. Multiple ducts from the prostate lead to the urethra. The gland likely produces a fluid that combines with semen, serving as both a nourishing substance and a lubricant to aid the semen in its journey to fertilize the female egg.
