Most zinc is in the brain, muscle, bones, kidney, and liver, with the highest concentrations in the prostate and parts of the eye. [11] Semen is particularly rich in zinc, a key factor in prostate gland function and reproductive organ growth. [12] Zinc homeostasis of the body is mainly controlled by the intestine.
In some marsupial species, the size of the prostate gland changes seasonally. [64] The prostate is the only accessory gland that occurs in male dogs. [65] Dogs can produce in one hour as much prostatic fluid as a human can in a day. They excrete this fluid along with their urine to mark their territory. [66]
The male accessory glands are the ampullary gland, seminal vesicle, prostate, bulbourethral gland, and urethral gland. [5]The products of these glands serve to nourish and activate the spermatozoa, to clear the urethral tract prior to ejaculation, serve as the vehicle of transport of the spermatozoa in the female tract, and to plug the female tract after placement of spermatozoa to help ensure ...
prostate: 25–30%: Acid phosphatase, citric acid, fibrinolysin, prostate specific antigen, proteolytic enzymes, zinc. (The zinc level is about 135 ± 40 μg/mL for healthy men. [8] Zinc serves to help to stabilize the DNA-containing chromatin in the sperm cells. A zinc deficiency may result in lowered fertility because of increased sperm ...
Most zinc is in the brain, muscle, bones, kidney, and liver, with the highest concentrations in the prostate and parts of the eye. [197] Semen is particularly rich in zinc, a key factor in prostate gland function and reproductive organ growth. [198] Zinc homeostasis of the body is mainly controlled by the intestine.
Ejaculation occurs in two stages, the emission stage and the expulsion stage. [4] The emission stage involves the workings of several structures of the ejaculatory duct; contractions of the prostate gland, the seminal vesicles, the bulbourethral gland and the vas deferens push fluids into the prostatic urethra.

Three accessory glands provide fluids that lubricate the duct system and nourish the sperm cells. Seminal vesicles : two glands behind the bladder that secrete many of the semen's components. Prostate gland : a gland located below the bladder that produces seminal fluid and helps regulate urine flow.
The seminal vesicles (also called vesicular glands [1] or seminal glands) are a pair of convoluted tubular accessory glands that lie behind the urinary bladder of male mammals. They secrete fluid that largely composes the semen. The vesicles are 5–10 cm in size, 3–5 cm in diameter, and are located between the bladder and the rectum.
