Where is the male prostate located?

The male prostate is a normal gland in men. The male prostate can metabolize semen, which is a key component of semen. The male prostate is located at the tip of the bladder and the posterior urethra. The male prostate surrounds the posterior urethra and is in the shape of an inverted chestnut. The male prostate can be divided into the anterior lobe, the middle lobe, the posterior lobe and the bilateral lobes. In addition, the male prostate can be divided into the central zone, the transitional zone and the jugular venous zone.

Where is the male prostate located?

The area where the male prostate is caused is about 2 cm in front of the duodenum from the anus. If you touch it with your fingers, you can touch a slightly hard spherical area by inserting your fingers about 2 cm into the anus. This place is the male prostate.

What does the male prostate look like?

The size and appearance of the male prostate are very similar to an inverted chestnut, with its upper end closely attached to the bladder, its lower end aligned with the urogenital diaphragm, its front against the male's ischial tuberosity, and its back against the duodenum. The male's urethral opening passes through the middle of the male prostate gland duct. The male prostate has a thickness of about 4cm above, a vertical diameter of 3cm, and a front-to-back left-right diameter of about 2cm.

The function of male prostate

1. Transport function The male prostate has a urethral opening and two vas deferens passing through it. When a man ejaculates, the muscles of the male prostate and seminal vesicle contract, which can push the contents of the ejaculatory duct and seminal vesicle into the posterior urethra through the vas deferens and discharge them out of the body. In general, the male prostate has four key functions and fully exerts key functions in the human body.

2. Control urination function The male prostate surrounds the urethral opening and is close to the bladder neck, forming the proximal urethral opening wall. Its annular smooth muscle chemical fiber tightly surrounds the male prostate of the urethral opening and participates in the formation of the internal dilation of the urethral opening. When the desire to urinate is generated, the internal dilation relaxes with the contraction of the detrusor muscle, allowing urination to proceed smoothly.

3. Exocrine function The male prostate is the largest sex hormone in men and is also one of the exocrine glands in the body. It can metabolize semen and is a key component of semen. It plays a key role in the normal function of sperm and is very important for pregnancy. The metabolism of semen is controlled by androgens.

4. Endocrine effect: The male prostate contains abundant 5α-reductase, which can convert testosterone into dihydrotestosterone, which is more physiologically specific. Dihydrotestosterone plays a key role in the development of prostatic hyperplasia. By blocking 5α-reductase, the production of dihydrotestosterone can be reduced, thereby shrinking the hyperplastic male prostate tissue.
