Where is a man's sperm?

The formation of a fertilized egg requires the combination of sperm and egg. Therefore, male sperm has become an important component of human society's reproduction of the next generation. However, for most men, they don't know much about their own body structure, so these men don't know where the sperm is located in the body. The following will explain to male friends the location of sperm and how to protect it.

Where is a man's sperm stored after it is formed?

What is sperm?

Sperm can be divided into animal sperm and plant sperm. Male cells in the process of sexual reproduction of animals, reproductive cells of male animals, male gametes in heterogamous reproduction, and haploid reproductive cells produced by the spermatorrhea. In life, sperm refers more to mature male reproductive cells, which are formed in the testis. Semen is an organic substance. Semen contains fructose and protein, as well as some enzymes, inorganic salts and organic salts.

Where is sperm stored after it is formed?

After the formation of the testis, human sperm is gradually transported from the epididymis head to the tail, which takes about 2 weeks and further matures to become capable of fertilization. The survival time of sperm stored in the tail of the epididymis varies among species, but in humans it is about 1 to 2 months. Moreover, the testicles are continuously producing sperm and transporting them forward continuously, which ensures a sufficient source of sperm, and the sperm stored in the epididymis will not be ejaculated due to temptation. In order to reproduce the species, it always retains enough strength, so ejaculation will not empty the sperm stored in the epididymis all at once.

How to judge the health of a man's sperm

How to judge the health of a man's sperm

The main indicators of male sperm quality are as follows. How to judge the health of a man's sperm? Just look at the following indicators.

(1) Motility: ≥50% of sperm move rapidly in a straight line.

(2) Viscosity: When a glass rod is placed in contact with liquefied semen and gently lifted, a semen thread will form. Normally, its length is less than 2 cm.

(3) Liquefaction time: After normal semen is ejaculated, it becomes jelly-like under the action of the seminal vesicle coagulase. After 15 to 30 minutes, it becomes liquid under the action of the prostate liquefaction enzyme. This is called semen liquefaction. If semen still does not liquefy 30 minutes after ejaculation, it is abnormal.

(4) Color: Normal color is off-white or slightly yellow. Milky white or yellow-green indicates inflammation of the reproductive tract or accessory glands. Pink, red, or red blood cells under a microscope indicate bloody semen, which is commonly seen in inflammation of the accessory glands or posterior urethra, and occasionally in tuberculosis or tumors.

(5) Semen volume: Normal ≥ 2ml. If it is greater than 7ml, it is too much. Not only will the sperm density be reduced, but it will also be easy to flow out of the vagina, resulting in a decrease in the total number of sperm. This is common in seminal vesiculitis. If it is less than 2ml, it is too little semen, but usually less than 1ml is too little. At this time, the contact area between the semen and the female reproductive tract is small, or the viscosity makes it difficult for the sperm to enter the female cervix, leading to infertility. This is common in severe paragonitis, low testosterone levels, ejaculatory duct obstruction, retrograde ejaculation, etc.

(6) Sperm morphology: Sperm with normal morphology ≥ 50%, otherwise it may cause infertility.

(7) pH: The normal pH value of semen is 7.2-7.8. A pH value less than 7.2 is seen in ejaculatory duct obstruction or urine contamination; a pH value greater than 7.8 is seen in seminal vesiculitis or old specimens.

(8) Sperm count: It is generally expressed as the number of sperm per milliliter of semen. The normal count is ≥20×106/ml. A count lower than this value indicates too few sperm, which is seen in spermatogenesis disorders caused by various reasons. It may cause low fertility or infertility due to the reduced chance of sperm entering the uterine cavity and fallopian tubes. If the sperm count is greater than 250×106/ml, it indicates too many sperm, which may also cause infertility due to its affected motility.
