Sperm: its smell, its color, its composition…

Is the sperm white or yellow? Is it thick or liquid? Does it have a distinctive smell? What to do when its color, smell or consistency changes? Or what is his career in the male body? Answers without embarrassment to embarrassing questions …

How much is ideal sperm?

1.5 to 4.5 ml of sperm (1/2 to 1 teaspoon) are ejaculated, after 2 to 3 days of abstinence, containing an average of 15 million sperm per milliliter. This quantity varies according to the frequency of ejaculations: beyond two ejaculations per day, less than 1 ml are most often produced. Pornographic films distort reality and can disturb men who watch them if they believe it is the reality.

The testosterone level (a male hormone produced by the testes) determines sperm production: if there is a little male hormone, there is less sperm. With age, the output of testosterone decreases and therefore causes a decrease in the amount of sperm (a decline in desire and other symptoms varied). On the other hand, the duration of sexual intercourse does not influence the quantity ejaculated.

The composition of sperm

The sperm contains the spermatozoa, which represent only 1% of the total volume, the seminal fluid produced by the seminal vesicles (65-70%), in which we find sugar, fructose and proteins, the secretions produced by the prostate (15-20%), epididymal-deferential loops (10-12%) and fluid secreted by Cowper’s glands (4-5%), organs under the prostate, which are responsible for.

Sperm contains sugars such as fructose (which feeds sperm), protein, alkaline phosphatase (prostate), carnitine (epididymis), minerals such as zinc, citrate, growth hormone, cells epithelial and white blood cells. The sperm pH is between 7.2 and 7.8 (slightly alkaline).

The color of sperm

The sperm usually has a whitish, transparent or slightly yellow color. This color is variable according to the men and the moments because the proportions of the different components of the sperm can vary. In the case of frequent intercourse, the sperm can become more transparent, and its quantity is smaller. The sperm can be yellow, without being pathological: this color is explained by the oxidation of spermine, a protein responsible for the smell of sperm.

Before any color change, it is advisable to talk to your doctor to plan spermaculture that will check the absence of infection and germs. The collection of sperm is done at home in a bottle, which will then be deposited in the laboratory.

Thus sperm sometimes takes a red color, which usually reflects the presence of blood. Worrying for the man, it is most often not serious and heals alone. A vessel at the level of the seminal vesicles producing seminal fluid may rupture (following infection or trauma, for example). Or in a context of fever, prostatitis can be revoked. In the older man, it is necessary to systematically check that there is no cancer of the prostate because the blood in the sperm can be his first manifestation. Complementary examinations carried out will be an analysis of urine, a spermoculture, a rectal exam.

The sperm trail

The spermatozoa are made by the testes (92 days), they pass in the epididymis where the tail of the flagella is formed, then in the vas deferens, the ejaculatory ducts. They then mix with the seminal fluid produced by the seminal vesicles where the sperm is stored and then with the secretions of the prostate.

The urethra then ejaculates the sperm. In a few seconds, they are in the vagina where they can survive only a few hours because of the vaginal acidity. If there is no egg to fertilize, sperm can stagnate in the mucus in the cervix, up to 72 hours (1 to 5 days) before fertilizing the egg.

The smell and consistency of sperm

All sperms do not have the same taste or smell, which are determined by the different proteins that make it up. Diet also affects the smell and a change in diet effects, so vegetarians are said to have a smoother sperm odor. The scent can put off some women, and a psychological factor can influence them when the penis is associated with urine and dirt.

Variable consistency

At the time of ejaculation, the sperm has a somewhat thick consistency, which liquefies within 30 minutes to facilitate the progression of sperm into the vagina, towards the egg. Sperm has a liquid texture, more or less fluid or thick from one time to another (according to the proportions of seminal fluid and prostatic secretions of semen). It can also contain lumps, without its quality being affected. But this can testify to an infection, which requires permaculture.

In the case of frequent ejaculation, the sperm becomes more transparent and more liquid because the body does not have time to reconstitute a sperm as thick and more opaque. After a few days of abstinence, the sperm becomes thick again and is opaque. If a change in consistency is recent, spermoculture may be prescribed in search of infection.
