6 things to know about sperm
1-sperm is getting fat
False between 2 AND 6 Millilitres of sperm are issued during each ejaculation. It’s the equivalent of a tea spoonful. Sperm is composed of minerals such as potassium, magnesium and trace elements such as zinc. It contains proteins, carbohydrates, fat. No need to weigh on the balance: the energy value of each ejaculate is estimated at 15-30 calories.
2-food influences its taste
True and false on the question, specialists don’t agree. One (like gérard tixier sperm says that the taste of seed is clean to every man. Others consider that abuse of red meat, dairy, garlic or coffee can give it a more acid flavour. A not so silly hypothesis, judge the french sexologists in their book the mechanics of men, since food acts on the smell of perspiration, saliva or breast milk.
3-sperm die as soon as they are in the air free
Fake out of the body, they can survive several hours. As long as they bathe in seminal liquid. In contact with the free air, the sperm dries fast, which causes the death of sperm. Inside the body of the woman, in other words in a “welcoming” environment, they can survive between three and five days nestled in the cervical mucus at the entrance of the cervical pass.
4-we can be allergic to sperm
True but it’s very rare. The first cases of sperm allergy were described in Germany in 1958. This reaction is reflected in irritation, even pain, swelling of the genital zone or itching. We often confuse these symptoms with signs of cystitis, herpes or itchy, hence a difficulty to ask the diagnosis. In the most severe cases, sperm allergy can cause generalized urticaria, anaphylactic shock or angioedema edema.
5-sperm is made in the testicles
True and false the head of the sperm is made in the testicles. But the flagellum (the tail) is in the epididymis, organ attached to the testicle. As soon as they are mature, the spermatozoa go up the channel canal to the vesicles that produce the seminal liquid, and stay stored there. They mix to this liquid to give the sperm. At the time of ejaculation, the sperm leaves the vesicles and crosses the rod to be propelled outside at a speed of about 45 km / h.
6-obesity night to sperm
True a study from the university of Melbourne established the end of August a correlation between paternal obesity and delay in the development of the foetus. Skeptics would like to know that these tests were made in vitro on mice. Remains that it is not the first time a study concludes with a similar result. In 2011, French researchers had shown that sperm concentration in seed decreased by 20 % in obese people compared to men with normal weight.
