The fertility of men is directly linked to the quality of sperm. This is the reason why among the first tests which are appointed for problems with conception is the spermogram.
The sperm production cycle is long, so many factors can affect sperm quality. 비아그라 구입 is normally within 100 days. During this time period, about 75 days are included for cell division and development in the testes; 20 days to move through the epididymis and about 5 days to feed the vas deferens.
Of these approximately 100 days, the sperm is vulnerable both to its immediate environment also to diet, work patterns and much more.
Work and contact with toxins, pesticides, chemicals, ethylene oxide, vinyl chloride, heavy metals , lead, cadmium, mercury, radioactive elements, X-rays, and various other contaminants have a direct impact on sperm development.
Smoking, excessive use of alcohol, coffee, stimulants and drugs have a serious impact. They have been proven to directly damage the cells from which the sperm originates (spermogonia). Nicotine and tars have a detrimental influence on the fertility of sperm, mainly on sperm concentration, motility and morphology. To this we can add that smoking is connected with poor sperm function in the penetration test, and leads to an increase in leukocytes in the ejaculate.
Prolonged driving and cycling, wearing tight pants and briefs (rather than boxer shorts), hot tubs, showers and saunas, and any exposure to the genitals at high temperatures result in a rise in testicular temperature. Subsequently, heat severely disrupts the procedure of division and maturation of gametes.
Adverse factors include fatigue , mental strain, sedentary lifestyle, overweight, unhealthy eating, prolonged computer use, stress.
Parents of boys with retained testicles in the abdominal cavity can wait up to year following the birth of the child, however in case the testicles do not descend into the scrotum after that, medical intervention is necessary. Other operations for inguinal hernia, varicose veins of the testis (varicocele) are also related to sterility.
Even 2 degrees higher temperature can adversely affect sperm formation . Their concentration will decrease, the amount of the healthy will decrease, and the number of the injured will increase.
In summer, the concentration of sperm, needless to say, decreases. Thus, the sperm content of the ejaculate can drop from 320 million to 250 million.
A warm bath (43-45 degrees) for around 30 minutes each day significantly reduces the concentration of sperm. Tight-fitting briefs, sports shorts or trousers have the same effect.
