Overworked, long-distance cycling
Perineum and scrotum squeeze a long time in the state , on the one hand affect the secretion of the prostate and seminal vesicles ; On the other hand , testicular ischemia in a long time , and even minor injuries. These can affect semen quality . toggle clamps
Adverse psychological state
Psychological pressure is too large, too long in a state of tension , depression, anxiety , pessimism and sadness , etc. can lead to decline in semen quality , spermatogenic dysfunction, pregnancy rate. pipe clamps
Improper diet
Rich diet can provide all kinds of sperm to generate the necessary protein, calcium , zinc, selenium, phosphorus, magnesium , VitA and VitE other nutrients. If the partial eclipse , it is possible that the lack of these essential substances , leading to reduced sperm count and quality . Long zinc / selenium can lead to reduced male fertility , reduced sperm count , malformation rate increases, an increased risk of fetal malformations . Zinc rich foods include walnuts, liver, soybeans, vegetables , dried kelp, peanuts , shrimp , squid and so on. Studies have proven that proper zinc selenium can improve sperm motility , sperm morphology improve and increase fertility . hose clamps
Sedentary
Sedentary is currently the most common bad habits . Sedentary than 8 hours per day , for one year or more, the apparent decline in semen quality . Last more than three years , with poor semen quality is about 46%. Same study also found that lifestyle changes , abandon sedentary, increasing physical activity , exercise every day ( or brisk walking , jogging , swimming, ball games , etc. ) conducive to sperm quality improvement . bessey clamps
Smoke
Cigarette smoke contains so spermatogenesis mutagenic mutagenic substances, can not only cause damage to genetic material in cells , but also through the blood - testis barrier affect germ cell maturation and proliferation , resulting in increased sperm DNA strand breaks , sperm deformity rate increased. best dildos
Alcoholism
Ethanol on sperm density , motility, viability , morphology and fertilizing capacity have obvious damage effect. The extent of damage and started drinking age, alcohol consumption and duration are closely related. Long-term heavy drinking can lead to alcoholism, cause testicular atrophy, decreased libido , sperm deformity rate increases, the total number and density decreases. Chronic alcoholism is less than 80% of sperm viability , sperm deformity rate can be as high as 83%. Started drinking before age 18 significantly harm caused by alcohol even after the age of 18 adults . black dildos
Ethanol may indirectly by affecting the synthesis of sex hormones affect sperm , or direct damage to testicular seminiferous tubules seminiferous epithelium cells, the gonad degenerative changes occur , spermatogenic dysfunction or even atrophy. Ethanol also has a direct effect on sperm , which can cause sperm morphology changes include head off, middle neck swelling , tail curled and sperm agglutination . Alcohol -induced hypothalamic - pituitary - gonadal axis testicular dysfunction, can lead to testicular atrophy , sperm start, differentiation, development and the number , shape and function abnormalities. ejaculating dildos
Improper sexual frequency
Appropriate frequency of intercourse not only beneficial to both men and women 's physical health and mental balance, but also to improve semen quality, increase conception opportunities. However, too frequent sexual intercourse , sperm density and will reduce the number of affected spouses pregnancy, rather than , as some mistakenly believe that a friend of " plowing , no gain " ; course, frequency of sexual intercourse is too small, will also affect the spouse of pregnancy ; addition , long- time different room or do not ejaculate , sperm motility and fertilizing ability will decline, not abstinence longer the better the quality of sperm . WHO recommended 2-7 days of abstinence semen quality can best response at this stage the true male fertility . vibration vaginal
