Thirty years ago, men with normal fertility had about 60 million sperm in 1ml of each ejaculation. Now, even with normal fertility, the amount of sperm per milliliter has dropped to 15 million. With less sperm, fertility will naturally decline.
Male friends don't understand. They feel that their physical quality is very good, and they are also very strong. How can sperm become less?
Six sperm "killers" in life
"Killer" No. 1: tobacco and alcohol
Foreign studies have shown that compared with non-smokers, the semen quality indicators of smokers are lower and the sperm deformity rate is also higher. Moreover, carcinogens such as nicotine in tobacco can also cause testicular atrophy and sperm morphology changes.
Alcohol also has a direct effect on testicles. Research shows that people with chronic alcoholism will suffer from testicular atrophy, leading to a decline in semen quality.
"Killer" No. 2: Obesity
There is an aromatase substance in human adipose tissue, which can convert male hormone into estrogen. There are more aromatase in obese people, which increases the female hormone in men and leads to hypogonadism, thus affecting the quality and quantity of sperm.
On the other hand, too much fat around the testis makes the scrotum warm up, which directly affects the sperm activity.
"Killer" No. 3: take a hot bath
Frequent sauna or hot bath can kill sperm.
Male scrotum is very sensitive to temperature. Once the temperature exceeds the normal temperature, it will affect sperm quality. The temperature of hot springs is generally high. If the soaking time is too long, the sperm will be "heated to death", which will easily cause infertility over time.
It is recommended that men take a hot bath or hot spring and control the time, which should not exceed 15 minutes at a time.
"Killer" No. 4: Frequently drink coke
Coke contains a certain amount of caffeine, which also has a certain impact on sperm.
Some male friends even regard Coke as a daily drink. Drinking it for a long time will also affect blood sugar and endocrine.
"Killer" No. 5: Drugs
Hormones, antibiotics and anticancer drugs can also damage the male sexual function, causing the quality and quantity of sperm to decline.
Generally speaking, the greater the dose and the longer the course of treatment, the more serious the impact on fertility.
At present, there is a flood of sexual health products on the market, some of which even contain sex hormones. These substances can affect the normal spermatogenic ability of the testicles. The unborn should be careful when taking them.
"Killer" 6: radiation
High dose of radiation will change the structure of testicle tissue and increase the sperm deformity rate.
The mobile phones and computers we use everyday will emit radiation, which will affect sperm.
Therefore, it is suggested that male friends should try to reduce their exposure to radiation and take precautions.
