Doctor Nguyen Van Phuc, Department of Andrology, 108 Central Military Hospital, said that male infertility is an increasingly common condition, causing many men to lose confidence, affecting family happiness. Among the many causes of infertility in couples, 30% of infertility cases come from men. Proactively learning about the causes of male infertility will help men quickly prevent themselves and have quick intervention measures.
The causes of male infertility can come from many causes such as illness, problems with intercourse or lifestyle.
Pathological causes include varicocele, infection, ejaculation problems or blockage of the vas deferens.
In addition, there are causes that directly affect male reproductive function.
According to statistics from the World Health Organization (WHO), 1/3 of the world's population over the age of 15 smokes. Smoking has a direct impact on the reproductive function of both men and women. Studies show that men who smoke have lower sperm counts and sperm quality than men who do not smoke.
The longer you smoke and the more cigarettes you smoke (more than 20 cigarettes a day), the higher your risk of infertility. In addition, smoking is also a cause of erectile dysfunction in men.
Drinking too much alcohol affects some male hormones (Testosterone, LH, FSH) and hinders sperm development. Toxins in alcohol and beer can damage the DNA structure of sperm, increasing the risk of malformations and reducing the quality and quantity of sperm.
According to Dr. Nguyen Van Phuc, scientists say that fried foods contain acrylamide, which reduces sperm quality and can cause some cancers. In addition, fried foods contain a type of unsaturated fatty acid. This substance directly affects male hormones, disrupting sperm production in men.
Drugs, especially marijuana, directly affect sperm. Marijuana impairs sperm motility, making it difficult for them to reach the egg for fertilization. Drug use can damage sperm DNA, increasing the risk of birth defects and fertility problems.
One of the causes of infertility given by Dr. Nguyen Van Phuc is wearing tight pants and bathing in water that is too hot. This habit inadvertently increases the temperature of the testicles and reduces sperm quality. Therefore, men should not soak in hot tubs for too long and wear loose, airy underwear. Or stress, frequent tension can affect the hormones Testosterone and LH, which affects sperm quality. In addition, psychological problems cause sexual dysfunction such as erectile dysfunction, premature ejaculation, and difficulty ejaculating.
Being overweight or obese also greatly affects male fertility. Excess fat around the abdomen and thighs can increase the temperature of the scrotum, where sperm is produced, causing sperm quality to decline.
Healthy men who slept less than 6 hours had weakened sperm count. Sperm from sleep-deprived men had lower survival rates.
