In infertile couples, the cause is the husband accounting for 30%. There are many factors that affect fertilization. In particular, the most important is the quality of the mother's eggs and the fertilizing ability of the husband's sperm.
Men produce millions of sperm a day, while women only have about 300-400 eggs ovulated in a lifetime. External factors (such as temperature) can affect sperm. Sperm take about 75 days to mature, damage to them has long-term effects on your fertility.
Here are 10 factors that can affect male sperm:
1. Temperature rise
Human testicles cannot function properly if they do not have a lower temperature than the rest of the body. Fortunately, men have testicles located outside the abdomen and have a temperature 2*C lower than their body temperature. If testicular temperature is elevated, sperm production may stop. Once there, sperm can be affected for several months in terms of quantity, motility and shape.
Hot bath: Just 30 minutes in a hot tub or Jacuzzi can temporarily affect sperm production. However, this effect is reversible but must wait at least 3 months, as sperm take a long time to mature.
2. Fever
High fever has the same effect as a hot bath. Sperm can be reduced by up to 35% after a fever.

3. Laptop
When using a laptop, you should put the laptop on the table. Laptops can increase the temperature of the scrotum with close contact.
4. Underpants
Wearing tight, tight underwear for a long time also affects sperm production.
5. Varicose veins of the testicles
About 15% of men have a varicocele, usually in the left scrotum. Varicose veins disrupt blood flow, increase testicular temperature due to increased blood volume in the testicular veins. Although there is no clear evidence yet, doctors hope surgery can improve sperm quality.

6. Mobile phone
Men should not keep their phones in their pockets to limit their exposure to phone radiation.
7. Obesity
Obesity is associated with increased production of the Hormone Estrogen, which reduces sperm count, reduces libido and causes infertility.
8. Tobacco, alcohol and drugs
Alcohol affects sperm production and quality. Smoking affects sperm motility, damaging sperm DNA.
Drugs also affect sperm count and quality.
