Does lifestyle affect fertility?

Patient's question:

Detailed medical condition and consultation purpose: Which lifestyle habits affect fertility

Doctor's answer:

Hello: The following lifestyle habits affect fertility;
1) Frequent hot baths: Sperm production requires an environment that is 1℃-1.5℃ lower than normal body temperature (37℃). Studies show that immersing in 43℃-44℃ warm water for 20 minutes for 3 consecutive days can reduce sperm density below 10 million/mL in individuals with normal sperm density, and this effect can last for 3 weeks. The "warmth contraception method" recently researched is based on this principle. Therefore, frequent and prolonged hot baths are not suitable for infertile patients with low sperm count and poor motility. However, hot baths 1-2 times a week for short durations are generally not an issue.
2) Poor nutrition and selective eating: Sperm production requires raw materials, so spermatogenesis is closely related to nutritional levels. This doesn’t necessarily mean eating turtle or eel. However, consuming more lean meat, eggs, fish, and vegetables to ensure adequate protein, vitamins, and trace element intake is essential. People with selective eating habits are often prone to certain nutritional deficiencies.
3) Depression and excessive fatigue: Depression and fatigue can affect sexual function and spermatogenesis.
4) Excessive cycling, motorcycling, tricycle riding, and horseback riding, etc.: This often leads to chronic strain and congestion in the prostate and other accessory glands, affecting their function and exacerbating chronic inflammation, thereby impairing fertility.
