Infertility is increasingly common in modern society. Children represent not only the continuation of family lineage but also serve as the emotional foundation for couples. The rising number of male infertility cases distances patients from the prospect of family happiness.Male infertility is defined as the inability to conceive after three years of unprotected intercourse due to factors attributable to the male partner. The WHO recently updated its definition to include couples who have failed to conceive after at least 12 months of regular, unprotected intercourse. Recent studies indicate that male obesity also impacts fertility. So why does obesity lead to infertility in men?What should be noted in daily life?
Why does obesity cause infertility?
In obese men, the entire genital area is surrounded by fat, impairing heat dissipation. Prolonged exposure to high temperatures severely hinders sperm production. Additionally, obesity disrupts endocrine function, lowering testosterone levels while increasing estrogen, which easily leads to infertility.Some men may not appear visibly overweight but are medically classified as obese—this group faces the highest risk. Because they don't look overweight, they often overlook this issue, failing to recognize the impact of their diet and lifestyle habits. This can lead to persistent infertility without a clear diagnosis. A simple medical checkup can reveal whether weight is excessive, which may be a hidden cause of endocrine dysfunction.Many men mistakenly believe weight gain is a sign of prosperity, or that being too thin is undesirable. This mindset is fundamentally flawed.
What precautions should men take to prevent infertility?
Avoid excessively hot baths or showers.
Sperm requires a stable temperature of 34°C to 35°C for optimal development. Water temperatures exceeding this range can pose hidden risks.For instance, sauna temperatures can reach 70°C to 80°C (158°F to 172°F)—more than double the typical bath temperature—which severely impairs sperm growth or causes excessive "dead sperm," leading to infertility. Medical research on male infertility reveals that some men experience sperm failure due to testicular temperatures 2°C to 3°C (3.6°F to 5.5°F) higher than normal.Therefore, young men should exercise caution with saunas. For regular bathing, water temperatures around 34°C are ideal.
Changing Unhealthy Habits
Avoid excessively greasy foods, as they can dampen libido. Additionally, minimize exposure to toxic substances in daily life—for instance, let dry-cleaned clothes air out for several days before wearing, as dry-cleaning solvents may impair male sexual function.
Protect Your Reproductive Organs
The testicles are highly sensitive organs that function optimally at temperatures about 1°C lower than body temperature. Elevated temperatures can impair sperm production. Avoid activities that raise testicular temperature, such as prolonged bicycle riding, hot baths, or wearing tight jeans.
Maintain Genital Hygiene
Genital hygiene isn't just for women—it's equally important for men. Proper cleaning and hygiene of the reproductive organs can help prevent penile cancer.
Men must take charge of their own health, which is also a sign of responsibility. In daily life, all men should cultivate good habits and have a clear understanding of their family responsibilities.This is especially true in marital relations—only a healthy sex life can foster a harmonious and fulfilling family life.
Men should pay closer attention to their physical condition in daily life. Male infertility can directly impact a family's happiness. For men, the consequences of infertility are significant. We hope the above information proves helpful.
