以下是保護生育能力的常見方式，根據研究，男性的性欲、勃起功能和性生活頻率會隨著年齡下降，精子的數量和品質也會在35歲後開始衰退。超過40歲的男性，不論伴侶年齡如何，都面臨著早產風險增加的問題。以下是一些常見的影響精子數量和品質的原因：

生活方式和習慣：吸煙、飲酒、濫用藥物、過度飲食、缺乏運動和暴露於有害化學物質（如農藥和化學物質）等不良生活方式和習慣可能對精子數量產生負面影響。

體重和肥胖：過重或肥胖可能導致睪丸過熱，從而影響精子的產生和品質。過多的脂肪也會影響雄激素水平和性功能。

飲食習慣：營養不良或缺乏某些營養素（如維生素C、維生素D、維生素E、鋅、硒等）可能會影響精子的產生和品質。戒菸戒酒並保持規律的生活作息對維護內分泌平衡也非常重要。

壓力：長期或過度的壓力可能對男性生育能力產生負面影響，包括減少精子數量。

睪丸損傷或疾病：睪丸受損或患有某些疾病（如睪丸炎、睪丸扭轉等）可能會影響精子的產生。不要穿太緊的內褲。

環境因素：暴露於高溫環境（如長時間泡在熱水中或長時間處於高溫工作環境中）可能會影響精子的產生。少去蒸桑拿、不要將電腦放在膝上、睪丸的適合溫度在35度左右。

年齡：男性的精子數量通常會隨著年齡增長而下降，尤其是在40歲以後。

遺傳因素：某些遺傳因素可能會影響精子的產生和品質。

總的來說，採取健康的生活方式，包括均衡的飲食、適量的運動、減少壓力、戒菸戒酒等，可以幫助維持正常的精子數量和品質。如果男性有懷疑自己精子數量不足的情況，應該諮詢醫生進行進一步的評估和診斷。

Here are some common reasons that affect fertility, based on research. Men's libido, erectile function, and frequency of sexual activity decrease with age, and the quantity and quality of sperm also decline after the age of 35. Men over 40, regardless of their partner's age, face an increased risk of premature birth. Here are some common factors that can affect sperm quantity and quality:

Lifestyle and habits: Smoking, drinking alcohol, substance abuse, overeating, lack of exercise, and exposure to harmful chemicals (such as pesticides and other toxins) can negatively impact sperm quantity.

Weight and obesity: Being overweight or obese can lead to overheating of the testicles, affecting sperm production and quality. Excess fat can also affect testosterone levels and sexual function.

Dietary habits: Poor nutrition or deficiencies in certain nutrients (such as vitamin C, vitamin D, vitamin E, zinc, selenium, etc.) can affect sperm production and quality. Quitting smoking and drinking alcohol and maintaining a regular sleep schedule are also important for maintaining hormonal balance.

Stress: Long-term or excessive stress can have a negative impact on male fertility, including reducing sperm count.

Testicular injury or disease: Damage to the testicles or certain diseases (such as orchitis, testicular torsion, etc.) can affect sperm production. Avoiding tight underwear is recommended.

Environmental factors: Exposure to high temperatures (such as prolonged soaking in hot water or prolonged exposure to a hot working environment) can affect sperm production. It's advisable to reduce sauna visits, avoid placing laptops on the lap, and maintain a testicular temperature around 35 degrees Celsius.

Age: Men's sperm count typically decreases with age, especially after the age of 40.

Genetic factors: Some genetic factors may affect sperm production and quality.

In summary, adopting a healthy lifestyle, including balanced diet, moderate exercise, stress reduction, and quitting smoking and alcohol, can help maintain normal sperm quantity and quality. If men suspect they have a low sperm count, they should consult a doctor for further evaluation and diagnosis.
