What are the main causes of sperm survival rate?

The sperm survival rate is mainly influenced by the following factors: 1. Lifestyle and dietary habits: Poor eating habits, such as nutritional deficiencies or imbalances, along with sedentary behavior, staying up late, and excessive fatigue, may lead to reduced sperm quality and lower survival rates. 2. Environmental factors: Exposure to radiation, high temperatures, and other environmental conditions may interfere with normal spermatogenesis, causing abnormal sperm morphology or functional impairments, thereby reducing sperm survival rates. 3. Genetic factors: Certain genetic disorders or gene mutations may affect sperm development and viability, negatively impacting sperm survival rates. 4. Disease factors: Conditions such as varicocele, reproductive tract infections, and endocrine disorders can lead to abnormalities in sperm morphology and function, affecting sperm survival capacity.
