Men's waist size determines sperm quality, is it true?

It is not true that a man's waist size determines sperm quality. A

man's sperm quality is influenced by many factors, such as genetics, lifestyle, environmental factors, reproductive health, etc. Waist size mainly reflects the accumulation of abdominal fat, which has a certain relationship with individual health status, but it has no decisive relationship with sperm quality. Waist size does not directly determine sperm quality. For men, if you want to determine their sperm quality, you should pass a professional semen test to obtain accurate information.
