Attention should be paid to sexual life, diet, lifestyle and sperm collection before the sperm test. 1. Sexual life: It is necessary to prohibit sexual life for 3 to 7 days before the sperm test to ensure the concentration and quality of sperm. 2. Diet: Eat a light diet before the sperm test and avoid oily, spicy and stimulating food, so as not to affect the sperm quality. 3. Lifestyle habits: Keep enough sleep and avoid staying up late; pay attention to rest and avoid overwork; prohibit smoking and drinking; avoid emotional fluctuations such as anger and rage. 4. Sperm retrieval: wash and sterilize hands and penis before retrieving semen; do not keep semen at too high or too low a temperature, room temperature is preferred; semen should be sent for examination in time after retrieval. If patients need to check their sperm, it is recommended to go to a regular hospital and operate under the guidance of a doctor to ensure accurate results.
