There is no special-effective way to improve sperm quality the day before sperm collection, but abstinence, life and diet adjustments, etc. are needed before the test. 1. Abstinence: To check semen routine, it is recommended to abstain from sex for 3~7 days before the test. 2. Dietary adjustments: live a regular life, go to bed early and get up early to ensure enough good sleep, quit smoking and drinking, and eat a diversified diet for balanced nutrition.

For example, genitourinary infections, you can choose sensitive antibiotics, such as cephalosporin, levofloxacin, etc., if it is due to varicose veins of the spermatic cord, you need to take surgical treatment.
