Two days of abstinence to check sperm is inaccurate. For patients who need semen analysis, the minimum abstinence should be 5-7 days for the best results. Because two days of abstinence, the sperm generated has not been effectively transported to the seminal vesicles, the sperm examined in this case, sperm vitality, sperm count, sperm viability, and forward motion, are inaccurate. For this situation, it is easy to lead to errors, it is recommended to always abstain from sex for 5-7 days, and then retain semen, which should be sent to the laboratory within half an hour to be tested, so that the test results will be the most accurate and will not be inaccurate.
