First time patients usually need to check semen, before coming over need to pay attention to several issues: 1, abstinence 2-7 days, not too short, not too long; 2, semen examination time is, Monday to Friday, 8:00-11:30 am, 1:30-3:00 pm Saturday morning 8:00-10:00; 3, semen report card the second day to take (Friday, Saturday the next Monday to take); 4, if brought from home, not more than 30 minutes, the container should not be toxic effect. If you bring it from home, do not take more than 30 minutes, keep it at 36.5°, the container should not have toxic effects. I wish you all a healthy baby.
