With the full opening of the “two-child policy”, most men of child-bearing age are excited and excited, and a large number of them have already taken action. However, most of them choose to do some basic tests to see if they are still capable of having a second child before they prepare for pregnancy. In this case, a semen test is the most basic, convenient and affordable test. Although a semen routine is very simple, don’t underestimate this simple test, as there is a lot of knowledge hidden in it. The following are some of the issues that need to be taken into account when doing a routine semen test. The actual fact is that you will find a lot of people who don’t know that they need to be abstinent to do the semen routine, and there are often some patients who have sperm in the morning and then come to do the semen routine during the day. Dr. Yuan tells you that this is not possible, as abstinence is usually required for 3-7 days for a semen routine, and I usually advise patients to abstain for 5 days. If the abstinence time is too short, it may result in low semen volume or low density, which will often make the test results inaccurate. If the abstinence time is too long, the dead sperm and abnormal sperm in the semen will increase significantly, and the test result will also be inaccurate. I believe that there are many ways to collect semen, but this is not the case. This is not possible, because condoms usually contain spermicidal substances, which will make the test results inaccurate. We generally recommend that semen be collected by masturbation, which will not affect the quality of semen and will also ensure complete collection. 3. What should be used to send semen for testing after collection? It is true that semen is not solid and cannot be taken by the patient directly by hand for sending it for examination. Hospitals generally use sterile containers with large openings (usually provided by the MDI room of the laboratory), and doctors usually tell patients to go to the laboratory to collect them after issuing them with a checklist. 4. Time to open the checklist Since the hospital laboratory collects semen specimens before 10:30 a.m. and 4:30 p.m., so in order not to delay you more, please ask the doctor to issue a semen checklist when you arrive at the clinic (you can only ask for the checklist in advance, this does not mean that you can jump the queue to see the doctor).
