Semen examination is one of the most important tests that reflect male fertility. According to statistics, the incidence of infertility in China is about 10%, and the trend is increasing year by year, while infertility and infertility caused by male factors is already close to 50%. We found in our outpatient work that many patients are unable to remove semen by themselves due to various factors, and some patients can remove semen even if they can, but the semen removed is a small amount or spilled part of it, so the accuracy of the test is low. Because the semen at the beginning of the ejaculation has the highest density and the best quality, if the whole specimen is not caught, it will affect the results of the semen test, which in turn will directly affect the clinical diagnosis and treatment. The best semen specimen to be used for testing is the one obtained in a state that resembles sexual intercourse, so that the semen specimen can truly reflect the patient’s semen condition. Our department has newly purchased an advanced semen collection equipment – “Weili brand” computerized automatic semen collection instrument, which allows you to easily take out semen in a state similar to sexual intercourse, and can collect all the semen without any leakage or spillage of the specimen. There is no leakage or spillage of the specimen. For those who have difficulty with sperm retrieval, you can ask your doctor for a sperm collector to help you easily retrieve your sperm.
