There is no accurate clinical data on the chances of pregnancy with low sperm motility, which depends on the cause of the disease. Low sperm viability is mainly related to factors such as poor environment, irrational use of medication and reproductive system infections, and the chances of conception vary for different reasons. 1. Poor environment: For example, living in a high-temperature, radioactive environment for a long time may lead to low sperm viability. If the spermatozoa viability is only mildly low, after improving the environment in time, the spermatozoa viability will gradually increase, thus achieving the goal of fertility. 2. Unreasonable use of medication: For example, prolonged use of antimicrobials, tranquilizers and other medications may affect male fertility and lead to low spermatozoa viability. After some patients stop taking medication, the sperm viability will gradually increase and there is a chance of pregnancy. However, a small number of patients may not be able to return to normal after stopping the medication. 3. Reproductive system infections: for example, epididymitis, seminal vesiculitis, vasculitis, etc. These diseases are more complicated, and in mild cases, through timely treatment, normal fertility can be achieved; however, in some patients, the condition is serious, which may result in varicose veins expanding abnormally, making the treatment more difficult, and the testicular function will be reduced, which makes it difficult to get pregnant. If the sperm viability is found to be low, the cause should be analyzed as soon as possible, and then regular treatment should be carried out, which can alleviate the condition and improve fertility.
