Watery ejaculation is not necessarily azoospermia. This is because azoospermia is a phenomenon in which no sperm is found to exist in the semen after a semen examination. Ejaculation as thin as water may be due to frequent ejaculation, vesiculitis, lowered androgen levels, partial urine mixing during ejaculation, etc. It does not mean that there is a problem with sperm quality. In this case, it is recommended to abstain from sex for 3-7 days and then go to the hospital for semen examination. If it is confirmed that the semen does not contain sperm inside, it is azoospermia, mostly caused by genetics, endocrine diseases, blocked vas deferens, testicular insufficiency, etc. The specific cause should be identified and treated in cooperation with the doctor. In daily life, it is recommended that men avoid standing for long periods of time or wearing tight pants, and also try not to stay in a radioactive, high temperature, toxic gas environment for long periods of time to avoid affecting fertility.
