What are the precautions for sperm testing?

Sperm examination is a very important examination for male reproductive health, because the current phenomenon of infertility seriously affects couples and families. For male sperm examination, it is necessary to abstain from sexual intercourse for 2 to 7 days in the early stage, and pay attention to the cleanliness of hands when collecting sperm.

1. Before collecting semen, you must stop having sex for 2 to 7 days, and you must not masturbate or have nocturnal emissions. You should also abstain from smoking and drinking, and avoid taking any medication that may affect spermatogenesis.

2. The best time to collect semen is in the morning. Wash your hands, genitals, and especially the glans penis with warm water before collecting semen. You can use masturbation or electric massage ejaculation to induce ejaculation.

3. Semen is discharged in a certain order. The first part comes from the prostate, epididymis and umbilicus, accompanied by a large number of sperm, and the last part comes from the seminal vesicle. Therefore, the whole semen should be collected without missing any part, especially the first part. Because the first part of semen is easy to lose, semen cannot be collected by extracorporeal ejaculation.

4. The container for semen should be clean, sterile and dry, and the temperature of the container should be the same as room temperature before semen collection. The bottle should not be too large, but the mouth of the bottle should not be too small to prevent semen from being ejaculated out of the bottle. A label should also be affixed to record the name and time of semen collection.

5. In cold weather, semen samples should be kept warm and placed in the pocket of underwear. They should not be tilted or inverted, and should be sent to the laboratory within 1 hour if possible.
