Patient's question:
What are the precautions to be taken when checking semen and sperm? I have had sex with my wife many times, but she hasn't shown any signs of pregnancy yet. Could this be related to my sperm? I want to check if there is any problem with my sperm. What are the precautions to be taken when checking semen and sperm?Doctor's answer:
Hello, please pay attention to the following points:1. Sperm collection must be performed only when in good health.
2. Abstain from sexual activity for 3-5 days before collection. A period that is too short (e.g., 2 days) may lead to reduced sperm density and semen volume, while a period that is too long (e.g., >7 days) may result in decreased sperm motility. During abstinence, smoking, alcohol consumption, and the use of drugs that affect sperm production (e.g., sex hormones) should be avoided.
3. The best method for collecting semen is masturbation. Intercourse for ejaculation may lead to the loss of highly motile sperm and the inevitable mixing of vaginal secretions, which can reduce sperm motility.
4. Before collection, wash your hands and genitalia, especially the glans penis, with warm water. The environment should be quiet and free from distractions. The best time for collection is in the morning, and it is recommended to do so at a specialized hospital.
5. The collection container should be sterile, clean, and dry. The temperature of the container should be the same as the room temperature. The opening of the container should not be too small to prevent semen from spilling out. The capacity of the container should not be too large. Condoms should not be used for collection, as the latex in condoms and lubricants or talcum powder on them can affect sperm motility. Additionally, semen sticking to the condom may affect the measured volume of semen.
6. After collection, the semen container should be stored at around 37°C. Avoid tilting the container after collection and send it for testing immediately. Strive to have the test completed within a short time, generally no more than 2 hours. Prolonged storage or extreme temperatures (too low or too high) can affect sperm motility.
