1. When semen can't be taken with drugs before examination, penis massage can be done with soft soap or paraffin oil, and the specimens are collected in sterile test tubes; Semen can also be collected through condoms or sexual intercourse interruption, but the amount collected in this way is often small.
You can't collect semen with condom. Condoms are mostly treated by vulcanization process, which has spermicidal effect, thus affecting the accuracy and motility of sperm counting. In addition, when the condom is pulled down from the penis, it is easy to make semen flow out of the condom, which affects the quantity of semen.
3. Restrain sexual intercourse, not prohibit sexual intercourse. Under physiological conditions, the number of sperm will increase significantly within 4 days after sperm discharge. After 4 days, the number of sperm will gradually increase. For long-term abstinence, the number of dead sperm and the abnormal rate of sperm will increase. Therefore, it is generally advocated to abstain from sex for about 4 days for semen examination.
4, semen inspection should pay attention to heat preservation. Generally speaking, the temperature of semen transportation and inspection should be kept between 25-37 degrees Celsius. When the weather is too cold, doctors should ask patients to keep semen samples close to their bodies to avoid damaging sperm. On the contrary, if the weather is too hot, it will also cause semen damage.
