How to extract mycoplasma from liquid culture?

Patient's question:

How to extract mycoplasma from liquid culture? First follow-up question: Is that right? Very puzzled

Doctor's answer:

Hello: Semen analysis is generally collected through masturbation.
Suggestions:
① For those undergoing a semen test, it is recommended to avoid sexual activity and strenuous physical labor for 2 to 7 days before the test. Do not drink alcohol or smoke, and ensure adequate rest to eliminate factors that may affect semen quality.
② There are three methods for collecting semen:
The first is masturbation. After obtaining the test requisition form, the patient should ask the urologist for a sterilized cup and collect the semen in the collection room through masturbation. This method is the best.
Another method is to collect semen during sexual intercourse.
③ After collecting the semen, it should be sent to the laboratory immediately. Especially when collected at home, the time taken to reach the hospital should not exceed half an hour. In summer, avoid direct sunlight, and in winter, ensure warmth. Avoid vigorous shaking of the container with semen.
