U jerk off at home, and store your sperm into a bottle and hand over to the clinic within an hour.
After around several weeks, u go to the Family Planning Association Clinic to see your report, and the nurse will have a brief explanation of the report to u. And finally, u will be bought to a female doctor's office, and she will explain the report once again, and ask u to take off your plant, and touch your organ (both upper and lower) to exam. It lasts only around 20 sec.
