Sperm can be removed by masturbation, sex, massaging the prostate, or testicular puncture biopsy.
Sperm are usually formed in the testes in the seminiferous tubules and then stored in the epididymis to mature. Sperm can be ejaculated by masturbation, by a couple having sex and reaching an orgasm. Sperm expulsion can also be achieved by anally massaging the prostate gland with a special vibrator or another person’s finger. These three are non-invasive and quick ways.
Second, sperm can also be removed by testicular puncture biopsy, which involves finding the sperm by using a syringe to puncture the epididymal tissue and aspirate the epididymal fluid after local anesthesia. This method is generally used for men with ejaculatory disorders.
