During Your Procedure
You will be given general anesthesia to put you to sleep during the procedure. A catheter tube will be placed in your bladder to drain out your urine. A solution will then be put into your bladder to lower the acid level. This protects any sperm that may pass into your bladder when you ejaculate.
Your doctor will place a probe into your rectum. A mild electrical current will be delivered through the probe. This is repeated every few seconds and slowly increased until you ejaculate.
All of your semen will be collected. This includes the semen from your penis and any that may have passed into your bladder. The semen will be analyzed under a microscope. If no sperm are found, another procedure called testicular sperm extraction (TESE) may be performed. This involves collecting the sperm directly from the testes. This will only be done if you consented for this beforehand.
Once the semen has been collected, the probe and catheter will be removed. The semen will be placed into vials and delivered to the Sperm Bank of New York, where it will be analyzed. The semen will be transferred to their affiliated sperm bank in New Jersey for freezing and storage. The address of the sperm bank where your semen will be stored is:
