This information will help you prepare for your sperm collection by electroejaculation (EEJ) at Memorial Sloan Kettering (MSK).
EEJ is a procedure to collect sperm for analysis, freezing, and storage. It is for men who are not able to collect sperm by masturbating to ejaculation. During the procedure, a mild electric current is used to cause an ejaculation while you are asleep.
After your procedure, your semen will be brought to the Sperm Bank of New York, where it will be analyzed. After it is analyzed, it will be transferred to their affiliated New Jersey sperm bank for freezing and storage. The address of the sperm bank:
Some sperm banks may offer less expensive storage fees. Speak with your healthcare provider if you are interested in having your sperm moved to a different sperm bank or if you have any other questions.

Parking at MSK is available in the garage on East 66th Street between York and First Avenues. To reach the garage, turn onto East 66th Street from York Avenue. The garage is located about a quarter of a block in from York Avenue, on the right-hand (north) side of the street. There is a pedestrian tunnel that you can walk through that connects the garage to the hospital. If you have questions about prices, call 212-639-2338.
There are also other garages located on East 69th Street between First and Second Avenues, East 67th Street between York and First Avenues, and East 65th Street between First and Second Avenues.
Please arrive at the main building of MSK at 1275 York Avenue between East 67th and East 68th Streets. Take the M elevator to the 2nd floor. Enter through the glass doors and check in at the desk.
Once you arrive at the hospital, doctors, nurses, and other staff members will ask you to state and spell your name and date of birth many times. This is for your safety. People with the same or similar names may be having procedures on the same day.
You will receive general anesthesia to put you to sleep during the procedure. A catheter (thin, flexible tube) will be placed in your bladder to drain out your urine. A solution will be put into your bladder through the catheter to lower the acid level. This protects any sperm that may pass into your bladder when you ejaculate.
While you are asleep, 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 or if the sperm do not move well, 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 to it before your procedure.
Once the semen has been collected, the probe and catheter will be removed.Back to top
