If I can’t ejaculate, I guess I’ll never have kids.
There are other options available to become a father.
What Is It?
Male fertility is defined as the ability to father a child.
How does Sperm and Ejaculation work?
- Sperm production starts with the release of hormones (LH and FSH) from the brain. These hormones send messages to the testes to produce testosterone and sperm
- Sperm matures in a 3 month cycle
- Ejaculation is typically how semen (which contains sperm) comes out of the body
- Ejaculation occurs in 2 phases:
- The first phase is called emission or “the loading phase”. During this phase sperm is released from the testicle and mixed with several fluids from different glands, the prostate, and seminal vesicles.
- The second phase is ejaculation proper or the “propulsion phase”. This is when the seminal fluid leaves the body through the urethra. This release can vary in speed, volume, or amount of ejaculatory fluid.
- Semen quality is assessed by looking at how many sperm are present (sperm concentration), what they look like (sperm morphology: i.e. size and shape of their head, body and tail), and what percentage are swimming and moving (sperm motility).
- Even though ejaculation and orgasm often happen together, they are separate processes and one can happen without the other.
Did you know that the sperm that a man ejaculates today was made three months ago? If he was sick or had an infection then, the sperm today may be of lesser quality!
What’s Different Now?
Following spinal cord injury there is a change in the communication system between the nerves, muscles, spinal cord, and brain. This disruption in the communication system can negatively affect a man’s ability to ejaculate.
If you have a complete SCI, chances are the ability to ejaculate will be quite low. If your injury is above T10 (a higher level injury), there is a greater possibility that ejaculation can occur with the use of specialized devices (discussed in more detail in the next section). Lower injuries often require more invasive options.
If you have an incomplete SCI, the ability to ejaculate is difficult to predict and it is often unreliable. This is due to messages being sent from the brain that can interrupt the reflex.
What Can I Do About It?
Explore! Do this with curiosity, but be cautious about your blood pressure getting too high (AD). Also be aware that if you are trying too hard to ejaculate and this is your main goal, it can lead to frustration. If you are having difficulties and would like to learn more about sperm retrieval options, contact the Sexual Health Rehabilitation Service.
Sperm Retrieval Options:
Vibrostimulation: A procedure where a specialized vibrator (that doesn’t look like a penis, just in case that thought crossed your mind!) is applied to the head of the penis to attempt to provoke ejaculation. The vibrators used for this procedure need to be more powerful than ones you would typically find at a sex shop. This is because more stimulation is needed on the penis for your spinal cord to get the message that ejaculation can occur. This procedure is most successful in men with complete injuries above T10. See diagram.
Poor semen quality in men with SCI is due to higher scrotal temperatures from sitting.
There has been no published reports that this is true—attempting to cool your nether regions will be a futile effort!
Electroejaculation: is a procedure that is used when vibrostimulation fails. It is most commonly used for sperm retrieval when the spinal cord injury is below T10. This procedure can occur either in the clinic (i.e. if there is no anal sensation: complete injury) or in the operating room (i.e. when anal sensation is present; incomplete injury). This procedure involves the insertion of a foley catheter that blocks the bladder neck so seminal fluid comes forward out of the penis, rather than back into the bladder. A rectal probe, delivers an electrical current to the prostate through the rectum. This procedure is quite effective in producing an ejaculate for reproductive purposes.
Surgical Sperm Retrieval: Sometimes, when vibrostimulation and electroejaculation have been tried and the results have been poor (little to no sperm), surgical sperm retrieval is attempted. This procedure is done by placing a needle into the testicle or surrounding structures to remove sperm cells. The number of sperm cells retrieved by this procedure is considerably less than other methods. The image beside highlights the structures that sperm can be extracted from.
Semen Quality: We know that semen quality changes post SCI. This has to do with changes to the seminal fluid, however, the exact causes for these changes are still being researched. Typically, men with SCI have good sperm concentration (number of sperm), however, sperm motility (the amount the sperm move/swim) and what they look like (morphology) are most commonly affected.
What do I need to know?
It is important to know the resources in your local area. A consultation with a medical professional before trying something like vibrostimulation (VS) is strongly recommended. Autonomic dysreflexia (AD) commonly occurs with vibrostimulation, therefore, it is not recommended that VS be done at home without medical advice.
It is also important to know that sperm retrieval is the first step in determining your fertility potential. Once sperm is obtained, it needs to be sent to a lab for an analysis to determine semen quality. The quality of sperm will determine the most appropriate method for insemination (aka baby making!).
There have been over 200 babies born in the last 30 years of the Vancouver Sperm Retrieval Clinic!
Equip yourself with the information provided in this chapter and understand your own injury. Even if you aren’t ready for to start a family right now, this information can give you direction when you are ready. This information may also be helpful when discussing future plans with a partner.

Despite changes to ejaculation after SCI, becoming a father is still possible. Being familiar with the resources and options available to you can be important when you decide you would like to start a family. It is common for men to want to understand their fertility potential even before they are in a relationship. You can start this process at any time, even if you aren’t planning to start a family right away. Knowing your options, and knowing your body now, is a great way to feel more sexually confident.
