Testicular torsion is one of very few genuine emergencies in urology, and it is defined by time more than by anything else. The spermatic cord twists, the blood supply to the testicle is cut off, and the tissue begins to die. Everything about the outcome depends on how quickly the blood supply is restored. Within roughly the first six hours the testicle is usually saved. Beyond twelve, the odds fall sharply. Beyond twenty-four, they are poor.
That is the whole of the clinical picture, and it is why this is worth knowing before it happens. Torsion is most common in adolescents and young men, though it can occur at any age, and it frequently begins during sleep or after minor activity for no identifiable reason. The men most likely to experience it are, as a group, the least likely to attend a hospital for pain.
What It Feels Like
The typical presentation is sudden, severe pain in one testicle, often waking a young man from sleep or beginning abruptly during the day. Nausea and vomiting are common and are a meaningful part of the picture rather than an incidental detail. The affected testicle often sits higher than the other and may lie at an unusual angle. The scrotum may become swollen and red over the following hours.
Two variations cause most of the delay. First, the pain sometimes begins in the lower abdomen or groin rather than the testicle itself, and gets attributed to a strain or a stomach problem. Second, torsion can be intermittent — the cord twists and untwists, producing episodes of severe pain that resolve on their own. Those episodes are a warning, not a reprieve, and a man who has had them is at higher risk of a torsion that does not untwist.
Not all sudden scrotal pain is torsion. Epididymitis, a torted testicular appendage and trauma all present similarly, and some of those are far less urgent. The difficulty is that the distinction cannot be made reliably by the man experiencing it, by a phone conversation, or by waiting to see what happens overnight. That is the entire reason the rule is simple.
What to Do
Sudden severe testicular pain should be assessed at an emergency department immediately, at any hour. Not the next day, not after a shift, and not after seeing whether it settles. If the pain resolves on the way there, the assessment is still worth completing, because intermittent torsion is a recognised pattern.
Nothing should be eaten or drunk on the way, since surgery may be needed quickly. Bringing someone to drive is sensible, because the pain is often severe.
What Happens in Hospital
Assessment is clinical first. A doctor examines the testicle, checks the cremasteric reflex, and forms a judgement about how likely torsion is. Doppler ultrasound, which shows blood flow, is frequently used, but a strong clinical suspicion takes priority over waiting for imaging — and in that situation men are sometimes taken to the operating room without a scan. That is appropriate, not excessive.
Surgery involves untwisting the cord and assessing whether the testicle recovers colour and blood flow. If it does, it is fixed in position with sutures so it cannot twist again, and the other testicle is usually fixed at the same time, because the anatomical predisposition is generally present on both sides. If the testicle is not viable, it is removed. A man with one healthy testicle retains normal hormone production and, in most cases, normal fertility — a point worth knowing, since fear of losing a testicle is itself sometimes what delays men from going in.
Recovery from the procedure is usually straightforward, with a short period off heavy work.
Dr. Raymond Nash assesses testicular and scrotal conditions at Grande Prairie Men’s Medical Clinic, including follow-up after torsion and investigation of recurrent or unexplained scrotal pain. Non-urgent appointments can be made at gpmm.clinic or (587) 416-8296; sudden severe testicular pain should go directly to an emergency department.
