Sex and relationships after Focal Therapy
Whatever your age, we know that having sex is an important part of many peoples’ relationships, and that the prospect of losing this due to impotence can be distressing. Although you are having the treatment, any kind of procedure can affect your partner and friends. We advise all our potential patients to discuss their options with someone they trust.

How does prostate treatment impact sex and relationships?
97% of the men we’ve treated are able to get and maintain erections normally, or with the help of pills or other medication. Research from Prostate UK shows that 76% of men who receive whole gland treatment for prostate cancer experience erectile dysfunction.
After focal therapy, you’ll still be able to produce sperm and semen, although you may find you produce less than you did before. We are delighted that some of our patients have gone on to have children after treatment.
After focal therapy, most men keep their erections and sexual desire, although some notice small changes. The large majority of our patients continue to enjoy a normal sex life after treatment. We are pleased that men often report confidence in their intimacy returning quickly.
After focal therapy, men recover their erections within a few weeks. Around 20% find that tadalafil helps during recovery. At one year after treatment, over 95% of our patients report normal erectile function.
Anejaculation means not producing semen during orgasm, (Dry Orgasm) and occurs after surgery for prostate cancer. After focal therapy, this side effect is very rare, and most men continue to ejaculate, although sometimes with less volume.
Prostate cancer’s impact on partners and relationships
Communication challenges: Couples may struggle to talk openly about changes in intimacy
Partner’s emotional response: Partners may feel confused, rejected, or unsure how to help.
Need for adaptation: Couples often need to redefine what intimacy looks like, exploring new ways to connect physically and emotionally.
Strain vs. growth: While some relationships experience strain, others grow stronger through shared coping and emotional closeness.

“the man having the radical prostatectomy historically will have some discussion about [the] impact on your sex life…that can be quite shocking for the patient to hear and nothing else is discussed.”

Questions to ask your doctor or nurse
Are You a Good Candidate for HIFU (High-Intensity Focused Ultrasound)?
- Your cancer is intermediate risk (usually Gleason 3+4 or 4+3).
- The cancer is localised (hasn’t spread outside the prostate).
- Your PSA is under 15–20 ng/mL.
- You are expected to live at least 8–10 more years.
- The cancer is in one main spot and small enough to target.
Note: HIFU is not usually used for very low-risk or very high-risk cancer. It aims to treat the cancer while keeping side effects like incontinence or erection problems low.
"I had the HIFU procedure with Tim Dudderidge and was very happy with the results... I have absolutely no incontinence and I'm fully sexually active without any side effects."
“Focal HIFU treats cancer with lower side effects.”
HIFU is available at the Focal Therapy Clinic in the UK. It is one of the leading centres for focal therapy, including HIFU, NanoKnife, and Cryotherapy. The team includes top urologists like Mr. Tim Dudderidge, Mr Marc Laniado, Mr Raj Nigam and Mr Alan Doherty who have treated over 2,000 patients successfully.
Patient quote: "I had the HIFU procedure with Tim Dudderidge and was very happy with the results." – Graham Pipe, FTC HIFU patient.HIFU targets only the cancer, not the whole prostate. This means fewer side effects like leaking or erection problems compared to surgery or radiotherapy. NanoKnife is also precise and may preserve erections slightly better, especially in tricky cancer locations.

HIFU can be safely repeated if the cancer comes back in the treated area. Studies show about 15 to 20% of men may need a second round, and it usually works well. Follow-up scans and biopsies help decide if another treatment is needed.
Urologist quote: “Focal HIFU lets us hit the cancer without harming the rest of the prostate.” – Mr. Raj NigamFor men with intermediate-risk, localized prostate cancer, HIFU has a success rate of about 88% at 5 years—meaning no need for surgery, radiation, or further treatment. Side effects are usually mild: 2% need a pad for leaks for a short time, and 90%+ men keep erections, especially if function was good before treatment.

- PSA tests every 3 months for the first year
- MRI scan at 12 months
- Biopsy only if the MRI scan indicates an area of concern
- Regular checks for urinary or sexual function
This helps catch any signs of cancer coming back early.
