What Is Testicular Rejuvenation?

The testicles make sperm and the hormone testosterone. When sperm production is very low or absent, the cause is often a problem within the testicle itself (called testicular failure or non-obstructive azoospermia), and there are few treatments that address it directly.

“Testicular rejuvenation” refers to investigational, regenerative procedures that aim to improve the environment inside the testis so that any remaining sperm-forming cells work better. The most studied approach is an injection of your own platelet-rich plasma (PRP) — a growth-factor-rich concentrate prepared from a small sample of your blood — into the testes.

What it is not: testicular rejuvenation is not a proven cure for infertility, not a testosterone booster, and not an anti-ageing or performance treatment. It cannot guarantee sperm production, a successful sperm retrieval or a pregnancy. Our doctors will discuss this openly before you decide anything.

According to the World Health Organization , about 1 in 6 adults experience infertility, and male factors contribute in a large share of couples — which is why both partners should always be evaluated.

Why Sperm Production Falls

A cause is found in many men, though not all. Common causes include:

• Varicocele — enlarged veins around the testicle that raise its temperature; often treatable.
• Genetic conditions — such as Klinefelter syndrome (47,XXY) or Y-chromosome microdeletions.
• Undescended testicles in childhood, even if corrected by surgery.
• Past infections — mumps orchitis or genital infections.
• Chemotherapy, radiation or testicular injury/torsion.
• Hormonal disorders — low LH/FSH from the pituitary, thyroid or prolactin problems.
• Testosterone or anabolic steroid use — these switch off the body’s own sperm production.
• Lifestyle factors — smoking, heavy alcohol use, obesity, recreational drugs and prolonged heat exposure.
• Unexplained (idiopathic) — no cause identified despite full testing.

Signs You Should Get Evaluated

• Not conceiving after 12 months of trying — sooner if the female partner is over 35.
• An abnormal semen analysis — very low count, poor movement or no sperm.
• Small, soft or painful testicles, or a swelling or heaviness in the scrotum.
• Failed sperm retrieval (TESE/mTESE) in the past.
• Symptoms of low testosterone — reduced desire, tiredness, low mood or reduced facial and body hair.
• History of cancer treatment, testicular surgery or injury.

Many men have no symptoms at all and only discover the problem through a semen test, so testing early avoids lost time.

How We Evaluate Male Fertility

Before any regenerative option is even discussed, we look for treatable causes:

Testicular Rejuvenation Compared With Other Options

Proven treatments always come first. Regenerative options are considered only for carefully selected men:

What Does the Research Say?

Micro-dissection testicular sperm extraction (micro-TESE) remains the main approach for men with non-obstructive azoospermia, but some men have no retrievable sperm even after repeated attempts and have no other established option. Intratesticular PRP has been proposed for this group.

Reviews describe the early findings as promising but limited: most human data come from small, uncontrolled case series, alongside animal studies. In one published case series of men with earlier failed sperm retrieval, sperm were found after PRP in roughly 16–28% of men depending on how many prior attempts they had had, and some couples achieved pregnancy. Because there was no comparison group, we cannot tell how many of these results were due to PRP itself.

Put simply: it may help a small number of men, we cannot yet predict who, and larger controlled trials are still needed. We would rather tell you this clearly than promise more than the evidence supports.

How the Procedure Works at StemRx

If, after evaluation and counselling, you and your doctor decide to go ahead, the pathway is:

Step 1 — Consultation and Counselling

Your specialist reviews your history, reports and goals, treats any correctable cause first, and explains realistic outcomes, alternatives, costs and the investigational nature of PRP.

Step 2 — Baseline Tests and Informed Consent

Semen analysis, hormone tests, ultrasound and genetic tests (where indicated) are completed. Both partners receive written information, and consent is taken in writing.

Step 3 — Preparation of PRP

A small sample of your own blood is drawn and spun in a centrifuge to concentrate the platelets. Because it is your own blood, the risk of allergy or rejection is very low.

Step 4 — Injection

Under local anaesthesia or light sedation, the PRP is injected into the testes with a fine needle, sometimes guided by ultrasound. It is a short day-care procedure, and the protocol may involve one or more sessions.

Step 5 — Recovery and Waiting Period

You go home the same day, with advice to avoid strenuous activity for a short period. Because sperm take roughly 2–3 months to develop, any change is assessed after this interval.

Step 6 — Re-Testing and Fertility Planning

Semen analysis and hormones are repeated. Depending on the result, your team plans natural attempts, sperm retrieval with ICSI, or other options, and coordinates with your partner’s IVF care.

Possible Risks and Side Effects

• Pain, swelling and bruising of the scrotum — common for a few days.
• Blood collection (haematoma) inside the scrotum — uncommon; more likely with blood-thinning medicines.
• Infection — rare, prevented by sterile technique and, where needed, antibiotics.
• Injury to the testicle or its blood supply — very rare, but possible with any needle procedure.
• Unknown long-term effects — long-term safety data for intratesticular PRP are limited.
• Disappointment — a result of no improvement is possible, and support is available.

Call us immediately for fever, increasing pain, rapidly growing swelling, redness or a hard, tense scrotum after the procedure.

Supporting Male Reproductive Health Every Day

• Avoid testosterone and anabolic steroids if you wish to father a child — they suppress sperm production, sometimes for a long time.
• Stop smoking, vaping and recreational drugs, and keep alcohol low.
• Reach a healthy weight and stay physically active.
• Keep the testes cool — avoid saunas, hot tubs and long periods with a laptop on the lap.
• Eat a balanced diet — vegetables, fruit, nuts, whole grains and adequate protein.
• Manage stress and sleep — poor sleep and chronic stress can affect hormones.
• Be careful with supplements — discuss any product with your doctor; avoid those promising to “boost testosterone” or “restore fertility”.
• Consider sperm freezing before cancer treatment or surgery that may affect fertility.

Frequently Asked Questions

Can testicular rejuvenation cure male infertility?

No. It is an investigational approach that may help some men with severe testicular failure, but it does not guarantee sperm production or pregnancy. Outcomes vary widely, and many men see no change.

Who is a suitable candidate?

Mostly men with non-obstructive azoospermia or very severe low sperm counts, often after an unsuccessful sperm retrieval, in whom treatable causes have already been addressed. Your specialist decides after a full evaluation.

Will it increase my testosterone or improve sexual performance?

It is not a testosterone or performance treatment. If you have symptoms of low testosterone, that needs its own evaluation — and note that testosterone replacement can reduce sperm production, so it must be planned carefully if you want children.

Is the procedure painful?

It is done with local anaesthesia or light sedation, so pain during the procedure is usually minimal. Soreness or swelling for a few days afterwards is common and can be managed with simple measures your doctor will advise.

How long before we know if it worked?

Sperm production takes about 2–3 months, so re-testing is usually planned after that period. Your doctor will explain the schedule for your protocol.

Will I still need IVF-ICSI?

Almost always, yes. Even when sperm appear or can be retrieved, they are usually used with ICSI. PRP is intended to improve the chance of finding sperm, not to replace assisted reproduction.

Is it safe?

Using your own blood keeps allergy and rejection risk low, and serious complications appear to be uncommon when the procedure is done by trained specialists. However, long-term safety data are limited, which is why counselling and informed consent are essential.

Will my visit be confidential?

Yes. Your reports and consultations are handled privately, and you can choose whether your partner attends.
