Percutaneous Epididymal Sperm Aspiration (PESA) — Cost, Top Hospitals & Success Rates | MyMedicPlus

Percutaneous Epididymal Sperm Aspiration (PESA) is a minimally invasive urological procedure used to retrieve sperm directly from the epididymis in men who cannot produce sperm in their ejaculate due to obstructive azoospermia. It is performed under local anaesthesia and takes approximately 15–30 minutes as an outpatient procedure.

During PESA, a fine needle is inserted through the scrotal skin into the epididymis — the coiled tube behind each testicle where sperm mature and are stored. Negative pressure is applied to aspirate epididymal fluid containing sperm, which is then assessed by an embryologist in real time. Retrieved sperm are used immediately or cryopreserved for future use in in vitro fertilisation with intracytoplasmic sperm injection (IVF/ICSI).

PESA was first described in the early 1990s and rapidly became the preferred first-line sperm retrieval method for men with obstructive azoospermia because of its simplicity, low cost, and minimal morbidity compared to open surgical retrieval techniques. It does not require an operating room — the procedure can be performed in a clinic or fertility centre procedure room.

The retrieved sperm may have slightly reduced motility compared to ejaculated sperm, but when used with ICSI (where a single sperm is injected directly into each egg), fertilisation and pregnancy rates comparable to ejaculated sperm can be achieved.

PESA is primarily indicated for men with obstructive azoospermia — a condition where sperm are produced normally in the testes but cannot reach the ejaculate due to a physical blockage. Common underlying causes include:

• Congenital bilateral absence of the vas deferens (CBAVD) — the vas deferens is absent from birth, most commonly associated with cystic fibrosis gene mutations; sperm are produced but cannot be transported
• Post-vasectomy azoospermia — men who have had a vasectomy and wish to father children without vasectomy reversal; PESA offers an alternative path to biological parenthood
• Epididymal obstruction — blockage of the epididymis due to prior infection (chlamydia, gonorrhoea), trauma, or inflammation
• Failed vasectomy reversal — when vasovasostomy or vasoepididymostomy has not successfully restored natural sperm transport
• Ejaculatory duct obstruction — blockage at the ejaculatory duct level preventing sperm from entering the urethra
• Post-surgical scarring — previous inguinal hernia repair, orchidopexy, or other pelvic surgery causing inadvertent vas deferens damage

PESA is not suitable for men with non-obstructive azoospermia (where the testes fail to produce sperm), as the epididymis will not contain viable sperm in this condition. These patients require testicular sperm extraction (TESE or micro-TESE).

Candidacy for PESA is determined through a systematic male fertility evaluation:

• Confirmed azoospermia — two semen analyses showing complete absence of sperm (WHO 2021 criteria)
• Normal testicular volume and FSH levels — serum FSH within the normal range and testicular volume ≥15 mL on ultrasound strongly suggest obstructive rather than non-obstructive azoospermia
• Documented obstruction — clinical history (vasectomy, CBAVD, prior epididymo-orchitis) or physical examination confirming likely obstructive cause
• Partner assessment complete — female partner should have undergone ovarian reserve testing and basic fertility workup before committing to ART
• Genetic counselling completed where appropriate — men with CBAVD must undergo cystic fibrosis mutation testing; their partners should also be screened before proceeding, as offspring carry CF carrier risk
• No active scrotal infection or coagulopathy — these are contraindications to needle aspiration

When obstructive versus non-obstructive azoospermia cannot be distinguished clinically, a diagnostic PESA can be performed; absence of sperm would prompt proceeding to testicular biopsy or micro-TESE.

PESA is one of several sperm retrieval techniques. Understanding the options helps patients and clinicians choose the most appropriate method:

PESA (Percutaneous Epididymal Sperm Aspiration)

Performed under local anaesthesia (1–2% lidocaine spermatic cord block). A 21–23 gauge butterfly needle connected to a 20 mL syringe is inserted through the scrotal skin into the epididymis head (caput). Gentle negative pressure aspirates epididymal fluid. The embryologist examines the sample immediately. If sperm are found, the procedure is complete; if not, the needle is repositioned or the contralateral epididymis is sampled. The procedure takes 15–30 minutes with minimal discomfort. Sperm retrieval rate: 70–90% in confirmed obstruction.

MESA (Microsurgical Epididymal Sperm Aspiration)

An open surgical procedure performed under general or spinal anaesthesia using an operating microscope. The epididymis is directly visualised, and individual tubules are dissected and incised to retrieve fluid. MESA yields larger numbers of higher-quality sperm than PESA and allows cryopreservation of multiple vials, but requires a skilled microsurgeon and operating room. Preferred when large quantities of sperm are needed or when PESA has failed.

TESA (Testicular Sperm Aspiration)

Needle aspiration directly into the testicular parenchyma. Used when epididymal aspiration fails or is not possible. Yields testicular sperm (less mature than epididymal sperm) suitable for ICSI. Can be performed percutaneously or under direct vision.

Micro-TESE (Microsurgical Testicular Sperm Extraction)

The gold-standard technique for non-obstructive azoospermia. Under the operating microscope, areas of active spermatogenesis are identified and selectively harvested. Sperm retrieval rates in NOA: 40–60%. Requires general anaesthesia and specialist microsurgical expertise.

PESA vs Vasectomy Reversal

For post-vasectomy patients, vasectomy reversal (vasovasostomy) offers the possibility of restoring natural fertility if the partner is young and fertile. However, reversal success rates decline with time since vasectomy, and reversal is not always feasible. PESA with ICSI is often preferred when the couple desires immediate ART, if the female partner has her own fertility issues, or if reversal has a low expected success rate.

PESA offers several compelling advantages over alternative sperm retrieval methods:

• Minimally invasive — a single needle insertion through intact scrotal skin; no incision, no sutures required
• Outpatient procedure — performed under local anaesthesia in a clinic or procedure room; patients go home within hours
• Rapid recovery — most men return to normal activities within 24–48 hours; minimal post-procedural pain managed with over-the-counter analgesia
• High success rate in obstructive azoospermia — sperm retrieval rates of 70–90% are consistently reported in properly selected patients
• Cost-effective — significantly less expensive than open microsurgical techniques (MESA) or testicular extraction (micro-TESE), and requires no operating room
• Repeatable — PESA can be repeated on the same epididymis or the contralateral side if initial sampling is insufficient; epididymis typically regenerates stored sperm
• Excellent ICSI outcomes — fertilisation rates with PESA-retrieved sperm in ICSI are comparable to those achieved with ejaculated sperm (65–75% fertilisation per egg)
• Sperm cryopreservation — surplus sperm can be frozen for future IVF cycles, reducing the need for repeated procedures

PESA is generally safe, but patients should be aware of potential complications:

• Haematoma — the most common complication; scrotal bruising or haematoma formation occurs in approximately 2–5% of cases; most resolve spontaneously with supportive care (ice, scrotal support, rest)
• Pain and discomfort — mild scrotal aching for 24–48 hours is expected; severe or persistent pain is unusual and should prompt medical review
• Infection — epididymo-orchitis following needle aspiration is rare (<1%); prophylactic antibiotics are administered in some protocols
• Epididymal scarring — repeated PESA procedures can cause fibrosis within epididymal tubules, potentially reducing sperm yield in subsequent attempts; this is a consideration for patients who may need multiple retrieval cycles
• Vasovagal reaction — transient vasovagal episodes (dizziness, faintness) during or after the procedure occur in a small minority of patients; managed with positioning and observation
• Failed sperm retrieval — in approximately 10–30% of attempts (including cases where obstruction was not confirmed), no viable sperm are found; this necessitates escalation to MESA, TESA, or micro-TESE
• Sperm quality concerns — epididymal sperm are less mature than ejaculated sperm and must be used with ICSI; natural insemination or standard IVF is not possible with PESA-retrieved sperm

Recovery from PESA is typically straightforward:

Immediate Post-Procedure (Hours 1–4)

Patients rest in the clinic for 30–60 minutes after the procedure. A scrotal support is applied. Ice packs are recommended for the first 4–6 hours to reduce swelling and bruising. Oral analgesics (paracetamol or ibuprofen) are prescribed for pain management. The embryologist reports sperm retrieval results before the patient leaves.

First 48 Hours

Scrotal support should be worn continuously. Heavy lifting, vigorous exercise, and sexual activity are avoided. Mild bruising and swelling are expected and resolve within a week. Patients should monitor for signs of haematoma (rapidly increasing swelling, significant pain) or infection (fever, increasing redness, discharge).

Sperm Processing and Use

Aspirated sperm are assessed for motility and morphology. If used fresh (same day), they are processed for immediate ICSI. Excess sperm are cryopreserved using controlled-rate freezing with cryoprotectant. Survival rates after thawing PESA sperm are generally 50–70%.

IVF/ICSI Cycle Coordination

When PESA is planned alongside a fresh IVF cycle, the procedure is typically coordinated with the female partner's egg retrieval (oocyte pick-up) on the same day. The embryologist uses PESA sperm for ICSI immediately after retrieval. Pregnancy rates per embryo transfer are 30–50% depending on female age and embryo quality.

Follow-Up Visit

A review appointment at 1–2 weeks confirms complete wound healing and resolution of any haematoma. Further fertility follow-up depends on IVF cycle outcome.

PESA costs are influenced by several variables:

• Procedure fees — the PESA procedure itself (excluding IVF) ranges from USD 500–2,000 in most countries; in India, costs are typically USD 200–600 at accredited fertility centres
• Anaesthesia type — local anaesthesia (standard) is less expensive than IV sedation; general anaesthesia significantly increases cost
• Embryologist and laboratory fees — sperm processing, motility assessment, and cryopreservation add USD 300–800
• IVF/ICSI cycle cost — PESA is only one component; a full IVF/ICSI cycle (stimulation, monitoring, egg retrieval, fertilisation, embryo transfer) costs USD 3,000–15,000 depending on country
• Cryopreservation storage — annual storage fees for cryopreserved sperm range from USD 200–600 per year
• Country and centre — fertility treatment costs vary widely; India (USD 2,000–5,000 for full IVF+PESA), Thailand (USD 4,000–8,000), versus USA (USD 15,000–25,000) or UK (USD 8,000–14,000)
• Repeat cycles — if the first ICSI cycle does not result in pregnancy, subsequent frozen embryo transfer (FET) cycles add cost; budgeting for 2–3 cycles is advisable
• Insurance coverage — fertility treatment coverage varies; some national health systems (UK NHS, Israel) cover limited cycles; most private insurers in the US exclude ART

Depending on the cause of azoospermia and patient preferences, alternatives to PESA include:

• Vasectomy reversal (vasovasostomy or vasoepididymostomy) — microsurgical reconnection of the vas deferens; success rates of 40–90% depending on time since vasectomy; allows natural conception without ART; preferred by some couples over repeated IVF cycles
• MESA (microsurgical epididymal sperm aspiration) — open microsurgical technique yielding higher-quality and greater quantities of sperm; preferred when large sperm reserves are needed for multiple IVF cycles or when PESA yields are inadequate
• TESA (testicular sperm aspiration) — direct testicular needle aspiration; used when PESA fails or the epididymis is not accessible; testicular sperm are less mature but functional with ICSI
• Micro-TESE — for non-obstructive azoospermia; microsurgical testicular mapping to find focal areas of spermatogenesis
• Donor sperm insemination (DI) — using sperm from an anonymous or known donor eliminates the need for surgical retrieval; suitable for couples who do not require a genetic link to the male partner
• Adoption or surrogacy — non-biological paths to parenthood for couples who prefer to avoid invasive medical treatment
