PESA
At Eva IVF & Women’s Centre, we believe that male subfertility should never be a barrier to parenthood. For men dealing with obstructive azoospermia—a condition where sperm production is normal but cannot reach the semen due to blockages—PESA (Percutaneous Epididymal Sperm Aspiration) offers a minimally invasive, effective solution.
This simple outpatient procedure allows us to retrieve healthy, motile sperm directly from the epididymis, making it possible for you and your partner to conceive using ICSI (Intracytoplasmic Sperm Injection). PESA is fast, virtually painless, and a proven alternative to surgical sperm retrieval methods.
What is PESA?
PESA (Percutaneous Epididymal Sperm Aspiration) is a procedure that involves aspirating sperm from the epididymis (a small tube at the back of the testicle where sperm mature and are stored) which is non-surgical and needle-based.
It is primarily performed in cases of:
• Obstructive azoospermia due to vasectomy, injury, or congenital absence of the vas deferens
• Post-infection scarring of reproductive ducts
• Failed vasectomy reversal
• Sperm retrieval for ICSI or cryopreservation
💡 It is often the first choice for sperm collection in men with normal sperm production but blocked reproductive tracts.
Who Should Consider PESA?
PESA is an excellent option for:
✔ Men diagnosed with obstructive azoospermia
✔ Couples planning IVF with ICSI treatment
✔ Individuals with a history of vasectomy or failed reversal
✔ Men seeking sperm retrieval for fertility preservation
✔ Those looking for a less invasive option compared to open testicular biopsy
💡 This technique is particularly effective when sperm production is intact but cannot be ejaculated naturally due to a physical blockage.
How PESA Works – A Step-by-Step Guide
1. Initial Evaluation
• Hormonal testing (FSH, LH, testosterone)
• Scrotal ultrasound (if needed) to assess anatomy
• Fertility goals and IVF/ICSI planning were discussed
2. Procedure Day
• A fine needle is inserted into the epididymis through the scrotal skin and a fluid containing sperm is aspirated and sent to the IVF lab for processing
• Sperm are examined for motility, count, and structure
⏱️ Duration: 15–30 minutes
🏥 No hospital stay required – same-day discharge
💡 The collected sperm can be used immediately for ICSI or frozen for future IVF cycles.
Benefits of PESA
🌟 Minimally Invasive and Quick – No cuts or stitches involved
🌟 Comfortable Recovery – Patients can resume their normal activity within 24 hours
🌟 High Success Rate in sperm retrieval from obstructive cases
🌟 Repeatable – Can be performed again when needed
🌟 No Major Surgery Required – Ideal for men preferring a non-surgical approach
💡 When paired with ICSI, PESA opens the door to biological fatherhood for men with complete ejaculatory obstruction.
Success Rates and Fertility Outcomes
📊 Based on clinical data and our expertise at Eva IVF:
✔ 95–98% sperm retrieval success in obstructive azoospermia
✔ Fertilization and pregnancy rates comparable to IVF with ejacuted sperm
✔ Consistent quality of sperm retrieved across multiple cycles
✔ Higher patient satisfaction
💡 With proper partner evaluation and embryo culture, couples can achieve pregnancy with just a few motile sperm.

💡 Our fertility specialists will recommend the best method based on your condition and conception plan.
Post-Procedure Guidelines
✔ Mild soreness is expected; pain relief medications are provided
✔ Avoid intense physical activity or intercourse for 2–3 days
✔ Use ice packs and supportive underwear to reduce discomfort
✔ Schedule follow-up visit to review sperm analysis and IVF planning
✔ Sperm can be frozen for future cycles if pregnancy is not immediate
