TESA / PESA: Complete Guide

TESA (Testicular Sperm Aspiration) and PESA (Percutaneous Epididymal Sperm Aspiration) are fertility procedures used to collect sperm directly from the male reproductive tract when sperm is not present in the semen. PESA retrieves sperm from the epididymis, while TESA retrieves sperm from the testicular tissue. The collected sperm is usually used for IVF with ICSI, where a single sperm is injected into each egg.

These procedures are most commonly recommended in men with azoospermia, particularly obstructive azoospermia, and in selected cases of non-obstructive azoospermia. In Indian fertility practice, they are typically performed as outpatient or day-care procedures under local anaesthesia, sedation, or short general anaesthesia depending on the centre and patient comfort.

TESA or PESA may be advised when a semen analysis shows no sperm and the issue is not correctable with medicines or surgery alone. Common situations include blocked vas deferens, previous vasectomy, absent vas deferens, infection-related obstruction, congenital problems, or after failed ejaculation-based sperm retrieval methods. It may also be considered in some men with severe sperm production problems when sperm is not found in the ejaculate.

The choice between TESA and PESA depends on the cause of azoospermia, hormone profile, testicular examination, ultrasound findings, and prior treatment history. A fertility specialist may also advise genetic testing, hormone tests, and counselling before the procedure to estimate the chance of obtaining usable sperm and planning IVF/ICSI accordingly.

The process starts with a fertility consultation, semen analysis, and evaluation of the cause of azoospermia. On the procedure day, the area is cleaned and numbed with local anaesthesia or light sedation. In PESA, a fine needle is placed into the epididymis to aspirate fluid containing sperm. In TESA, a needle is inserted into the testis to aspirate tissue or fluid, which is then examined in the lab for sperm.

If sperm are found, they may be used fresh for ICSI or frozen for future cycles. The procedure usually takes less than an hour. Most men can go home the same day with simple pain relief, ice packs, rest, and instructions to avoid heavy activity for a short period. Follow-up is important to review pain, swelling, and the next IVF/ICSI steps.

The biggest benefit of TESA/PESA is that it allows biological fatherhood for men who otherwise have no sperm in the ejaculate. When paired with ICSI, even very small numbers of sperm can be used to fertilise eggs. This makes the procedures especially valuable in obstructive azoospermia, where sperm production is usually intact but blocked from reaching the semen.

Another advantage is that the procedure is minimally invasive and generally quick, with little downtime compared with surgery. In many Indian centres, sperm can be cryopreserved for future cycles, reducing the need to repeat retrieval. For couples using HomeIVF-supported fertility care, this can simplify scheduling, counselling, diagnostics, and the IVF/ICSI journey in a coordinated way.

TESA and PESA are generally safe, but like any procedure they can cause temporary pain, swelling, bruising, or a feeling of heaviness in the scrotum. Less commonly, there may be minor bleeding, infection, or discomfort lasting several days. Most side effects are mild and improve with rest, scrotal support, and medicines prescribed by the doctor.

Important but uncommon risks include failure to obtain enough sperm, especially in non-obstructive azoospermia, where testicular sperm production may be limited. Very rarely, repeated procedures can cause more tissue trauma. Patients should seek medical review if they develop fever, increasing redness, severe pain, or significant swelling after the procedure.

Success rates depend on the cause of azoospermia, the technique used, lab expertise, and the couple’s overall fertility factors. In obstructive azoospermia, sperm retrieval rates with PESA/TESA are typically high, often in the range of 80-95% in experienced Indian fertility centres. In non-obstructive azoospermia, the retrieval rate is much more variable and may be roughly 20-60% depending on the underlying diagnosis and whether micro-TESE is considered.

It is important to note that sperm retrieval success is not the same as pregnancy success. Pregnancy and live birth rates depend on female age, egg quality, embryo quality, uterine factors, and IVF/ICSI lab performance. For patient counselling, doctors usually discuss both retrieval likelihood and the expected IVF outcome together rather than as a single number.

The cost of TESA or PESA in India varies by city, hospital type, anaesthesia, lab processing, and whether sperm is used fresh or frozen. Typical procedure-only pricing is usually lower than a full IVF cycle, but the overall treatment cost rises when ICSI, medicines, and freezing are added. Many patients should budget for both the retrieval and the IVF/ICSI cycle.

Actual pricing can differ widely across India, so couples should ask for a written estimate that includes medicines, scans, lab fees, and follow-up visits.

HomeIVF helps couples move through male-factor fertility treatment with less confusion and more coordination. From initial consultation to semen analysis, hormone testing, procedure planning, and IVF/ICSI coordination, HomeIVF can streamline the journey so patients know exactly what happens next. This is especially useful when sperm retrieval and egg retrieval need careful timing.

For Indian families, convenience matters: HomeIVF can support test booking, doctor coordination, counselling, and treatment planning while keeping the process patient-friendly and transparent. When sperm retrieval is recommended, HomeIVF helps couples understand whether TESA or PESA is more suitable, what the realistic success expectations are, and how to prepare for the next step in treatment with confidence.
