TESA & PESA in Kolkata — Surgical Sperm Retrieval for Azoospermia

What is TESA & PESA Surgical Sperm Retrieval Kolkata?

TESA involves inserting a fine needle into the testis under local anaesthesia to aspirate sperm-containing tissue. PESA aspirates sperm from the epididymis — the coiled structure behind the testes — and is used for obstructive azoospermia. For non-obstructive azoospermia (where sperm production is impaired), micro-TESE uses a microscope to find the tiny pockets of active sperm production within the testes — offering the highest retrieval rate available.

Who Needs This?

TESA/PESA is recommended for men with obstructive azoospermia (blocked vas deferens, post-vasectomy), non-obstructive azoospermia (Sertoli cell only, hypospermia), ejaculatory dysfunction, failed vasectomy reversal, and any case where sperm cannot be obtained through ejaculation.

The Process

• 1Step 1: Comprehensive evaluation — FSH, LH, testosterone, karyotype, Y-chromosome microdeletion testing
• 2Step 2: Procedure selection — TESA, PESA, or micro-TESE based on diagnosis
• 3Step 3: Procedure under local anaesthesia or short IV sedation
• 4Step 4: Embryologist immediately examines retrieved tissue for viable sperm
• 5Step 5: Sperm used directly for ICSI or cryopreserved for future cycles
• 6Step 6: Post-operative rest 2–3 days; partner's IVF cycle coordinated simultaneously
