What is TESA / MESA?
💡 TESA (Testicular Sperm Aspiration) and MESA (Microsurgical Epididymal Sperm Aspiration) are surgical sperm retrieval techniques used when no sperm is present in the ejaculate. Retrieved sperm is used with ICSI to achieve fertilisation.
TESA and MESA are surgical procedures used to retrieve sperm directly from the male reproductive tract. They are used when no sperm is present in the ejaculate. In TESA, a fine needle is inserted into the testis to extract sperm-containing tissue. In MESA, sperm is taken from the epididymis under a microscope — giving a higher yield and better quality. Both procedures are used for men with azoospermia, ejaculatory dysfunction, or failed vasectomy reversal. Retrieved sperm is used with ICSI to achieve fertilisation.
🇮🇳 India Context: TESA / MESA is widely assessed and treated across major Indian fertility centres including Chennai, Mumbai, Bangalore, Delhi, and Hyderabad.
When is TESA / MESA used?
- Obstructive azoospermia — vasectomy, absent vas deferens, epididymal blockage
- Non-obstructive azoospermia — impaired sperm production (micro-TESE preferred)
- Ejaculatory dysfunction — retrograde ejaculation, spinal cord injury
- Failed vasectomy reversal
Risks and considerations
⚠️ Haematoma (most common), infection, testicular atrophy (rare), failure to retrieve sperm (especially in non-obstructive azoospermia). Performed under local or general anaesthesia. Always discuss risks with your fertility specialist before treatment.
