Micro-TESE significantly improves sperm retrieval success rates for men with severe testicular failure while minimizing long-term tissue damage and testosterone drop. 4. MESA (Microsurgical Epididymal Sperm Aspiration) Best Suited For: Obstructive Azoospermia.
A fine needle is inserted directly through the skin of the scrotum into the epididymis to gently extract fluid. Because it does not require a surgical incision, it has a rapid recovery time but is only viable if sperm production is normal and a physical blockage is the only issue. 4. Testicular Sperm Aspiration (TESA)
This is the gold standard for severe cases of non-obstructive azoospermia, providing the highest chance of finding sperm while preserving testicular tissue. Anesthesia: General anesthesia. 4. MESA (Microsurgical Epididymal Sperm Aspiration) Hegre - Danny - Medical Sperm Extraction
This highly targeted approach maximizes the chances of finding sperm in failing testicular tissue while minimizing damage to the surrounding blood vessels and healthy structures. What to Expect: The Patient Journey
Their story demonstrates the importance of: A fine needle is inserted directly through the
In men with hypogonadotropic hypogonadism (low FSH and LH), hormonal therapy with gonadotropins may improve sperm production before surgery.
Voluntary sterilization via vasectomy. Non-Obstructive Azoospermia (NOA) Testicular Sperm Aspiration (TESA) This is the gold
Sperm retrieved directly from the epididymis or testes are often structurally immature or have limited motility compared to ejaculated sperm. Because they cannot swim effectively to penetrate an egg on their own, medically extracted sperm must be paired with . During an IVF-ICSI cycle:

This article focuses purely on the clinical, evidence‑based practice of medical sperm extraction. If you are looking for a specific physician named Daniel Hegg, there is a Dr. Daniel Hegg who specializes in emergency medicine, but no direct connection to sperm retrieval. For accurate medical information, always rely on peer‑reviewed sources and direct consultation with a reproductive urologist.
