These are all various methods to extract sperms in the testis in patients with azoospermia.
What Are TESA and TESE?
TESA (Testicular Sperm Aspiration) and TESE (Testicular Sperm Extraction) are minimally invasive human sperm collection process methods performed when sperm is not present in the ejaculate.
- TESA Procedure: A fine needle is inserted into the testis to aspirate tissue containing sperm.
- TESE Procedure: A small incision is made to remove testicular tissue directly, typically used when TESA yields no sperm.
Both procedures are often followed by TESA IVF or ICSI, where the retrieved sperm fertilizes an egg in the lab to achieve pregnancy.
Human Sperm Collection Process Explained
The human sperm collection process at Kanaa Fertility Centre is safe, step-by-step, and patient-focused:
- Consultation & Hormonal Evaluation: Assessment of fertility status, medical history, and need for biopsy or sperm retrieval
- TESA Procedure: Performed under local anesthesia with a thin needle to collect sperm cells
- TESE Procedure: Involves a small incision to retrieve tissue under anesthesia
- Biopsy Surgery & Analysis: Extracted tissue is examined microscopically to identify healthy sperm
Sperm Freezing or Use: Collected sperm is used immediately for TESA IVF or cryopreserved for future fertility treatment
Who Needs TESA and TESE?
These sperm retrieval techniques are recommended for:
- Men with obstructive or non-obstructive azoospermia
- Cases where previous IVF cycles failed due to lack of viable sperm
- Men with genetic or testicular abnormalities that prevent ejaculation
- Patients undergoing biopsy surgery to assess fertility potential
