When a semen analysis indicates a zero sperm count (azoospermia) or severe male factor issues, PESA & TESA Procedures in Kenya offer a clinical solution. These are specialized forms of sperm aspiration for male infertility designed to retrieve viable sperm directly from the reproductive tract. These methods are essential for men who have a physical blockage preventing sperm from entering the ejaculate (obstructive azoospermia) or those with significantly low sperm production.
Understanding PESA (Percutaneous Epididymal Sperm Aspiration)
PESA is often the first-choice method for obstructive azoospermia. It is a minimally invasive technique where an embryologist or urologist inserts a fine needle through the scrotal skin into the epididymis—the small tube where sperm is stored. Because it requires no surgical incision, the recovery is exceptionally fast. The aspirated fluid is immediately examined in our lab to identify healthy sperm for use in ICSI treatment.
Understanding TESA (Testicular Sperm Aspiration)
In cases where sperm cannot be found in the epididymis, or for non-obstructive azoospermia, TESA is performed. During a TESA procedure, a fine needle is inserted directly into the testis. Using negative pressure, the specialist extracts small amounts of testicular tissue and fluid. This tissue is then meticulously processed by our embryologists to harvest the sperm cells needed for fertilization.
TESA vs. PESA: Which Procedure is Right for You?
At Myra IVF, we tailor the choice between PESA and TESA based on the underlying cause of infertility.
- PESA: Best for men with a prior vasectomy or congenital absence of the vas deferens.
- TESA: Ideal for men with sperm production issues where the epididymis may not contain viable cells.
What Happens After Sperm Aspiration?
Once the sperm is successfully retrieved, it is cleaned and prepared in our IVF laboratory. Often, sperm obtained via sperm aspiration for male infertility are immature or fewer in number, which is why they are paired with Intracytoplasmic Sperm Injection (ICSI). In this process, a single healthy sperm is injected directly into the female partner's egg. These procedures are carefully synchronized with the egg retrieval cycle to maximize the chances of successful conception.
