Surgical Sperm Retrieval (TESA, TESE, MESA, PESA)

In assisted reproductive technology, semen samples are typically obtained via standard collection methods. However, in clinical cases involving azoospermia, severe oligospermia, or obstructive conditions where spermatozoa are absent in the ejaculate, specialized surgical sperm retrieval procedures are indicated. These techniques allow for the recovery of spermatozoa for utilization in assisted reproductive procedures such as Intracytoplasmic Sperm Injection (ICSI).

PESA (Percutaneous Epididymal Sperm Aspiration)

PESA is a minimally invasive outpatient procedure performed under local anesthesia. A fine needle is introduced into the epididymis to aspirate fluid containing spermatozoa, which are subsequently prepared for use in ICSI.

TESA (Testicular Sperm Aspiration) & TESE (Testicular Sperm Extraction)

When epididymal sperm retrieval is not feasible or in cases of non-obstructive azoospermia, testicular sperm retrieval methods are utilized. TESA involves aspirating testicular tissue via needle aspiration under local anesthesia, whereas TESE involves a minor surgical testicular biopsy to retrieve seminiferous tubule tissue for spermatozoon extraction.

MESA (Micro-Epididymal Sperm Aspiration)

MESA is a microsurgical procedure performed under anesthesia where the epididymis is accessed to retrieve spermatozoa directly. Post-procedure care includes standard wound management and prescribed analgesia to manage temporary postoperative discomfort.

Surgical sperm retrieval techniques enable patients with severe male factor conditions to utilize their own gametes in assisted reproductive treatments such as IVF combined with ICSI.
