TESE / PESA Sperm Retrieval

TESE and PESA are sperm retrieval techniques used for selected men with azoospermia or severe male factor infertility. Retrieved sperm may be used with IVF and ICSI.

PESA retrieves sperm from the epididymis using a fine needle. TESE retrieves sperm from testicular tissue. The choice depends on the suspected cause of azoospermia, clinical examination, hormone results and specialist advice.

These procedures can help couples proceed with treatment even when sperm is not present in the ejaculated sample. In some cases, sperm may also be frozen for future use.

A full male fertility evaluation is important before planning TESE or PESA, including semen analysis, hormonal testing and counselling about likely outcomes.
