Testicular Sperm Extraction
Testicular Sperm Extraction or TESE is a surgical sperm retrieval procedure used in fertility treatment for men who have no sperm in their ejaculate. TESE is used for men with both obstructive and non-obstructive azoospermia. These men have no sperm in their ejaculate either because of a blockage in the route between the site of sperm production (the testes) and ejaculation or there is a partial or complete failure in sperm production in the testes.
ESE is a minor theatre procedure carried out on an outpatient basis under local anesthesia by consultant urologist.
Sperm are retrieved from the testes and can be used to achieve fertilization of eggs in the laboratory. However, as the numbers of sperm that retrieved is often very low, it is necessary to combine TESE with ICSI.
