A procedure in which a sample of sperm cells and tissue are removed from the testicle through a small needle attached to a syringe.
The sperm is separated from the tissue and looked at under a microscope in the laboratory.
It may then be used right away to fertilize eggs or frozen for future infertility treatment.
Testicular Sperm Extraction (TESE)
Testicular sperm extraction (TESE) is the surgical procedure of removing a small portion of tissue from the testicle and extracting any viable sperm cells from that issue for use in further procedures, most commonly intracytoplasmic sperm injection ( ICSI) as part of in vitro fertilisation (IVF).
TESE is often recommended to patients who cannot produce sperm by ejacalculation due to azoospermia.
