Testicular sperm extraction
Testicular Sperm Extraction (TESE)
Testicular Sperm Extraction (TESE), pronounced as /tɛstɪkjʊlər spɜːrm ɪkˈstrækʃən/, is a surgical biopsy procedure performed to extract sperm directly from the testes of men who are unable to produce sperm in their semen due to certain medical conditions.
Etymology
The term Testicular Sperm Extraction is derived from the words 'testicular' (pertaining to the testes), 'sperm' (the male reproductive cell), and 'extraction' (the process of obtaining something from a mixture or compound by chemical or physical or mechanical means).
Procedure
The TESE procedure involves making a small incision in the scrotum and extracting a small amount of tissue from the testes. This tissue is then examined in a laboratory to retrieve viable sperm for use in In Vitro Fertilization (IVF) or Intracytoplasmic Sperm Injection (ICSI) procedures.
Related Terms
- Microdissection TESE: A more precise form of TESE where a microscope is used to identify areas of the testes where sperm is likely to be found.
- Percutaneous Epididymal Sperm Aspiration (PESA): A procedure similar to TESE, but the sperm is extracted from the epididymis instead of the testes.
- In Vitro Fertilization (IVF): A process of fertilization where an egg is combined with sperm outside the body, in vitro ("in glass").
- Intracytoplasmic Sperm Injection (ICSI): An in vitro fertilization procedure in which a single sperm cell is injected directly into the cytoplasm of an egg.
