A procedure performed on an outpatient (usually under local anesthesia) basis where one or more hair-thin biopsy specimens are removed and delivered to the embryology laboratory for sperm to be removed for ICSI.
(TESE) Dissection into the testis itself, in men with azoospermia due to maturation arrest, to recover (by 'teasing out') immature sperm cells from the (often small) fraction of testicular tubules there which still contain such cells. The sperm cells are used for in vitro fertilisation using intracytoplasmic sperm insertion (ICSI).
Microsurgical technique used to retrieve sperm directly from the testes after testicular blopsy. Sperm retrieved from the recovered testicular tissue are used for further fertilization through intracytoplasmic sperm injection (ICSI). TESE is used in instances where no sperm are stored in the epididymis or when there is no epididymis (see also ICSI and MESA).
Used to obtain sperm from a testicle for ICSI in cases of azospermia.
Retrieving sperm directly from the testis.
A procedure for extracting sperm by removing a small sample of testicular tissue through an incision in the testes. In the laboratory, the tissue is processed to extract sperm for use with intracytoplasmic sperm injection and in vitro fertilization.
A sperm retireval technique using open extraction.
A sperm retrieval technique using open extraction.
An open biopsy where a small piece of testicular tissue is removed through a skin incision. The tissue is placed in culture media and separated into tiny pieces. Sperm are released from within the seminiferous tubules where they are produced and are then extracted from the surrounding testicular tissue. This procedure can be done using local anesthetic of IV sedation. It is possible to get enough sperm to freeze for future use.
The method of retrieving sperm directly from the testes
Testicular Sperm Extraction (TESE) is the process of removing a small portion of tissue from the testicle under local anesthesia to extracting the few viable sperm cells present in that tissue for the purpose of Intracytoplasmic sperm injection (ICSI). The Testicular Sperm Extraction process is recommended to men who are unable to produce sperm by ejaculation as a result of primary testicular failure, congenital absence of the vas deferens or non-reconstructed vasectomy.
