a test in which a small sample of tissue is taken from one or both testicles and examined under a microscope to evaluate a man's ability to father a child
a test to remove a small sample of tissue from one or both - testicles - and examined
A procedure that allows for microscopic examination of a tissue sample that is removed through a small incision in the scrotum and contains the semniferous tubules that produce sperm. The results can help determine causes of infertility and suggest a course of treatment.
With some cases of severe male factor infertility it is not possible to retrieve sperm from the epididymis with MESA. In those cases, a surgeon can remove a small piece of the testicle and the embryologists in the IVF laboratory can extract sperm from that piece of testicle. ICSI is also required with sperm from testicular biopsy in order to fertilize the eggs.
Open - the removal of testicular tissue (0.5ml) from men with very poor sperm production and the isolation of sperm for ICSI. This procedure is performed under a general anaesthetic. Fine needle - this is performed under a local anaesthetic and involves the insertion of a needle into the testis to remove a small fragment of sperm tubule in cases of obstruction. In this setting an adequate number of sperm can be obtained for use in ICSI.
The removal of microscopic bits of the testicular tissue from men with very poor sperm production. Immature sperm are recovered from the tissue and injected into the egg using ICSI.
Taking a small piece of flesh or 'tissue' from the testis and examined under a microscope
The surgical removal of testicular tissue to determine if the cells have the ability to produce normal sperm, or to diagnose possible neoplasms. close window
A minor surgical procedure used to take a small sampleof testicular tissue for microscopic examination. Sperm may be retrieved usinga testicular biopsy when there is a tubal blockage which is preventing spermfrom being ejaculated.
Surgical excision of testicular tissue to determine the ability of the testes to produce normal sperm
A procedure that allows for microscopic examination of a tissue sample containing the semniferous tubules that contain sperm. The sample, removed through a small incision in the scrotum, can help determine the causes of infertility and suggest a course of treatment.
A small excision of testicular tissue to determine the ability of the cells to produce normal sperm.
Removal of a sample of testicle tissue for laboratory examination.
A minor surgical procedure used to take a small sample of testicular tissue for microscopic examination; a test used to diagnose male fertility problems when no other means is available (this is because the biopsy procedure itself may cause testicular damage).
