These procedures can be performed on an outpatient basis using sedation to eliminate any pain or discomfort. On withdrawing the needle, epididymal fluid continues to flow out of the punctured ductule and is aspirated from the epididymal surface. Since the tunica is not incised or sutured no blood vessel is damaged; hence, multiple biopsies can be taken without affecting the testis.
The amount of tissue recovered can be much less as compared to NAB. How many biopsies should be taken before accepting that no sperm can be found? High-resolution array-CGH analysis on 46,XX patients affected by early onset primary ovarian insufficiency discloses new genes involved in ovarian function. Initially, this can be achieved mechanically by mincing the tissue and submitting it to multiple passes through a fine needle that is attached to a syringe.

When one has to go into the testis itself to get the sperm, there are 2 ways of accomplishing this: 1) TESA (testicular sperm aspiration), which essentially is. If PESA fails then testicular sperm are obtained by needle aspiration biopsy (NAB ). . If motile sperm are not seen the procedure is repeated at a slightly different.

Once enough sperm are recovered the ductule is closed with microsutures. Since no microsurgical dissection or suturing is involved, the procedure is very quick, does not need special equipment or training, and can be performed under local anesthesia in the operation theatre of the IVF unit. Cutting needle biopsy Technique A testicular biopsy can also be obtained using a tissue-cutting biopsy needle[ 29 ] e.
Ultrasound-guided testicular sperm extraction Recently, it has been suggested that the use of ultrasound to identify and biopsy areas having greater perfusion may yield better sperm. Egg fertilization rates similar to that found with ejaculated sperm can be expected with vasal sperm. Using cryopreserved epididymal spermatozoa, the pregnancy rate of Since no microsurgical dissection or suturing is involved, the procedure is very quick, does not need special equipment or training, and can be performed under local anesthesia in the operation theatre of the IVF unit. This site complies with the HONcode standard for trustworthy health information: If no motile spermatozoa were found, another tubule was opened 0. Intracytoplasmic sperm injection with testicular spermatozoa is less successful in men with nonobstructive azoospermia than in men with obstructive azoospermia.
Men with azoospermia can father a child through intra-cytoplasmic sperm injection if sperm can be retrieved from their epididymis or testis. Several percutaneous and open surgical procedures have been described to retrieve sperm. The various techniques and their merits are discussed in this review. In men with obstructive azoospermia, epididymal sperm can usually be retrieved by percutaneous epididymal sperm aspiration PESA. In men with non-obstructive azoospermia, there will Motility of aspirated sperm no sperm in the epididymis and testicular sperm retrieval is required. Percutaneous retrieval by NAB can be tried first.
