Invasive procedure to obtain sperm


Advantages Since only selective tubules are biopsied, less tissue needs to be removed resulting in less testicular damage. Therefore, assisted reproduction is needed for these sperm to result in a pregnancy. Heavy activities such as jogging and weight lifting can be resumed in 1 week. Similar to TESA, TESE is performed with a local anesthetic in most circumstances, but requires a small incision to expose the testicular tissue. When obstruction is the problem, which can occasionally be caused by conditions such as testicular cancer, TESA, PESA, Perc Biopsy or MESA are suitable. Sperm cryopreservation is an additional cost for both initial preservation and maintenance of the specimen.

Surgical sperm retrieval: Techniques and their indications

When the needle is placed against the testis and released, it enters the stroma, cuts a sliver of tissue and withdraws it into a sheath. A decade of experience emphasizes that testing for Y microdeletions is essential in American men with azoospermia and severe oligozoospermia. Obstructive azoospermia — when reconstruction has failed, or is not possible e. Since sperm will be found in only some men with testicular failure it would be ideal to first do a trial TESE and confirm the presence of sperm before subjecting the partner to the extensive hormonal stimulation required for IVF. Failure to ejaculate during an ICSI procedure if vibrator stimulation fails and electro-ejaculation is not available. We would recommend Dr. Samuel Thompson, urologist and male infertility specialist, of Urology of Indiana.

Sperm Retrieval, Preparation, Cryopreservation

Once the needle enters the tunica, suction is applied using a ml syringe. However, this implies that it would be possible to cryopreserve the scanty sperm obtained in these men and retrieve them in adequate numbers after thawing, with no reduction in the fertilization and pregnancy rate as compared to fresh sperm. Intracytoplasmic sperm injection with testicular spermatozoa is less successful in men with nonobstructive azoospermia than in men with obstructive azoospermia. If no sperm are found another ductule is dissected. This is slowly replacing TESE as a more optimal form of retrieval for men with no sperm in their semen.

Sperm Retrieval and Preparation

Invasive procedure to obtain sperm



Description: Abstract Men with azoospermia can father a child through intra-cytoplasmic sperm injection if sperm can be retrieved from their epididymis or testis. However, in men with testicular failure, in whom multiple biopsies have to be done, microsurgical biopsy techniques - which minimize testicular damage while allowing extensive sampling - are preferred to the conventional open testicular biopsy. These dedicated biopsy needles are spring-activated. A biopsy is taken from the testicular tissue and it usually retrieves a larger number of sperm. Many factors contribute to male infertility, including age, nerve damage, and physical obstructions of the reproductive tract.
