He is described by his patients as being personable, kind, and encouraging. In the most severe forms of male factor infertility, the male partner is completely azoospermic, defined as no sperm is found on semen analysis even after centrifugation on two completely collected specimens separated by at least one month. Clearly, one of the biggest gaps in our knowledge of non-obstructive azoospermia is finding predictors of spermatogenesis that can be used to guide patients regarding the decision to proceed with sperm retrieval. Fine needle aspiration TFNA is the same procedure as performed for obstructive azoospermia see earlier in review. MESA is more cost effective than other techniques because it is usually a one-time expense whereas the other sperm retrieval techniques may need to be repeated multiple times. For this reason, it is vitally important to perform a testicular biopsy in this scenario in a center with the ability to quantify and cryopreserve the tissue and sperm.
Microsurgical Sperm Retrieval
Well repeat this procedure on the opposite side. Clinical expertise, compassionate care. In addition, the lack of specialized equipment required, such as an operative microscope or microsurgical instrumentation, and the ability to perform the procedure with minimal training, make percutaneous approaches more available, particularly at short notice. The procedures have clear-cut advantages and drawbacks, and not all are applicable to every situation. Testicular and epididymal percutaneous sperm aspiration in men with either obstructive or nonobstructive azoospermia.
Non-Obstructive Azoospermia and the Impact of MicroTESE – Irish Medical Journal
Percutaneous vasal sperm aspiration PVSA PVSA was initially described in in six patients with OA secondary to abdominal vasal obstruction or ejaculatory duct obstruction, of which four patients had successful retrieval of motile sperm. Sperm are formed in the testes and stored in the epididymis when mature. Unfortunately it is not always possible to retrieve sperm. Percutaneous vasal sperm aspiration and intrauterine insemination for infertile males with anejaculation. Clinically significant complications after sperm retrieval are rare; however, in the available literature on sperm retrieval techniques, complications are infrequently reported. Sperm Harvesting for In Vitro Fertilization Sperm aspiration refers to the group of surgical procedures that are used to obtain viable sperm from the male reproductive tract.

Uncover an easier path to parenthood. Diagnostic findings from testis fine needle aspiration mapping in obstructed and nonobstructed azoospermic men. The biopsy procedure carries a small risk of bruising and infection to the biopsy site. This is a percutaneous approach and is less invasive than TESE. Occasionally, the physician will need to make a small surgical incision into the testicle TESE to get sperm if no sperm are found at the time of PESA or if sperm quality is poor.
