However, testicular sperm does not respond to cryopreservation as well as normally ejaculated or epididymal sperm. Sperm are rarely present in the epididymal tissue of patients who have non-obstructive azoospermia. Non-obstructive azoospermia is the result of severely impaired or non-existent sperm production. What is surgical sperm extraction? You will receive antibiotics to prevent infection, and pain medications to help manage any soreness of the treatment area. MicroTESE is carefully coordinated with the reproductive endocrinologist and is performed at designated times on a quarterly basis. You may feel slight discomfort and tenderness on the scrotum for the first 24 to 48 hours.
Therefore, in these cases, it must be realized that the condition which may have caused the infertility, may be transmitted to the progeny. Werthman will extract sperm from their storage site in the epididymis with the aid of a surgical microscope. The testicular tubules and fluid are placed into a small amount of culture media and the specimen is delivered to the embryology team. The process does not require hospitalization, is painless when done under sedation, and recovery is virtually immediate. Men who can ejaculate, but lack sperm in their ejaculate frequently have at least some sperm in their testicles.
Sperm aspiration is an alternative to vasectomy reversal not only is it cheaper, but it is far less painful. When the biological clock is ticking. It is precisely these situations that require advanced reproduction technologies such as ICSI to establish a pregnancy. Testicular sperm extraction is indicated for patients in whom there is a blockage in the epididymis very near the testis either from prior surgery, infection or from birth , or a blockage within the ducts of the testes efferent ductules. Men born with an absent vas deferens Men with irreversible obstructions of the genital tract Men facing testicular problems with deficiency of spermatogenesis Men with failed vasectomy reversal.
MicroTESE has significantly improved sperm retrieval rates in azoospermic men, and is a safer procedure since less testicular tissue is removed. Only men with no sperm in their ejaculate azoospermia need to have sperm retrieved directly from the testis or epididymis. MicroTESE involves examining the testicle with an operating microscope to find areas tubules where sperm are being made. The collected sperm are intended specifically for use with intracytoplasmic sperm injection ICSI. Side effects tend to be rare but bleeding and infection can occur. IVF laboratories frequently prefer to work with fresh rather than frozen sperm and thus their desire to have fresh sperm trumps any other consideration. Journal List Rev Urol v.
