They will need to undergo a second surgical procedure on their testicles in order to actually put any of that sperm to use in an IVF cycle. Surgical Techniques for Non-Obstructive Azoospermia Sperm are rarely present in the epididymal tissue of patients who have non-obstructive azoospermia. Epididymal aspiration is more likely to produce motile sperm than testicular sperm retrieval. This means that once sperm are located and the map is created, another microsurgical procedure microTESE needs to be performed to find those tubules that have sperm and remove them to have enough sperm to use for IVF or to freeze. The potential for complications is higher with a TESA for two important reasons. Werthman will need to have a thorough knowledge and understanding of the cause of your infertility prior to recommending and performing any particular procedure.

Microsurgical Epididymal Sperm Aspiration And

The impact of sperm motility on fertilization and clinical pregnancy rates was determined. They will need to undergo a second surgical procedure on their testicles in order to actually put any of that sperm to use in an IVF cycle. A frequently asked question is can the sperm harvested by these techniques be used for insemination. Micro-TESE is more effective and potentially safer than needle biopsy TESA and is our technique of choice for obtaining testicular sperm for men with non-obstructive azoospermia. Werthman can observe the interior of the testicle and select the best candidate areas to examine for sperm production.

Werthman will need to have a thorough knowledge and understanding of the cause of your infertility prior to recommending and performing any particular procedure. Sperm Aspiration is very successful when the proper technique is used Sperm aspiration when performed using the appropriate technique is usually a very successful, minimally invasive procedure that allows even men who make very few sperm to conceive a child of their own. Werthman can observe the interior of the testicle and select the best candidate areas to examine for sperm production. With this micro-surgical procedure, Dr. Werthman may recommend harvesting sperm directly from the testicles in an effort to find viable sperm. This is a relatively painless and minimally invasive procedure performed in our office under local anesthesia.

Description: Obstructive azoospermia is the result of a blockage in the male reproductive tract. A grid with sections is drawn over the testicle and a needle is blindly inserted into each area to remove aspirate a small section of the tubules and sample them for sperm. There are two main reasons why sperm may be absent from the semen necessitating sperm aspiration. Many embryologists find this small amount of tissue difficult to work with and do not get enough sperm to freeze for future use. Schedule a private consultation with male fertility doctor Dr. It is precisely these situations that require advanced reproduction technologies such as ICSI to establish a pregnancy.
