Sperm Extraction (TESA, TESE, PESA, MESA) to Treat Male Infertility
Regain fertility with testicular sperm extraction (TESE, PESA, MESA) at Reproductive Fertility Center
Infertility can occur in men for various reasons. Little to no motile sperm may be present in their ejaculate, blockages may prevent the delivery of sperm, or ejaculation may not be possible. Potential reasons for these issues include a previous vasectomy, being born without a vas deferens, and having a low sperm count due to lifestyle factors or genetics.
Sperm extraction procedures can help men suffering from these conditions improve their fertility despite these causes. The sperm (spermatozoa) can be harvested directly from in or near the testes, and the healthiest, most viable sperm can be isolated. The sperm can then be used with other fertility treatments to achieve fertilization.
What are TESA, TESE, PESA, and MESA?
TESA: Testicular Sperm Aspiration
Testicular sperm aspiration involves using a small needle to extract sperm directly from the testis (testicle).
While this is generally done under local anesthesia, it can be done under general anesthesia if you are anxious or nervous and prefer to be asleep during the procedure.
TESE: Testicular Sperm Extraction
Testicular sperm extraction is a surgical procedure that uses a small incision in the testis (testicle). A small portion of testicular tissue that contains sperm is removed.
This procedure is performed with the patient under general anesthesia.
PESA: Percutaneous Epidydimal Sperm Aspiration
The epididymis is a tube behind the testis that joins the testicle to the vas deferens. PESA involves using a small needle to extract sperm from the epididymis.
This can be performed with the patient under local or general anesthesia based on their preference.
MESA: Microsurgical Epidydimal Sperm Aspiration
Microsurgical epidydimal sperm aspiration uses a small incision in the testicle to access the epididymis (the tube behind the testicle). A small needle is then used to aspirate sperm from the epididymal tubule.
MESA is performed with the patient under general anesthesia.

“Eternally Grateful”
It is amazing what a difference a year can make. Last year we were feeling depressed and anxious and unsure about whether or not this would happen for us. This year we are expecting the birth of our first child. Dr. Saadat is amazing. You will feel the difference right away between his office and any other office around. They must make it a rule there to only hire friendly, compassionate people because everyone there was so sweet – especially all the nurses. Thanks again for everything guys!
"Felt Welcome From the Start"
I wanted to say thank you to the entire staff for making us feel welcome to our first visit especially on a Saturday. We met with Dr. Sadaat and was very informative and took time with us with all of our questions. For the financial department, Melissa was very helpful with keeping in contact with us regarding any paperwork that we needed as well as with setting our appointment. We do look forward for treatment with Dr. Saadat.
"The Solution to Our Problems"
We just celebrated our son’s first birthday, and thought we should send out warm wishes to Dr. Saadat and his team as well. Without them this would not have been possible. We had “unexplained” infertility issues and the first clinic we went to was not very friendly and we felt like we were just another “cycle”. Dr. Saadat was always willing to answer questions and the nurses there were terrific. I felt like everyone in the office was on our side, and that makes a huge difference. So thank you to everyone from Anna, Michael and Alex.
"One Big Thank You"
Dr Saadat is very open and accommodating to my financial and medical concerns. He doesn’t force unnecessary tests like other places do. He’s a very nice and efficient reproductive endocrinologist.
"Helpful in Every Way"
We traveled across the world to be treated by Dr. Saadat. My wife was not able to have babies and we could not get an answer from Doctors in our country why. It is also important in our culture that our first baby be male. Dr. Saadat was able to help my wife get pregnant and make sure that we had a baby boy. They were helpful in every way and we felt comfortable even though we are not from the United States. Everyone was patient and understanding and respectful. We will be back in a few years to grow our family.
"It's Never Too Late!"
All I can say is do not give up hope! I was 43 when I got pregnant for the first time. I had honestly been trying for years. I now have 3 beautiful children, a 6 year old girl and 3 year old twins – a boy and a girl. I feel blessed every day. It can happen. Thank you Dr. Saadat.
"The Perfect Fit for the Job"
I came to Dr. Saadat’s office because I felt like the Doctor I was working with was not a good fit. It isn’t that they were doing anything wrong but I did not feel a connection. This is such a personal type of medical treatment, and I want the people helping me to make me feel cared for. Dr. Saadat’s approach is also a bit different – he does all the ultrasounds himself – which is very reassuring. His staff is great, and his bedside manner is comforting. I am thankful for everything they all did, and thankful everyday for my daughter!
