Percutaneous Epididymal Sperm Aspiration (PESA)

What is TESA/PESA?

PESA (percutaneous epidydimal sperm aspiration) and TESA (testicular sperm aspiration) are procedures that are performed to obtain sperm in certain cases of male infertility. PESA or TESA can be performed on men that have zero sperm counts due to either a sperm production problem or a blockage in their reproductive tract, such as the result of a vasectomy, congenital absence of vas deferens, or infection.

Once a diagnosis of azoospermia (zero sperm count) has been made, we work closely with a urologist with specialized training in male infertility who will retrieve the sperm. The urologist will first perform an exam and further testing which may involve blood work and/or a testicular biopsy. The result of these studies determine which procedure is more appropriate and more likely to yield sperm.

While PESA is usually performed in our Center the morning of the egg retrieval, TESA may be done the day prior to the egg retrieval to allow in vitro maturation of immature sperm. With PESA, a small needle is placed into the epidydimis, which is a reservoir of sperm that sits atop each testicle, using local anesthesia. During TESA, sperm is obtained by means of a biopsy of the testicle. The sperm obtained from these procedures is then injected directly into the eggs (ICSI).

The Fertility and IVF Center of Miami is proud to have announced on August 12, 1997, the birth of the first baby in Florida conceived with the aid of PESA.

Intra-Cytoplasmic Sperm Injection (ICSI)

From the fertility booklet The A.R.T. of Fertility: A patient guide
by the Fertility & IVF Center of Miami

What is Assisted Fertilization?
In some cases of male infertility, the usual mixing of egg and sperm may not result in a fertilized egg. A technique termed ICSI (intracytoplasmic sperm injection) in which a single sperm is injected directly inside the egg with a microscopic needle, may offer a solution to those with severe male infertility. This technique is performed in the laboratory the day of the retrieval using mature eggs.

Prognosis for Success - Explanation of Our IVF Statistics

Following is an explanation of our IVF statistics shown above:

  • Comparison of clinic success rates: The ASRM provides the following statement about comparing clinic success rates: "A comparison of clinic success rates may not be meaningful because patient medical characteristics and treatment approaches vary from clinic to clinic." October 1999.

  • Using pregnancy rates, rather than live birth rates: Understanding a success rate is paramount to gaining an appreciation for how likely it is to have a baby. SART (Society of Assisted Reproductive Technology) published success rates are expressed as live births per cycle of treatment initiated subdivided by age. Unfortunately this methodology means that data is about two years old when it reaches the patient. We strongly believe that the most relevant data to evaluate a program is from the previous calendar year. Since live birth rate data is not yet available, pregnancy rates are expressed as ongoing but not delivered.

  • Per embryo transfer: The table above expresses our pregnancy rates for the year 2008, per embryo transfer procedure.

  • Definitions of items used in the above table:

    • Patient's age: By tradition we have broken down results by the patient's age. Egg recipient cycles are grouped together as all egg donors are under age 35.

    • ultrasound confirmed: An ultrasound confirmed pregnancy is one at six to eight weeks with a gestational sac and heartbeat seen on ultrasound imaging.

    • ongoing pregnancy: Ongoing pregnancy means that the pregnancy has progressed to at least 20 weeks (5 months) gestation.

  • Age is not the only factor influencing IVF success: It is important to remember that age alone is not the only factor influencing IVF success. Factors including ovarian reserve, baseline FSH level, prior ovarian surgery, endometriosis, multiple unsuccessful previous cycles, uterine abnormalities (such as congenital abnormalities or myomas), tubal factors (such as hydrosalpinx), and genetic factors all will influence how successful a procedure may be.


We encourage all patients to specifically address the question of their "prognosis for success" with one of our physicians. In this way, all contributory factors pertinent to the individual couple may be considered and an appropriate individual prognosis can then be defined.


* Most-recent SART-published statistics.  Clinical pregnancy rate per cycle of embryo transfer.  Note that a comparison of clinic success rates may not be meaningful because patient medical characteristics and treatment approaches may vary from clinic to clinic.
