TESA or TESE: Which Is Better for Sperm Extraction?

Nowadays, people are aware of the main reasons for female infertility. However, few know what can cause male infertility and where to find a solution to this problem. Modern technologies and medical breakthroughs provided us with several ways of sperm extraction, which then should be used for examinations and tests, or even for in vitro fertilization. Which method is the best one is the matter of ongoing disputes between doctors. Therefore, it is necessary to look at all of them in more detail.

TESA or TESE Procedure

TASA and TESA IVF procedures are considered the most popular in the whole world. They have the same purpose – sperm extraction. However, the methods of achievement, results and success rates are rather different. Both of them can be carried out at andrology or urology departments of IVF clinics, for example, the International IVF group in Ukraine. IVF with TESE, as well as with TESA, is conducted under anesthesia and lasts for 15-20 minutes.

TESA IVF Treatment

TESA IVF is short for testicular sperm aspiration. A doctor takes a sperm sample directly from the testicles using a needle and light suction. It means that no sign of this procedure will be observed in the future. However, this method produces only a small amount of sperm. It can be examined under the microscope to identify the sperm cells’ condition. If there are no problems, sperm can be taken one more time for the in vitro fertilization process. In other cases, special treatment for a man can be prescribed, or a couple can be advised to use a donor material.

In Vitro Fertilization


TESE procedure stands for testicular sperm extraction. This process is more complex and is commonly known as a surgical biopsy. IVF TESE procedure requires making a small incision and taking a sample of sperm from the testis. It produces a larger amount of sperm compared with the previous method. This sperm can be used for in vitro fertilization or frozen to complete this process later. Taking into account the complexity of this procedure, IVF with TESE requires suturing and leaves some small signs of the surgery.

What are the Success Rates for Both Methods? IVF with TESE success rates is usually estimated a little higher than TESA. The main advantage is the amount of sperm. However, there is no point in extracting a lot of sperm if you need it only for examination. It means that IVF with TESE success rates can be equal to TESA  fertilization, but the first one is more frequently used. The choice depends on the patient’s diagnosis and condition.
