Testicular biopsy is a simple surgical procedure used to obtain testicular tissue in order to detect the presence of spermatozoa and use them to fertilise the oocytes obtained during an ovarian stimulation cycle.
There are several techniques for performing testicular biopsy, such as TESA (testicular semen aspiration) or PESA (epididymal sperm aspiration), which are among the most commonly used for being minimally invasive and comfortable for the patient.
Testicular Biopsy
Testicular biopsy is a simple surgical procedure used to obtain testicular tissue in order to detect the presence of spermatozoa and use them to fertilise the oocytes obtained during an ovarian stimulation cycle.
There are several techniques for performing testicular biopsy, such as TESA (testicular semen aspiration) or PESA (epididymal sperm aspiration), which are among the most commonly used for being minimally invasive and comfortable for the patient.
Who is it for?
Testicular biopsy is indicated when it is not possible to obtain spermatozoa in the ejaculate. This may be due to different reasons:
- Absence of sperm in the ejaculate (azoospermia).
- Absence of live sperm in the ejaculate (necrospermia).
- Previous vasectomy or obstruction of the ejaculatory duct.
- Severe alterations in sperm quality.
- Low fertilisation rate in previous treatments.
After assessing your case, Vida Fertility team will design the most appropriate strategy for your treatment.
How is the Testicular Biopsy process?
Testicular biopsy is performed by aspiration of small testicular fragments. It is performed under local anesthesia and does not require hospitalisation. Thanks to this very minimally invasive procedure, it is possible to aspirate seminal tubes of spermatozoa for subsequent observation in the laboratory. If live sperm are recovered, the ICSI technique will be used for its fertilisation with the oocytes of the patient or a donor.
If you have azoospermia, poor sperm quality or a lack of sperm, a testicular biopsy may be the solution for you.
This procedure allows us to identify and extract sperm directly from the testicles, increasing your chances of fatherhood through assisted reproduction techniques.
