MESA/TESE

 MESA/TESE

In some cases, a male's fertility disorder is caused by changes in chromozomes.Therefore a genetic examination prior to  further treatment is warranted.

In cases of a repeat confirmed azoospermia (no living spermatozoa in ejaculate),it is sometimes possible to gain sperm cells by surgical means of MESA or possibly TESE.


MESA (Micro Epididymal Sperm Aspiration)

Mesa is a process by which spermatozoa are microsurgically aspirated from the epididymis - this procedure is performed in case of sperm transport failure between epididymis and uretra. This intervention is performed under general anaesthetic.A 3cm incision is made on the scrotum thus providing access to epididymis.A pipette is used to aspirate fluid from the ducts. During surgery, the fluid is elaborately analyzed in a microsurgical laboratory. In the event that live spermatozoa are found, they are used for ova fertilization through the ICSI method.


TESE (Testicular Sperm Extraction)

In the event that no sperm cells were obtained through MESA, we use the technique TESE. In this way it is possible, as far as they exist, to gain sperm cells from the ducts of germinal epithelium which are not capable of release or transport from a testicle to epididymis.

This procedure is a follow-up to the previous procedure MESA. From a small incision in the testicle cover a small amount of testicle tissue is obtained. This tissue is further treated in the laboratory. In the event that live spermatozoa are found during this procedure,they are used for ova fertilization through the method ICSI.
