PESA/TESA-boon for male infertility

In case of male factor infertility, some men will not have enough sperm in their ejaculation to succeed with IVF. Due to the advancements in infertility treatments, these men will have opportunity to proceed with IVF. The sperm which is residing in the testicles can be obtained with the advanced treatments like TESA and PESA. These techniques are highly helpful for the partners with male factor infertility. If the male partner is not able to ejaculate sperm, small amount of sperm can be obtained directly from the epididymis or testicles that are sufficient for IVF treatment.

Benefits from surgical sperm retrieval

Testes are the place for the formation of sperm and it is stored in the epididymis when mature. For the men who are facing ejaculation problems, they cannot able to reach ejaculation with the produced sperm. This problem is mainly due to:

  • Blockage/absence of vasa deferens
  •  Due to testicular disorders.

TESA/ PESA/ Testicular Biopsy

PESA (Percutaneous Epididymal Sperm Aspiration)

  • This procedure is mainly performed under sedation stage by giving pain relief and general Anesthesia.
  • In some cases, directly from epididymis, sperm can be extracted.
  • Through the scrotum skin, a fine needle is inserted and passed it to the epididymis.
  • Small amount of sperm and transferred to examination.

TESA (Testicular Sperm Aspiration)

  • By passing a needle directly into the testicles, sperm is extracted
  • Along with the sperm, a small amount of tissue is collected examined in the laboratory.
  • Before performing these tests, investigations are required to envisage whether sperm is present or it can be obtained at the biopsy and also some tests to check the conditions that could cause problems to the children born from the procedure.

Testicular Biopsy

This method can be used to:

  •     diagnose the location and condition of a lump in the testes
  •     diagnose causes of male infertility
  •     obtain sperm for in vitro fertilization (IVF)

In this process, the semen of the men obtained from both the testicles is diagnosed under the microscope in order to evaluate the ability of men to become a father to a child. This test determines the causes of infertility in men.
