What is TESA and how is it done?

TESA or Testicular Sperm Aspiration is one of the newest sperm retrieval techniques. This treatment is recommended to men with Azoospermia, a condition in which a lack of sperm is found in their ejaculate.In the past, the only options for treating azoospermia were reconstructive surgery (if there was obstruction) or donor insemination. Now, the advent of intra-cytoplasmic sperm injection (ICSI) has enabled many azoospermic men to become biological fathers using sperm obtained from their epididymis or testis
This surgical sperm retrieval procedure is used in men:
- If their testicles are not making enough sperm or Non-obstructive Azoospermia or
- If due to some blockage, the sperms get blocked from passing out to the semen or Obstructive Azoospermia
Extremely poor sperm production can be a hindrance to their fertility. In such cases, TESA has been a major breakthrough in extracting the sperm directly from a man’s testis. Men with azoospermia can father a child if sperm is retrieved from their testis or epididymis. This procedure is used in men with non-obstructive Azoospermia, wherein no sperms can be retrieved from the epididymis.
How is TESA Done?
Testicular sperm aspiration is performed by inserting a needle into the testis and aspirating fluid and tissue using negative pressure. The sample is then processed to extract the sperm cells in the embryology laboratory using the ICSI or Intracytoplasmic sperm injection.
The sperm cells need not have to be mature and pass through epididymis to fertilize an egg. Since the testicular sperm is immature, they need ICSI, a technique in which a single sperm is taken from the semen and injected directly into the egg.
TESA can give some discomfort for a few days as it’s a slightly complex procedure. It is done under local anesthesia or sedation as per the patient’s preference in day care no need of any hospital stay. If TESA doesn’t provide enough sperm, testicular biopsy is needed in such cases.
Much speculations and concerns have been raised about the use of genetic material from a developing sperm cell. Also, there can be a chance that the cause of infertility can be transmitted to the progeny.
