Surgical Sperm Retrieval -Closer Towards Fatherhood

Posted On 13-1-2018

Surgical sperm retrieval is a technique that aid couples who suffer infertility due to a lack of sperm in the ejaculate. The procedure is usually conducted in conjunction with ART (Assisted Reproduction Techniques) and includes the extraction of sperm directly from the testicles or epididymis through a mild surgical procedure.

Low sperm count in ejaculate in the male partner can occur due to various reasons. They can range from a blockage in the path of sperm delivery to hormonal imbalances or injuries hampering the production of sperm. Surgical sperm retrieval techniques help in achieving successful pregnancy by overcoming these deficiencies to some extent. 

Scope of surgical sperm retrieval

The procedure is usually helpful in the following cases: -
If there is an obstruction in the path of sperm delivery, reducing its count in the ejaculate
Some sort of congenital abnormalities in the vas deferens, which is the tube carries sperm from the testes.
For men who have undergone vasectomy previously
For those suffering from non-obstructive azoospermia where the sperm production is too low to reach the vas deferens.

Surgical sperm retrieval techniques

Surgical sperm retrieval techniques are conducted under mild general or local anesthesia. The procedure does not warrant an overnight stay. The different types of surgical sperm retrieval techniques as follows:

  • PESA (Percutaneous Epididymal Sperm Aspiration)
  • TESA (Testicular Sperm Aspiration)
  • MESA (Microsurgical Epididymal Sperm Aspiration)
  • TESE (Testicular Sperm Extraction)
  • Micro-dissection TESE

Surgical sperm retrieval is often effective in cases of sperm deficiency due to obstructions or obstructive azoospermia. Sperm is directly aspirated from the epididymis with the help of various sperm retrieval techniques such as PESA or TESA.


The technique can help in cases of non-obstructive azoospermia to some extent as well. Here as the production of sperm is very low or negligible, a low concentration of sperm can be obtained with the help of random biopsies conducted on the cell tissues. Surgical sperm retrieval techniques such as TESE are used in these cases.
