Medical reasons that could result in an inability to produce sperm though ejaculation could consist of azoospermia ( No sperms ), low sperm count(Oligospermia), low sperm motility(asthenospermia).

Some procedures to recover sperms through the minor medical surgical process are as follow:

PESA (Percutaneous Epididymal Sperm Aspiration)

It is a surgical procedure which involves the use of needle and syringe technique as for a needle biopsy,  but the needle is directly placed into the epididymis. This often gives good results if there is a blockage in the vas deferens but the testis is producing sperms.


  • TESA: Testicular sperm aspiration. This procedure is similar to a needle biopsy but involves placing a needle attached to a syringe through the skin of the scrotum, and simply sucking out the fluid from  the testicle
  • TESE: Testicular sperm extraction. This is the procedure of extracting a large amount of the testicular tissue from the testicle by giving local anesthesia. Sperm is then retrieved using a microscope to identify individual sperm. This is done under anesthesia
  • MESA: Microsurgical epididymal sperm aspiration. This procedure is used in the conditions like contrary azoospermia; in this process, a working microscope uses to find the tubules of the epididymis so that the higher amount of sperms can be retrieved.

Some small studies have been done to compare success rates after the different types of surgical sperm retrieval. These concluded that MESA gives the highest number of sperm, with a hundred times more sperm being recovered compared to TESA and percutaneous biopsy. MESA also produced sperm that was better swimmers and therefore more useful for infertility treatments, including IVF and ICSI.

The advanced methods of retrieving the sperm from the testicles let male patients to utilize their own sperm in the ICSI  and the IVF treatment. These alternative procedures are not costly and offer joyful opportunity and save the cost of the sperm donor. At  Delhi IVF, We are focused to provide the most cost-effective treatment programs. In some cases, men do not produce any amount of sperm or very low that too of poor quality. Many of these men opt to directly retrieve their sperms from the testicles (TESA) or the epididymis, in which the sperms are stored before the ejaculation.

The retrieved sperm is then used during IVF (in-vitro fertilization), gestational surrogacy or egg donation treatments with Intracytoplasmic Sperm Injection (ICSI).


Even after all these exploratory procedures to retrieve sperms from epididymis or testis, there is still a chance that there are no sperms. The only avenue left is Sperm donation.
