Surgical Sperm Retrieval


What is Surgical Sperm Retrieval?


Surgical sperm retrieval is performed when no sperm can be found in the ejaculate (azoospermia). This can occur when: 1.  sperm are produced in testicle but are blocked from being transported into the ejaculate, or 2. sperm production in the testicle is severely impaired.

In either situation, surgical sperm retrieval may be successful by performing extraction of spermatozoa from the testicle or epididymis through microsurgery.

Surgical Sperm Retrieval is prescribed to:

  • Males with azoospermia (when the ejaculate does not contain spermatozoa);
  • Males with ejaculation problems;
  • Males with total asthenozoospermia/necrozoospermia (when all spermatozoa in the ejaculate are immotile);
  • Males with vasectomy in the past (male sterilization).

Spermatozoa extracted through sperm aspiration are used for In-Vitro Fertilization with intracytoplasmic sperm injection (ICSI) to enable the couple to have a biological child.

The male infertility specialist decides whether surgical sperm retrieval should be performed based on the following tests: semen analysis (spermogram), hormonal analyses, physical examination and reproductive gland ultrasound. Microsurgery is a brief procedure with intravenous anesthesia.

Sperm aspiration uses different microsurgery methods:

  • PESA: Percutaneous epididymal sperm aspiration
  • TESA: Testicular sperm aspiration
  • TESE: Testicular sperm extraction
  • MESE: Microsurgical testicular sperm extraction.

ReproART Clinic’s Approach


The Georgian-American Clinic ReproART and its highly qualified personnel conduct successful surgeries on the testicle and its epididymis.

65% of the sperm aspirations at ReproART result in motile spermatozoa. However ICSI is always performed with sperm obtained using surgical sperm retrieval. Of course, if no sperm are found the couple may need to use sperm from a donor.


To plan consultations with the ReproART Clinic’s andrologist or urologist, please set an appointment in advance.
