Cutting-Edge Sperm Extraction Methods: A Closer Look at TESE and MESA


Sophisticated sperm retrieval methods like Testicular Sperm Extraction (TESE) and Microsurgical Epididymal Sperm Aspiration (MESA) offer hope for a lot of infertile men. At SCI IVF Hospital, the leading male infertility treatment center in Delhi NCR, we are experts in these innovative procedures that provide answers to severe male infertility.

Testicular Sperm Extraction (TESE)

It is a surgical procedure designed to recover sperm from the testicle itself. It works best when sperm production is very low or nil due to testicular dysfunction i.e., non-obstructive azoospermia. Here’s how it works:

  • Procedure: An incision is made in the testicle under local or general anesthesia, and some testicular tissue is extracted for analysis of sperm’s presence.
  • Sperm Retrieval: In the laboratory, viable sperms are isolated from processed tissue, which can be used for Intracytoplasmic Sperm Injection (ICSI), a specialized form of In Vitro Fertilization (IVF).
  • Recovery: The procedure is minimally invasive with quick healing time and little discomfort experienced by most patients.

It allows men who cannot produce sperm naturally or have genetic conditions affecting its production to become fathers. Many couples have been able to achieve parenthood through the success rates recorded by TESE combined with ICSI.

Microsurgical Epididymal Sperm Aspiration (MESA)

This technique targets obstructive azoospermia where there are no sperms present in ejaculate because they get blocked on their way out, but production remains normal within them. Congenital problems, infections, or past surgeries such as vasectomy may cause this blockage, MESA solves it like so:

  • Procedure: Under general anesthesia, a small cut is made in the scrotum, and with the aid of a microscope sperm cells are located from the epididymis, which serves as their maturation and storage area.
  • Sperm Retrieval: The fluid that has been aspirated is checked for retrieval of best-quality sperms that can be used immediately or frozen for future use during ICSI.
  • Precision: The procedure employs microscopes, so it is very accurate and reduces harm caused to fragile parts of the reproductive system during the intervention.

When and Why These Techniques Are Used

TESE and MESA are employed at our top male fertility treatment centre in Delhi, when conventional methods of sperm retrieval, such as ejaculation or less invasive aspirations, are not viable. These techniques are necessary for:

  • Men with azoospermia (obstructive/non-obstructive)
  • Patients whose other fertility treatments have failed
  • Couples who want to increase their chances of success with IVF/ICSI.
