TESE and Micro-TESE: Advanced Solutions for Male Infertility

What Are TESE and Micro-TESE Procedures?

Male factor infertility accounts for approximately 40 to 50 percent of all infertility cases, and one of the most challenging conditions men face is azoospermia, the complete absence of sperm in the ejaculate. For men diagnosed with azoospermia, TESE (Testicular Sperm Extraction) and Micro-TESE (Microsurgical Testicular Sperm Extraction) offer advanced surgical solutions that can make biological fatherhood possible.

At GynoLife IVF Center in Cyprus, our urologists and reproductive specialists work together to provide these cutting-edge procedures, giving men with azoospermia the best possible chance of having genetically related children through IVF with ICSI.

Understanding Azoospermia

Before exploring TESE and Micro-TESE in detail, it is important to understand the condition these procedures address. Azoospermia is classified into two main types, and the type of azoospermia determines which surgical approach is most appropriate.

Obstructive Azoospermia (OA)

In obstructive azoospermia, the testes produce sperm normally, but a blockage in the reproductive tract prevents sperm from reaching the ejaculate. Common causes include previous vasectomy, congenital absence of the vas deferens (CAVD), prior infections, or surgical trauma. Men with OA typically have normal testicular size and normal hormone levels. Sperm retrieval success rates in OA cases are very high, often exceeding 95 percent.

Non-Obstructive Azoospermia (NOA)

Non-obstructive azoospermia occurs when the testes have impaired or absent sperm production. This is the more challenging form of azoospermia and can result from genetic conditions such as Klinefelter syndrome, Y-chromosome microdeletions, hormonal imbalances, testicular failure, or previous chemotherapy or radiation treatment. Micro-TESE was specifically developed to address NOA cases and has revolutionized treatment outcomes for these patients.

TESE: Testicular Sperm Extraction

Testicular Sperm Extraction (TESE) is a surgical procedure in which small samples of testicular tissue are removed and examined for the presence of sperm. This technique has been a cornerstone of male infertility treatment since its introduction in the 1990s.

How TESE Is Performed

The conventional TESE procedure is performed under local anesthesia with sedation or general anesthesia, depending on patient preference and clinical requirements. The surgeon makes a small incision in the scrotal skin, exposes the testis, and obtains multiple small biopsies of testicular tissue from different areas. These tissue samples are immediately processed by the embryology team, who search for viable sperm under the microscope.

When Is TESE Recommended?

• Obstructive azoospermia: TESE is highly effective for men with confirmed obstructive azoospermia
• Failed ejaculation: Men who cannot produce a semen sample through ejaculation
• Prior vasectomy: When vasectomy reversal is not desired or has failed
• Ejaculatory duct obstruction: When the blockage cannot be surgically corrected

TESE Success Rates

For obstructive azoospermia, TESE has sperm retrieval rates of approximately 95 to 100 percent. For non-obstructive azoospermia, conventional TESE retrieves sperm in approximately 25 to 45 percent of cases. This is where Micro-TESE offers a significant advantage.

Micro-TESE: The Gold Standard for Non-Obstructive Azoospermia

Microsurgical TESE (Micro-TESE) represents the most advanced technique available for sperm retrieval in men with non-obstructive azoospermia. By using a high-powered operating microscope, the surgeon can identify and target areas of the testis most likely to contain sperm, resulting in significantly higher retrieval rates compared to conventional TESE.

How Micro-TESE Differs from Conventional TESE

The key difference lies in the use of an operating microscope that provides 15 to 25 times magnification. This allows the surgeon to visually identify seminiferous tubules that appear larger and more opaque, characteristics associated with active sperm production. Instead of taking random biopsies, the surgeon can selectively sample the most promising areas of testicular tissue.

The Micro-TESE Procedure Step by Step

Micro-TESE is performed under general anesthesia and typically takes one to three hours, depending on the complexity of the case. The surgeon makes an incision to expose the testis and then opens the tunica albuginea widely to examine the testicular parenchyma under the operating microscope. Areas with dilated, opaque tubules are carefully dissected and sampled. The embryology team processes these samples in real-time, providing the surgeon with immediate feedback on whether sperm have been found.

Advantages of Micro-TESE

• Higher sperm retrieval rates: Studies consistently show Micro-TESE retrieves sperm in 40 to 63 percent of NOA cases, compared to 25 to 45 percent with conventional TESE
• Less tissue removal: Because sampling is targeted, less testicular tissue needs to be removed
• Reduced complications: Targeted approach means less damage to blood supply and less risk of hematoma
• Better preservation of testicular function: Minimal tissue removal helps maintain testosterone production
• Can identify focal areas of spermatogenesis: Even in testes with predominantly absent sperm production, Micro-TESE can find isolated pockets of active sperm production

Preparing for TESE or Micro-TESE

Proper preparation is essential for optimizing outcomes from sperm retrieval procedures. At GynoLife IVF Center, we follow a comprehensive pre-operative protocol for all patients.

Diagnostic Workup

Before recommending TESE or Micro-TESE, our specialists perform a thorough evaluation including hormone panel assessment of FSH, LH, testosterone, and prolactin levels, genetic testing for Y-chromosome microdeletions and karyotype analysis, physical examination, and review of medical history. This evaluation helps us predict the likelihood of successful sperm retrieval and determine the most appropriate surgical approach.

Hormonal Optimization

In some cases, hormonal therapy before surgery can improve the chances of finding sperm during the procedure. Men with low testosterone levels or elevated estrogen may benefit from several months of hormonal optimization before Micro-TESE. Our specialists carefully evaluate each patient to determine whether preoperative hormonal treatment is advisable.

Lifestyle Recommendations

Patients are advised to maintain a healthy lifestyle in the months leading up to surgery. This includes avoiding smoking and excessive alcohol consumption, maintaining a healthy weight, managing stress, and ensuring adequate sleep. These factors can all influence testicular function and potentially improve the chances of successful sperm retrieval.

What Happens After Sperm Is Retrieved?

Once sperm is successfully retrieved through TESE or Micro-TESE, it is used in conjunction with IVF and ICSI (intracytoplasmic sperm injection) to achieve fertilization. The retrieved sperm may be used fresh on the same day as egg retrieval from the female partner, or it may be cryopreserved for future use.

Fresh vs. Frozen Sperm Use

When possible, coordinating the sperm retrieval with the female partners egg retrieval allows for use of fresh sperm, which may offer slightly higher fertilization rates. However, freezing retrieved sperm through our cryopreservation program provides the security of having sperm available for future cycles without requiring additional surgery.

ICSI with Surgically Retrieved Sperm

Because surgically retrieved sperm is typically available in very small quantities and may have lower motility than ejaculated sperm, ICSI is always used for fertilization. Our experienced embryologists are highly skilled in working with surgically retrieved sperm and achieve excellent fertilization rates.

Recovery After TESE and Micro-TESE

Recovery from both procedures is generally straightforward, though Micro-TESE may require slightly more recovery time due to its more extensive nature.

Immediate Post-Operative Period

Patients can typically return to their accommodation on the same day as the procedure. Ice packs, scrotal support, and pain medication are recommended for the first few days. Most patients experience mild to moderate discomfort that resolves within a week.

Return to Normal Activities

Light activities can usually be resumed within two to three days, while strenuous exercise and heavy lifting should be avoided for two to three weeks. Most patients can return to desk work within a few days, though physically demanding jobs may require a longer recovery period.

Success Stories and Realistic Expectations

While TESE and Micro-TESE have transformed the treatment of male infertility, it is important to maintain realistic expectations. Not all procedures will result in successful sperm retrieval, particularly in cases of non-obstructive azoospermia. However, even in the most challenging cases, Micro-TESE offers hope where none previously existed.

At GynoLife IVF Center, we are transparent about success rates and always discuss alternative pathways, including sperm donation IVF, if sperm retrieval is unsuccessful. Our goal is to provide each patient with the best possible care and the most accurate information to make informed decisions.
