What are PESA, TESA, and TESE?

The primary objective of these techniques is to retrieve sperm via surgical procedures or aspiration when sperm is either absent or insufficient in the ejaculate. The retrieved sperm can typically be utilized on the same day or, if considered suitable, frozen and preserved, depending on the laboratory capabilities of the facility.

In which circumstances should it be taken into account?

Surgical sperm retrieval techniques may be considered in the following circumstances (the ultimate decision will be made following expert assessment):

The lack of sperm in the semen, known as azoospermia, and the verification of this finding through a subsequent semen analysis.

Suspected obstruction of the sperm duct (e.g., prior infection or surgery, absence of the vas deferens)

Situations in which low sperm production is suspected (based on hormonal or testicular findings)

Inability to acquire an ejaculate sperm sample or inadequate quality during an IVF/ICSI procedure.

The failure to acquire sperm through previously attempted methods and the strategizing of the subsequent approach.

Procedure: Overall Steps

While there may be variations in implementation among centers, the process typically includes the following steps:

Initial evaluation — Urological examination, semen analysis, hormone assessments (FSH/LH/testosterone, etc.), ultrasound, and genetic testing if required.

Planning involves deciding on the method (PESA/TESA/TESE) to be utilized, selecting the appropriate anesthesia, and coordinating it with the IVF/ICSI schedule.

Consent and preparation — Evaluation of medications utilized, assessment of bleeding risk, and compliance with center guidelines such as pre-procedure fasting and cleansing.

Procedure — Sample collection through needle aspiration or a minor surgical procedure, based on the selected method.

Laboratory examination — Identifying sperm in the sample; if suitable, assessing options for immediate use or cryopreservation.

Discharge and follow-up — Same-day discharge is typical; a plan for pain and swelling management and control is created.

Possible Benefits and Drawbacks

Recovery and Key Considerations

Recovery time can differ based on the method employed and personal circumstances. The written instructions from your center are essential.

First 24–48 hours — Rest, scrotal support (loose but supportive underwear), and the use of prescribed pain medication.

Swelling or bruising — Can range from mild to moderate; seek medical assistance if swelling or bruising worsens significantly.

Hygiene — Adhere to dressing and showering guidelines if there is a cut; refrain from areas like swimming pools and Turkish baths for some time.

Physical activity — Resuming heavy lifting and vigorous exercise should be conducted in accordance with the timeline advised by your physician.

Sexual activity — The appropriate timing for resuming varies based on the individual and the procedure; it is important to adhere to the physician's recommendations.

Questions to Consider When Organizing Treatment in Georgia

The subsequent questions can assist in making the center and team selection process more transparent:

Who will conduct the urology/andrology assessment, and what qualifications do they possess?

Which method appears to be more suitable for my definition: PESA, TESA, TESE, or micro-TESE? What is the reason?

What kind of anesthesia will be administered for the procedure, and what is the plan for discharge on the same day?

If sperm is detected, will it be utilized fresh? What are the options for freezing and the success rates for freezing and thawing?

What is the experience of the embryology laboratory with ICSI and what are its quality standards?

What are the precise requirements for genetic testing (if needed) and hormone assessments?

What complications may arise, and what is the plan for managing them?

What are the total cost components (procedure, anesthesia, laboratory, freezing/storage, medications, follow-up)?

If no results are achieved, what would the subsequent step be?

Commonly Asked Questions

Is the procedure painful? The level of discomfort experienced during the procedure typically depends on the type of anesthesia administered. While pain is generally managed effectively, some tenderness or discomfort may persist for a few days following the procedure; it is advisable to adhere to the center's recommendations for pain management.

2) Is the retrieval of sperm guaranteed? No. The likelihood of obtaining sperm differs based on the individual, the underlying condition, and the selected technique. Consequently, it is essential to discuss realistic expectations and alternative options prior to the procedure.

3) Does acquiring sperm ensure pregnancy? Pregnancy is influenced by numerous factors beyond sperm collection, such as egg quality, embryo development, uterine conditions, and more. Acquiring sperm alone does not ensure pregnancy.

4) Is it possible to use frozen sperm at a later time? Most facilities permit the use of sperm after it has been frozen and thawed under suitable conditions; however, each sample and laboratory procedure varies. Inquire with your facility regarding their freezing-thawing protocols and success rates.

5) When is it appropriate for me to return to work or travel after the procedure? For straightforward procedures, a swift return to work is feasible; however, recovery times can differ from person to person. It is essential to plan based on the doctor's advice, particularly for extended trips and jobs that require physical exertion.

Conclusion

PESA, TESA, and TESE are significant methods for acquiring sperm in IVF/ICSI procedures when sperm is lacking or inadequate in semen. Choosing the right approach necessitates a careful evaluation of precise diagnosis, professional expertise, laboratory capabilities, and personal risks.
