Sperm Retrieval TESA TESE in Cyprus IVF
Advanced Options for Azoospermia and Severe Male Factor Infertility
Male factor infertility can sometimes involve azoospermia, meaning no sperm is found in the ejaculate. While this diagnosis can feel overwhelming, modern sperm retrieval techniques make it possible for many men to become biological fathers—especially when combined with ICSI (intracytoplasmic sperm injection) in a Cyprus IVF program.
Two of the most common “sperm search” procedures are TESA and TESE. These methods aim to retrieve sperm directly from the testicle so it can be used in IVF/ICSI.
What Are TESA and TESE?
TESA (Testicular Sperm Aspiration)
TESA is a minimally invasive sperm retrieval technique where sperm is aspirated from the testicle using a fine needle. It is usually quicker and involves less tissue removal.
TESA is most often considered when:
-
Azoospermia is suspected to be obstructive (blockage-related)
-
The testicle is expected to contain sperm production, but sperm cannot reach the semen due to a blockage
-
A less invasive approach is preferred as a first step
TESE (Testicular Sperm Extraction)
TESE is a surgical sperm retrieval technique where a small piece of testicular tissue is extracted and examined to find sperm.
TESE is commonly considered when:
-
Azoospermia may be non-obstructive (sperm production is limited)
-
Previous needle aspiration did not find usable sperm
-
The medical team wants to increase the chance of sperm recovery by evaluating more tissue
Micro-TESE (Microsurgical TESE)
In some cases, especially in non-obstructive azoospermia (NOA), clinics may recommend Micro-TESE, where a surgeon uses an operating microscope to locate areas most likely to contain sperm. This approach can improve retrieval chances in selected patients and may reduce unnecessary tissue removal.
Why Are These Procedures Important in Cyprus IVF?
Many couples travel for Cyprus IVF because treatment planning can be organized efficiently, and advanced male infertility techniques can be integrated into one coordinated program. When sperm is retrieved through TESA or TESE, it can be used for:
-
ICSI (most common, because sperm numbers are often low)
-
Sperm freezing for future IVF cycles (when sufficient sperm is found)
-
Avoiding repeated surgical procedures when freezing is successful
Understanding Azoospermia: Obstructive vs Non-Obstructive
Obstructive Azoospermia (OA)
Sperm is usually produced normally, but a blockage prevents it from appearing in the semen. Common causes include:
-
Prior vasectomy
-
Congenital absence of the vas deferens
-
Infection-related blockage
-
Surgical or anatomical issues
In OA, retrieval success is typically higher because sperm production is often preserved.
Non-Obstructive Azoospermia (NOA)
Sperm production is reduced or irregular. Causes may include:
-
Genetic factors
-
Hormonal issues
-
History of undescended testicles
-
Testicular failure patterns
-
Severe varicocele in some cases
In NOA, retrieval is more complex, and methods like TESE or Micro-TESE may be more appropriate.
Who May Need TESA or TESE?
TESA/TESE may be considered in Cyprus IVF programs for men who have:
-
Azoospermia confirmed on repeated semen analyses
-
Very severe oligospermia (extremely low sperm count) where collecting enough sperm is difficult
-
A history suggesting obstruction
-
Prior failed attempts with ejaculated sperm
-
Need for sperm retrieval on the same day as egg collection for IVF/ICSI
A proper evaluation is essential before choosing the technique.
Pre-Procedure Evaluation Before Sperm Retrieval
Before planning TESA or TESE, fertility specialists often review:
1) Repeat Semen Analysis
Azoospermia must be confirmed, typically with more than one test.
2) Hormonal Testing
Common labs include FSH, LH, total testosterone, prolactin, and sometimes additional markers. Hormones can help estimate sperm production potential.
3) Scrotal Ultrasound (When Needed)
Imaging may help assess testicular size, varicocele, or structural issues.
4) Genetic Testing (When Indicated)
In azoospermia, genetic evaluation may be recommended, especially before IVF/ICSI, to understand potential inherited factors.
How TESA Is Performed (Step by Step)
-
Preparation
The procedure is planned with the IVF timeline (especially if fresh sperm is needed). -
Anesthesia
Local anesthesia is common; sedation may be used depending on protocol. -
Needle Aspiration
A needle is inserted into the testicle and tissue fluid is aspirated. -
Laboratory Search
Embryology/andrology specialists examine the aspirate for live sperm. -
Use or Freezing
If sperm is found, it can be used immediately for ICSI or frozen for future use.
How TESE Is Performed (Step by Step)
-
Preparation and Timing
TESE can be scheduled before IVF or coordinated with egg collection. -
Anesthesia
Local anesthesia, sedation, or short general anesthesia may be used. -
Small Incision and Tissue Extraction
The surgeon removes a small piece of testicular tissue. -
Laboratory Processing
The tissue is carefully processed to identify viable sperm. -
Use in ICSI or Freezing
Retrieved sperm is typically used for ICSI. Excess sperm may be frozen when possible.
How Retrieved Sperm Is Used in IVF/ICSI
In most cases, surgically retrieved sperm is used with ICSI, where a single sperm is injected into each mature egg. This is often necessary because:
-
The number of sperm retrieved may be limited
-
Sperm motility may be reduced
-
The sample may contain sperm within tissue fragments
Success Rates: What Affects the Chance of Finding Sperm?
Sperm retrieval outcomes vary widely. Key factors include:
-
Whether azoospermia is obstructive or non-obstructive
-
Testicular volume and hormone profile (especially FSH)
-
Underlying medical or genetic causes
-
Previous surgeries or conditions (e.g., undescended testicle history)
-
Technique selected (TESA vs TESE vs Micro-TESE)
-
Lab expertise in processing and identifying sperm
Important note: Finding sperm does not automatically guarantee pregnancy, as IVF success also depends on egg quality, embryo development, and uterine factors.
Risks and Recovery After TESA/TESE
Common, usually mild effects
-
Temporary discomfort or aching
-
Swelling or bruising
-
Mild bleeding
Less common risks
-
Infection
-
Hematoma (collection of blood)
-
Persistent pain (rare)
-
Testicular tissue impact (risk is generally low when performed appropriately, but varies by technique and tissue amount)
Recovery often includes:
-
Short rest period
-
Supportive underwear
-
Avoiding heavy activity for a few days
-
Following medical instructions closely
Frequently Asked Questions
Is sperm retrieval painful?
With proper anesthesia, most men experience minimal pain during the procedure. Mild soreness afterward is common.
Can sperm be frozen after TESA/TESE?
Yes—if enough viable sperm is found. Freezing may reduce the need for repeat procedures in future cycles.
Is TESA or TESE better?
It depends on the diagnosis. TESA is often used first in suspected obstructive cases. TESE/Micro-TESE may be preferred in non-obstructive azoospermia or after failed aspiration.
Can TESE be done the same day as egg collection?
Yes. Many Cyprus IVF programs coordinate retrieval with the IVF timeline, depending on medical planning and logistics.
Conclusion: TESA and TESE as Powerful Tools in Cyprus IVF
For men with azoospermia or severe male factor infertility, TESA and TESE provide real possibilities to retrieve sperm directly from the testicle and use it with ICSI. In a well-organized Cyprus IVF plan, sperm retrieval can be coordinated efficiently, and retrieved sperm may be frozen to support future attempts.
Because every case is unique, the most accurate approach is a personalized evaluation including semen analysis, hormones, and medical history—so the medical team can choose the most appropriate retrieval strategy.
