Male infertility can be emotionally challenging, particularly when tests show a very low sperm count or no sperm in the semen. However, advanced fertility procedures such as Micro-TESE and TESA treatment in Delhi may help retrieve sperm directly from the testicles for use with IVF and ICSI. Choosing the right fertility specialist is important because the appropriate procedure depends on the underlying cause, medical history, hormonal profile and testicular sperm production. This guide explains Micro-TESE, TESA, their differences, treatment process and how specialised male infertility treatment in Delhi can support couples planning a family.
What Are Micro-TESE and TESA?
Micro-TESE and TESA are surgical sperm retrieval procedures. They are generally considered when sperm is absent from the ejaculate or when the sperm count is extremely low.
TESA
TESA stands for Testicular Sperm Aspiration. In this procedure, a fine needle is used to aspirate small quantities of testicular tissue and fluid. The sample is examined by an embryologist to identify viable sperm.
TESA may be considered when:
- Sperm production is present but sperm cannot pass into the semen.
- There is a blockage in the reproductive tract.
- The sperm count is extremely low.
- A less invasive sperm retrieval procedure may be suitable.
- Sperm is required for an IVF-ICSI cycle.
TESA is usually quicker than Micro-TESE and may be performed with local or general anaesthesia, depending on the clinical plan.
Micro-TESE
Micro-TESE means Microsurgical Testicular Sperm Extraction. It is an advanced procedure performed with an operating microscope. The specialist carefully examines the testicular tissue to identify areas that may contain sperm-producing tubules. Micro-TESE is commonly considered in men with non-obstructive azoospermia, a condition in which sperm production inside the testicles is severely reduced or patchy. Since the procedure allows targeted tissue collection, it may help avoid unnecessary removal of healthy testicular tissue. Surgical sperm retrieval procedures are used differently depending on whether azoospermia is caused by a blockage or by reduced sperm production. TESA and TESE may be considered in certain obstructive cases, while Micro-TESE is commonly used when sperm production is impaired.england.nhs+1
When Is Micro-TESE or TESA Recommended?
A fertility specialist may discuss TESA or Micro-TESE after a detailed evaluation. The recommended procedure is not the same for every patient.
These treatments may be considered in cases such as:
- Azoospermia or zero sperm count.
- Severe oligospermia, meaning a very low sperm count.
- Non-obstructive azoospermia.
- Obstructive azoospermia.
- Previous unsuccessful sperm retrieval.
- Ejaculatory or reproductive tract disorders.
- Certain hormonal or genetic conditions.
- Sperm retrieval required for IVF and ICSI.
Before recommending treatment, the doctor may review semen analysis reports, hormone tests, ultrasound findings, previous surgeries and the couple’s fertility history. In some cases, genetic testing may also be considered. A careful diagnosis helps the specialist select between TESA, TESE, Micro-TESE or another treatment option.
Micro-TESE vs TESA
The choice between TESA and Micro-TESE should be based on the diagnosis rather than on the procedure’s name alone. A specialist in male infertility can explain which technique is more suitable after reviewing the patient’s reports.
How Does the Treatment Work?
1. Initial consultation
The process begins with a consultation involving a fertility specialist or reproductive medicine team. The doctor may discuss the couple’s medical history, fertility goals and previous treatment.
2. Diagnostic assessment
The evaluation may include repeat semen analysis, hormone testing, testicular examination and imaging where required. These tests help identify whether the problem relates to sperm production, obstruction or another condition.
3. Choosing the sperm retrieval method
Based on the findings, the specialist may recommend TESA, Micro-TESE or another procedure. The plan may also include IVF-ICSI because retrieved sperm is often used directly for fertilisation in the laboratory.
4. Sperm retrieval procedure
During TESA, a fine needle is used to collect testicular tissue or fluid. During Micro-TESE, a small incision is made and the testicular tissue is examined under magnification so that areas more likely to contain sperm can be selected.
5. Laboratory examination
The sample is transferred to the embryology laboratory for immediate analysis. If viable sperm is identified, it may be used for ICSI or preserved through sperm freezing, depending on the treatment plan.
6. Recovery and follow-up
The doctor provides instructions regarding rest, medication, wound care and follow-up. Recovery varies according to the procedure, anaesthesia and individual health.
Role of IVF and ICSI
Sperm retrieved through TESA or Micro-TESE may be limited in number and movement. For this reason, it is commonly used with intracytoplasmic sperm injection or ICSI. In ICSI, an embryologist injects a single sperm into a mature egg. The resulting embryos may then be monitored and transferred as part of an IVF treatment plan. The fertility team will explain whether fresh or frozen sperm is appropriate and how the sperm retrieval procedure fits into the couple’s IVF cycle. The outcome depends on several factors, including the presence of viable sperm, egg quality, the female partner’s reproductive health, embryo development and overall medical history. No clinic can guarantee a pregnancy or a specific treatment outcome.

Frequently Asked Questions
1. What is Micro-TESE treatment in Delhi?
Micro-TESE is a microsurgical sperm retrieval procedure used to search for viable sperm within the testicular tissue. It is often considered in cases of non-obstructive azoospermia and may be combined with IVF-ICSI.
2. Is TESA suitable for zero sperm count?
TESA may be suitable for some men with zero sperm in the semen, but its suitability depends on the cause of azoospermia. A fertility specialist must evaluate whether the problem is related to obstruction or reduced sperm production.
3. Which is better, TESA or Micro-TESE?
Neither procedure is universally better. TESA may be suitable in selected cases, while Micro-TESE may be considered when sperm production is severely reduced. The correct option depends on the individual diagnosis.
4. Can sperm retrieved through Micro-TESE be used for IVF?
Yes. If viable sperm is found, it may be used with ICSI during an IVF cycle. The embryology team decides how the retrieved sperm should be processed and used.
5. How long does recovery take after TESA or Micro-TESE?
Recovery differs according to the procedure and the patient’s health. Many patients experience temporary tenderness or swelling and receive personalised instructions regarding rest, medication and physical activity.
6. How can I find the best male infertility treatment in Delhi?
Look for a clinic with experienced fertility specialists, male infertility expertise, advanced sperm retrieval facilities, a qualified embryology team and transparent treatment planning. A detailed consultation is the best way to understand your options.
