Who Needs TESA or PESA? Signs You May Require Sperm Retrieval

Trying to conceive can become confusing when a semen test shows very few sperm or no sperm at all. In some men, the problem is not necessarily a complete absence of sperm production. Sperm may be present but unable to reach the semen because of a blockage or another reproductive condition.

This is where sperm retrieval procedures may be considered. At a Fertility Centre in Ariyalur, specialists may recommend procedures such as testicular or epididymal sperm retrieval after evaluating the man's medical history, semen analysis, hormone levels, and other fertility findings. The goal is to determine whether usable sperm can be collected for assisted reproductive treatment.

What Does Sperm Retrieval Mean?

Sperm retrieval is a procedure used to collect sperm directly from the male reproductive system when sperm cannot be obtained adequately through ejaculation.

The collected sperm may then be used with assisted reproductive techniques, particularly intracytoplasmic sperm injection (ICSI), where a single sperm is injected directly into an egg.

Sperm retrieval is not automatically required for every man with a low sperm count. The reason for the low or absent sperm count must first be identified.

Who May Need TESA or PESA?

Two procedures commonly considered in selected cases are TESA and PESA.

PESA, or Percutaneous Epididymal Sperm Aspiration, involves using a fine needle to collect sperm from the epididymis. It may be considered when sperm production is present but sperm cannot travel normally through the reproductive tract.

TESA, or Testicular Sperm Aspiration, involves collecting sperm directly from the testicle using a needle. Depending on the underlying condition, doctors may consider it when sperm retrieval from the epididymis is unsuitable or when sperm need to be obtained directly from testicular tissue.

The choice between these procedures depends on the individual's diagnosis rather than simply choosing the procedure that sounds less invasive.

Signs That Sperm Retrieval May Be Considered

There are several situations in which a fertility specialist may discuss sperm retrieval.

1. No Sperm in the Semen

A condition called azoospermia means that sperm are not found in the ejaculate. This can happen because the testicles are producing little or no sperm, or because sperm are being produced but blocked from reaching the semen.

Further testing is important because treatment differs between these two situations.

2. A Blockage in the Reproductive Tract

Previous infections, surgeries, congenital conditions, or certain reproductive problems can sometimes interfere with the normal movement of sperm.

If sperm production is adequate but a blockage prevents sperm from appearing in semen, retrieval directly from the epididymis or testicle may be considered.

3. Previous Unsuccessful Sperm Collection

Some men may have difficulty providing a semen sample or may repeatedly have extremely low sperm numbers. If ejaculated sperm are insufficient for planned treatment, a specialist may consider retrieving sperm directly from the reproductive system.

4. Certain Male Fertility Conditions

Some hormonal, genetic, testicular, or reproductive conditions can affect sperm production or transport. A fertility specialist may recommend additional investigations before deciding whether surgical or needle-based sperm retrieval is appropriate.

How Does the Doctor Decide Between TESA and PESA?

The decision is based on the suspected cause of infertility.

Doctors may review semen analysis results, physical examination findings, hormone tests, previous surgeries, medical history, and sometimes genetic or imaging investigations.

If sperm production appears adequate and the main issue is a blockage, PESA may be considered in appropriate cases. If sperm need to be obtained directly from the testicle, TESA may be considered.

However, these procedures are not interchangeable in every situation. Some men may require a different sperm-retrieval technique depending on their sperm production and diagnosis.

What Happens During the Procedure?

TESA and PESA are generally performed using local anesthesia or another appropriate form of pain control. The area is numbed before the procedure, and a needle is used to collect sperm-containing material.

The retrieved sample is examined by the laboratory to determine whether usable sperm are present. If sperm are found and the couple is undergoing IVF with ICSI, the collected sperm may be prepared for use according to the treatment plan.

The procedure itself may be relatively short, but the overall treatment plan depends on the couple's fertility assessment.

Is Sperm Retrieval Always Successful?

No procedure can guarantee that usable sperm will be found. The likelihood depends largely on the underlying cause of azoospermia or severe male-factor infertility.

This is why proper evaluation before the procedure is important. In some cases, the doctor may recommend additional tests or a different retrieval method rather than proceeding immediately with TESA or PESA.

What Should You Discuss With Your Fertility Specialist?

Before sperm retrieval, ask why the procedure is being recommended, which technique is being considered, what anesthesia will be used, whether the sperm will be used immediately for ICSI, and what alternatives may be available.

It is also useful to discuss recovery, possible discomfort, risks, and what happens if no usable sperm are found.

When Should You Seek an Evaluation?

If repeated semen tests show very low or absent sperm, it is worth having a detailed male fertility evaluation rather than assuming that pregnancy is impossible.

The right treatment depends on finding the reason behind the sperm problem. For some men, sperm retrieval can provide an option for using their own sperm in assisted reproduction.

A consultation at a Fertility Centre in Ariyalur can help couples understand the cause of male infertility, whether sperm retrieval is appropriate, and which treatment approach best fits their individual situation.
