TESA vs PESA: Which Is Better for Male Infertility?

November 24, 2025 Infertility

---

When a man’s semen test shows no sperm, it brings a lot of fear. Most couples feel lost and think pregnancy won’t be possible. But that’s not true. Medicine has come a long way. Today, sperm can be taken directly from the body using two small procedures called TESA and PESA. These have helped many couples at Sunflower Hospital become parents.

Understanding Why These Procedures Are Needed

Sometimes the body makes sperm, but they don’t come out in semen. There might be a blockage, injury, or very low sperm production. In such cases, doctors first do a few male infertility tests to understand the reason. If sperm are being produced inside but not seen outside, we use TESA or PESA to collect them directly.

What Is TESA

TESA means Testicular Sperm Aspiration. It’s a small and simple procedure. Local anesthesia is given, so there’s no pain. With a thin needle, the doctor takes a small bit of tissue from the testis and checks it under a microscope. Sperm found in that tissue are then used later for treatment.

TESA helps when sperm production is very low or blocked inside the testis. The process is quick, safe, and men can go home the same day.

What Is PESA

PESA means Percutaneous Epididymal Sperm Aspiration. It’s also done under local anesthesia. Here, the sperm are taken from a tiny tube near the testis called the epididymis, where sperm are stored after they are made.

This is used when sperm are being produced normally but can’t come out because of a blockage. It’s a quick process, doesn’t need stitches, and recovery is easy.

How TESA and PESA Differ

TESA and PESA look similar but are done in different places. In TESA, sperm come directly from the testis. In PESA, sperm come from the tube beside it. TESA is helpful when sperm production is low, and PESA works well when sperm are fine but stuck because of a blockage.

Both are short, safe, and almost painless. The doctor chooses which one fits best after checking reports, hormone levels, and male infertility causes.

Which One Is Better

There’s no fixed answer. Each man’s situation is different. For some, PESA gives enough sperm for treatment. For others, TESA works better. The aim is always to collect healthy sperm that can be used for pregnancy.

At Sunflower Hospital, the decision is made after a full discussion with the couple. We explain everything in detail so they feel confident and supported.

The Hope Behind the Procedure

TESA and PESA are small steps but bring big change. Many men who had lost hope are now fathers.

At Sunflower Hospital, we treat every man with privacy, care, and respect. Male infertility causes can be many, but with the right diagnosis and low sperm count treatment, most couples succeed. Infertility is not an ending. With science and compassion, it becomes a new beginning.
