TESA/PESA

TESA and PESA are the sperm retrieval techniques for males having less production of sperm.

The sperm can be less in number (Oligospermia), less mobile (Asthenospermia) or completely absent in the semen (Azoospermia). These sperm disorders make it difficult for a person to make her partner pregnant and thereby result in infertility. However, this can be treated by using such sperm retrieval techniques, isolating the healthy sperm and later using them for IVF (in vitro fertilization). Sperm extraction techniques like TESA, PESA, MESA and TESE are performed on different levels for male infertility treatments.

PESA Treatment (Percutaneous Epididymal Sperm Aspiration)

This technique is the most simple of all. It is performed in the cases where the testicle is producing sperm normally but they are unable to come out. It can be due to any blockage in the vas deferens. In this technique, a needle is passed into the head of the epididymis and the fluid is aspirated. This fluid is then sent to the lab where the sperms are isolated from the fluid and then used for IVF or ICSI.

TESA Treatment (Testicular Sperm Aspiration)

This is similar to the PESA technique as it doesn’t involve any incision too where only a needle is needed. The fluid is aspirated from the testicles by inserting a needle. The fluid is collected in the syringe which is attached to the needle. This is then sent to the lab for IVF and ICSI.

There is another sperm retrieval procedure known as Micro TESE or Micro TESA that is used in the cases of non-obstructive Azoospermia.

We at Ferticity Fertility Clinics perform these sperm retrieval procedures in routine. To know more about Male Infertility and Treatment Options Available by the best Tesa IVF centre in Delhi talk to our Fertility Specialists today and get your doubts cleared.

Frequently Asked Questions

PESA is a procedure that includes inserting a tiny needle into the epididymis via the skin to retrieve sperm. TESA, on the other hand, entails inserting a fine needle directly into the testes and retrieving a small number of seminiferous tubules.

Men dealing with any of these issues can benefit from PESA/TESA:

Poor sperm production due to testicular issues. Genetic abnormalities, past infection (e.g. mumps), and maldescended testes can all contribute to this.
A blockage of the genital tract that is not reversible (possibly caused by previous infection, trauma or surgery)
The vas deferens have a congenital absence (absence from birth), which is frequent in cystic fibrosis carriers.
History of vasectomy or an unsuccessful vasectomy reversal.

Patients with the TESA treatment frequently experience discomfort and swelling following the surgery. Men suffering from non-obstructive and obstructive Oligozoospermia can also benefit from the PESA and TESA techniques.

The procedure takes about 20-30 minutes. The recovery is shorter and significantly less painful. Open testicular surgery may require a recovery period of nearly a week.

IVF treatment using PESA or TESA sperm has a similar success rate to IVF/ICSI using fresh semen produced.
