Sperm Retrieval Procedures (TESA/PESA)
Sperm retrieval procedures are often used to treat male infertility issues caused by problems with sperm production or sperm delivery. Only men with no sperm in their ejaculate (azoospermia) need to have sperm retrieved directly from the testis or epididymis.

At Nordica Fertility Centre, our SRP service allows men with low (or zero) sperm count fulfil their dreams of parenthood. There are two main types of Azoospermia: ‘Obstructive Azoospermia’ and ‘Non-Obstructive Azoospermia’.
  • Obstructive Azoospermia: Sperm produced from the testis are unable to be ejaculated, due to a blockage in the reproductive track. Here, patients can still ejaculate seminal fluid but with complete absence of sperm. The blockage is usually at the level of sperm transport tubules and can be caused due to repeated infections, vasectomy or previous injury.
  • Non-obstructive Azoospermia: This occurs when the testicles fail to produce sperm, leading to very little or no sperm during ejaculation. This can be confirmed based on testicle size by a special test called Testicular biopsy on the ultrasound scan.

Sperm Retrieval Techniques

There are several techniques used to retrieve sperm from the reproductive organ. At Nordica we offer the following:

Testicular Sperm Aspiration (TESA)

This technique is performed for men with obstructive azoospermia. A needle is inserted into the testis and tissue samples are obtained by gentle suction and examined under the microscope.Surgically retrieved sperm are immature and therefore not capable of fertilization by conventional means except by ICSI. After the procedure, firm scrotal support will be recommended as well as regular painkillers like paracetamol as you may feel some discomfort and bruising for about 48hrs.

When should Sperm Retrieval be considered?

SRP should be considered if: 

  • You have certain genetic conditions that may affect sperm production.
  • You have been diagnosed with low or zero sperm count
  • You have previously undergone vasectomy (A minor surgery to blocks sperm from reaching the semen that is ejaculated from the penis) at any point in time
  • You have a history of sexually transmitted infections like chlamydia.
  • You have congenital absence of the vas deferens (men born without the tube that drains the sperm from the testicle)
