TESA

Testicular Sperm Aspiration (TESA) is a medical procedure used to retrieve sperm directly from the testicles of men who have difficulty producing sperm in their ejaculate. This procedure is typically performed as part of fertility treatments such as in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) when natural conception is not possible due to issues like obstructive azoospermia, non-obstructive azoospermia, or other conditions that result in a lack of sperm in the ejaculate.

Testicular Sperm Aspiration (TESA) is typically recommended for men who have certain conditions or factors that make it difficult for them to produce sperm in their ejaculate. The right candidate for TESA generally includes individuals who meet the following criteria:

• Azoospermia: Azoospermia is the medical condition where no sperm is present in the ejaculate. There are two main types:

• Obstructive Azoospermia: In this condition, sperm production is normal, but there is a physical blockage preventing sperm from reaching the ejaculate. TESA can be used to retrieve sperm from the testicles in such cases.

• Non-Obstructive Azoospermia: In this condition, there is an issue with sperm production in the testicles. TESA may also be used to attempt sperm retrieval, although success rates can vary.

• Prior Vasectomy: Men who have undergone a vasectomy and now wish to father a child may opt for TESA to retrieve sperm for use in fertility treatments.

• Failed Previous Sperm Retrieval Procedures: If other sperm retrieval techniques like testicular biopsy or percutaneous epididymal sperm aspiration (PESA) have failed to yield sperm, TESA may be considered as an alternative.

• Genetic or Medical Conditions: Some genetic or medical conditions can result in a lack of sperm in the ejaculate. TESA may be recommended in such cases to retrieve sperm for assisted reproductive techniques.

• Prior Radiation or Chemotherapy: Men who have undergone radiation or chemotherapy that affected sperm production may require TESA to retrieve sperm for fertility preservation.

• Unexplained Male Infertility: In cases of unexplained male infertility, where the cause of infertility is not clear, TESA may be considered as a diagnostic tool to determine if sperm can be found in the testicles.

• Desire for Genetic Parenthood: Couples or individuals who desire to have biological children and are pursuing assisted reproductive techniques like in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) may opt for TESA to obtain sperm for fertilization.

The procedure is typically performed using a fine needle and syringe to aspirate sperm directly from the epididymis. Ultrasound may also be used to guide the needle to the appropriate location.
