Testicular Sperm Extraction (TESE)

Department of Testicular Sperm Extraction (TESE)

Microscopic testicular sperm extraction (microTESE) is a procedure that takes sperm directly from the testicular tissue of a man’s reproductive system. If a man can’t release or make enough healthy sperm naturally, this medical procedure may be recommended for fertility reasons (to enable the man to father a child). The testicular tissue is found in the two testes, where the sperm is made. The testes are found inside the scrotum, the small sac behind and under the penis.

Before

Before undergoing Testicular Sperm Extraction (TESE), various tests may be conducted to assess the reproductive health of the male. Common tests include:

1.Semen Analysis: Evaluates sperm count, motility, and morphology to assess the quality of sperm in the ejaculate.

2.Hormonal Tests (e.g., Testosterone): Measures hormone levels to assess the function of the testes and overall reproductive health.

Types

1.Conventional TESE: Involves the surgical removal of a small piece of testicular tissue, followed by the extraction of sperm from the tissue in the laboratory.

2.Microdissection TESE (Micro-TESE): A more precise and less invasive technique where the surgeon uses an operating microscope to identify and selectively extract areas of the testes likely to contain sperm.

Treatment

A urologist, a doctor who specializes in the male and female urinary tract and male reproductive organs, typically performs the procedure by making a few small cuts in the testicle and removing a small amount of tissue. Once the tissue is removed from the body, it is examined under a microscope to look for sperm. If found, the sperm can be used right away to fertilize an egg, or the sperm cells can be frozen, stored and then thawed at a later time to be used for infertility treatment.

The procedure is usually performed in the operating room with the patient under general anesthesia. A single incision is made in the middle of the scrotum. A microscope is used to help see the fine tubules of the testis that may contain sperm. All sutures (stitches) that are used dissolve on their own. The patient is able to go home the day of the procedure, and should be able to resume normal activities within one to two weeks.
