Sperm Retrieval Methods

What is Sperm Retrieval Methods?

IVF clinics in Mexico have become popular for minimally invasive sperm retrieval techniques in which sperm can be obtained from men in almost any situation. Men with infertility issues or have had a vasectomy, a failed vasectomy reversal, or blockages can benefit from sperm retrieval.

Even when sperm production is so low, sperm retrieval has been able to help males with low sperm count build a family.

Methods of Sperm Retrieval

Fertility clinics have various methods of sperm retrieval if medical or religious factors prevent manual stimulation. Collected sperm is washed and analyzed before use in fertility treatments to increase the success rate of pregnancy.

There are four major sperm retrieval procedures including MESA, PESA, TESA & TESE, and MicroTESE which can be used in conjunction with IVF.

MESA is used in cases of severe male infertility. MESA (micro-epididymal sperm aspiration), is performed under general anesthesia. Using microsurgery techniques, fertility specialists make a small incision in the scrotum and remove fluid and tissue. The wound is closed with dis-solvable stitches and swelling and pain subsides within a few days, during which prescribed painkillers may be taken to ease the pain.

Sperm Retrieval Procedure

Sperm Retrieval techniques in Mexico are typically achieved under local anesthetic, IV sedation or general anesthesia to provide complete pain control during the procedure.

A small incision is made in the scrotum, and the testis is exposed. A piece of testicular tissue is then obtained, and passed off to lab personnel for processing. Alternatively, sperm may be obtained from the testicle using needle biopsy or fine needle aspiration. In cases of sperm production disorders, as opposed to obstructive problems, a more extensive procedure for surgical sperm retrieval may be helpful.

Microdissection testicular sperm extraction (TESE), performed under general anesthesia and with the use of the operating microscope, may allow the surgeon to identify even tiny islands of sperm production within the testicles. These areas can then be biopsied and passed off to lab personnel for processing.

Surgically retrieved sperm may be cryopreserved (frozen), and used later for in-vitro fertilization (IVF).

Risks and Side Effects of Sperm Retrieval

Risks and side effects of sperm retrieval may include mild bruising or slight discomfort. Bleeding from incision/aspiration site other secretion coming from incision is normal.

Other risks (although rare) include: infection, nerve damage, damage to blood vessels or epididymis tubules and testicular atrophy.
