A man can become a father with the help of the IVF TESE (testicular sperm extraction) technique even if a series of spermograms showed the absence of viable spermatozoa in the ejaculate. This is a microsurgical operation that allows getting sperm directly from the seminiferous tubules of the testis. Under the control of high-precision optical equipment, the healthiest germ cells are secreted. They can be used for fertilization within 72 hours or subjected to cryopreservation. Read this article to learn more about IVF with TESE.
Reasons for TESE
The absence of sperm in semen can be explained by several reasons:
- blockage of sperm channel
- congenital absence of sperm channel
- hormonal disorders
- genetic problems (the gene responsible for sperm production is located on the Y chromosome, and problems in these genes affect sperm production)
- medications (especially those used to treat cancer, which can completely stop sperm production)
- infection (like parotitis).
How does the TESE Method Do?
The IVF TESE procedure is performed under anesthesia with the help of a microscope. The cells are taken from 4 different places from both testicles. The resulting cells undergo a series of examinations, and living sperm cells are isolated.
The living cells will be used for in vitro fertilization by the aid of a microinjection method. A cryo method can be used to freeze the sperm cells. Freezing does not violate the sperm quality. Besides, this procedure helps avoid repeated interventions for those couples who want to have a second child. IVF with TESE has success rates of more than 77%.
What Does a Patient Need to Do after the Operation?
A patient has to be prepared to follow all doctor`s prescriptions and advice. The most common among them are:
- A patient can drink water only 3 hours after the surgery.
- Having a shower is allowed on the 5th day after the operation.
- Sexual contacts are prohibited for 1 week.
- In the case of pain, a patient can take painkillers.
- If there is redness, swelling or bleeding observed, a patient has to see a doctor.
TESA and PESA: What Is the Difference?
Not only TESE IVF can give a man the joy of fatherhood, but also PESA and TESA IVF treatment. TESA (testicular sperm aspiration) is the most popular method. The procedure is performed under intravenous anesthesia. It takes a quarter of an hour, and after an hour, the patient can return home. The course of laboratory research involves 5-6 procedures. The advantages of the method include low cost, the absence of an open biopsy and microsurgery. However, the TESA IVF success rate is relatively low in comparison with other methods.
PESA (percutaneous sperm aspiration) involves piercing of epididymis. The procedure is mostly performed under local anesthesia. The initial rehabilitation (pressure on the injection site, primary bondage) takes an hour, while the full rehabilitation (bondage, cold applications, special underwear) takes a day.
The TESE, PESA, and TESA IVF options will help a couple experience the happiness of parenthood. However, both of them have to follow all doctor`s advice and restrictions.
