Organs Organs Azoospermia WHAT IS AZOOSPERMIA - Azoospermia 1 2 3 INTRACYTOPLASMIC SPERM INJECTION (ICSI) WHAT IS IT? AZOOSPERMIA
The Process by Definition: Injection by a micro-needle of a single sperm into an egg that has been surgically removed from an ovary followed by transfer of the egg to an incubator where fertilization takes place and then by implantation of the fertilized egg into a female’s uterus.
During ICSI the sperm don’t have to travel to the egg or penetrate the outer layers of the egg. THE PROCEDURE •LUTEAL PHASE – This phase stimulates the progesterone, which will further aid in the maintenance of the inner lining of the uterus. OTHER ALTERNATIVES If this technique does not remove enough sperm, the doctor can try another tactics... •Gradient Sperm Washing, Filtration and Improvement
•Testicular Sperm Aspiration (Extraction) MESA, PESA, TESA, Including for Failed Vasectomy Reversal PESA, TESA, MESA Sperm can be collected directly from the epididymis (a narrow tube inside the scrotum, where sperm are stored and matured) using a type of fine syringe. This is known as ‘percutaneous epididymal sperm aspiration’ or PESA.
Also there is MESA known as ‘Microsurgical Epididymal Sperm Aspiration’. It involves careful dissection of the epididymis under the operating microscope and an incision of a single tubule.
Sperm can also be retrieved from the testicles, a process known as ‘testicular sperm aspiration’ or TESA. Azoospermia is the complete lack of sperm in the ejaculate. There are two different types of azooprermia:
-Obstructive Azoospermiawhich is where there is a blockage in either the Vas Deferens or the Epididymis that prevents the sperm form mixing with the semen.
-Non-Obstructive Azoospermia is where there is a problem with sperm production within the body. CAUSES OF AZOOSPERIMA SPERM PRODUCTION PROBLEMS SPERM TRANSPORT PROBLEMS The failure of the testis to produce sperm is often the result of:
-Hormonal abnormalities: sometimes the body may not produce enough of certain hormones that are needed in the sperm making process.
-Cryptorchidism: Which is where the testes have not descended properly and are not able to produce sperm.
-Vascular Trauma which is where there is trauma to the testes or the blood vessels within the testes. Varicocele causes veins in the testes to enlarge and become swollen and as a result, blood pools in the testes, impairing sperm production Sperm transport problems are often caused by:
-Vasectomy: A procedure that introduces a cut or blockage into the vas deferens which prevents the sperm from mixing with the ejaculate.
-Congenital absence of Vas Deferens: born without the vas Deferens
-Infection: infections such as STDS, can cause blockages in the epididymis or the Vas Deferens. THANK-YOU! Kyle and Trudy have been trying to have a baby for over one year. Both of them have been to fertility specialists, and Kyle was diagnosed as having azoospermia. This condition was caused by a congenital absence of the vas deferens. Trudy and Kyle decided to try intracytoplasmic sperm injection (ICSI) using a sperm donor. The procedure resulted in a successful pregnancy for Trudy.
