What is Azoospermia?

Azoospermia means there is no sperm cells in a man’s semen. There are two types of azoospermia which are obstructive and non-obstructive azoospermia. Chemotherapy or radiation treatments, genetical disorders, endocrine abnormalities, infection or inflammation of reproductive tract, and retrograde ejaculation may be the reasons of azoospermia.

According to semen analysis and hormone profile, doctors will suggest a therapy for the treatment of azoospermia. Surgical sperm retrieval methods such as PESA, TESA, TESE, Micro TESE are also options to get sperm cells. These sperm cells are used in ICSI method to fertilize oocytes.

In some cases there has been no mature sperm cells found in sperm retrieval procedures. Doctors may give you a medication therapy or repeat the sperm extraction procedure. Now with Round Spermatid Injection (ROSI) technique, round cells also can be used in fertilization to make an embryo.

Sperm cells and oocytes are activated by a special technique with electrofusion and this technique increased the fertilization rate. This technique known as the technique of round spermatit injection and it’s a breakthrough one.
