The most striking development in the field of severe male infertility in recent years is undoubtedly seen in men with no sperm cells in the semen. If the egg channels are blocked for some reason or the production of the ovaries is insufficient, another source should be consulted to obtain sperm cells. If the ovarian ducts are obstructed or congenitally absent, sperm cells are removed from the channels and microinjection is performed with these cells.
In the absence of obstruction, the problem is more complicated. In these cases, production of the male ovary may be very limited, though very limited. A large number of small parts are taken from various parts of the ovary to look for sperm cells in these parts. Fertilization and pregnancy rates in men with semen are reached with both techniques.
Thus, the number of couples who do not benefit from treatment opportunities is reduced. The fact that the sperm cell comes from the semen, ovarian channels or directly from the ovaries does not affect pregnancy rates. The only obstacle today is the quality of the female egg. Experts state that the most important factor determining quality is the age of the woman. While years do not affect sperm cell quality, it has negative effects on female ovaries and pregnancy rates decrease with female age.
