Pregnancy. Infertility of unknown origin

What is it and what can be the causes of infertility of unknown origin? When a couple has undergone fertility tests and no apparent cause has been found to prevent conception, it can be said that the infertility is of  a unknown cause. In men, the problem is usually genetic and cannot be detected with a normal sperm analysis;  it is necessary to perform a complementary examination of the semen known as FSH– thus analyzing the genetic structure; making a selection of sperm and proceeding to an in vitro fertilization treatment with ICSI. On the other hand, unsuccessful fertility attempts or repeated abortions may indicate that there is a genetic defect in the ovum,  for which the embryo does not advance. Or in some cases progresses but with a disease, which usually ends in abortion.

So after this type of diagnosis, what tests are important for the woman to do before a treatment? Among others, it is important to check the levels of the Anti-Mullerian hormone in blood to detect the ovarian reserve . A) Yes, • An optimal ovarian reserve value will be at 4-6 ng / ml; but you have to keep in mind that quantity and quality do not always go together. • A normal-satisfactory level will be at 2 ng / ml. • Less than 1 ng / ml is a low hormone level, in these cases it is very difficult for the embryo to advance – and egg donation would be the best option. Of course, you could keep trying with your own eggs as long as they are mature; or get to maturity in the laboratory.
