How does the woman's age affect sterility?

Age in women, affects their reproductive capacity. So, when studying in epidemiological analysis, a clear decrease in reproductive capacity starts after age 35 years. After age 40 years this decreases gets higher.
At this age, the quality oocyte is the main cause reproductive decline.

Studies in non-fertilized oocytes and analysis of embryos through in situ- hybridization have shown that the rate of chromosomal abnormalities increases significantly with age. These studies are corroborated by the evidence that the chromosomal abnormalities in aborted fetuses, babies and embryos are more frequent with the increase in the woman’s age.

Does stress have effects on the infertile ability for couples?

There is no conclusive works. Some investigations support the fact that to confront the treatment of infertility without "defeatist thinking" encourages the result.

One of the consequences of infertility is the increase of stress and anxiety in the involved couples. We understand that these problems must be addressed and treated by mutual agreement. We have the means to help them to find the right strategy to solve it (counseling program).

How long must we wait to start treatment?

The initiation of treatment will be started immediately after the conclusion of the study about the sterility causes. Once we have gathered all the information to conduct clinical diagnosis, we will meet with the pair to suggest the type of treatment.
Once done, and depending on the day of menstrual cycle, we will begin the treatment that has been assessed.

If the sperm is "normal" can we rule out the male as cause of sterility of the couple?

A normal sperm count guides us towards a normal male factor. Sometimes, in semen with limit values, we are forced to perform a second semen sample to check possible variations.

We consider a normal sperm count when, with a normal volume ejaculate, the male has 20 million sperm per milliliter, with a 50% of useful sperm and a rate of more than 15% normal morphological sperm.

In case of a sterility of unknown causes, and failed treatments, we must make some additional tests, in men, to rule out genetic abnormalities in sperm that may be cause of poor embryo quality.
Additional tests are: the study of sperm DNA fragmentation and the study of meiosis.
