Could fertility problems have a genetic origin?

To be able to diagnosis fertility problems there are a number of test that allow us to know if there is a genetic cause responsible of the fertility problem. For the study of the masculine factor, the karyotype study, microdelection of the Y chromosome and cystic fibrosis study could justify the low number or the absence of spermatozoids. For women, the karyotype study, the screening of the Fragile X Syndrome, those could be the cause of repeated miscarriages and low ovarian reserve, respectively.
