Unexplained infertility is not easy to diagnose and, therefore, it is necessary to perform various complementary tests. Among them, the karyotype would be a good option for detecting possible alterations at the chromosomal level such as duplications, inversions, etc. In addition, preimplantation genetic diagnosis (PGD) is another study that allows the genetic analysis of embryos in order to transfer only those healthy embryos with the greatest potential for implantation in the woman's uterus.
As an alternative when the cause of infertility has not been found or when no assisted reproduction treatment has worked, it is possible to use gametes (eggs and sperm) from donors.
Another option available for cases of unexplained infertility is the ERA test in order to transfer the embryos at the time when the endometrium is most receptive to them.
