’-omics’ technology and human reproduction: reproductomics

The success of assisted reproduction technology is highly dependent on a precise selection of gametes and embryos and determining the best endometrial window for embryo implantation. For many years, morphological criteria have constituted the only way to assess spermatozoon, oocytes, embryos and endometrial samples in order to improve outcomes. However, this approach has reached a ceiling of success and has been related to unacceptably high rates of multiple pregnancies. New technologies have been developed in order to improve the results and reduce risks via better selection of those gametes and embryos with the highest pregnancy potential, and of more favorable endometrial environments fo…
