ReviewZika virus and reproduction: facts, questions and current management.
Zika virus (ZIKV) is an arthropod-borne virus of the family Flaviviridae, genus Flavivirus. ZIKV is currently the focus of an ongoing pandemic and worldwide public health emergency. Although originally isolated in 1947, its pathogenesis was poorly known and very few documented infections were published until recently. Its route of transmission and its impact on reproduction and pregnancy have only recently begun to be disclosed. ⋯ These new and relevant findings have led many countries and institutions to release updated and regular guidance for preconception counselling and ART to prevent the sexual transmission of ZIKV. Progress in understanding the sexual transmission of ZIKV and its dissemination to genital systems would also help to better anticipate and control outbreaks of potentially sexually transmissible infectious agents.

ReviewMetabolomics as a tool to identify biomarkers to predict and improve outcomes in reproductive medicine: a systematic review.
Infertility is a complex disorder with significant medical, psychological and financial consequences for patients. With live-birth rates per cycle below 30% and a drive from the Human Fertilisation and Embryology Authority (HFEA) to encourage single embryo transfer, there is significant research in different areas aiming to improve success rates of fertility treatments. One such area is investigating the causes of infertility at a molecular level, and metabolomics techniques provide a platform for studying relevant biofluids in the reproductive tract. ⋯ A range of sophisticated modern metabolomic techniques are now more widely available and have been applied to the analysis of the female reproductive tract. However, this review has revealed the paucity of metabolomic studies in the field of fertility and the inconsistencies of findings between different studies, as well as a lack of research examining the metabolic effects of various gynecological diseases. By incorporating metabolomic technology into an increased number of well designed studies, a much greater understanding of infertility at a molecular level could be achieved. However, there is currently no evidence for the use of metabolomics in clinical practice to improve fertility outcomes.
