Résumé
During the last decade, there has been growing evidence for the involvement of prokineticins and their receptors (PROK/PROKR) in human reproduction, with multiple roles in the female and male reproductive systems. The PROK/PROKR signalling complex has been reported as a new actor in ovary, uterus, placenta, and testis physiology, with marked dysfunction in various pathological conditions such as polycystic ovary syndrome, recurrent pregnancy loss, preeclampsia, and ectopic pregnancy. Altogether, the results strongly suggest the involvement of prokineticins in spermatogenesis, oocyte competence, embryo implantation, pregnancy, and delivery, and argue for the clinical relevance of these cytokines and their receptors as diagnostic markers for several reproductive diseases.
