VAD due to NPL 2nd stage results in adverse perinatal outcome in the index and subsequent pregnancies. VAD due to NPL 2nd stage in the index pregnancy is an independent risk factor for NPL 1st stage and NPL 2nd stage during the subsequent pregnancy.
Although sperm DNA fragmentation (SDF) is correlated with infertility, recurrent pregnancy loss (RPL), and childhood morbidity, the utility of SDF assays as part of the patient's evaluation has been debated. Proponents of this measure suggest that SDF assays can guide the management of infertile couples with repeated IVF failure, couples with unexplained infertility, infertile couples with high SDF risk factors, infertile men with varicocele, and couples with RPL. On the other hand, critics question the added value of SDF indices. The cost and controversy of SDF assays have resulted in its low utilization. The aim of the current review is to determine which patient populations would most benefit from SDF assays and how SDF can guide the management of infertility.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
