Several studies have explored the relationship among traditional semen parameters, sperm DNA fragmentation (SDF), and unexplained recurrent miscarriage (RM); however, the findings remain controversial. Hence, we conducted a meta-analysis to explore the relationship among traditional semen parameters, SDF, and unexplained RM. Multiple databases, including PubMed, Google Scholar, MEDLINE, Embase, Cochrane Library, Web of Science, and China National Knowledge Infrastructure (CNKI), were searched to identify relevant publications. From the eligible publications, data were extracted independently by two researchers. A total of 280 publications were identified using the search strategy. According to the inclusion/exclusion criteria, 19 publications were eligible. A total of 1182 couples with unexplained RM and 1231 couples without RM were included in this meta-analysis to assess the relationship among traditional semen parameters, SDF, and unexplained RM. Our results showed that couples with unexplained RM had significantly increased levels of SDF and significantly decreased levels of total motility and progressive motility compared with couples without RM, although significant differences were not observed in the semen volume, sperm concentration, and total sperm count between couples with and without RM. The SDF assay may be considered for inclusion in evaluations of couples with unexplained RM.

The purpose of this publication is to summarize the current data on the effectiveness of progestogens in patients with threatened miscarriage (vaginal bleeding in the first trimester of pregnancy) and to review the updated UK National Institute for Health and Care Excel (NICE) clinical guidelines on ectopic pregnancy and miscarriage.In accordance with the opinion of the Cochrane Society experts and the updated NICE clinical guidelines for 2021, vaginal progesterone at a dose of 800 mg/day is the only intervention that has been shown to be effective in increasing live births compared to placebo for women with one or more previous miscarriages and early vaginal bleeding (relative risk 1.08, 95% confidence interval 1.02–1.15, high certainty evidence). Upon confirmation of fetal heartbeat, this treatment should be extended until 16 weeks of gestation.There is still uncertainty over the effectiveness and safety of alternative progestogen treatments (as dydrogesterone) for threatened and recurrent miscarriage. There is also no evidence of benefit of any other preparations or doses of progesterone in patients at risk of miscarriage.

Abstract Background: Recurrent pregnancy loss (RPL) is described as two or more spontaneous abortions. Until now, although various factors such as genetic, endocrinology, anatomy, immunology, and microbiology have been distinguished that affect abortions, the precise basic etiology in up to 50% of RPL cases are not determined. Human cytomegalovirus (CMV) infection and host genetic background, like IL-6 SNP polymorphisms play important roles in RPL etiology. Objective: This study aimed to evaluate relationship among single nucleotide polymorphisms (-634C/G and -174 G/C) in the IL-6 gene with CMV infection and risk of RPL for early detection and treatment of RPL. Materials and methods: This case-control study was carried on 80 Iranian females with RPL and 80 healthy females as control group. The extraction of DNA from samples and detection of CMV and IL6 SNPs were determined by Tetra ARMS-PCR. Finally, the statistical analysis for detection CMV and two polymorphisms roles in RPL were analyzed by Epi Info TM software by X2 test. Results: Our results indicated an increased rate of CMV infection in RPL group (44%) versus the control group (25.45%). Also, the prevalence of IL-6 -634C/G genotype among RPL patients with CMV infection was 80%, while the frequency of this genotype among RPL patients without CMV infection was 50%. Furthermore, no substantial relation was found between IL-6 -174 G/C genotypes and RPL (P ≤0.0001). BesidesConclusion: This study not only indicated a significant role of CMV in RPL, but also showed CMV association with allele G in IL6 -634 among Iranian women. In addition, suggested the use of CMV and IL-6 -634 GG genotypes in RPL as diagnostic and prognostic biomarkers in Iranian population.

Background: Repeated miscarriage can cause tissue injury can lead to the formation of antibodies to the phospholipids. Recurrent miscarriage (RM) is considering the one of the most common cause of sterility. Which has received more attention in recent years as a result of an increase in the number of reproductive-aged women. Materials and Methods: Plasma samples were tested for antiphospholipid antibodies using ELISA, and platelet count using Sysmex (KX21) Heamatology analyzer and Activated Partial Thromboplastin Time using semi-automated machine (STAGO PT31039352 (for coagulation). Results: The prevalence of Anti phospholipid antibodies (APL) was 30.5% in Sudanese patients with recurrent miscarriage, the prevalence of (Anti phospholipid Antibodies-IgM and IgG) was found to be 23.6% in patients with recurrent miscarriage compared to (Anti phospholipid Antibodies-IgG) was found to be 11.1% ((P value≤0.001), low platelets count (<50×109/l) observed in 10 (13.5%), as well as prolongation of activated partial thromboplastin time (APTT) among studied group were detected among 19 (26.1%). Conclusion: Higher prevalence of antiphospolidids antibodies, and acquired thrombophilia was detected among Sudanese women with recurrent abortion; The findings are concerning because they link an increased risk of thrombosis and a hypercoagulable state lead to recurrent miscarriage in pregnant women.
