- Previous transcriptome studies of the human endometrium have revealed hundreds of simultaneously up- and down-regulated genes that are involved in endometrial receptivity. However, the overlap between the studies is relatively small, and we are still searching for potential diagnostic biomarkers. Here we perform a meta-analysis of endometrial-receptivity associated genes on 164 endometrial samples (76 from ‘pre-receptive’ and 88 from mid-secretory, ‘receptive’ phase endometria) using a robust rank aggregation (RRA) method, followed by enrichment analysis, and regulatory microRNA prediction. We identify a meta-signature of endometrial receptivity involving 57 mRNA genes as putative receptivity markers, where 39 of these we confirm experimentally using RNA-sequencing method in two separate datasets. The meta-signature genes highlight the importance of immune responses, the complement cascade pathway and the involvement of exosomes in mid-secretory endometrial functions. Bioinformatic prediction identifies 348 microRNAs that could regulate 30 endometrial-receptivity associated genes, and we confirm experimentally the decreased expression of 19 microRNAs with 11 corresponding up-regulated meta-signature genes in our validation experiments. The 57 identified meta-signature genes and involved pathways, together with their regulatory microRNAs could serve as promising and sought-after biomarkers of endometrial receptivity, fertility and infertility.

- Introduction: The objective of this study was to compare ever-in life contraception use, use of contraception at current conception, and planned use of contraception after an induced abortion, among three groups of women: migrants, second-generation migrants and non-migrant women, and to compare the types of contraception methods used and intended for future use among the three groups of women. Methods: The cross-sectional study administered a questionnaire face-to-face to women aged 18 years and older who were seeking abortion care at one of six abortion clinics in Stockholm County from January to April 2015. Results: The analysis included 637 women. Migrants and second-generation migrants were less likely to have used contraception historically, at the time of the current conception, and to plan to use contraception after their induced abortion compared with non-migrant women. Historically, non-migrants had used pills (89%) and withdrawal (24%) while migrants had used the copper intrauterine device (24%) to a higher extent compared to the other two groups of women. Both the migrants (65%) and second-generation migrants (61%) were more likely than the non-migrants (48%) to be planning to use long-acting reversible contraception. Conclusions: Lower proportions of contraception use were found in migrants and second-generation migrants than in non-migrants. In addition, there were significant differences in the types of contraception methods used historically and intended for future use.
