Mmu-miR-126a-3p plays a role in murine embryo implantation by regulating Itga11.
miR-126a-3p has been found to be specifically up-regulated in the process of murine embryo implantation. This study aimed to further clarify the role of miR-126a-3p in embryo implantation. The expression of miR-126a-3p in implantation sites was significantly higher than that in interimplantation sites (P = 0.009). ⋯ Loss of function of miR-126a-3p significantly reduced the number of implantation sites in vivo (P = 0.013). Collectively, miR-126a-3p may play a major role in embryo implantation by regulating Itga11, possibly through impairing cell migratory and invasive capacity. These findings should contribute to a better understanding of the miRNA-based mechanism of embryo implantation.

Review Meta AnalysisDoes ovarian stimulation for IVF increase gynaecological cancer risk? A systematic review and meta-analysis.
The aim of this study was to evaluate whether ovarian stimulation for IVF increases the risk of gynaecological cancer, including ovarian, endometrial, cervical and breast cancers, as an independent risk factor. A systematic review and meta-analysis was conducted. Clinical trials that examined the association between ovarian stimulation for IVF and gynaecologic cancers were included. ⋯ Among these studies, 175 ovarian, 48 endometrial, 502 cervical and 866 cases of breast cancer were reported. The meta-analysis found no significant association between ovarian stimulation for IVF and increased ovarian, endometrial, cervical and breast cancer risk (odds ratio [OR] 1.06, 95% confidence interval [CI] 0.85 to 1.32; OR 0.97, 95% CI 0.58 to 1.63; OR 0.43, 95% CI 0.30 to 0.60; OR 0.69, 95% CI 0.63 to 0.76, respectively). Ovarian stimulation for IVF, therefore, does not increase the gynaecologic cancer risk, whether hormone-dependent endometrial and breast cancer or non-hormone-dependent ovarian and cervical cancer.

ReviewThe Alpha Consensus Meeting on the professional status of the clinical embryologist: proceedings of an expert meeting.
This proceedings report presents the outcomes from an international Workshop designed to establish consensus on the professional status of the Clinical Embryologist, and then to work towards creating international standards that can be referenced by regulators and professional societies around the world. The participants represented a total of 20 countries (Australia, Austria, Belgium, Brazil, Canada, China, Croatia, Finland, France, Germany, Ireland, Italy, the Netherlands, Russia, South Africa, Spain, Sweden, Turkey, UK and USA) and 18 national and regional societies (as presented in the list of participants). This report includes general presentations about current practice, and factors for consideration in the development of a competency-based framework for certification of Clinical Embryologists.

Case ReportsThe effects of liraglutide on male fertility: a case report.
Liraglutide is an agonist of the glucagon-like peptide I receptor, and is commonly recommended as a treatment for obesity and type 2 diabetes mellitus. Adverse effects related to liraglutide include acute pancreatitis and polyarthritis. No studies, however, have reported an adverse effect of liraglutide on male reproduction. This case report shows a deleterious effect of liraglutide on male reproductive function.
