Adult endometrial glands undergo cyclic regeneration and development during the menstrual cycle. Their secretions are vital for endometrial functions and early pregnancy, yet the mechanisms controlling gland development are not well underst…

OBJECTIVE: To determine the future priorities for ectopic pregnancy research. DESIGN: Potential research questions were collated from an initial international survey, a systematic review of clinical practice guidelines, and Cochrane system…

PURPOSE: To assess the association of serum vitamin D level and the live birth rate in women undergoing frozen embryo transfer (FET). METHODS: This is a retrospective cohort study involving 1489 infertile women who had frozen embryo transf…

BACKGROUND: Progestins can block endogenous luteinizing hormone secretion from the pituitary gland and have shown similar efficacy in terms of collecting competent oocytes and embryos; however, some inconsistencies have been proposed by the…

BACKGROUND: In the human endometrium, studies show the importance of extracellular vesicles in mediating various physiological as well as pathological processes. We have demonstrated that the myometrial cells are candidate niche cells of th…

BACKGROUND: The human endometrium is a regenerative tissue relying on stem/progenitor cells. Endometrial mesenchymal stem cells (eMSCs) are typically enriched using perivascular markers like CD140b and CD146. However, the identity of more p…

BACKGROUND: The monthly regeneration of human endometrial tissue is maintained by the presence of human endometrial mesenchymal stromal/stem cells (eMSC), a cell population co-expressing the perivascular markers CD140b and CD146. Endometria…

BACKGROUND: At menstruation, the functional layer of the human endometrium sheds off due to the trigger of the release of inflammatory factors, including interleukin 6 (IL-6), as a result of a sharp decline in progesterone levels, leading t…

Severe endometrium damage causes pathological conditions such as thin endometrium and intrauterine adhesion, resulting in uterine factor infertility. Mesenchymal stem cell (MSC) therapy is a promising strategy in endometrial repair; yet, ex…

PURPOSE: To evaluate the impact of embryo banking on the cumulative live birth rate (CLBR) and the time to live birth (TTLB) in poor ovarian responders (POR) according to the Bologna criteria. METHODS: A total of 276 infertile women underg…

OBJECTIVE: Vitamin D receptors are present in the female reproductive tract. Studies on the association between serum vitamin D level and pregnancy rate of in vitro fertilization (IVF) showed inconsistent results and focused on a single fre…

During implantation, a symphony of interaction between the trophoblast originated from the trophectoderm of the implanting blastocyst and the endometrium leads to a successful pregnancy. Defective interaction between the trophoblast and end…

BACKGROUND: In vitro fertilization (IVF) is a well-established method to treat various causes of infertility. Some previous retrospective studies suggested a lower ovarian response in Asian women compared to Caucasian women. However, the ov…

STUDY QUESTION: Can the priorities for future research in infertility be identified? SUMMARY ANSWER: The top 10 research priorities for the four areas of male infertility, female and unexplained infertility, medically assisted reproduction…

STUDY QUESTION: Can a core outcome set to standardize outcome selection, collection and reporting across future infertility research be developed? SUMMARY ANSWER: A minimum data set, known as a core outcome set, has been developed for rand…

STUDY QUESTION: Can consensus definitions for the core outcome set for infertility be identified in order to recommend a standardized approach to reporting? SUMMARY ANSWER: Consensus definitions for individual core outcomes, contextual sta…

STUDY QUESTION: Can the priorities for future research in infertility be identified? SUMMARY ANSWER: The top 10 research priorities for the four areas of male infertility, female and unexplained infertility, medically assisted reproduction…

BACKGROUND: The identification of endometrial stem/progenitor cells in a high turnover rate tissue suggests that a well-orchestrated underlying network controls the behaviour of these stem cells. The thickness of the endometrium can grow fr…

STUDY QUESTIONS: We aim to produce, disseminate and implement a core outcome set for future infertility research. WHAT IS KNOWN ALREADY: Randomized controlled trials (RCTs) evaluating infertility treatments have reported many different out…
