Study questionDoes the use of virtual reality (VR) reduce pain levels experienced by women during transvaginal oocyte retrieval using paracervical block and conscious sedation?Summary answerThe use of VR did not reduce pain levels during oo…

Background and Objectives: To evaluate the significance of serum CA-125 level on the live birth rate of in vitro fertilization (IVF) in women with endometriosis. Materials and Methods: This retrospective observational study included women w…

Background: eMSC) located in the basalis are responsible for the cyclical regeneration of the endometrium after menstruation. Endometrial cells from the menstruation phase have been proven to secrete a higher amount of IL-6 and further enha…

Abstract 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…

PurposeTo evaluate the effect of basal serum testosterone levels on the ovarian response and the cumulative live birth rate of infertile women undergoing in vitro fertilization (IVF).MethodsIt is a retrospective study in a university-affili…

OBJECTIVE: To evaluate the efficacy and safety of acupuncture in the treatment of endometriosis-associated pain. DESIGN: A multicenter, randomized, single-blind, placebo-controlled trial. INSTITUTIONS: Four tertiary hospitals in Jiangxi a…

BackgroundIn IVF/ICSI treatment, the process of embryo implantation is the success rate-limiting step. Endometrial scratching has been suggested to improve this process, but it is unclear if this procedure increases the chance of implantati…

Current contraceptive methods interfere with folliculogenesis, fertilization, and embryo implantation by physical or hormonal approaches. Although hormonal contraceptive pills are effective in regulating egg formation, they are less effecti…

Human endometrium undergoes cycles of regeneration in women of reproductive age. The endometrial mesenchymal stromal/stem cells (eMSC) contribute to this process. Notch signaling is essential for homeostasis of somatic stem cells. However, …

Abstract Human endometrium undergoes cycles of regeneration in reproductive women. The endometrial mesenchymal stromal/stem cells (eMSC) contribute to this process. Notch signaling is essential for the homeostasis of somatic stem cells. How…

The uterine junctional zone represents the juncture between endometrium and myometrium. The junctional zone is hormonally dependent and displays continuous peristaltic activity throughout the menstrual cycle in the nonpregnant state which i…

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…

OBJECTIVE: To study the effect on endometrial and endometriotic cells after co-culture with macrophages, using clonogenic, invasion and self-renewal assays. MATERIALS AND METHODS: Peripheral blood samples, endometrium and endometriotic tiss…

The human endometrium is a highly dynamic tissue with the ability to cyclically regenerate during the reproductive life. Endometrial mesenchymal stem-like cells (eMSCs) located throughout the endometrium have shown to functionally contribut…

ObjectiveTo determine the live birth and cumulative live birth rates of expected poor ovarian responders according to the Bologna criteria and to compare their outcomes with those of expected normal responders.DesignRetrospective analysis.S…

STUDY QUESTION: Does atosiban (oxytocin/vasopressin V1A receptor antagonist), given around embryo transfer improve the live birth rate of women undergoing IVF treatment? SUMMARY ANSWER: The use of atosiban around embryo transfer did not im…

PurposeThis retrospective cohort study evaluated the cumulative live birth rate in women with polycystic ovary syndrome (PCOS) and isolated polycystic ovaries (PCO) undergoing in-vitro fertilisation (IVF) treatment.MethodsWe studied 104 wom…

PurposeTo validate the use of the ovarian sensitivity index (OSI) as a measure of ovarian response during in-vitro fertilization (IVF) treatment.MethodsThis is a retrospective study carried out in an assisted reproduction unit in a teaching…

BackgroundA large number of infertile couples are choosing Chinese herbal medicine (CHM) as an adjuvant therapy to improve their success when undergoing in vitro fertilization (IVF). There is no systematic review to evaluate the impact of C…

ObjectiveThis retrospective study determined for the first time the role of baseline antral follicle count (AFC) and serum anti-Mullerian hormone (AMH) level in the first in-vitro fertilisation (IVF) cycle in predicting cumulative live birt…

PurposeAnalysis of anti-Müllerian hormone (AMH) is becoming of recognized importance in reproductive medicine, but assays are not standardized. We have evaluated the correlation between the new Gen II ELISA kit (Beckman-Coutler) and the old…
