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…

STUDY QUESTION: Does the use of virtual reality (VR) reduce pain levels experienced by women during transvaginal oocyte retrieval using paracervical block and conscious sedation? SUMMARY ANSWER: The use of VR did not reduce pain levels dur…

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…

Chronic endometritis (CE) is an important factor leading to decreased endometrial receptivity, infertility, and repeated pregnancy loss; endometrial immune dysfunction, abnormal microbial flora, inflammatory status, and other factors play i…

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…

OBJECTIVE: To investigate the relationship between serum 25(OH)D and anti-Müllerian hormone (AMH) among infertile females and their predictive impacts on in vitro fertilization and embryo transfer pregnancy outcome. METHODS: Totally 756 in…

PURPOSE: To 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). METHODS: It is a retrospective study in a university-…

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…

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…

INTRODUCTION: Medical treatment is a less invasive alternative to surgical management of missed miscarriage. Studies have shown that pretreatment with mifepristone can increase the complete abortion rate in management of first-trimester mis…

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…

Anti-Müllerian hormone reflects the continuum of the functional ovarian reserve, and as such can predict ovarian response to gonadotropin stimulation and be used to individualize treatment pathways to improve efficacy and safety. However, c…

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…

PURPOSE: This 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. METHODS: We studied 1…

PURPOSE: To validate the use of the ovarian sensitivity index (OSI) as a measure of ovarian response during in-vitro fertilization (IVF) treatment. METHODS: This is a retrospective study carried out in an assisted reproduction unit in a te…

OBJECTIVE: This 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 bi…

PURPOSE: Analysis 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 o…

PURPOSE: To evaluate the role of Anti-mullerian hormone (AMH) in predicting cumulative pregnancy outcome during in-vitro fertilization (IVF) treatment. METHODS: Serum AMH levels on day 6 of ovarian stimulation were taken from 180 women und…
