ObjectiveThis study aimed to explore the correlation between ambient particulate matter 2.5 (PM2.5) concentration and sperm quality among northern Thai men exposed to the seasonal air pollution from the agricultural burning process.MethodsT…

OBJECTIVE: To compare the ovarian reserve of women of reproductive age with and without thyroid autoimmunity (TAI). METHODS: We performed a retrospective analysis of medical records from an assisted reproduction clinic from February 2017 t…

OBJECTIVE: Today, researchers have succeeded in achieving oocyte-like cells through the in vitro differentiation of stem cells. MicroRNAs are key regulators of oocyte development. In this study we decided to evaluate the expression pattern …

OBJECTIVE: Premature ovary failure (POF) is a severe health condition with multiple negative outcomes, which deteriorate a patient's life. The current study aimed to evaluate the therapeutic effect of mesenchymal stem cells (MSCs) derived f…

OBJECTIVE: Women undergoing IVF who have had a previous c-section (CS) have a lower live birth rate than those with a previous vaginal delivery. However, the precise underlying mechanisms need clarification. Does a previous CS affect the pa…

OBJECTIVE: The study aimed to evaluate the impact of CE on the expression of HOXA10 and HOXA11 during the late proliferative phase in the endometrium of infertile women. METHODS: A prospective, translational cohort study was conducted in p…

OBJECTIVE: The objective of this research is to investigate the association between the concentrations of soluble human leukocyte G antigen (sHLA-G) in the follicular fluid (FF) in infertile patients with peritoneal endometriosis submitted …

OBJECTIVE: To use hashtag and content analysis to determine the prevalence, authorship, and types of fertility-related and oncofertility information shared on Instagram in Brazil. METHODS: Eleven fertility-related hashtags were chosen acco…

OBJECTIVE: To evaluate if it possible to improve ovarian reserve parameters and oocyte retrieval in poor responders who undergo intraovarian injection of platelet-rich plasma (PRP). METHODS: Prospective cohort study. We included 148 poor r…

OBJECTIVE: To evaluate the impact of possible maternal and paternal prognostic factors and ovarian stimulation protocols on clinical pregnancy and live birth rates in intrauterine insemination (IUI) cycles. METHODS: Retrospective observati…

The development of endometrial receptivity is crucial for successful embryo implantation and the initiation of pregnancy. Understanding the molecular regulatory processes that transform the endometrium into a receptive phase is essential fo…

OBJECTIVE: To evaluate factors involved in spontaneous pregnancy rate after surgery for endometriosis in patients with endometriosis and infertility. METHODS: This retrospective study spanned from 2014 to 2020 and included a follow-up peri…

OBJECTIVE: Previous studies have shown that the meiotic spindle is not always aligned with the first polar body (PB) in metaphase II human oocytes. Polarized Light Microscopy (PLM) has been used to observe and locate the meiotic spindle to …

OBJECTIVE: Many pieces of literature have reported that inherited and acquired thrombophilia might be a risk factor for recurrent implantation failure (RIF), however, most studies have only focused on RIF patients and not their male partner…

OBJECTIVE: To evaluate the impact of prior use of combined oral contraceptives in assisted reproduction techniques with ovulation blockade by oral progestin. METHODS: Retrospective cohort study with a single-center convenience sample of pa…

OBJECTIVE: Adenomyosis associated with subfertility is a situation of a dilemma for the treating clinician as the treatment is highly controversial and there remains an overall lack of consensus regarding the value of conservative surgery w…

OBJECTIVE: To evaluate the efficacy of sublingually administered human chorionic gonadotropin (HCG) in combination with clomiphene citrate (CC) or letrozole (LTZ) for ovulation induction. METHODS: In this prospective, double-blind, randomi…

This systematic review and meta-analysis of randomized controlled trials aimed to evaluate the effect of a single-dose gonadotropin-releasing hormone agonist administration in the frozen-thawed embryo transfer cycle on pregnancy outcomes. A…

OBJECTIVE: The safety of assisted reproductive technology can be assessed by examining birth weight as an outcome measure. The objective of this study was to evaluate the effect of endometrial thickness during embryo transfer on newborn bir…

OBJECTIVE: Human reproduction presents a challenge for our species, as evidenced by the escalating rates of infertility. This trend has prompted inquiries into diverse strategies aimed at mitigating infertility and enhancing conception rate…

Despite the widespread use of transvaginal ultrasound-guided oocyte retrieval in assisted reproductive technology procedures, there is a lack of systematic data on the incidence and nature of its complications. This makes it difficult for h…

OBJECTIVE: Vitamin D (VD) is a fat-soluble steroid hormone, synthesized by the skin, most known for its role in bone mineral balance. Vitamin D receptors (VDR) are also found in the female reproductive system, but their role remains unclear…

A 29-year-old female who received assisted reproductive therapy (IVF) in our infertility clinic, at gestational age of 7w + 2d following embryo transfer, presented with a favorable rise of β-hCG level with no detectable gestational sac in t…
