BMC pregnancy and childbirth

BACKGROUND: The aim of this retrospective cohort study was to assess the impact of day 3(D3) embryo cell number on the clinical pregnancy and neonatal outcomes of day 4(D4) single embryo transfer in fresh cycles. METHODS: The study include…

BACKGROUND: Non-invasive chromosome screening (NICS) and trophectoderm biopsy preimplantation genetic testing for aneuploidy (TE-PGT) were both applied for embryo ploidy detection, However, the cumulative live birth rates (CLBR) of NICS and…

BACKGROUND: Surgery for adnexal mass does occur in pregnant women and therefore the choice of surgery during pregnancy needs to be carefully considered and studied. This study aimed to evaluate the safety and feasibility of Laparo-endoscopi…

RESEARCH QUESTION: Is it possible to predict blastocyst quality, embryo chromosomal ploidy, and clinical pregnancy outcome after single embryo transfer from embryo developmental morphokinetic parameters? DESIGN: The morphokinetic parameter…

BACKGROUND: Pain experienced by women in the perinatal period constitutes a complex and multifaceted phenomenon. The aim of the study was to assess conditions of pain locus of control and pain reduction in post-cesarean section parturients.…

BACKGROUND: Cumulative live birth rate (CLBR) is considered as the most important endpoint for assessing the probability of having a baby in a complete in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) treatment cycle. Many…

BACKGROUND: To identify incidence and underlying risk factors for unsuspected placenta accreta spectrum (PAS) and compare the maternal outcomes between suspected and unsuspected cases in three large academic referral centers. METHODS: A re…

PURPOSE: The study aimed to investigate the potential influence of COVID-19 infection on embryo implantation and early development in women undergoing frozen embryo transfer (FET), with a specific focus on infections occurring at different …

BACKGROUND: Adnexal torsion (AT) is a rare emergency complication during pregnancy. Increasing evidence implies that operative laparoscopy for adnexal torsion performed during pregnancy could be safe and feasible. We procured and evaluated …

BACKGROUND: Vitrification procedures decrease intracytoplasmic lipid content and impair developmental competence. Adding fatty acids (FAs) to the warming solution has been shown to recover the lipid content of the cytoplasm and improve deve…

PURPOSE: This study evaluates the efficacy of intrauterine hCG perfusion for RIF, as defined by ESHRE 2023 guidelines, highlighting hCG as a cost-effective alternative to other immunotherapies, especially suitable for less developed regions…

BACKGROUND: Study objectives included the development of a practical nomogram for predicting live birth following frozen-thawed embryo transfers in ovulatory women. METHODS: Totally, 2884 patients with regular menstrual cycles in our cente…

BACKGROUND: The appropriate use of obstetric blood transfusion is crucial for patients with placenta previa and prenatal anemia. This retrospective study aims to explore the correlation between prenatal anemia and blood transfusion-related …

BACKGROUND: A normal luteal function is an essential factor for maintaining pregnancy; luteal phase deficiency decreases embryo implantation and pregnancy rate and increases the early miscarriage rate. In stimulated in vitro fertilization-e…

BACKGROUND: The treatment for recurrent pregnancy loss (RPL) has been addressed in international guidelines. However, limited studies have investigated the risk factors associated with pregnancy and live birth outcomes in patients with RPL …

BACKGROUND: Plasma microRNAs act as biomarkers for predicting and diagnosing diseases. Reliable non-invasive biomarkers for biochemical pregnancy loss have not been established. We aim to analyze the dynamic microRNA profiles during the per…

BACKGROUND: Endometriosis frequently results in pain and infertility. While conservative surgery offers some relief, it often falls short of ensuring satisfactory pregnancy outcomes. Adjuvant GnRH-a is administered post-surgery to mitigate …

PURPOSE: Since the unexplained in vitro fertilization failure occurs frequently, it is of great importance and clinical value to identify potential underlying predictors. This study aimed to explore whether the percentage of sperm with a sm…

BACKGROUND: The aim of the retrospective cohort study was to investigate the prognostic effect of subchorionic hematomas (SCH) in the first trimester on pregnancy outcomes after euploid embryo transfer. METHODS: We retrospectively analyzed…

BACKGROUND: The objective of this research was to elucidate the association between the length of infertility and the outcomes of intrauterine insemination (IUI) in women of varying ages - a topic that has been the subject of investigation …

OBJECTIVES: To assess the value of intraovarian PRP in women with low ovarian reserve. SEARCH STRATEGY: Screening of databases from inception to January 2023 using the keywords related to "Platelet-rich plasma" AND "poor ovarian reserve" O…

OBJECTIVE: This study aimed to compare the per OPU clinical outcomes for transfer of Day 3 double cleavage-stage embryos (DET) and Day 5 single blastocyst-stage (SBT) in patients with five or fewer good quality embryos on day 3 per occyte p…

BACKGROUND: Postpartum haemorrhage (PPH) continues to stand as the primary cause of maternal morbidity and mortality post-delivery, with twin pregnancies carrying a heightened risk of PPH compared to singleton deliveries. OBJECTIVES: To in…

BACKGROUND: Laser-assisted hatching (LAH) stands as the predominant technique for removing the zona pellucida (ZP) in embryos, primarily consisting of two methods: drilling laser-assisted hatching (D-LAH) and thinning laser-assisted hatchin…

BACKGROUND: Pregnancy begins with a fertilized ovum that normally attaches to the uterine endometrium. However, an ectopic pregnancy can occur when a fertilized egg implants and grows outside the uterine cavity. Tubal ectopic pregnancy is t…
