BMC pregnancy and childbirth

BACKGROUND: Angiomyofibroblastoma (AMFB) is a relatively rare benign mesenchymal tumor predominantly observed in premenopausal women. We present a case of vulvar AMFB in a 29-year-old woman, with the tumor measuring approximately 6 cm in di…

BackgroundChoriocarcinoma coexisting with intrauterine pregnancy is extremely rare and necessitates early diagnosis.Case presentationA primigravida at 27+ weeks of gestation presented with a 3-day history of worsening abdominal pain. An ult…

BACKGROUND: This retrospective study aimed to evaluate the association between endometrial thickness (EMT) on the day of human chorionic gonadotropin (hCG) trigger and the cumulative live birth rate (CLBR) across one oocyte-retrieval cycle.…

OBJECTIVE: Glucose-6-phosphate dehydrogenase (G6PD) deficiency is primarily characterized by neonatal jaundice and acute/chronic hemolytic anemia. This study aimed to examine the influence of different G6PD genotypes on pregnancy and neonat…

BACKGROUND: Preterm birth (PTB), which is defined as delivery before 37 weeks of gestation, is the leading cause of neonatal morbidity, long-term developmental impairment, and infant mortality. In South Korea, PTB has become a critical conc…

BackgroundChronic endometritis (CE) has been associated with implantation failure and recurrent reproductive failure. Antibiotic therapy is widely used as a first-line treatment for CE, and previous studies have suggested that successful tr…

BackgroundPolycystic ovary syndrome (PCOS) is frequently accompanied by insulin resistance (IR) and abnormal glucose metabolism, impairing fertility and pregnancy outcomes. This retrospective study aimed to investigate their associations wi…

BACKGROUND: The aim of the study is to compare the risks and benefits of bladder flap creation and omission during cesarean delivery. METHODS: The databases search from inception to August 2025 included PubMed, Scopus, Embase, Web Of Scienc…

BACKGROUND: The differences between adenomyosis subtypes in clinical features and reproductive outcomes remain largely unexplored. This study aimed to compare clinical features and reproductive outcomes after the first frozen embryo transfe…

ObjectiveTo evaluate and compare the efficacy of tubal reanastomosis and in vitro fertilisation in achieving reproductive success in women who had undergone tubal ligation and desired additional children.MethodsThis study included 152 and 9…

BackgroundLow birth weight (LBW) significantly influences neonatal prognosis as well as growth and development in adult. This study aimed to explore the increased risk of low birth weight (LBW) in singleton live births in connection with in…

BACKGROUND: Assisted reproductive techniques (ART) are an effective solution for infertility treatment. Miscarriage is a common and distressing complication, the incidence of which is much higher in couples undergoing ART than in natural pr…

BackgroundThe follicular-phase long GnRHa protocol is a common protocol in COH. This study mainly analyzed the recovery of FSH levels on the day of Gn initiation compared with basal FSH levels on the day of downregulation and studied the co…

BackgroundAssisted reproductive technologies (ART) have been proven to be associated with the increased risk of pregnancy complications such as gestational hypertension and neonatal disorders, which may have negative effects on offspring's …

BACKGROUND: This study evaluated the effects of different ovulation trigger strategies on pregnancy outcomes in letrozole-stimulated and modified natural frozen–thawed embryo transfer (L-FET and mNC-FET) cycles. METHODS: A total of 2053 eli…

BACKGROUND: Spontaneous preterm labor (SPL) is a significant obstetric concern, and recent literature suggests an association with adenomyosis. In this study, we compared adenomyosis and endomyometrial junctional zone (JZ) in women with and…

BACKGROUND: Euploid miscarriage may indicate underlying non-genetic factors in the couples. This study aimed to investigate the subsequent live birth rates in women with a prior euploid or aneuploid sporadic miscarriage (SM) in assisted rep…

BackgroundProgestin-primed ovarian stimulation (PPOS) has emerged as an alternative to GnRH-antagonist protocols in IVF, yet its impact on embryo chromosomal competence remains controversial. Evidence is particularly limited regarding wheth…

ObjectiveTo estimate the risk of cesarean scar diverticulum associated with the timing of cesarean section.Patients and methodsThis was a retrospective cohort study involving three Chinese hospitals. A total of 11,132 women were included in…

RESEARCH QUESTION: Is there a difference in the euploidy status and pregnancy outcomes among patients undergoing preimplantation genetic testing for aneuploidy (PGT-A) inoculated with inactivated severe acute respiratory syndrome coronaviru…

BACKGROUND: The role of serum progesterone levels and the benefit of rescue luteal support in frozen embryo transfer (FET) cycles remain debated. While low serum progesterone has been linked to poorer outcomes, evidence on whether supplemen…

BACKGROUND: Hereditary Hemorrhagic Telangiectasia (HHT) is a rare vascular disorder with mucocutaneous telangiectasia. Hormones are hypothesized to play a role in reducing bleeding in these patients; however, clear evidence is currently lac…

BACKGROUND: Serum beta-human chorionic gonadotropin (β-hCG) hormone is a well-established biomarker used for pregnancy monitoring and prognosis in in vitro fertilization (IVF) cycles. After embryo transfer, a high serum β-hCG level with a p…

OBJECTIVE: To investigate the relationship between third-trimester antenatal depression (AND) and the number of pregnancies, considering the possible moderating role of dysmenorrhea. METHODS: A total of 1,178 pregnant women in their third t…

BACKGROUND: We aimed to evaluate the risk of perinatal complications in subsequent pregnancies after different types of myomectomy, viz. open, laparoscopic, or hysteroscopic. Moreover, we investigated whether the time interval from myomecto…
