Summary: This study aimed to investigate the optimal timing of hCG administration to enhance embryo implantation rates. The results showed that hCG administration induced a significant increase in endometrial receptivity and angiogenesis-related gene expression levels within 72 hours, and promoted the stability of embryo attachment in an in vitro model.

Summary: This study investigated the impact of endometrial receptivity array (ERA) before frozen embryo transfer in patients undergoing in vitro fertilization (IVF). The results showed that the use of ERA did not significantly increase the success rate of IVF cycles, such as the live birth rate. The importance of ERA in improving the pregnancy rate is still unclear.

Summary: During a natural cycle, the morphology of the endometrium changes mostly from type C to type B, the endometrial thickness increases, and the volume decreases. The blood supply of the endometrium, the subendometrial 5 mm and the frequency of peristalsis decrease from ovulation day to transplantation day. Compared with the nonpregnancy group, the pregnancy group tended to have more obvious decreases in endometrial volume and blood flow perfusion. However, these endometrial changes do not mean that pregnancy is bound to occur.

Summary: In a study of 2798 cases, a significant correlation was found between TE grading and initial beta-hCG serum levels after single euploid embryo transfer. However, TE grading was not associated with higher odds of biochemical or clinical pregnancy loss.

Summary: This study evaluated the attachment rate of a human embryonic stem cell-derived trophoblastic spheroid onto endometrial epithelial cells to predict the cumulative live birth rate of an in vitro fertilization (IVF) cycle. The results showed that the BAP-EB attachment rate did not significantly differ between women who achieved a cumulative live birth and those who did not, except for women aged ≥35 years. The BAP-EB attachment rate only offered a modest prediction of the cumulative live birth rate in women aged ≥35 years undergoing IVF.

Summary: This brief review examines the investigation of the endometrial cavity before embryo transfer using various techniques, including hysteroscopy, endometrial biopsy, and ultrasound imaging. These investigative tools are currently controversial and require large prospective controlled trials for validation. Retained embryos during embryo transfer do not appear to have a negative impact on pregnancy outcome, and physical activity immediately after embryo transfer has no impact on pregnancy outcome, according to consistent data.

Summary: Premature initiation of progesterone luteal phase support (LPS) 24 hours after hCG trigger did not affect live birth rate in modified natural cycle frozen-thawed embryo transfer. This study provides valuable insights for clinical decisions and patient choices.

Summary: This study aimed to evaluate the predictive value of endometrial blood flow branches on pregnancy outcomes after hormone replacement therapy-frozen embryo transfer (HRT-FET). The results showed that there were differences in endometrial blood flow branches between pregnant and non-pregnant patients, and the endometrial blood flow branches on the day before embryo transfer were found to be an independent factor influencing the chance of clinical pregnancy. These findings suggest that evaluating endometrial branches using power Doppler ultrasound is a simple and effective approach for predicting pregnancy outcomes during the HRT-FET cycle.

Summary: During frozen embryo transfer cycles, there were no significant changes in the phenotype and function of pNK cells, but pregnancy increased the percentage of CD45(+)CD3(-)CD56(+)pNK cells. Additionally, pNK cells from pregnant patients showed lower cytotoxicity towards K562 cells.

Summary: The study did not find a significant improvement in live birth rates with intrauterine administration of HCG before embryo transfer in women undergoing IVF, although a smaller, clinically important difference could not be ruled out. Treatment outcomes in the control group were lower than expected.

Summary: Pre-eclampsia is a hypertensive disease of pregnancy with mechanisms centered around abnormal placentation, inadequate spiral-artery remodeling, and deficiency in trophoblast invasion. Extracellular vesicles (EVs) are suggested to play a crucial role in pre-eclampsia, potentially influencing immune responses, inflammation, altered angiogenesis, and endothelial dysfunction.

Summary: The study found that higher levels of endometrial Tregs and lower levels of CD16(+) uNK cells may predict a favorable clinical pregnancy outcome in frozen embryo transfer cycles. This research suggests that phenotypic and proportional analyses of endometrial immune cells could complement existing methods in predicting improved pregnancy rates for patients with implantation failure.

Summary: In utero programming plays a crucial role in maternal-fetal health, with dysregulation of uterine immunity potentially leading to adverse health effects. The immune status during pregnancy determines the health trajectory of offspring, impacting cognitive function and mental health. Factors like Th17 T cells may contribute to ASD-like features, highlighting the importance of understanding and intervening in uterine immune activation for fetal brain development.

Summary: Pathogens, including viruses, bacteria, gut microbiome, and parasites, play a significant role in the emergence of new diseases in humans. Studying their ability to cause diseases is important for drug development and prevention of infection-related disorders. During pregnancy, infections by viruses, bacteria, and parasites can have a major impact on maternal and fetal health, particularly affecting fetal brain development and leading to long-term cognitive impairments.

Summary: Autophagy is a crucial process in maintaining normal pregnancy, but it is impaired in preeclampsia. This study demonstrates that hypoxia-reoxygenation treatment disrupts the autophagic machinery in human trophoblasts, leading to the accumulation of protein aggregates. Similar features were observed in the placenta from early-onset preeclampsia deliveries. Evaluation of key regulators and verification of autophagic ultrastructure are essential for accurately assessing autophagy activity in human trophoblasts and placental tissue from preeclampsia deliveries.

Summary: This review introduces studies related to autophagy in the field of reproductive health and provides tips for interpreting experimental results and understanding autophagy. Autophagy is a fundamental process involved in regulating cellular homeostasis, energy production, protein degradation, and maintenance of organelle function. Accurate evaluation of autophagy activity is difficult in fixed tissues, including human samples.

Summary: Preeclampsia (PE) is a major cause of maternal and fetal mortality worldwide, and may lead to dementia later in life. The etiological drivers of PE are still unknown. Cis P-tau is a potential biomarker and etiological driver in pre-clinical Alzheimer's and after brain injury, and can be targeted by a specific antibody. Research has found significant levels of cis P-tau in the placenta and serum of PE patients, indicating its potential role in the development of the disease. The depletion of cis P-tau by the antibody prevents the disruption of trophoblast invasion and endovascular activity, providing valuable insights for early diagnosis and treatment of PE.
