The use of oocyte donation (OD) has increased continuously over the last three decades, and it is now an indispensable part of assisted reproductive technology (ART). With OD, it has become possible to overcome the biological barrier of ovarian follicle pool depletion and the general age-related decline in fertility. This review contains a thorough appraisal of the safety of OD with an analysis of short-term pregnancy outcomes. Salient up-to-date evidence was evaluated, which revealed that in comparison with both IVF with autologous oocytes, and naturally conceived pregnancies, there is: (i) an increased risk of hypertensive disorders of pregnancy and preeclampsia; (ii) an increased risk of low birth weight and preterm birth and (iii) an increased risks of obstetric emergencies, following OD treatment. As a precaution, it is therefore highly encouraged to perform only single embryo transfer (SET) and to prescribe prophylactic low-dose aspirin during OD pregnancies.

Gestational diabetes mellitus (GDM) is a common complication during pregnancy. This retrospective study investigates the correlation between umbilical blood flow index and maternal-fetal outcomes in pregnant women with GDM, aiming to contribute to evidence-based risk assessment and management strategy in this high-risk obstetric population. This retrospective study recruited 119 pregnant women with GDM who were admitted to the Yichang Central People's Hospital, between January 2022 and January 2024.

Intrahepatic cholestasis of pregnancy (ICP) is associated with adverse perinatal outcomes, yet the correlation between ICP and the neutrophil-to-lymphocyte ratio (NLR) remains unclear. This study aims to investigate the diagnostic value of NLR in ICP. In this retrospective case-control study, 113 patients with ICP treated in Beilun District People's Hospital from January 2020 to December 2022 were recruited and categorized as the ICP group, and 209 healthy pregnant women treated during the same period were selected as the control group.

Maternal nutrition during pregnancy plays a pivotal role in influencing both maternal and fetal health, impacting neonatal anthropometric outcomes and long-term disease susceptibility. An advanced maternal age (AMA ≥ 35 years) has been linked to increased risks of obstetric complications and adverse neonatal outcomes, yet its specific nutritional profile remains underexplored. : This study aimed to evaluate the nutrient and polyphenol intakes of women at an AMA compared to those of a younger control group and to investigate associations with neonatal anthropometric measures.
