Reproductive Challenges of the Ageing Female: A Comprehensive Narrative Review

BJOG: An International Journal of Obstetrics &Gynaecology, EarlyView.
ABSTRACT Changes in societal norms over the last few decades have resulted in novel family planning trends, notably delayed childbearing and increased maternal age at the birth of the first child. Despite advances in reproductive medicine, ageing poses significant challenges.

Peritoneal Fluid‐Derived Small Extracellular Vesicle Proteins as Potential Biomarkers for Endometriosis: A Case–Control Study

BJOG: An International Journal of Obstetrics &Gynaecology, EarlyView.
ABSTRACT Objective To demonstrate the presence of peritoneal fluid (PF)‐derived small extracellular vesicles (sEVs) in endometriosis and control samples, to characterise their protein content and to define endometriosis‐specific biomarkers within the sEV proteome. Design Case–control experimental study. Setting Academic endometriosis centre.

#167 : Role of Endometrial Receptivity Using 3D Doppler Ultrasound on Pregnancy Outcome of IVF-FET Cycles

Fertility & Reproduction, 2023
Background: The success of in vitro fertilization and embryo transfer (IVF-ET) cycles depends primarily on the quality of the embryo and the receptivity of the uterus.

Incretin‐Based Medications in Women and Reproduction: A Systematic Scoping Review and Consensus Guidelines for Clinical Practice

Obesity Reviews, EarlyView.
ABSTRACT Introduction Pregnancy concurrent with incretin‐based medications is contraindicated due to unknown risk of teratogenicity, as is breastfeeding. The aim of this systematic scoping review was to investigate potential risks and benefits of incretin‐based medications in relation to preconception, pregnancy, and postnatal health, and to propose ...

Spatially Organized Human Ovarian Spheroids Instruct Endometrial Morphogenesis

Advanced Science, Volume 13, Issue 55, 5 October 2026.
A spatially organized human follicle‐like spheroid (SPHEGaT) composed of granulosa cells (GCs) and stromal‐derived theca‐like cells (TLCs) establishes sustained steroidogenesis in vitro. When co‐cultured with human endometrial organoids (EMOs), estradiol (E2) and progesterone (P4) exchange induces secretory/progesterone‐responsive differentiation ...

Weighted Single‐Step GWAS Reveals Genetic Mechanisms Underlying Pregnancy Loss in Early Nellore Heifers

Animal Genetics, Volume 57, Issue 5, October 2026.
ABSTRACT Pregnancy loss (PL) affects reproductive efficiency in beef cattle, yet its genetic architecture remains poorly understood in Bos indicus populations. Here, PL was defined as failure from pregnancy diagnosis to calving, capturing a window approximately 60 days after the breeding season.

Melatonin improves endometrial receptivity and embryo implantation via MT2/PI3K/LIF signaling pathway in sows

Journal of Animal Science and Biotechnology
Background Increased backfat thickness of sows in early gestation is negative to reproductive performance. Endometrial receptivity is an important determinant of reproductive success, but it is unclear whether the effect of sow backfat thickness on ...

Oocyte–cumulus cell interaction: a key factor in early embryo development

Biological Reviews, Volume 101, Issue 5, Page 2265-2278, October 2026.
ABSTRACT The evaluation of oocyte competence is a fundamental step in achieving successful outcomes following assisted reproduction techniques (ART). At present, however, conventional oocyte maturation assessment is carried out by morphological observation, which is a subjective method that does not consider molecular features.

Determining a Treatment Regimen With Optimal Pregnancy Outcomes in Patients With Chronic Endometritis: A Systematic Review and Network Meta‐Analysis

Health Science Reports, Volume 9, Issue 10, October 2026.
ABSTRACT Background and Aims Chronic endometritis (CE) negatively impacts pregnancy outcomes. This study aimed to compare the efficacy of various treatment regimens on pregnancy outcomes in women with CE. Methods We performed a systematic review followed by an NMA in accordance with the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses
