A Decline in Follicle Cell Function Is a Major Driver of Drosophila Ovarian Aging

Aging Cell, Volume 25, Issue 5, May 2026.
Aging drives a progressive accumulation of defects in somatic follicle cells of the Drosophila ovary. These defects are accompanied by reduced tissue and genome integrity, altered transcriptional profiles, and disrupted germ‐soma coordination. Targeted overexpression of Atg8a in a subset of follicle cells mitigates these defects and preserves ...

An egg production method for estimating spawning biomass of pelagic fish: Application to the northern anchovy, Engraulis mordax [PDF]

, 1985
Fishery scientists engaged in estimating the size of free-swimming populations have never had a technique available to them whereby all the parameters could be estimated from a resource survey and where no parameter values need to be assumed. Recognizing

Luteinizing hormone receptor knockout mouse: What has it taught us?

Andrology, Volume 14, Issue 4, Page 1017-1028, May 2026.
Abstract Luteinizing hormone (LH), along with its agonist choriongonadotropin (hCG) in humans, is the key hormone responsible for the tropic regulation of the gonadal function. LH and hCG act through their cognate receptor, the luteinizing hormone/choriongonadotropin receptor (LHCGR; more appropriately LHR in rodents lacking CG), located in the testis ...

Mutation in MSH5 Causes Primary Ovarian Insufficiency and Successful Therapeutic Intervention by In Vitro Fertilisation

Journal of Cellular and Molecular Medicine, Volume 30, Issue 9, May 2026.
ABSTRACT Primary ovarian insufficiency (POI) is a genetically heterogeneous disorder characterised by cessation of menstruation before the age of 40 years with elevated levels of follicle‐stimulating hormone. Germline variants in the MSH5 gene cause POI. In this study, we investigated a Han Chinese family with POI.

HIGD1A Alleviates Oxidative Stress Related Ovarian Hypofunction by Enhancing Granulosa Cell Functions via NF‐κB/SOD2 Signaling Pathway

Advanced Science
Diminished ovarian reserve (DOR) is a physiological or pathological condition that progresses in an age‐dependent manner, which is characterized by impaired ovarian follicle quality, decreased anti‐Müllerian hormone levels, elevated follicle‐stimulating ...

A New Diagnostic Strategy for Polycystic Ovary Syndrome Combining Japanese and International Diagnostic Criteria Using Anti‐Müllerian Hormone

Journal of Obstetrics and Gynaecology Research, Volume 52, Issue 5, May 2026.
ABSTRACT Aim We had defined the anti‐Müllerian hormone (AMH) cut‐off value level 2 aligned with the Rotterdam/International Evidence‐based Guideline (IEBG) for the Assessment and Management of polycystic ovary syndrome (PCOS) 2023 criteria. In this study, we evaluated the utility of AMH cut‐off value level 2 in patients who could not be diagnosed under

Innate Immunity and Microbial Recognition in Reproduction: From Barrier Defense to Maternal–Fetal Tolerance

The FASEB Journal, Volume 40, Issue 8, 30 April 2026.
Graphical abstract illustrating the barrier defense–tolerance framework of reproductive innate immunity. Across the female and male reproductive tracts and the maternal–fetal interface, epithelial barriers, innate sensors, immune cells, and microbial signals are integrated to preserve reproductive homeostasis.

Aberrant DNMTs Promote TXNIP Upregulation and Ovarian Fibrosis in PCOS

The FASEB Journal, Volume 40, Issue 7, 15 April 2026.
In a rat model of DHEA/DHT‐induced PCOS and in granulosa cells (GCs), upregulated DNMT1, DNMT3A, and DNMT3B inhibit TXNIP degradation, leading to TXNIP accumulation, which drives ovarian fibrosis and tissue injury. ABSTRACT Hyperandrogenism and elevated thioredoxin‐interacting protein (TXNIP) are potential causes of infertility in women with polycystic
