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 ...

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

Ligand-based directed differentiation to produce granulosa-like cells expressing steroidogenic enzyme genes

Stem Cell Research
The ovarian granulosa cells are responsible for producing hormones and supporting oocytes through maturation and meiotic resumption. There is a need to generate granulosa-like cells (GLCs) from human induced pluripotent stem cells (hiPSCs) to better ...

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

Degeneration of postovulatory follicles in the Iberian sardine Sardina pilchardus: structural changes and factors affecting resorption [PDF]

, 2007
Inaccuracy in the aging of postovulatory follicles (POFs) and in estimating the effect of temperature on the resorption rate of POFs may introduce bias in the determination of the daily spawning age classes with the daily egg production method (DEPM). To

Single-Nucleus RNA Sequencing Reveals the Transcriptome Profiling of Ovarian Cells in Adolescent Cyprinus carpio

Animals
The common carp (Cyprinus carpio) is a crucial freshwater species cultivated worldwide for food consumption. Female carp have better growth performance than males, which fascinates scholars to uncover the mechanism of gonadal differentiation and produce ...

In vitro gastrin-releasing peptide response in chicken ovarian follicles

Poultry Science
The gastrin-releasing peptide (GRP) is reported to be mainly produced by the pituitary in chickens, with its receptor (GRPR) highly expressed in the ovaries, indicating its regulatory role in ovarian function. Present study aims to verify the role of GRP
