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 ...

Women with PCOS have a later menopausal transition and a lower prevalence of menopausal symptoms at age 46: A population‐based birth cohort study

Acta Obstetricia et Gynecologica Scandinavica, Volume 105, Issue 5, Page 836-846, May 2026.
Findings from a population‐based cohort study indicate that late peri−/postmenopausal status, as well as menopausal symptoms, were less prevalent in women with PCOS at age 46, supporting the hypothesis of prolonged ovarian function and a delayed menopausal transition with this condition.

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.

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
