Towards the Development of a Conceptual Framework of the Determinants of Pre‐Eclampsia: A Hierarchical Systematic Review of Biomarkers

open access: yesBJOG: An International Journal of Obstetrics &Gynaecology, Volume 133, Issue S4, Page S30-S42, September 2026.
ABSTRACT Background Pre‐eclampsia is a leading cause of maternal and perinatal morbidity and mortality. There are several determinants of individual pregnant women's risk of developing pre‐eclampsia, including biomarkers and ultrasound markers. Objective A conceptual framework to collate and summarise the extensive body of literature on biomarkers ...

Ability of human chorionic gonadotropin beta-subunit to inhibit the steroidogenic response to lutropin

open access: yes, 1979
Ability of the beta-subunit of human chorionic gonadotropin to inhibit the response to lutropin (luteinizing hormone, LH) was tested in the immature rat ovarian system and pregnant-mare-serum-gonadotropin-primed rat ovarian system with progesterone ...

Mitochondrial Haplotype Shapes the Trajectory of Ovarian Aging in Genetically Heterogeneous Rats

open access: yesAging Cell, Volume 25, Issue 9, September 2026.
Using genetically heterogeneous rats carrying divergent mitochondrial haplotypes on a randomized nuclear background, we show that mtDNA variation modifies the rate of ovarian aging. OKC‐HETW ovaries showed bioenergetic deficits, reduced mtDNA copy number, and impaired TFAM–mtDNA binding by 4 months of age, with early fibrosis and immune infiltration ...

Testicular SIRT1 Loss Reveals an Aging‐Like Proteomic Landscape and Precipitates Reproductive Deterioration

open access: yesAndrology, Volume 14, Issue 6, Page 1579-1589, September 2026.
ABSTRACT Background Advanced paternal age is associated with reduced male fertility and testicular dysfunction. Among the molecular regulators involved in aging, SIRT1, a NAD+‐dependent deacetylase, plays a pivotal role in maintaining oxidative balance and cellular homeostasis.

Improvement of Mouse Spermatozoa Freezing at −80°C With Ascorbic Acid 2‐Glucoside at Thawing Phase

open access: yesAndrology, Volume 14, Issue 6, Page 1647-1655, September 2026.
ABSTRACT Background Sperm cryopreservation is the most common method to maintain a great number of mutant mouse lines. However, the use of liquid nitrogen (LN2) for freezing presents considerable problems in terms of cost, safety, and accessibility. For this reason, the storage of semen samples at ‐80° in ultra‐freezers has been increasingly used in ...

In Vitro Sperm–Epididymosomes Interaction Immediately Before Fertilization Changes Sperm Fertility Potential

open access: yesAndrology, Volume 14, Issue 6, Page 1757-1770, September 2026.
ABSTRACT Background Sperm acquire fertility ability during epididymal maturation mainly in the epididymal caput and corpus, and once matured, are stored in the epididymal cauda. During storage, interactions with cauda epididymosomes (epEVs) may influence sperm fertility potential; however, the role of such interactions on sperm fertility remains ...
