Thoracic and Umbilical Endometriosis Concurrently Presenting During Secondary Subfertility Evaluation

open access: yesRespirology Case Reports, Volume 14, Issue 9, September 2026.
We report a case of a 33‐year‐old woman who presented for evaluation of secondary subfertility and pelvic pain and was incidentally found to have concurrent umbilical and pleural endometriosis discovered incidentally on CECT chest and the patient had no respiratory symptoms.

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.

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 ...

Obesity in Classic Congenital Adrenal Hyperplasia: Mechanisms, Complications and Management

open access: yesClinical Endocrinology, Volume 105, Issue 3, Page 271-284, September 2026.
ABSTRACT Classic congenital adrenal hyperplasia (CCAH) is an autosomal recessive genetic disorder primarily caused by 21‐hydroxylase deficiency. Although the survival rate of patients has significantly improved with glucocorticoid replacement therapy, long‐term use of supraphysiological doses and multiple factors inherent to the disease itself have led

Genetic Parameters and Genome‐Wide Association Studies for Fertility and Reproduction Traits in U.S. Katahdin Sheep Based on the Single‐Step GBLUP Methodology

open access: yesJournal of Animal Breeding and Genetics, Volume 143, Issue 5, Page 625-638, September 2026.
ABSTRACT Sheep production contributes to a secure and diverse food and fibre supply in the United States, with growing ethnic diversity strengthening demand. Katahdin is a composite hair‐type sheep breed developed in the United States that has become the most popular breed in many regions of the country and the first one to have genomic selection ...

Periestropause enhances hypoxia‐induced panic and microglial remodelling without altering respiratory control

open access: yesJournal of Neuroendocrinology, Volume 38, Issue 9, September 2026.
Abstract Perimenopause is characterised by irregular reproductive cycles and hormonal fluctuations, notably decreased estradiol (E2), which are linked to increased susceptibility to panic disorder and neuroinflammation. We examined whether panic‐related respiratory and behavioural responses to respiratory challenges vary across reproductive stages ...

Optical control of the hypothalamic arcuate nucleus kisspeptin neuronal network with a photoswitchable peptide that drives luteinizing hormone release in female mice

open access: yesJournal of Neuroendocrinology, Volume 38, Issue 9, September 2026.
Abstract Pulsatile gonadotropin‐releasing hormone (GnRH) and luteinizing hormone (LH) secretion are essential for reproductive function and are thought to be governed by arcuate nucleus kisspeptin Kiss1ARH neurons via neurokinin B (NKB) signaling through TacR3.
