Ursolic Acid Alleviates Orchitis via Modulating Ferroptosis in Peritubular Myoid Cells of Testis

Animal Research and One Health, EarlyView.
Ursolic acid modulates key ferroptosis‐related pathways in the peritubular myoid cells of the testis in forest musk deer. ABSTRACT Chronic stress adversely affects reproductive health, increasing susceptibility to pathologies such as orchitis. Additionally, the maintenance of iron homeostasis is essential for preserving the function of the testicles ...

Low‐Level Human Epididymis Protein 4 in Seminal Plasma Is an Independent Risk Factor for Poor Semen Liquefaction: A Case Control Study

Journal of Clinical Laboratory Analysis, EarlyView.
Our work identifies a novel and significant association between low seminal levels of Human Epididymis Protein 4 (HE4) and the clinical condition of poor semen liquefaction, a common cause of male infertility. The findings are statistically robust, clinically relevant, and provide a foundational basis for future research into the mechanism by which HE4
