Human asthenozoospermia: Update on genetic causes, patient management, and clinical strategies

Andrology, Volume 13, Issue 5, Page 1044-1064, July 2025.
Abstract Background In mammals, sperm fertilization potential relies on efficient progression within the female genital tract to reach and fertilize the oocyte. This fundamental property is supported by the flagellum, an evolutionarily conserved organelle, which contains dynein motor proteins that provide the mechanical force for sperm propulsion and ...

Neuroactive steroid exposure impacts neurodevelopment: Comparison of human and rodent placental contribution

Journal of Neuroendocrinology, Volume 37, Issue 7, July 2025.
Abstract The placenta is a fetal endocrine organ that secretes many neuroactive factors, including steroids, that play critical roles in brain development. The study of the placenta‐brain axis and the links between placental function and brain development represents an emerging research area dubbed “neuroplacentology.” The placenta drives many ...

Disruption of mc1r Disturbs Skin Pigmentation in Xenopus tropicalis

Pigment Cell &Melanoma Research, Volume 38, Issue 4, July 2025.
ABSTRACT The melanocortin 1 receptor (MC1R) is well‐established as a pivotal regulator of pigmentation in various species. Despite a wealth of research focused on mammals and fish, the role of Mc1r in amphibians has remained largely unexplored. This study was designed to elucidate the contribution of Mc1r in Xenopus tropicalis.

Brain‐Specific Gata4 Downregulation in Greywick Female Mice Models the Metabolic Subtype of Polycystic Ovary Syndrome

The FASEB Journal, Volume 39, Issue 12, 30 June 2025.
In adult Gw female mice, competition between transgenic and endogenous Gata4 promoters leads to decreased Gata4 expression in the hypothalamus while it remains unaffected in the ovaries. The resulting PCOS‐like traits, combining reproductive and metabolic dysfunctions in these mice, support a central (CNS)—not peripheral (ovarian)—mechanism of disease ...
