A recent paper in the European Journal of Epidemiology reported that recurrent miscarriage and stillbirths are associated with the occurrence of dementia, but there was insufficient evidence to establish such a connection between infertility and dementia [1]. Sex-specific differences in dementia risk Dementia affects women more frequently than men. The authors of this paper discuss...

A recent paper has investigated the impact of polystyrene nanoplastics on the molecular processes of male reproductive tissues in mice [1]. Health risks of micro- and nanoplastics Microplastic and nanoplastic contamination is a worldwide public health concern for a good reason. Numerous research papers have associated microplastics with multiple health risks in the respiratory, immune,...

Experiments in mouse models show the efficacy and safety of mesenchymal stem cell transplantation in treating ovarian aging [1]. Mesenchymal stem cells as a therapy Mesenchymal stem cells (MSCs) are stem cells derived from mesodermal tissue, such as the umbilical cord, umbilical cord blood, the placenta, fat tissue, and bone marrow [2]. MSCs are a...

In a recent Pharmaceutical Research paper, the researchers explored the molecular processes through which the NAD+ precursors NMN and NR reversed ovarian aging in middle-aged rats [1]. Use it or lose it Female fertility decreases rather quickly in life. Aging leads to a decrease in the number and quality of oocytes, and fertilization success declines...

A recent paper published in Nature Aging dives into the gene expression differences between young, middle-aged, and older human ovaries and tests possible interventions to slow down their aging processes [1]. An underexplored area of human aging Female reproductive aging remains a relatively unexplored area of study. With people living longer and females postponing childbearing,...

Experimenting in vitro and in mice, scientists have found that ovarian aging is linked to increased autophagy and apoptosis in granulosa cells and that it can be reversed by an estrogen receptor inhibitor [1]. When ovaries get tired Female reproductive aging is an intriguing phenomenon that remains understudied, although things have been changing recently. In...
