ABSTRACT Background Lower testosterone concentrations in older men are associated with poorer health outcomes. Objective We examined whether, on a background of lifestyle intervention, testosterone treatment modulates leucocyte telomere length, a postulated marker of biological ageing, in overweight men with impaired glucose tolerance (IGT) or newly ...

Spatiotemporal Expression of ARRDC5 in Mammalian Spermatogenesis
ABSTRACT Background Spermiogenesis is the final phase of sperm development during which haploid round spermatids transform into specialized spermatozoa and occurs across distinct stages of sperm production in the seminiferous epithelium. Abnormalities in this process lead to malformations and an inability of sperm to fertilize eggs.

Bone Health and Aging in Klinefelter Syndrome
ABSTRACT Klinefelter syndrome (KS) is typically diagnosed in young adults, but advances in prenatal testing have led to its recognition at a much earlier age. Conversely, diagnosis in late adulthood remains uncommon, but still occurs. Independently from the age at diagnosis, KS individuals now receive more accurate and tailored care management than in ...

Drp1 Phosphorylation Is Indispensable for Steroidogenesis in Leydig Cells
The initial steps of steroidogenesis occur in the mitochondria. Dynamic changes in the mitochondria are associated with their fission and fusion. Therefore, understanding the cellular and molecular relationships between steroidogenesis and mitochondrial ...

The Impact of Common Medications on Male Fertility: An Updated Systematic Review
ABSTRACT Background Compared with those of cytotoxic treatments, the potential effects of common medications on the fertility of men trying to conceive currently or planning to conceive in the future are less well described. The use of common medications may modify the gonadotropic axis, spermatogenesis, and epididymal maturation or alter male ...
