Mammalian sperm, the only cells that achieve their purpose outside their organism of origin,
have to swim vigorously within the female reproductive tract to reach an oocyte. Flagellar …

Simple Summary Proton nuclear magnetic resonance spectroscopy (1 H-NMR) is of special
interest for the analysis of metabolites present in seminal plasma and spermatozoa. This …

The mammalian skin exhibits a rich spectrum of evolutionary adaptations. The
pilosebaceous unit, composed of the hair shaft, follicle, and the sebaceous gland, is the …

Background Habitat transitions have considerable consequences in organism homeostasis,
as they require the adjustment of several concurrent physiological compartments to maintain …

The nuclear factor-κB (NF-κB) signaling pathway regulates specific immunological
responses and controls a wide range of physiological processes. NF-κB inhibitor alpha …

Background Mammalian spermatozoa need to undergo a process named capacitation to be
able to fertilize an oocyte. During their journey in the female tract, spermatozoa obtain …

Males and females of many species store sperm for extended periods. During storage,
sperm are predicted to undergo cellular and functional changes, especially towards …

Vestigial organs are historical echoes of past phenotypes. Determining whether a specific
organ constitutes a functional or vestigial structure can be a challenging task, given that …

The Mammalia skin exhibits a rich spectrum of evolutionary adaptations. The pilosebaceous
unit, composed of the hair shaft, follicle, and the sebaceous gland, is the most striking …

Mammalian sperm have long been known to use energy derived from the metabolism of
sugars and fatty acids. A new study shows that sperm of dolphins and their relatives lost …
