Lycium barbarum polysaccharides enhance testicular spermatogenesis in d‐galactose‐induced aging rats via calcium signaling

Andrology, EarlyView.
Abstract Background Lycium barbarum polysaccharide (LBP) has long been recognized as having a wide range of beneficial properties for improving proliferation. However, the protective effects and specific mechanisms of d‐galactose‐induced testicular dysfunction in reproductively senescent rats are not fully understood.

INSL3 Expression in Leydig Cells is a Biomarker for Immunocastration in Boars: Transcriptional Evidence

Andrology, EarlyView.
ABSTRACT Background Study aimed to obtain insights into physiological responses to immunocastration in pubertal boars by evaluating effects of alternative vaccination protocols and identifying a reliable immunocastration biomarker. Objectives It was hypothesized that the timing of gonadotropin‐releasing hormone (GnRH) suppression by immunocastration ...

Healthy Aging Men Do Not Suffer From Relevant Limitations of Their Reproductive Functions

Andrology, EarlyView.
Abstract Background While metabolic disorders are well‐established contributors to testosterone decline and erectile dysfunction (ED), little is known about the natural progression of reproductive parameters in healthy aging men. Objectives This study aimed to evaluate longitudinal changes in reproductive parameters and sought to determine the ...

Seminal Plasma Exosomal miRNA Profiling Reveals hsa‐miR‐7‐5p as a Key Regulator of Sperm Motility in Asthenozoospermia

Andrology, EarlyView.
ABSTRACT Background Asthenozoospermia is a significant contributing factor to male infertility. Accumulating evidence indicates that impaired sperm motility is closely linked to dysregulated microRNA expression during spermatogenesis. Seminal plasma exosomes are enriched with diverse microRNAs, which play pivotal roles in modulating sperm motility, the

Sleep-wake cycle effects on sleep stages, and plasma cortisol and growth secretions [PDF]

Studies were made of the effects of various stimuli on sleep stages and of secretion of a number of different hormones during sleep in human subjects. Among the stimuli were vestibular stimulation, the action of L-Dopa, and a three-hour sleep-wake cycle.

Homo sapiens, industrialisation and the environmental mismatch hypothesis

Biological Reviews, EarlyView.
ABSTRACT For the vast majority of the evolutionary history of Homo sapiens, a range of natural environments defined the parameters within which selection shaped human biology. Although human‐induced alterations to the terrestrial biosphere have been evident for over 10,000 years, the pace and scale of change has accelerated dramatically since the onset
