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 ...

Dihydrotestosterone Is a Peripheral Paracrine Hormone [PDF]

Journal of Andrology, 1992
ABSTRACT: Androgen action in sexual tissues, especially skin and the prostate, is expressed by dihydrotestosterone (DHT) acting at the nuclear level. Dihydrotestosterone in the circulation and target tissues is almost solely derived from the peripheral conversion of secreted testosterone (T) in men and androstenedione in women.

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

Transdermal Dihydrotestosterone Treatment of 'Andropause'

Annals of Medicine, 1993
Male ageing coincides on average with progressive impairment of testicular function. The most striking plasma changes are an increase in sex hormone binding globulin (SHBG) and a decrease in non SHBG-bound testosterone, which is the only testosterone subfraction effectively bioavailable for target tissues.

Intramuscular pathways of maladaptation in overtraining syndrome

The Journal of Physiology, EarlyView.
Abstract figure legend The transition from adaptive overreaching to maladaptive overtraining and mechanisms through which excessive training load can lead to performance decline. Four interconnected pathophysiological domains are highlighted: neural fatigue, involving both central and peripheral components such as altered sensory feedback and reflex ...
