Development of a nomogram for sperm retrieval at microTESE for idiopathic non‐obstructive azoospermia in a multi‐center cohort study

Andrology, EarlyView.
Abstract Background Non‐obstructive azoospermia (NOA) affects approximately 10% of infertile men and represents a major challenge in assisted reproductive technology (ART). A model that includes histological variants could be helpful in predicting sperm retrieval rate (SRR) after microdissection testicular sperm extraction (mTESE) in patients affected ...

Lactate inhibits glucose‐induced zigzag motility and enhances linear motility in bull spermatozoa by suppressing glycolysis

Andrology, EarlyView.
Abstract Background Energy metabolism and substrate balance are critical determinants of sperm motility and fertility. Linear motility is necessary for sperm forward movement, whereas hyperactivated motility is a prerequisite for fertilization. The preference of metabolic pathways depends on substrate availability which controls sperm motility. However,

The sensory penis: A comprehensive immunohistological and ontogenetic exploration of human penile innervation

Andrology, EarlyView.
Abstract Background Penile sexual sensation relies on intricate neural structures that remain incompletely characterized. Immunohistological insights into their development and organization can enhance understanding of penile neuroanatomy and function, while optimizing surgical outcomes.

Associação entre proteínas do plasma seminal, motilidade e viabilidade espermática em coelhos submetidos a doping genético Association among seminal plasma proteins, sperm motility and sperm viability in rabbits submitted to gene doping

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2013
Neste trabalho foi estudada a correlação entre o perfil proteico do plasma seminal e a motilidade e viabilidade espermática em coelhos submetidos ao tratamento com vetores de expressão contendo o gene da eritropoetina (EPO) e com EPO recombinante humana.

The Oxytocin Receptor in Spermatozoa May Originate From Both Spermatogenesis and Epididymal Maturation, and Regulates Capacitation

Andrology, EarlyView.
Abstract Background The oxytocin receptor (OR) is a G‐protein‐coupled receptor recently identified in human spermatozoa, whose origin and role in sperm physiology remain unknown. Objectives In this study, using the pig as a model, we examine the presence of the OR in ejaculated spermatozoa through immunofluorescence and immunoblotting, and investigate ...
