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

open access: yesAndrology, 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

open access: yesAndrology, 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,

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

open access: yesAndrology, 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.

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

open access: yesAndrology, 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 ...

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

open access: yesAndrology, 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 ...
