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.

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 ...

What Moves Men to Change? A Mixed‐Methods Study on Facilitators and Barriers of Lifestyle Changes in Men Seeking Fertility Care

Andrology, EarlyView.
ABSTRACT Background An unhealthy lifestyle negatively affects male fertility. Despite this, men that are part of an infertile couple often fail to improve their lifestyle and evidence on influencing factors is limited. Objectives To identify facilitators and barriers involved in lifestyle changes of men seeking fertility care and in lifestyle ...

CRISPR/Cas9‐mediated Genome‐editing Reveals 10 Testis‐enriched Genes and One Non‐testis‐enriched Gene are Dispensable for Male Fecundity in Mice

Andrology, EarlyView.
ABSTRACT Background More than 1000 genes have been identified as predominantly expressed in the human testis. Advances in gene editing technologies have enabled the rapid and efficient generation of genetically engineered mice. This approach facilitates the screening of genes essential for spermatogenesis by analyzing knockout mouse models.

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 ...

Sperm Telomere Interactions Are Impaired in Testicular Cancer Before and After Adjuvant Therapy

Andrology, EarlyView.
ABSTRACT Background No study has yet explored telomere length or interaction in sperm nuclei of testicular cancer (TC) patients exposed to chemotherapy or radiotherapy. However, sperm telomere dynamics have emerged as a potential marker in male infertility.

The Ticking Clock: Differential Time‐Dependent Deterioration Between Washed and Thawed Sperm

Andrology, EarlyView.
ABSTRACT Background Cryopreservation is widely used in assisted reproductive technologies. While fresh sperm undergoes gradual time‐dependent deterioration, it remains unclear whether thawed sperm exhibits a more accelerated decline. Objectives To directly compare the rate of deterioration in sperm motility, vitality, and DNA fragmentation between ...

Pig Seminal Plasma Extracellular Vesicles Enhance Motility During Preservation of Epididymal Spermatozoa but Impair Capacitation and IVF Parameters

Andrology, EarlyView.
ABSTRACT Background Extracellular vesicles (EVs) produced by accessory sex glands play a key role in sperm functionality, influencing motility, viability, acrosome integrity, metabolic activity, and capacitation. Most studies on the effects of EVs on spermatozoa have focused on ejaculated spermatozoa, which have already been exposed to their own native
