Improving ARTs: Microfluidics as a Tool for Sperm Selection

Andrology, EarlyView.
ABSTRACT Sperm selection is a critical step in assisted reproductive technology (ART), as sperm quality directly influences embryo quality. In vivo, the female reproductive tract imposes several physical and physiological barriers that favors only the most optimal spermatozoa reaching the fertilization site.

Rat dorsal prostate is necessary for vaginal adhesion of the seminal plug and sperm motility in the uterine horns

Biological Research, 2011
The rat prostate comprises dorsal, ventral and lateral lobes that are morphologically and biochemically distinct. Lesions to these structures are expected to affect the quality of the ejaculate and male fertility.

Maternal Consumption of Artificially Sweetened Beverages in Pregnancies and Biomarkers of Fecundity in Adult Sons

Andrology, EarlyView.
ABSTRACT Introduction Maternal intake of artificial sweeteners in beverages (ASB) during pregnancy may have a programming effect on offspring health, including biomarkers of male fecundity. Objective We investigated whether maternal intake of ASB during pregnancy was associated with biomarkers of male fecundity in adult sons.

Sperm Mitochondrial DNA Copy Number and Nuclear DNA Methylation Across Clinical and Non‐Clinical Preconception Cohorts

Andrology, EarlyView.
ABSTRACT Background Sperm mitochondrial DNA copy number is an emerging marker of male fertility, with elevated mtDNAcn associated with poor semen quality across various populations. Sperm DNA methylation has also been previously demonstrated to be negatively correlated with semen parameters in IVF cohorts.

Comparative Testicular Echotexture and Scrotal Thermography Before and After Electroejaculation in Beef Bulls

Applied Sciences
Testicular echotexture and scrotal thermography were evaluated in beef bulls before and after electroejaculation (EE) to assess their response to semen collection and to standardize echotexture assessment methodology.

Role of ANO1‐Expressing PDGFRα+ Smooth Muscle Cells in Generating Spontaneous Phasic Contractions of the Rodent Epididymis

Andrology, EarlyView.
ABSTRACT Background Spontaneous phasic contractions (SPCs) in the epididymal duct play an important role in transport and maturation of sperm. In proximal cauda of the rat epididymis, platelet‐derived growth factor receptor α (PDGFRα)‐positive smooth muscle cells (SMCs) generate ANO1 Ca2+‐activated chloride channels (CaCCs)‐dependent spontaneous ...

Obesity Is an Independent Risk Factor for Oligozoospermia, With Co‐Existing Hyperglycemia Exacerbating Risks of Asthenozoospermia and Elevated Sperm DNA Fragmentation

Andrology, EarlyView.
ABSTRACT Background Metabolic health plays a critical role in maintaining male fertility and may influence offspring health. Therefore, it is necessary to incorporate metabolic indicators into the clinical assessment of male fertility. However, the relationships between different metabolic abnormalities and semen quality remain incompletely understood.

Delayed Ejaculation and Associated Complaints: Relationship to Ejaculation Times and Serum Testosterone Levels

, 2017
Background Although delayed ejaculation (DE) is typically characterized as a persistently longer than anticipated or desired time to ejaculation (or orgasm) during sexual activity, a timing-based definition of DE and its association ...
