Sperm Head–Tail Coupling Apparatus Diversity and Common Themes Among Species

Andrology, EarlyView.
ABSTRACT Background A stable connection between the sperm head (containing the nucleus and acrosome) and tail (containing the axoneme, mitochondrial sheath, and periaxonemal structures) is critical for fertility. This connection is mediated by a series of nuclear, cytoplasmic, and centriole components that make up the head–tail coupling apparatus (HTCA)

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.

Sperm Selection Using Micro Swim‐Up: Improvement of Chromatin Integrity Compared to Density Gradient Centrifugation

Andrology, EarlyView.
ABSTRACT Background Selecting high‐quality spermatozoa with optimal nuclear integrity is a crucial step in assisted reproductive technologies (ART). While density gradient centrifugation (DGC) is widely used, the associated centrifugation steps may induce cell stress, potentially damaging sperm DNA.

ZAN, IZUMO1, and TMEM95 Protein Domains Identify the Physiological Status of the Sperm

Andrology, EarlyView.
ABSTRACT Background Infertility is a growing concern, which has led to an increase in the use of assisted reproductive techniques, involving in vitro sperm capacitation. Nonetheless, the optimal capacitation time remains a matter of debate, and it is unknown whether it has an impact on the localization of key membrane proteins.

When two diseases collide: Endometriosis as a risk factor for severe pelvic inflammatory disease

Acta Obstetricia et Gynecologica Scandinavica, EarlyView.
Endometriosis is associated with a more severe clinical course of pelvic inflammatory disease in hospitalized patients, including higher rates of antibiotic treatment failure, longer hospital stay, and increased need for surgical intervention. Abstract Introduction Our objective was to compare the severity of pelvic inflammatory disease (PID) in ...
