Impact of Sorting and Catch Media on Porcine Sperm Motility, Capacitation, and Viability
Andrology, EarlyView.ABSTRACT Background Fluorescence‐activated cell sorting (FACS) has emerged as a powerful tool for selecting spermatozoa of a desired population of fluorescent biomarkers, offering potential applications in reproductive biology and agriculture. However, concerns remain regarding sorting‐induced physiological alterations that could compromise spermatozoa

Chromodomain Helicase DNA–Binding Proteins and Spermatogenesis: Current Advances
Andrology, EarlyView.ABSTRACT Background Male infertility is a prevalent clinical condition, with approximately one‐third of cases classified as idiopathic, frequently stemming from impaired spermatogenesis because of dysregulated gene expression. Chromodomain helicase DNA‐binding (CHD) proteins are central chromatin remodelers that orchestrate this epigenetic regulation ...

The Challenges and Benefits of an Open Anterior Repair of Recurrent Inguinal Hernias: A Cohort Study
ANZ Journal of Surgery, EarlyView.ABSTRACT Introduction Recurrent inguinal hernia repair presents unique clinical challenges. While minimally invasive surgery (MIS) is often preferred, open anterior mesh repair is a valid approach particularly when requiring mesh, suture, or tack removal. This study evaluates the outcomes of a small incision open anterior mesh repair, including foreign

Sperm competition and fertilization success.
, 2009 AbstractMuch of our understanding of the reproductive physiology of birds is derived from research by poultry biologists. Starting in the 1970s behavioural ecologists began to explore the evolutionary consequences of female promiscuity across a range of taxa, but mainly insects and birds, focusing on the fact that, if females copulate with two or more ...

Sperm Competition in Fish [PDF]
, 2008 Sperm competition, the contest between sperm from rival males for fertilizations, is an important evolutionary force shaping sperm characteristics. Theory predicts that males experiencing elevated levels of sperm competition will invest more in sperm ...
