Factors affecting sperm recovery rates and survival after centrifugation of equine semen [PDF]
, 2012 Conventional centrifugation protocols result in important sperm losses during removal of the supernatant. In this study, the effect of centrifugation force (400 or 900 × g), duration (5 or 10 min), and column height (20 or 40 mL; Experiment 1); sperm ...

Long-Term Follow Up of the Erectile Function of Testicular Cancer Survivors
Frontiers in Endocrinology, 2019 The diagnosis of testicular cancer (TC) can have a considerable and persistent impact on a patient's sexuality, especially given its location. The high prevalence of TC in young adults, and the good prognosis, explain the great interest in sexual ...

COVID-19 Severity and Androgen Receptor Polymorphism
Biology, 2022 During the COVID-19 pandemic, the most severe form of the disease was most often seen in male patients. The aim of this study was to identify any male predispositions that could be used to predict the outcome of the disease and enable early intervention.

Small RNAs are trafficked from the epididymis to developing mammalian sperm
bioRxiv, 2017 RNAs present in mature mammalian sperm are delivered to the zygote at fertilization, where they have the potential to affect early development. The biogenesis of the small RNA payload of mature sperm is therefore of great interest, as it may be a target ...

Hydrodynamic propulsion of human sperm [PDF]
, 2009 The detailed fluid mechanics of sperm propulsion are fundamental to our understanding of reproduction. In this paper, we aim to model a human sperm swimming in a microscope slide chamber.

Male sperm whale acoustic behavior observed from multipaths at a single hydrophone [PDF]
, 2005 Sperm whales generate transient sounds (clicks) when foraging. These clicks have been described as echolocation sounds, a result of having measured the source level and the directionality of these signals and having extrapolated results from biosonar ...

Human sperm RNA code senses dietary sugar. [PDF]
, 2020 A new study reveals that a high-sugar diet acutely alters human sperm small RNA profiles after 1 week and that these changes are associated with changes in sperm motility.
