Molecular markers of sperm quality [PDF]

open access: yesReproduction in Domestic Ruminants, 2010
Light microscopic semen evaluation provides useful information about a given sperm sample, but due to its subjective nature has limited prognostic value for the reproductive performance of males or the outcome of assisted fertilization. Cryptic sperm abnormalities (occurring at the molecular level) are not easily detectable by light microscopy, but can

The impact of percutaneous epididymal sperm aspiration on sperm quality in mice

open access: yesReproduction and Fertility, 2023
In laboratory mice, sperm quality is usually assessed in spermatozoa collected from the cauda epididymidis of freshly sacrificed males. Percutaneous epididymal sperm aspiration (PESA) is a non-terminal alternative that would allow repeated sperm ...
