Male sperm storage impairs sperm quality in the zebrafish [PDF]
Scientific Reports, 2021 Variation in sperm traits is widely documented both at inter- and intraspecific level. However, sperm traits vary also between ejaculates of the same male, due for example, to fluctuations in female availability.

IMSI—Guidelines for Sperm Quality Assessment [PDF]
Diagnostics, 2022 Intracytoplasmic sperm injection (ICSI) is a widely used and accepted treatment of choice for oocyte fertilization. However, the quality of sperm selection depends on the accurate visualization of the morphology, which can be achieved with a high image resolution.

Mitochondria functionality and sperm quality [PDF]
REPRODUCTION, 2013 Although mitochondria are best known for being the eukaryotic cell powerhouses, these organelles participate in various cellular functions besides ATP production, such as calcium homoeostasis, generation of reactive oxygen species (ROS), the intrinsic apoptotic pathway and steroid hormone biosynthesis. The aim of this review was to discuss the putative

Physical activity and sperm quality: influence in sperm donors
Reproductive Biology and Endocrinology, 2022 Abstract Purpose To ascertain whether physical activity (PA) is associated with better sperm quality in sperm donors. Methods A prospective case–control study was designed in an IVF center setting. A total of 207 sperm donation candidates from a relatively small geographical

Molecular markers of sperm quality [PDF]
Reproduction 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
