Sperm Competition, Sperm Numbers and Sperm Quality in Muroid Rodents [PDF]
PLoS ONE, 2011 Sperm competition favors increases in relative testes mass and production efficiency, and changes in sperm phenotype that result in faster swimming speeds. However, little is known about its effects on traits that contribute to determine the quality of a whole ejaculate (i.e., proportion of motile, viable, morphologically normal and acrosome intact ...

Male sperm storage impairs sperm quality in the zebrafish [PDF]
Scientific Reports, 2021 AbstractVariation 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. Variability in the opportunities to mate can indeed have important consequences for sperm traits, as it determines how often sperm ...

Sperm Competition Selects for Sperm Quantity and Quality in the Australian Maluridae
PLoS ONE, 2011 When ejaculates from rival males compete for fertilization, there is strong selection for sperm traits that enhance fertilization success. Sperm quantity is one such trait, and numerous studies have demonstrated a positive association between sperm competition and both testes size and the number of sperm available for copulations.

A Sperm Quality Detection System Based on Microfluidic Chip and Micro-Imaging System
Frontiers in Veterinary Science, 2022 Sperm quality assessment is the main method to predict the reproductive ability of livestock. The detection of sperm quality of livestock is of great significance to the application of artificial insemination and in vitro fertilization.

Status of Sperm Functionality Assessment in Wildlife Species: From Fish to Primates
Animals, 2021 (1) Background: in order to propagate wildlife species (covering the whole spectrum from species suitable for aquaculture to endangered species), it is important to have a good understanding of the quality of their sperm, oocytes and embryos. While sperm

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.

Glutathione S-transferase Mu 3 is associated to in vivo fertility, but not sperm quality, in bovine
Animal, 2022 In the dairy breeding industry, pregnancy of dairy cows is essential to initiate milk production, so that high fertility rates are required to increase their productivity.

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