In vitro evaluation of sperm quality

open access: yesAnimal Reproduction Science, 2008
This paper highlights selected laboratory analyses that are currently used to evaluate sperm, and describes why results from these assays do not consistently correlate with sperm fertility. Reasons for the disconnect between the two are due in part to the definition and reliability of the fertility data collected, to the complexity of the spermatozoon ...

Going beyond conventional parameters to unveil sperm quality in fish: the use of fibre optic technology to assess mitochondrial respiratory performance

open access: yesBiology Open, 2020
Sperm fertilisation success depends on both intrinsic quality and the interactions with the surrounding reproductive fluids. In several fish species, these interactions have a variable effect on sperm performance.

Establishment of a novel assessment of the quality of human spermatozoa measuring mitochondrial oxygen metabolism

open access: yesBMC Research Notes, 2022
Objective We aimed to establish a novel sperm quality evaluation technology by measuring mitochondrial oxygen metabolism in human spermatozoa. Results Normozoospermic human sperm samples were used.

High-Efficiency Bovine Sperm Sexing Used Magnetic-Activated Cell Sorting by Coupling scFv Antibodies Specific to Y-Chromosome-Bearing Sperm on Magnetic Microbeads

open access: yesBiology, 2022
Sperm sexing technique is favored in the dairy industry. This research focuses on the efficiency of bovine sperm sexing using magnetic-activated cell sorting (MACS) by scFv antibody against Y-chromosome-bearing sperm (Y-scFv) coupled to magnetic ...

Effect of L-carnitine on sperm quality during liquid storage of boar semen [PDF]

open access: yesAsian-Australasian Journal of Animal Sciences, 2020
Objective This study was conducted to investigate the effect of L-carnitine on the pig semen characteristics during storage. Methods Spermatozoa samples were examined for spermatozoa quality and then randomly divided into 5 groups: 0 (control), 12.5, 25,

Sperm mobility phenotype not determined by sperm quality index

open access: yesPoultry Science, 2003
We tested the capacity of the AviMate sperm quality analyzer to predict sperm mobility phenotype. A preliminary experiment was performed to determine a sperm concentration that afforded maximal sperm quality index (SQI) values with sperm from males with high sperm mobility.

The impact of percutaneous epididymal sperm aspiration (PESA) 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 collection for sperm quality assessment in living males.

Restoring Sperm Quality Post-Cryopreservation Using Mitochondrial-Targeted Compounds

open access: yesAntioxidants, 2022
While critical for male fertility preservation, cryopreservation damage reduces sperm quality and fertilization potential. This study investigated whether the addition of mitochondrial-targeted, antioxidant compounds, also known as Mitochondrial ...

Association between ambient temperature and semen quality: A longitudinal study of 10 802 men in China

open access: yesEnvironment International, 2020
Semen quality is a vital determinant for male fertility. The process of spermatogenesis is highly sensitive to fluctuations in temperature. However, the impact of ambient temperature on semen quality remains unclear. We aimed to quantitatively assess the

Factors affecting sperm quality before and after mating of calopterygid damselflies. [PDF]

open access: yesPLoS ONE, 2010
Damselflies (Odonata: Zygoptera) have a more complex sperm transfer system than other internally ejaculating insects. Males translocate sperm from the internal reproductive organs to the specific sperm vesicles, a small cavity on the body surface, and ...
