Systems Biology in Reproductive Medicine, 2021
An appropriate preparation technique, should be capable of isolating highquality spermatozoa for intracytoplasmic sperm injection (ICSI). The aim was to assess sperm quality parameters, DNA integrity, embryo development, and clinical outcomes using a ...

Fish egg quality can be defined as the ability of the egg to be fertilized and subsequently develop into a normal embryo. Similarly, sperm quality can be defined as its ability to successfully fertilize an egg and subsequently allow the development of a normal embryo.

Amelioration of heat stress-induced damage to testes and sperm quality.
Theriogenology, 2020Heat stress (HS) occurs when temperatures exceed a physiological range, overwhelming compensatory mechanisms. Most mammalian testes are ∼4-5 °C cooler than core body temperature.

Cigarette smoking and sperm quality*
Andrologia, 2009The effect of cigarette smoking on conventional semen parameters (volume, total sperm count, sperm count/ml, total motility, progressive motility, morphology) was studied retrospectively in 90 healthy patients (50 non-smokers, 40 smokers) of our infertility clinic.

Sperm Selection: Effect on Sperm DNA Quality
2013The selection of spermatozoa without DNA fragmentation and chromosomal diseases prior to assisted reproductive techniques helps to optimize the outcome of the treatment; in particular, sperm selection prior to in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) is crucial.

Assessment of the Sperm Quality Analyzer
Fertility and Sterility, 1995To assess the relationship between the results of the Sperm Quality Analyzer (United Medical Systems Inc., Santa Ana, CA), which measures motile sperm concentration by light scattering, conventional manual semen analysis characteristics, and computer-assisted sperm motility analyses.Sperm Quality Analyzer measurements and manual and computer-assisted ...

Stability of sperm characteristics in men with disturbances in sperm quality
International Journal of Andrology, 1989SummarySixty‐one men referred to our laboratory for semen analysis, and subsequently judged to exhibit some form of sperm pathology, were asked to return for a second analysis, not less than 2 months after the first, in order to assess the stability of the pathological changes observed.

Sperm hyperactivation as quality control for sperm penetration assay
Urology, 1992The sperm penetration assay (SPA) is subject to considerable variation, and controls are needed to verify the accuracy of the results. It is proposed that sperm hyperactivation (HA) can serve as a quality control check for the SPA. The objective was to determine if there was an association between the SPA outcome and sperm HA measured at various times ...
