Normal morphology according to the World Health Organisation criteria was significantly lower in patients aged >45years. From a linear regression analysis, semen volume, sperm concentration and motility decreased by 0.01mL, 2.1%, and 0.27%, respectively, per year, and the FSH level increased by ...

Image acquisition frame: low and middle sperm concentration collected at 20 Hz, and high sperm concentration at 7 Hz; acquisition interval: 3 ms; maximum sperm motile velocity: 200 μm s−1; area range of spermatozoa head detected at 7–60 μm2. Index of sperm motility: straight line ...
Parameter Normal value Ejaculate volume ≥ 1.5 mL Sperm concentration ≥ 15 mln/mL Sperm total count ≥ 39 mln Motility (forward movement) > 32% Normal morphology (sperm structure/look) ≥ 4% Vitality (live sperm) ≥ 58% Your doctor may also asses a few other semen properties, which are...
A positive correlation was found between the results of the hamster test and three other parameters of the semen analysis: the sperm concentration, the progressive type of motility, and a pH range of 7.2-7.7, but these positive correlations were statistically insignificant. 展开 ...
Although the size of the eggs produced by triploid recipients that received in vitro-expanded ASGs was slightly smaller than those produced by normal diploid female trout (2N cont), the triploid recipient egg sizes were still within the normal range for rainbow trout18 (Fig. 4b). The milt ...
A study was performed comparing motion characteristics of 30 semen samples falling in a normal range before and after cryopreservation in cryoprotector medium (CM). A mean motility rate of recovery (MRR) of 45% was obtained. Only sperm count and concentration in motile forms among initial semen...
the protein was present at very low levels in mature testes ofTex101−/−mice, 2)Ly6kmRNA level was within the normal range inTex101−/−mice, 3)Ly6kmRNA was translated into a polypeptide in the testes ofTex101+/+andTex101−/−mice and 4) TEX101, as well as Ly6k, are ...
The median and interquartile range (IQR) values for the semen parameters were: 73.8 × 106 spz. (27.9 × 106−125.5 × 106) for total sperm count, 24.1 × 106 spz./ml (10.8 × 106−43.1 × 106) for sperm concentration, 79.2% (72.3–84–8%) ...
