An attempt to evaluate the effect of spermatozoa concentration in one ejaculate on their measurements, shape, frequency of occurrence of morphological abnormalities in spermatozoa and physical traits ...
Relationship of Human Sperm Acrosin and Proacrosin to Semen Parameters. I. Comparisons Between Symptomatic Men of Infertile Couples and Asymptomatic Men, and Between Different Split Ejaculate Fractions

2009/2/19
Acrosin is a sperm serine proteinase whose activity appears to be essential for fertilization in mammals, although this has not been shown in man due to experimental limitations. The present stu...
Influence of semen collection method on ejaculate characteristics in the common marmoset, Callithrix jacchus
Spermatozoa electroejaculation vaginal washing artificial insemination
2009/2/16
A source of normal spermatozoa (sperm) is required for many andrological and reproductive studies. Ideally the method used for semen collection should be repeatable and reliable but should not influ...

Electroejaculate traits, testicular volume, and circulating FSH, LH, and testosterone concentrations were compared between two populations of domestic cats consistently producing either a high (grea...
Ejaculate Volume Is Seriously Underestimated When Semen Is Pipetted or Decanted Into Cylinders From the Collection Vessel
Ejaculate Volume Underestimated Semen Pipetted Decanted Into Cylinders Collection Vessel
2008/12/24
The total sperm count (number of spermatozoa per ejaculate) rather than sperm concentration (number of spermatozoa per unit volume of semen) is the more important semen variable related to fertili...
Sperm Nuclear Histone to Protamine Ratio in Fertile and Infertile Men：Evidence of Heterogeneous Subpopulations of Spermatozoa in the Ejaculate
Sperm DNA male infertility
2008/12/24
Sperm protamine deficiency is observed in a subset of infertile men, suggesting that the relative histone to protamine ratio may be altered in the spermatozoa of these men. We measured the ratio of ...
