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 ...
Repair of experimental varicoceles in the rat. Long-term effects on testicular blood flow and temperature and cauda epididymidal sperm concentration and motility
varicocele varicocele repair rat testis
2009/2/23
The effects of varicocele and varicocele repair on testicular blood flow, temperature, sperm counts, and sperm motility were assessed in adult male rats. The duration of the experimental varicocele ...
Evaluation of computer-assisted semen analysis（CASA）with IDENT stain to determine sperm concentration
Sperm count sperm density CASA
2009/2/16
This study was undertaken to compare a new fluorescent stain-based computer-assisted semen analysis (CASA) system (IDENT) for determining human sperm concentration to the manual hemacytometric met...
Methodological issues in the analysis of human sperm concentration data
Sperm concentration log transformation multiple sampling variation statistical power

We examined two methodological issues in the analysis of sperm concentration data using a large database of sperm concentrations in healthy men that were collected at the University of Washington....
Evaluation of flow cytometric methods to measure human sperm concentration
Semen cell count DNA staining fluorospheres hemocytometry
2008/12/29
Human sperm concentration is usually assessed using hemocytometry (HM). However, external and internal quality control schemes have shown that the accuracy of this method is low overall. Flow cyto...
Seminal Plasma Cobalamin Significantly Correlates With Sperm Concentration in Men Undergoing IVF or ICSI Procedures
Assisted reproduction folate homocysteine semen analysis
2008/12/24
Mild hyperhomocysteinemia is caused by B vitamin deficiencies. We hypothesize that these biochemical derangements detrimentally affect spermatogenesis. Therefore, the aim of this study was to inv...
