Objective The quality of semen depends upon several factors such as environment, life style, physical activity, age and occupation. The aim of this study was to analyze and compare the conventional and functional semen parameters in men who practice vigorous physical activity to those of sedentary men. MaterialsAndMethods Semen samples from 17 physically active men and 15 sedentary men were col...

Semen analysis as an integral part of infertility investigations has a surprisingly long history, emerging only slowly, from under a cloud of disrepute and occupying a solitary niche outside conventional pathology tests, until relatively recently. From origins in the 19th century when spermatozoa were only identified as present or absent in cervical mucus samples from postcoital tests, even the...

The present study was conducted to determine the correlation of hypo-osmotic swelling test with conventional semen evaluation parameters of fresh semen collected from two Nili-Ravi buffalo and two Sahiwal cow bulls. A total of 10 pooled samples (each comprising two consecutive ejaculates) from each bull were collected. Each semen sample was divided into two parts. One part was used for the eval...

Boar semen is typically collected, diluted and cooled for AI use over numerous days, or frozen immediately after shipping to capable laboratories. The storage temperature and pH of the diluted, cooled boar semen could influence the fertility of boar sperm. Therefore, the purpose of this study was to determine the effects of pH and storage temperature on fresh and frozen-thawed boar sperm motili...

BACKGROUND Genital ureaplasmas (Ureaplasma urealyticum and Ureaplasma parvum) and mycoplasmas (Mycoplasma genitalium and Mycoplasma hominis) are potentially pathogenic species playing an etiologic role in both genital infections and male infertility. Reports are, however, controversial regarding the effects of these microorganisms infections in the sperm seminological variables. This study aime...

We have undertaken an analysis of semen from HIV infected men with regard to sperm counts and motility, non-spermatozoal cells, and viral nucleic acid. Regression analysis showed that sperm concentration and motility were positively associated with blood CD4 cell count. By contrast, non-spermatozoal cell concentration (round cells) was inversely related to CD4 count. Extracellular HIV RNA was d...

Background: It is estimated that around 15% of the couple at reproductive age are infertile couples, and approximately the half of infertilities are caused by male factor. Defective spermatogenesis is the result of several different disorders, such as endocrinological disorders, disease, malnutrition, genetic defects and maybe environmental condition. Materials and Methods: In this study 60 IVF...

PURPOSE This study was conducted to find the relative risk of semen abnormality with respect to smoking history and obesity. MATERIALS AND METHODS Subfertile or infertile men were enrolled in this study from July 2010 to June 2011. All participants provided their cigarette use information, self-reported weight, height, semen analysis, physical examination, and sexually transmitted disease sta...

Accurate prognosis of male fertility based on semen measurements is still not straightforward. This study was designed to identify the best predictors of fertility and to develop a multiple regression model predicting fertility using selected parameters of semen analysis. The predictive value of standard semen parameters and selected functional tests were studied in 113 fertile men and in 109 s...

Objective To prospectively monitor Zika viral loads in semen from Belgian travellers with confirmed Zika virus infection, who returned from the Americas during the 2016 Zika virus epidemic. Methods We recruited symptomatic travellers consulting our clinic and we confirmed infection with either reverse-transcriptase (RT) polymerase chain reaction (PCR) assay or virus neutralization test. The p...
