Genetic correlations between production traits (average daily gain from birth till the end of the field test and ultrasonically predicted lean meat content at the end of the field test) and semen traits (semen volume, sperm concentration, motility, percentage of abnormal spermatozoa, total number of spermatozoa and number of functional spermatozoa) were estimated from a large dataset (44 500 ob...

BACKGROUND The aim of this study was to analyse the semen quality of patients before and after gonadotoxic therapy. PATIENTS AND METHODS We evaluated semen quality in 314 patients over a 26 year period. The diagnostic categories were leukaemia (n = 13); lymphoma (n = 128); testicular cancer (n = 102); benign conditions (n = 13); and other malignant neoplasms (n = 58). The degree of azoospermi...

INTRODUCTION Although genital tuberculosis is a condition that is prevalent worldwide, it is still a diagnostic dilemma. This study aimed to find an effective diagnostic modality for the condition. METHODS A total of 100 infertile women were clinically evaluated with haemoglobin estimation, total and differential count, Mantoux test, tubercle bacilli enzyme-linked immunosorbent assay (TB ELIS...

tau.amegroups.com © Translational Andrology and Urology. All rights reserved. World Health Organization (WHO) defines infertility as the inability of a sexually active, non-contraceptive couple to achieve pregnancy in 1 year (1). Overall, the worldwide incidence is about 15 % and a male factor is responsible in 20–50% of cases (2). Medical history, physical examination and semen analysis remain...

The aim of this study was to investigate whether the quality of semen has deteriorated during the last decade. Laboratory records containing semen analysis results were reviewed. The records, arranged according to date of birth, are kept in shelves. Every fifth record for analyses performed between 1985 and 1995, and only those of men in infertile relationships, were included. The data were abs...

We studied the diagnostic predictive power of transrectal ultrasonography (TRUS) coupled with semen volume in cases of distal seminal tract sub-obstruction. As a gold standard for diagnosis we used seminal tract washout (STW). Non-azoospermic subjects (n = 112) were submitted to transrectal ultrasonography because of suspected excretory infertility or other andrological pathologies, before perf...

background: human pathogens that can cause infertility may also affect sperm count and quality. viral infections can be considered as direct and/or indirect cause of male factor infertility. objective: our goal was to investigate the prevalence of herpes simplex virus in the semen of infertile men attending the avicenna infertility clinic, and to compare it with the herpes virus serology result...

The effect of seminal plasma, as well as some seminal plasma fractions, on the heterogeneity and viability of frozen-thawed ram spermatozoa was studied. Fresh and frozen sperm samples were simultaneously assessed by a routine semen-quality assay and centrifugal countercurrent distribution (CCCD) in an aqueous two-phase system analysis. All samples used for this study were obtained from Salz ram...
