The evaluation of infertility in males consists of physical examination and semen analyses. Standardized semen analyses depend on the descriptive analysis of sperm motility, morphology, and concentration, with a threshold level that must be surpassed to be considered a fertile spermatozoon. Nonetheless, these conventional parameters are not satisfactory for clinicians since 25% of infertility c...

tau.amegroups.com © Translational Andrology and Urology. All rights reserved. Conventional semen analysis is the routine test performed during the evaluation of a couple’s fertility status. The test is cost-effective and easy to perform and at the same time provides essential information on quantitative semen parameters such as semen volume, sperm motility, concentration, viability and morpholo...

BACKGROUND Recent data emphasized the implication of polymerase gamma (POLG) CAG repeats in infertility, making it a very attractive gene for study. A comparison of POLG CAG repeats in infertile and fertile men showed a clear association between the absence of the usual 10-CAG allele and male infertility, excluding azoospermia. It has also been suggested that the POLG gene polymorphism should b...

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...

Dr. Sandro Esteves and collegues, from Brazil, performed on page xx at this issue of the International Braz J Urol an elegant review that discuss how the new World Health Organization (WHO) criteria for seminal parameters could affect the clinical management of men presenting with male infertility. The authors emphasized the factors that limit the use of seminal parameters as a surrogate for ma...

Male factor is a common cause of infertility and the male partner must be systematically evaluated in the workup of every infertile couple. Various Eastern medical strategies have been tried with variable success. This article describes the clinical effects of Eastern medicine approaches including acupuncture, Chinese herbal medicine, massage, yoga, tai chi, and qi gong, which could improve the...

background: to determine any correlation between infertility and semen quality with concentrations of l-carnitine in human seminal plasma. methods: this case-control study performed in fatemieh hospital in hamadan, iran. seminal plasma of 72 infertile men and 80 men with proved fertility as a control group was investigated and l-carnitine level was determined using uv enzymatic test at 340 nm. ...

background: wide range of disorders ranging from genetic disorders to coital difficulties can influence male fertility. in this regard, genetic factors are highlighted as the most frequent, contributed to 10-15%, of male infertility causes. objective: to investigate the influence of genetic abnormalities on semen quality and reproductive hormone levels of infertile men from northeast china. mat...

Male infertility is a multifactorial syndrome encompassing a wide variety of disorders. In recent years, several genome-wide single-nucleotide polymorphism (SNP) association studies (GWAS) have been performed on azoospermia and/or oligozoospermia in different populations including two GWAS on nonobstructive azoospermia in China; however, the association of SNPs with idiopathic male infertility,...

Infertility among couples in Nigeria is causing increasing concern. Investigations have shown a relationship between abnormalities in spermatozoa/semen parameters and the incidence of male factor mediated fertility problems in couples. However, the factors responsible for the sudden increase in semen/spermatozoa abnormalities are not fully understood. In this study, blood and semen samples were...
