In vivo effects of eurycoma longifolia Jack (Tongkat Ali) extract on reproductive functions in the rat
(Blackwell, 2013)
An aqueous extract of Eurycoma longifolia (Tongkat Ali; TA) roots is traditionally used to enhance male sexuality. Because previous studies are limited to only few sperm parameters or testosterone concentration, this study ...
Inorganic ions in leonotis leonurus extract do not explain changes in isolated Wistar rat heart function
(Open Access Science Research Publisher, 2011)
Leonotis leonurus (L. leonurus) R. Br (Lamiaceae) is used by healers in South Africa. The present study was conducted to determine if the L. leonurus effect on isolated rat heart is due to ionic changes in the perfusion fluid.
Obesity is associated with increased seminal insulin and leptin alongside reduced fertility parameters in a controlled male cohort
(BioMed Central, 2014)
Obesity appears to be associated with male reproductive dysfunction and infertility, although this has been inconsistent and inconclusive. Insulin and leptin are known mediators and modulators of the hypothalamus-pituitary-testes ...
The impact of male overweight on semen quality and outcome of assisted reproduction
(Medknow Publications, 2014)
The impact of obesity on male reproductive health remains a
contested topic as evidence is inconclusive and inconsistent. Even
more debatable is the effect of male obesity in assisted reproduction.
In the manuscript, ...
The effect of sperm DNA fragmentation on intracytoplasmic sperm injection outcome
(Wiley, 2021)
Our study objective was to assess the effect of various sperm DNA fragmentation
levels on clinical intracytoplasmic sperm injection outcome. This retrospective study
included 392 patients who underwent ICSI and performed ...
Male infertility, oxidative stress and antioxidants
(IntechOpen, 2021)
Within the male reproductive system, oxidative stress (OS) has been identified
as prevailing etiology of male infertility. The effects of reactive oxygen species
(ROS) on male fertility depend on the dimensions, “modus ...
Relevance of leukocytospermia and semen culture and its true place in diagnosing and treating male infertility
(Korean Society for Sexual Medicine and Andrology, 2021)
The current WHO 2010 manual for human semen analysis defines leukocytospermia as the presence of peroxidase-positive
leukocytes at a concentration >1×106
/mL of semen. Granular leukocytes when activated are capable of ...
Sperm morphology assessment in the era of intracytoplasmic sperm injection: Reliable results require focus on standardization, quality control, and training
(Korean Society for Sexual Medicine and Andrology, 2021)
Semen analysis is the first, and frequently, the only step in the evaluation of male fertility. Although the laboratory procedures
are conducted according to the World Health Organization (WHO) guidelines, semen analysis ...
Semiquantitative promoter methylation of MLH1 and MSH2 genes and their impact on sperm DNA fragmentation and chromatin condensation in infertile men
(Blackwell Publishing Ltd, 2021)
To investigate the semiquantitative methylation alterations of MLH1 and MSH2 and the possible association among methylation of MLH1 and MSH2, sperm DNA fragmentation and sperm chromatin condensation in idiopathic ...
Editorial commentary on draft of world health organization sixth edition laboratory manual for the examination and processing of human semen
(Korean Society for Sexual Medicine and Andrology, 2021)
Semen examination is the cornerstone of the evaluation of male fertility potential. Despite its apparent
simplicity, it is a complex series of assessments with
highly variable results that are subject to interpretation. ...
