Cissampelos capensis is commonly known by the Afrikaans name ‘dawidjies’ or ‘dawidjieswortel’. C. capensis is the most important and best-known medicinal plant of the family Menispermaceae used by the Khoisan and other ...
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, ...
Automation of human semen analysis using a novel artificial intelligence optical microscopic technology
(Wiley Online Library, 2019)
Current semen analysis still commonly depends on a manual microscopy method in clinical laboratories worldwide. However, some of the major disadvantages of this technique are that it is labour‐intensive, subjective, ...
Tunel assay: establishing a sperm dna fragmentation cut-off value for Egyptian infertile men
(Wiley Online Library, 2019)
Male factor infertility is responsible for half of all infertility cases. Conventional semen analysis is inadequate to evaluate male fertility. Sperm DNA fragmentation (SDF) test can be done by: direct methods such as ...

Critical evaluation of two models of flow cytometers for the assessment of sperm DNA fragmentation: an appeal for performance verification
(Medknow Publications, 2019)
Lack of standardized, reproducible protocols and reference values is among the challenges faced when using new or upgraded
versions of instruments in reproductive laboratories and flow cytometry. Terminal deoxynucleotidyl ...
Effects of temperature and storage time on the motility, viability, DNA integrity and apoptosis of processed human spermatozoa
(Wiley, 2019)
The aim of this study was to evaluate motility, viability, DNA integrity and apoptosis of
spermatozoa when washed semen samples were kept for up to 12 days at 4–6°C and
25°C. In this experimental study, 26 normozoospermic ...
