Impact of body composition analysis on male sexual function: A metabolic age study
(Frontiers Media, 2023)Metabolic Age (MetAge) and body composition analysis may reflect an individual’s metabolic status, which is believed to influence male sexual and gonadal functions. Although erectile dysfunction (ED) and hypogonadism ... -

Impact of climate change and anthropogenic activities on renewable coastal resources and biodiversity in Nigeria
(Academic Journals, 2012)Climates related disaster is greatly human induced warming, leading to substantial fluctuations in earth temperature which is currently a global issue of environmental concern. Human proximity and pressure in and around ... -
The impact of COVID-19 on the male reproductive tract and fertility: A systematic review
(Informa UK Limited, trading as Taylor & FrancisGroup., 2021)Objective: The COVID-19 pandemic, caused by the acute respiratory syndrome-coronavirus 2 (SARS-CoV-2), remains an ongoing public health challenge. Although males are affected slightly more than females, the impact of ... -
The impact of Covid-19 vaccines on male semen parameters: A retrospective cohort study
(University of the Western Cape, 2023)The emergence of SARS-CoV-2 and the subsequent COVID-19 pandemic necessitated the development of adequate vaccines. Despite vaccines being demonstrated to be safe and effective for preventing severe disease and death, ... -
The impact of detrital minerals on reservoir flow zones in the North Eastern Bredasdorp basin, South Africa, using core data
(MDPI, 2022)The present study uses core data to group reservoirs of a gas field in the Bredasdorp Basin offshore South Africa into flow zones. One hundred and sixty-eight core porosity and permeability data were used to establish ... -

The Impact of Health Disparities on COVID-19 Outcomes: Early Findings from a High-Income Country and Two Middle-Income Countries
(Springer, 2021)The SARS-CoV-2 infection, which causes the coronavirus disease (COVID-19), has affected lives, with very adverse outcomes in specific populations in the United States of America (USA), a high-income country, and two ... -
The impact of ICT Investments on human development: a regression splines analysis
(Taylor & Francis, 2013)Despite the worldwide growth in investments in information and communication technology (JCT), few studies have investigated the complex interactions between components of JCT investments and different dimensions of human ... -
The impact of land-use/land cover changes on water balance of the heterogeneous Buzi sub-catchment, Zimbabwe
(Elsevier, 2020)The nature of interactions between ecological, physical and hydrological characteristics that determine the effects of land cover change on surface and sub-surface hydrology is not well understood in both natural ... -
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, ... -
Impact of metagenomic DNA extraction procedures on the identifiable endophytic bacterial diversity in Sorghum bicolor (L. Moench)
(Elsevier, 2015)Culture-independent studies rely on the quantity and quality of the extracted environmental metagenomic DNA (mDNA). To fully access the plant tissue microbiome, the extracted plant mDNA should allow optimal PCR applications ... -
The impact of mitochondrial impairments on sperm function and male fertility: a systematic revie
(BMC, 2024)Background Besides adenine triphosphate (ATP) production for sustaining motility, the mitochondria of sperm also host other critical cellular functions during germ cell development and fertilization including calcium ... -

The Impact of Observing Strategy on Cosmological Constraints with LSST
(2022)The generation-defining Vera C. Rubin Observatory will make state-of-the-art measurements of both the static and transient universe through its Legacy Survey for Space and Time (LSST). With such capabilities, it is immensely ... -
The impact of quenching on galaxy profiles in the SIMBA simulation
(Oxford University Press, 2020)We study specific star formation rate (sSFR) and gas profiles of star-forming (SF) and green valley (GV) galaxies in the SIMBA cosmological hydrodynamic simulation. SF galaxy half-light radii (Rhalf) at z = 0 and their ... -
Impact of Rubin observatory cadence choices on supernovae photometric classification
(American Astronomical Society, 2023)The Vera C. Rubin Observatory’s Legacy Survey of Space and Time (LSST) will discover an unprecedented number of supernovae (SNe), making spectroscopic classification for all the events infeasible. LSST will thus rely on ... -

The impact of solar wind variability on pulsar timing
(EDP Sciences, 2021)Context. High-precision pulsar timing requires accurate corrections for dispersive delays of radio waves, parametrized by the dispersion measure (DM), particularly if these delays are variable in time. In a previous paper, ... -
The impact of sperm DNA damage in assisted conception and beyond: recent advances in diagnosis and treatment
(Elsevier, 2013)Sperm DNA damage is a useful biomarker for male infertility diagnosis and prediction of assisted reproduction outcomes. It is associated with reduced fertilization rates, embryo quality and pregnancy rates, and higher ...
