Racial Variation in Semen Quality at Fertility Evaluation

Abstract

To identify racial differences in semen quality among men living in the same geographic area and seeking fertility evaluation. Men obtaining a semen analysis for infertility evaluation or treatment between 2012 and 2016 at a single center were identified, and demographic data including height, weight, body mass index (BMI), and age were described. Mean semen parameters and the proportions of men with suboptimal parameters based on the World Health Organization's fifth edition criteria were also compared based on race. Multivariable regression analysis was conducted incorporating age, BMI, and year of evaluation. Further subanalyses based on BMI were subsequently performed. White men produced greater volumes of semen on average; however, Asian men had higher sperm concentrations and total sperm count. A lower proportion of Asian men compared to white men had semen quality in the suboptimal range for most semen parameters, whereas a higher proportion of white men were found to have azoospermia. Stratification by BMI groups attenuated the observed differences between whites and Asians, yet Asian male semen quality remained higher. Among men evaluated for infertility at a single center, Asians had lower volume but higher sperm conc...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
