Semen quality of Yankasa rams

Tropical Animal Health and Production, 1982
Presents results of a study carried out to determine the ejaculate characteristics of Yankasa rams in Nigeria. Three rams of proven fertility from the breeding herd at shika, of average age of 29 months were investigated. Ejaculates collected during the wet season had higher volume, pH, sperm motility and percentage of normal sperms than those ...

Impact of supplementation of semen extender with antioxidants on quality of cooled or cryopreserved Marwari stallion spermatozoa

Indian Journal of Animal Sciences, 2021
The aim of the present study was to evaluate the effects of supplementation of semen extender with two antioxidants namely Ascorbic acid (AA @ 0.9 g/L), Glutathione (GSH @ 2.5 mM), and combination of both (AA @ 0.9 g/L + GSH @ 2.5 mM) either in alone or ...

Presence of human papillomavirus in semen in relation to semen quality [PDF]

Human Reproduction, 2016
Is the presence of human papillomavirus (HPV) in semen associated with impairment of semen quality?In a large cohort of males seeking fertility evaluation, no associations were observed between seminal HPV presence and semen parameters.HPV is commonly detected in semen samples.

Establishing an Apheresis Medicine Program in a Resource‐Constrained Setting: A 5‐Year Experience From Lagos, Nigeria

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Establishing a comprehensive apheresis medicine program in a resource‐constrained setting presents significant structural, financial, and logistical challenges. Despite the growing clinical importance of apheresis services globally, published experience from sub‐Saharan Africa remains sparse.

Cr (VI)-induced ribosomal DNA copy number variation is associated with semen quality impairment: Evidence from human to animal study

Ecotoxicology and Environmental Safety
Objectives: This study aimed to analyze the possible role of rDNA copy number variation in the association between hexavalent chromium [Cr (VI)] exposure and semen quality in semen donors and further confirm this association in mice.

Forecasting the Dialysis Burden in Japan: Validation‐Based Projections of Prevalence and Incidence Through 2050

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Japan has one of the highest dialysis prevalence rates worldwide and a shrinking, aging population. Whether dialysis burden has entered a sustained post‐peak phase or whether recent declines partly reflect pandemic‐related disruptions remains uncertain.

Integrative Transcriptomic and Genomic Analysis Reveals the Regulatory Mechanisms Underlying Semen Quality Stability in Ganders

Poultry Science
Semen quality significantly affects the reproductive performance of ganders. As seasonal breeders, ganders typically experience a decline in semen quality over the breeding season; however, the mechanisms regulating semen quality stability during this ...

Reciprocal control of viral infection and phosphoinositide dynamics

FEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Variations in Semen Quality and the Relationship of Semen Quality to Fertility in Turkeys ,

Poultry Science, 1968
Abstract INTRODUCTION IT would be of great value if males could be selected on the basis of semen quality prior to the breeding season. The thought of such a relationship is particularly intriguing in turkey management where considerable artificial insemination is practiced and where, in many instances, fertility levels are not satisfactory. Little

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative
