Improvement of semen quality by nocturnal scrotal cooling and moderate behavioural change to reduce genital heat stress in men with oligoasthenoteratozoospermia

The effects of green tea (Camellia sinensis) extract on mouse semen quality after scrotal heat stress

The objective of this study was to investigate whether or not the adverse effects of heat on sperm quality could be prevented by green tea extract (GTE) administration. Ninety adult male mice were randomly divided to two groups. The scrotum of each animal in the first group was immersed once for 20 min in a water bath maintained at 42 oC (heat group, H) and the second group (control group, C) w...

Improvement of Semen Quality in Holstein Bulls during Heat Stress by Dietary Supplementation of Omega-3 Fatty Acids

Improvement of Semen Quality in Holstein Bulls during Heat Stress by Supplementing Omega-3 Fatty Acids

The aim of current study was to investigate the changes in the quality parameters of Holstein bull semen during the heat stress and the effect of feeding a source of omega-3 fatty acids in this period. Samples were obtained from 19 Holstein bulls during the expected time of heat stress in Iran (June to September 2009). Control group (n=10) were fed a standard concentrate feed while treatment gr...

Presentation of an Operational Program to Reduce vulnerability of outdoor workers to to heat stress and climate change

Background: Outdoor workers are vulnerable to heat stress and climate change due to their occupational and environmental conditions. Short-term exposure to extreme heat (acute exposure) can lead to rise the core body temperature, which it may directly cause heat related illnesses such as mild rash, cramps, heat exhaustion and heat stroke. It is reported that long-term chronic exposure to heat l...
