Study: Poor diet can impact genetic causes of male infertility
The impact of diet on fertility
This research focused on men and the reasons they may have difficulty fathering a child
Turns out a poor diet worsens genetic causes of male infertility
University of Melbourne doctors say a high-fat, high-sugar diet worsens sperm quality and fertility outcomes
The finding helps explain why men with similar genetic mutations experience different levels of fertility impairment.
Study authors say this proves environmental and lifestyle choices are a major factor in infertility
Tailored exercise program can help reduce time in AFib
Most patients with atrial fibrillation take medication to limit the impact of the heart rhythm disorder
But a new Norwegian University study shows a regular exercise routine also carries a huge impact
A one-year tailored exercise program reduced time in a-fib compared with medication alone

Doctors started short-term supervised exercise routines, followed by a long-term prescription for at-home activity
Those who stuck to the exercise program for one year experienced meaningful benefits, including reduced chaotic and irregular heartbeats
Statins can help lower risk of dementia
A popular anti-cholesterol medication appears to protect the mind
Statins reduce the risk for dementia, according to a study presented at the European Society of Cardiology
The decade-long study followed people with type 2 diabetes who got a statin prescription
Type 2 diabetes is associated with high cholesterol and an enhanced threat for cognitive decline and dementia.
The initiation of statins was associated with a 15 percent lower risk for dementia
The earlier patients started taking the drugs, the better memory protection
With no approved dementia treatment, doctors say prevention is an urgent priority
