Massey University is conducting a study investigating wellness, lifestyle and diet (The Well-LaD Study) in New Zealand men aged 40-70 years, with a focus on erectile dysfunction as a marker for subclinical cardiovascular disease.
Our aim is to determine the prevalence and severity of erectile dysfunction in New Zealand men and its relationship to dietary and lifestyle factors, highlighting areas for effective intervention. Vitamin D is one potential area for intervention that could have dramatic effects on male sexual function with the added benefit of reduced risk and/or slowed progression of cardiovascular disease.
Men in the Palmerston North region are being recruited for this study.

The positive findings of the Surya Study have attracted considerable attention around the world.
The Kalya Study explored the vitamin D status, bone health and muscle strength of young women (20-29 years) of European, Chinese, Korean and South Asian ethnicities living in Auckland.
