The raison d'etre of this website is to provide you with hard scientific information which may help you make informed decisions in your quest for health (so far I have blogged concise summaries of over 1,500 scientific studies and have had three books published).

My research is mainly focused on the effects of cholesterol, saturated fat and statin drugs on health. If you know anyone who is worried about their cholesterol levels and heart disease, or has been told to take statin drugs you could send them a link to this website, and to my statin or cholesterol or heart disease books.

The aim of the study was to evaluate whether the use of statins is associated with the concentration of sex hormones. The study included 237 men, average age 58 years.

the study found:
(a) The total testosterone levels of men taking statins was 9% lower than men not taking statins.
(b) The free testosterone levels of men taking statins was 18% lower than men not taking statins.
(c) The calculated free testosterone levels of men taking statins was 11% lower than men not taking statins.
(d) The bioavailable testosterone levels of men taking statins was 19% lower than men not taking statins.

Medras concluded: "Our study unequivocally confirms that the use of statins is associated with lower levels of: total testosterone, free testosterone, calculated free testosterone and bioavailable testosterone".
