Detailed Description
Recruitment of healthy volunteers through registers (Clinical Investigation Centers) and advertisements.
Recruitment of haemophilic patients during a routine visit at the haemophilia centre.
Information of the subjects that the study requires a BMD measure for all and a blood sampling for patients only.
After inclusion and exclusion criteria have been checked, the subject can sign the consent.
For all subjects, an appointment will be made for BMD measure. For patients and controls: BMD will be measured by Dual Energy X-ray Absorptiometry (DXA) technology, on femoral and lumbar spine (L2-L4) sites.
For patients, fVIII/fIX activity and antigen, thrombin generation potential and plasmatic markers of bone remodelling will be measured centrally.

Eligibility Criteria
Ages Eligible for Study
Accepts Healthy Volunteers
Description
Inclusion Criteria:
Healthy Volunteers :
- Healthy men aged between 20 to 60 years old
