blood test
muscle strength
Hand-grip strength will be measured by a quantitative handgrip dynamometer in the dominant arm. Mean of three consecutive measurements will be used.
Lean mass

sexual function
Psychosexual daily questionnaire for 7 consecutive days will be used. The questionnaire covers three different domains: 1) sexual desire, enjoyment, and performance; 2) sexual activity score; and 3) mood. Sexual desire (question 1) and sexual enjoyment (question 2) will be rated on a 7-point Likert-type scale from 0 to 7, with 0 indicating none and 7 indicating very high. Sexual performance will be assessed by % full erection and satisfaction with erection (questions 5 and 6). Sexual activity (question 4) will be assessed using a checklist format. The value will be recorded as 0 (none) or 1 (any) for analysis. Higher score indicates higher activity; maximum score on this item is 12. Each mood parameter (question 3) will also be assessed on the 7-point Likert scale.
