Brief Summary

Our study addresses a previously selected population or by physical activity but not for semen quality semen donor candidates donation program within the clinic. Total physical activity was analyzed according to the universally accepted international physical activity questionnaire (IPAQ) The existence of confounding factors associated She purge age, snuff, weight, BMI, alcohol, drugs, type of sport and associated blood parameters determinations will be made to exercise.

Conditions

Sexual Abstinence

Outcome Measures

Primary Outcomes (1)

• Ascertain the influence of physical activity in sperm quality to candidates for sperm donors in the donation program according to the universally accepted questionnaire International physical activity (IPAQ)

  Semen parameters will be evaluated according to WHO criteria blinded on clinical and data analyst. International Physical Activity Questionnaire (IPAQ) offers before sperm donation quantifying the activity "walk", "activities of moderate intensity" and "vigorous intensity activities" assigned to each activity about energy requirements defined in METs, being multiples of the rate of metabolic rate equivalent to kilocalories for a 60 kg. The median and interquartile range (between Q1 and Q3) is calculated for walking (W), activities of moderate intensity (M), activities of vigorous intensity (V) and a combined result of total physical activity. All results must be expressed as continuous METminutos / week.

Secondary Outcomes (1)

• Existence of confounding factors associated with physical activity

  2 years

Study Arms (3)

IPAQ HIgh

Excessive physical activity:IPAQ quantifying the activity physical according vigorous intensity activities at least 3 days per week adding a minimum total physical activity of at least 1500MET-minutes / week or 7 or more days any combination of walking, moderate intensity or vigorous intensity activities a total minimum of physical activity of at least 3,000 MET-minutes / week

Other: International Physical Activity Questionnaire (IPAQ)

IPAQ Moderate

Ideal Physical activity: IPAQ quantifying the activity physical according 3 days or more of vigorous intensity physical activity at least 20 minutes per day or 5 or more days of moderate intensity and / or walk at least 30 minutes per day or 5 or more days of any combination of walking, moderate-intensity activity and activity vigorous intensity for a total minimum of physical activity of at least 600 MET-minutes / week.

Other: International Physical Activity Questionnaire (IPAQ)

IPAQ Low

IPAQ quantifying the activity physical according Insufficient physical activity: Individuals who can not put on the criteria of the above categories.

Other: International Physical Activity Questionnaire (IPAQ)

Interventions

International Physical Activity Questionnaire (IPAQ) OTHER

all candidates for sperm donors clinic IVI IVI Bilbao and Valencia were will provide the international physical activity questionnaire (IPAQ) attached to analyze the total physical activity. This will be self-completed questionnaire beforeSperm donation. (Appendix 1) Age, snuff, weight, BMI, alcohol, drug use and the type of sport that practices will be analyzed: Additionally a tab for each donor collecting the existence of associated factors be drawn. (Appendix 2)

IPAQ HIgh; IPAQ Low; IPAQ Moderate
