Official Title: Effect of Dietary DHA Supplementation on Sperm Quality.

Further study details as provided by Instituto Valenciano de Infertilidad, IVI VALENCIA:

Primary Outcome Measures:
  • sperm concentration [ Time Frame: 5 weeks ]
    million of spermatozoa per milimitre

  • Sperm motility [ Time Frame: 5 weeks ]
    Percentage of motile sperm.

  • Sperm morphology [ Time Frame: 5 weeks ]
    Percentage of sperm with normal morphology

  • Total capacity antioxidant [ Time Frame: 5 weeks ]
    Total antioxidant capacity (TAC)is a colorimetric assay that measure the combined antioxidant activities of all its non enzymatic constituents in seminal plasma.

  • Sperm DNA damage. [ Time Frame: 5 weeks ]
    DNA fragmentation analysis was evaluated by TUNEL test and measured by flow cytometry

  • Fatty acids measure. [ Time Frame: 5 weeks ]
    Fatty acid analysis in seminal plasma and spermatozoa were evaluated by gas chromatography.The percentage of each fatty acid class was expressed as percentage of total fatty acids.

Secondary Outcome Measures:
  • Sperm in ejaculate [ Time Frame: 5 weeks ]
    Million of spermatozoa in eyaculate.

  • Volume of ejaculate. [ Time Frame: 5 weeks ]
    Eyaculated milliliters.

  • Sperm viability [ Time Frame: 5 weeks ]
    Porcentage of sperm whitout membrane damage
