Valuation of Variable Dose of Docosahexanoic Acid for the Improvement of the Parameters of Male Fertility (DHA)

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT02889341
Recruitment Status : Completed
First Posted : September 5, 2016
Last Update Posted : August 2, 2017
Information provided by (Responsible Party):
IVI Sevilla

Brief Summary:
Sperm parameters will be examined before DHA (DHA=Docosahexanoic Acid) consumption, after one months and after 2 months taken Docosahexanoic Acid or placebo.

Condition or disease Intervention/treatment Phase
Male Infertility Dietary Supplement: DHA Other: Placebo Not Applicable

Detailed Description:
Prospective, randomized, double blind, placebo-controlled intervention study within individuals. Assisted reproduction unit and academic research laboratory. One hundred an eighty human semen samples from 60 infertile patients of IVI Sevilla clinic were finally included. Assessment of oxidative stress, apoptosis, lipid peroxidation, mitochondrial membrane potential, DNA fragmentation and standard sperm parameters before and after supplementation with different DHA doses (0.5, 1 and 2 g) or placebo for 1 and 3 months.
