Table 1 Semen parameters before and after 3 months according to each treatment group

From: Comparison of the effect of a combination of eight micronutrients versus a standard mono preparation on sperm parameters

  1. Data are presented as mean ± standard deviations
  2. * p value < 0.001 as compared to basal as determined with the paired Student’s T test
  3. ** p value < 0.05 as compared to mono treatment as determined with the non paired Student’s T test
  4. a Absolute change for each variable and case was calculated subtracting third month value minus basal one
  5. b relative change is the percent expression of each calculated absolute value
