The Effect of Supplementation with Some Essential Oils on the Mobility and the Vitality of Human Sperm

Figure 3

The in vitro effect of EOs on the proportion of spermatozoa with a vitality ≥ 58%. We prepared the dilution of EOs in a sterile solution of agar at 0.2% (w / v) for a range concentration of 10⁻¹, 10⁻², 10⁻³, and 10⁻⁹. The motility percentage of each aliquot was measured immediately after the supplementation with the HE (t = 5 min) and 10 minutes later (t = 10 min). The data are expressed as mean ± standard deviation (n = 5). () indicates “p” values: significant (p <0.05); highly significant (p <0.01); highly significant (p <0.001).
