To observe the effect of the aqueous extract of hypocotyls of the plant Lepidium meyenii (Maca) on spermatogenic damage induced by the organophosphate insecticide malathion in mice.
Data obtained from the experimental groups are presented as relative values with respect to values obtained in the control group of animals killed on day 0 and are expressed as mean ± SEM in the tables. To calculate relative values, the mean control value at each stage was defined as 1.
Data from each stage in each treatment were compared with the corresponding control value. When variances were homogeneous, one-way analysis of variance was used in the statistical assessment of these comparisons. In this case, the Scheffee test was used to detect differences between pairs of means. When data from a given stage was compared between the malathion group and the malathion plus Maca group, the t-test was used. P < 0.05 was considered statistically significant.
