calculate likelihood based on logit regression

Hi,

I just ran the following logit regression. But can
anyone tell me how to calculate how much more likely
males (Male=1) could show such symptom than
females(Male=0)? I know it must be simple to get once
I have the coefficients, but I just don't recall.
Thank you very much!

Call:
glm(formula = Symptoms ~ 1 + Male, family =
binomial(link = logit), 
    data = HA)
Deviance Residuals: 
       Min          1Q      Median          3Q        
Max  
-6.038e+03  -2.067e-06   0.000e+00   0.000e+00  
6.720e+03  
Coefficients:
                      Estimate Std. Error    z value
Pr(>|z|)    
(Intercept)          5.711e+00  8.466e-02  6.746e+01  
<2e-16 ***
Male        -6.493e+00  8.540e-02 -7.603e+01   <2e-16
***


Best,
Ed

I think males are z times more likely to show such
symptom, where:

z=(1+exp(6.493-5.711))/(1+exp(-5.711))

Is this right? Thanks!
