Comparing engineering-only numbers to all-graduates numbers is not useful. All-graduates numbers are strongly affected by the very low number of jobs available for most humanities and (to a lesser extent) social sciences majors. This article doesn't have numbers on men leaving the engineering workforce, but this one [1] does. The numbers aren't exactly comparable, since it doesn't count people that never even start working in engineering, and is from 2009. It claims about 10% of men leave engineering by age 30, compared to around 25% of women.
