The PMHNP has just diagnosed a 21-year-old unmarried man with obsessive-compulsive disorder (OCD). In which one of the following ways do men with OCD differ from women with the disorder?

Choice A reason: Severity does not consistently differ between sexes; men are not uniformly more severe. Choice B reason: Severity is variable and not reliably lower in men. Choice C reason: Spontaneous recovery is rare in OCD and does not differ by sex. Choice D reason: This is correct. Men tend to have an earlier age of onset, often during childhood or adolescence, while women more commonly present in adulthood.
