In some people, Escitalopram does cause sexual dysfunction
. In your case, if it has not caused any dysfunction yet then you probably do not need to worry about it. Also, the severity of dysfunction may vary. If the dysfunction is mild, then you may make an informed choice that the benefit of the medicine is more important than the sexual dysfunction. If the dysfunction is significant, then you should discuss this with your physician and consider alternative medicines.
Escitalopram is NOT known to decrease fertility
in the long term. Its side-effects are on sexual performance and the sexual experience, but no direct adverse effect on fertility.
