I'm not sure if this is a mistake or a neologism, and in the latter case it would be very little disseminated (is there any moderately serious text that supports it? I did a quick search in books or newspapers and it didn't even appear) so it would be interesting to at least know the origin, how such a strange term was constructed. It could be for 'manliness', which has very varied definitions, from a covert machismo to a humanist perspective better integrated with rationalism, through medical voices (relating to hormonal treatments) or obsessive sexual fixations with the shoulders (128527; ); And perhaps it is because of this polysemic multiplicity that a variant such as 'manhood' has been created, which will continue to be a capricious construction but then it is almost justified. See femichism.
