Thinking of men solely as a source of sperm is as goofy as thinking of women as only wombs.

Evolutionarily speaking it makes perfect sense to reduce us to our ability to reproduce and support the offspring. I don’t really think men provide anything women can’t.... except sperm.

As one fond of Dawkins's ideas around the "extended phenotype", I'd argue that the biggest contributors to human procreation in the past several millennia were technological and economical rather than directly biological.
