Thomas Aquinas,
Summa Theologiae — Question 92 - THE PRODUCTION OF THE WOMAN…
“ I answer that, It was necessary for woman to be made, as the Scripture says, as a "helper" to man; not, indeed, as a helpmate in other works, as some say, since man can be more efficiently helped by another man in other works; but as a helper in the work of generation. This can be made clear if we observe the mode of generation carried out in various living things. ”
