A quote from Aubrey Burl’s ‘Rites of the Gods’:
Up until the eighteenth century, a ‘barren wife’ might visit the circle during the night “in the hope that by baring her breasts and touching the Kingstone with them” she would be made pregnant.
Does this mean you actually become pregnant as a result of touching the stone – what Burl surely implies? He doesn’t specify his source. You’d imagine it more likely that the stone would make you more fertile and so more likely to get pregnant via the usual method. But maybe I’d never really thought about this (not uncommon?) idea before: maybe it is the former that was believed? Especially with the stone being male – the King in fact.
