Fertility Blessing

The Fertility Blessing is one that appears in some Smurfs fanfiction series.

Empath: The Luckiest Smurf stories
In the EMPATH: The Luckiest Smurf story series, the Fertility Blessing is usually given by Mother Nature to creatures that can't reproduce through physical and/or sexual means, such as elves and pixies. It is also given to Smurfs at the time she deems appropriate for them to have children.

Hero: The Guardian Smurf stories
Though it appears without a name, the Fertility Blessing is given a few times by Mother Nature to Hero and his two wives in the HERO: The Guardian Smurf story series, since although the Smurfs in that series could have sex, they couldn't produce children of their own through sexual means. This blessing allows both Wonder and Smurfette to have children that are "fathered" by Hero that require nine months of gestation before they are ready to be born.
