Reproduction

Reproduction or procreation is a trait common among many species of animals and is a trait of humans.

In Smurfs Media
In mainstream Smurfs media, Smurf reproduction is non-physical, as all baby Smurfs are brought to the Smurf Village from an unknown location on the night of a blue moon by stork.

Empath: The Luckiest Smurf stories
However, in the EMPATH: The Luckiest Smurf story series, Smurfs can reproduce physically, since the Smurfs in that series are by nature a two-gendered race, with both genders having reproductive organs similar to that of humans. The normal gestation time of a Smurf from conception to birth during a pregnancy is usually around seven to nine months, after which they are delivered through the birth canal and nursed for about ten years until they can develop the appetite for solid food.

Psyche reproduction is mostly handled by the Psyche Master, as they are created from Smurf essence made from the Psyche Master's beard, and are put into gestation chambers for the same period of time as a Smurf pregnancy. However, the Psyches are given some level of accelerated aging during their gestation period that they will emerge from their gestation chambers as young Psychelian children.
