In the setting, boys cannot get pregnant, similar to a kangaroo father. Between husband and wife, the woman "gives birth" to a "egg"-sized "seed" from her belly button when she is pregnant for one month. It is planted in the man's belly button and grows for nine months, and then is born from the man's belly button.

After the "seeds" move in, an umbilical cord that provides nutrients will be produced so that the seeds can grow healthily inside.
