Spermula is a French erotic fantasy film from 1976 director by Charles Matton starring Canadian super model Dayle Haddon.

There were two versions of the film at the time of the original release, one in French and one in English. The different versions have different plots and dialogue.

The French version originally was released with the title L'amour est un fleuve en Russie and is less of a space opera than is the English-language version Spermula which leans more towards science fiction.
