The man in his 30s is being prosecuted for gross rape and two cases of sexual assault. One of the assaults is considered gross.
The women are in their 80-90s and are considered to have been in a dependent position.
The suspicions concern serious offenses against elderly vulnerable individuals, said plaintiff assistant Emily Töyrä to SVT earlier.
The man was initially investigated for crimes against four women, but one of the women has chosen not to participate in the investigation.
The man denies the crimes.
