Why happens to people who swim in the waters of the fountain Salmacis?

In Greek mythology, those who swim in the waters of the fountain Salmacis are transformed into a state of androgyny. The fountain is associated with the nymph Salmacis, who desired Hermaphroditus, the son of Hermes and Aphrodite. When Hermaphroditus entered the water, Salmacis embraced him, and their bodies merged, resulting in a dual-gendered being. This transformation symbolizes the blending of male and female traits.
