Yên is also used as a masculine name in Vietnamese, alongside An. However, Yên is more common for females. So, I think that the "Gender" of this name should be changed from "Feminine" to "Feminine & Masculine".Sources: https://www.names.org/n/yen/about https://forebears.io/forenames/yen
Yen is the name of Japan's currency in English, not Japanese. In Japan, the pronunciation is En. So, someone with this name would not be laughed at in Japan because the pronunciation is not the same.

Can also be found being used in China, with the meaning of "one", not the number but the "one" as in the 'one and only'.
