The TVTropes Trope Finder is where you can come to ask questions like "Do we have this one?" and "What's the trope about...?" Trying to rediscover a long lost show or other medium but need a little help? Head to Media Finder and try your luck there. Want to propose a new trope? You should be over at You Know, That Thing Where.
Viewer Gender Confusion could work as an example of intersex, but that's a guess.
Honestly, "Ambiguously Queer" would be the better thing to start looking for.

Depends on what exactly you're meaning by "implied to be intersex":
Ambiguous Gender (aka Ambiguous Sex) applies if, say, it's hinted someone may or may not be a hermaphrodite.
Ambiguous Gender Identity if the work keeps it ambiguous about where on the spectrum the character identifies - a classic example is leaving it ambiguous whether a character is a cis-male crossdresser or Drag Queen, trans-female, or somewhere between.
The two can overlap in particularly complicated situations as well- say, a Fair Folk character intentionally goes out of their way to invoke Otherworldly and Sexually Ambiguous by keeping people wondering if they're a masculine cis-female Lad-ette, a camp queen, or a flamboyant true hermaphrodite.

^ The narrative implies a character is intersex, but it's vaguely done.
If a character is implied to be intersex, do we have a trope for that? The closest I can think of is either Ambiguous Gender or Ambiguous Gender Identity, but I don't know which would fit best.
