Well, we learned sometime in the Cell saga that 18 started out as a human and was modified to be a cyborg android. This also means that Marron might be the first human-cyborg hybrid offspring in existence, though not the only one. Android 17 was revealed to also have had a child in Dragon Ball Super.

Is Android 17 still an android?

Android 17 is ultimately killed when Semi-Perfect Cell self-destructs on King Kai’s planet. 17’s life is restored after the Z Fighters use the Dragon Balls to revive those who died as a result of Cell’s campaign. A second wish made to Shenron by Krillin removes the Android Bombs within Lapis and Lazuli’s bodies.

How old were Android 17 and 18?

Assuming their number designation could be a hint to their approximate age when they were introduced, as they were kidnapped as children, this would make both Android 17 and 18 in their late 20’s or early 30’s by the end of the Dragon Ball Super anime.
