What are the things that invalidate ghusl?

Ghusl is not invalidated by what invalidates wudu, but rather by the occurrence of what necessitates it, such as sexual intercourse and the emission of semen. So, if something that necessitates ghusl occurs during ghusl or after it, ghusl becomes invalid and must be repeated. Among the things that invalidate ghusl is renouncing the intention during ghusl. As for renouncing the intention after completing ghusl, it does not affect it. Ghusl is like wudu in this regard.
