The Major Sexual Fluid (Mani)
If one were to intentionally cause the ejaculation of the major sexual fluid, semen (mani), during the daytime of a fast, then that fast would be invalid. The person would have to make up that fast and pay a penalty (kaffara) which would be either fasting sixty days consecutively, feeding sixty poor Muslims, or freeing a Muslim slave. One kaffara would be done for every day that was broken (Mukhtasar Khalil).
The Minor Sexual Fluid (Madhi)
The emission of pre-seminal fluid (madhi) only requires washing of the entire penis, and wudu not a full shower (ghusl). It also invalidates the fast if the person did something intentionally to cause it to come out. If one knows that by looking, thinking or touching that madhi will exit and it does, then the fast is broken and must be made up with one day, not the kaffara mentioned above.
