The title “when to go to hospital in labor” can be translated into German as:

**Wann sollte man bei Wehen ins Krankenhaus gehen**

– **Wann** = when
– **sollte man … gehen** = should one go
– **bei Wehen** = in labor (literally “with contractions”; “Wehen” is the standard medical term for labor contractions in German[2])
– **ins Krankenhaus** = to the hospital (“Krankenhaus” is standard in Germany; “Spital” is used in Switzerland and Austria[2])

This phrasing is clear, medically accurate, and commonly used in German-speaking healthcare contexts. Alternative, slightly more formal options include:

– **Wann sollte man während der Wehen ins Krankenhaus gehen**
– **Wann ins Krankenhaus bei Geburtswehen**

All versions preserve the meaning and are appropriate for medical or informational contexts.
