Dem Wunsch nach verlän gerter Wirkungsdauer entsprach en dann Kristallmischsuspension en verschiedener Korngröße aus Östradiolmonobenzoat + Progesteron, deren Anwendung sich auf klinische Untersuchungen besch ränkte (83). Ölgelöste Depotpräparate mit Östradiolbenzoat oder -valerat + 17-hydroxyprogesteroncaproat wurden ab 1955 in die Therapie eingeführt (45.46).}}
