Egypt remained neutral in World War II, but under heavy pressure from Lampson, Farouk broke diplomatic relations with Germany in September 1939. On 7 April 1940, Queen Farida gave birth to a second daughter, Princess Fawzia, which greatly upset Farouk; After Fawzia's birth, Farouk's marriage started to become strained as he wanted a son. In Egypt, sons are much more valued than daughters, and Farouk was becoming widely viewed as lacking in masculinity due to the absence of a son. Farouk consulted various doctors, whom advised him to eat foods that were felt to increase the sex drive, and Farouk became something of a bulimic, eating excessively and later becoming overweight. Suspicions that Queen Farida was having an affair with an aristocrat, Wahid Yussri, imposed strains on the marriage as Farouk could not stand the idea of being cuckolded.
