Which symptom is typically associated with Couvade syndrome?

Couvade syndrome, also known as sympathetic pregnancy, refers to the phenomenon where a partner experiences pregnancy-like symptoms during their significant other's pregnancy. Among the various symptoms that can occur, nausea and vomiting are particularly common and are often considered characteristic of Couvade syndrome. These symptoms may mimic those typically experienced by women during the early stages of pregnancy due to hormonal changes or psychological factors related to the pregnancy experience.

While the other listed options may occur in different circumstances, they are not specifically associated with Couvade syndrome in the same way that nausea and vomiting are. Severe headaches, shortness of breath, and fatigue can result from various causes but are not primarily recognized as symptoms directly linked to this syndrome. Nausea and vomiting stand out as the most defining symptom for individuals experiencing Couvade syndrome.
