Definitions for "jeopardize"
To expose to loss or injury; to risk.
An ED patient should not jeopardize the relationship with his partner. Partners of men suffering from erectile dysfunction can often feel they are part of the cause -- by being no longer desirable or attractive. This is a common reaction. Even worse, a woman may begin to fear her husband is having an affair ! If the man fears ED is a sign of failure on his part, a partner can risk alienating or embarrassing him further. If not properly dealt with, a relationship or marriage can come to an end over these unfounded fears and the awkwardness of the situation. The solution lies in effective communication between partners.
put at risk; "I will stake my good reputation for this"
pose a threat to; present a danger to; "The pollution is endangering the crops"
