Prozac and libido?

Prozac can affect each person's libido differently, ranging from significant and noticeable change to no change at all. However the general trend is that rather than sparking spontaneous sexual escapades, Prozac has been associated with a decreased libido, difficulty in reaching orgasm, and for some men, difficulty maintaining erections. Between feast and famine, the leaning would be toward famine. Selective serotonin reuptake inhibitors (SSRIs), the class of drugs to which Prozac belongs, often do cause sexual complications. But it doesn't have to be that way.
