Inhibited desire, or loss of libido, refers to a decrease in desire for, or interest in sexual activity. Reduced libido can result from physical or psychological factors. It has been associated with low levels of the hormone testosterone. It also may be caused by psychological problems, such as anxiety and depression; medical illnesses, such as diabetes and high blood pressure; certain medications, including some antidepressants; and relationship difficulties. buy cheap viagra online now
