Why does my cat twitch and run? My 7 year old female cat has suddenly started twitching her back, running around, stops, grooms herself, and starts running again. I have her on a flea treatment and my other two cats don't do this at all. She only calms down if I pet her or she gets in her basket.
Psychological Causes. The most common causes of low libido in women are not due to physical or biological causes. Psychological causes like poor body image, low self-esteem, depression, stress and physical or sexual abuse are among the top reasons why women have low sex drive.
Testosterone plays a key role in libido (sex drive) in both men and women. Men may experience some decline in sex drive as they age. However, someone with low T will likely experience a more drastic drop in his desire to have sex. Low T can also decrease the sex drive in women, along with other factors, such as other hormonal and mood changes.
