Low sexual<unk>  alone is not equivalent to<unk>  because of the requirement in<unk>  that the low sexual<unk>  causes marked distress and interpersonal difficulty and because of the requirement that the low<unk>  is not better accounted for by another disorder in the DSM or by a general medical problem. It is therefore difficult to say exactly what causes<unk> . It is easier to describe, instead, some of the causes of low sexual<unk> . In men, though there are theoretically more types of<unk> /low sexual<unk> , typically men are only diagnosed with one of three subtypes. * Lifelong/generalised: The man has little or no<unk>  for sexual stimulation (with a partner or alone) and never had. * Acquired/generalised: The man previously had sexual interest in his present partner, but lacks interest in sexual activity, partnered or solitary. * Acquired/situational: The man was previously sexually interested in his present partner but now lacks sexual interest in this partner but has<unk>  for sexual stimulation (i.e. alone or with someone other than his present partner.) Though it can sometimes be difficult to distinguish between these types, they do not necessarily have the same cause. The cause of lifelong/generalized<unk>  is unknown. In the case of acquired/generalized low sexual<unk> , possible causes include various medical/health problems, psychiatric problems, low levels of testosterone or high levels of prolactin. One theory suggests that sexual<unk>  is controlled by a balance between inhibitory and excitatory factors. This is thought to be expressed via neurotransmitters in selective brain areas. A decrease in sexual<unk>  may therefore be due to an imbalance between neurotransmitters with excitatory activity like dopamine and norepinephrine and neurotransmitters with inhibitory activity, like serotonin. Low sexual<unk>  can also be a side effect of various medications. In the case of acquired/situational<unk> , possible causes include intimacy difficulty, relationship problems, sexual addiction, and chronic illness of the man's partner. The evidence for these is somewhat in question. Some claimed causes of low sexual<unk>  are based on empirical evidence. However, some are based merely on clinical observation. In many cases, the cause of<unk>  is simply unknown. Some factors are believed to be possible causes of<unk>  in women. As with men, various medical problems, psychiatric problems (such as mood disorders), or increased amounts of prolactin can cause<unk> . Other hormones are believed to be involved as well. Additionally, factors such as relationship problems or stress are believed to be possible causes of reduced sexual<unk>  in women. According to one recent study examining the affective responses and attentional capture of sexual stimuli in women with and without<unk> , women with<unk>  do not appear to have a negative association to sexual stimuli, but rather a weaker positive association than women without<unk> .
