性-人类性的基本层面
Sex - Basic Aspects of Human Sexuality

性激素的功能：雄激素

雄激素过多？
不仅睾丸激素的增加常常导致性活动增加、甚至强制的性活动，而且在某些情形下将某些性体验（sexual scripts）付诸行动时，更是如此。例如：意外的机遇、离婚后忽然如释重负而“从事恋爱交往”、在度假期间、个人挫折、坚持自己权利的愿望、修补已经损坏的自我形象的需要、荒淫无度时的财政压力等等。另一方面，无论社会环境怎样，睾丸激素水平的骤然下降通常会减少性活动。
 

The Role of Hormones: Testosterone

Too much testosterone?
Increased or even compulsive sexual activity is very often caused not by an increase in testosterone production, but rather by the acting out of certain sexual scripts in certain situations. Examples: Unexpected opportunity, sudden freedom "to play the field" after a divorce or during vacations, personal frustration, a wish to assert oneself or the need to repair a damaged self-image, financial pressure in prostitution etc. On the other hand, it is true that a drastic lowering of the testosterone level (e.g. as a result of taking certain medications) usually reduces sexual activity regardless of social circumstances.
