用進廢退是指生物體的器官經常使用就會變得發達,而不經常使用就會逐漸退化。就像大腦,越是勤思考勤運用,便越靈活;而越是懶惰不動腦,大腦便會像生鏽的鏈條,難以正常運轉。
用進廢退這個觀點最早是由法國生物學家拉馬克提出,他在《動物的哲學》中系統地闡述了他的進化學說(被後人稱為“拉馬克學說”),提出了兩個法則:一個是用進廢退;一個是獲得性遺傳。並認為這兩者既是變異產生的原因,又是適應形成的過程。他提出物種是可以變化的,種的穩定性只有相對意義。生物進化的原因是環境條件對生物機體的直接影響。認為生物在新環境的直接影響下,習性改變、某些經常使用的器官發達增大,不經常使用的器官逐漸退化。並認為適應是生物進化的主要過程。
Jean-Baptiste Lamarck (1774 – 1829) was a French botanist who proposed two ideas that had great impact in the theory of evolution.
The first idea of use and disuse is only the first part of Lamarck’s revolutionary thought. It is referred to as the 'First Law' of his publication, Philosophie Zoologique. . The use or disuse theory explains that the parts of an organism that the organism uses most will undergo hypertrophy and will become more developed. Hypertrophy is the growth of a specific organ or tissue. So by this idea, the more an organism uses a part of its body, the larger and more developed that part will become. The parts of the organism that are not used as much undergo atrophy and begin to degrade from lack of use. This means that the part of the organism will get decrease in size due to the lack of use for that particular part of the organism. This is the beginning of the idea of inheritance of acquired traits.

女性的性功能也會“用進廢退”
有的男士很困惑地發現,生過孩子的太太突然對 房事興趣索然,大部分時間都投入到照顧孩子上了, “自己連三分之一的愛都得不到”。有些夫妻擔心 性愛遭遇夜半孩子的哭聲,乾脆過起了無性生活。 很多中年夫妻索性分床而睡,認為距離產生美, 結果是“距離有了,美沒了”。





懷孕、哺乳期間,女性體內的激素水平發生改變, “性趣”降低,再加上照料孩子辛苦,很多夫妻性愛 不和諧,都是從生育孩子開始的。這時,丈夫要主動 和妻子交流感情,共同承擔責任,畢竟性生活的重要 組成部分是情感的交融。
