男女性功能障礙-新術語體系 詳解比較 當然，為了對這兩種主要的性功能障礙——“膨脹問題”和“性高潮問題”有一個比較清晰的理解，這個新近提出的男女性功能障礙的總體概要可以進一步分類。膨脹(tumescence)，即男女性器官充血，是性喚起的表現指征，那麼，沒有充血就預示著這個個體還未準備好開始性交的時候。在女性，表現為缺乏陰道潤滑；而在男性，則沒有陰莖勃起。性高潮(orgasm)，即表現為兩性一系列由強至弱的肌肉痙攣性收縮所造成的性興奮的巔峰狀態。在某些病例，個體不能適時地達到令他或她滿意的巔峰狀態，還有一些人則根本不能達到性高潮巔峰狀態。 Female and Male Sexual Dysfunctions - A New Terminology Detailed comparison This new general overview  of female and male dysfunctions can, of course, be differentiated further in order to create a clearer understanding of the two major problems - "Problems of Tumescence" and "Problems of Orgasm". Tumescence, i.e. the engorgement with blood of the female and male sex organs is the manifestation of physical arousal, and its absence indicates that the individual is not ready to begin intercourse. In females, there is a lack of vaginal lubrication, and in males, there is a lack of penile erection. Orgasm, i.e. the climax of sexual excitement manifests itself in both sexes in a series of sudden muscular spasms of decreasing intensity. In some cases an individual is unable to time this climax to his or her or mutual satisfaction, and in some other cases is unable to reach a climax at all.
