Using the interview method, three sexologists examined over a period of 36 years the sexual development and life of 2425 gynecological patients who were sent to Frant. Láznĕ (Franzensbad) for post-treatment of conditions following gynecological inflammations or surgery. They had all been married at least one year and when interviewed were 20-40 years old. After their division into individual decades of birth between 1911 and 1970 it was ascertained that the percentage of coitally orgastic women continuously increased from 31% to 80%. This was accompanied by a distinct increase of coital activity. On the basis of results of new sociological studies the authors try to explain the increase of sexual satisfaction mainly through changes in the course of sexual life of women. These were caused through changes of social milieu not only after the second world war but also in the course of the whole twentieth century. The authors are of the opinion that the sexual satisfaction in women will remain due to biological differences always somewhat lower than in men.
