After the detection of yeasts in 1839, German speaking mycology was first performed in obstetrics to find out the source of neonatal thrush. The authors are Berg (1846), Mayer (1862), Martin (1856), Winckel (1866), Haussmann (1870), Kehrer (1883), Epstein (1924), Rüther, Rieth and Koch (1958), Malicke (1963), Blaschke-Hellmessen (1968) and Schnell (1981) and others. In the gynecological field yeasts, vaginal mycoses and therapeutic problems had been investigated by the gynecologists Döderlein (1892), Spitzbart (1960), Lachenicht and Potel (1971), Neumann and Kaben (1971), Müller and Nold (1981) and Mendling (1987, 1995). Many gynecological papers, however, had also been written by dermatologists and microbiologists.
