German words: still used by Japanese obstetrics and gynecology doctors.

BACKGROUND: German used to be frequently employed in Japanese obstetric and gynecologic (OBGYN) practice; however, it is now less frequently used. Description and analysis of this situation may shed some light on the change of OBGYN practice and education in Japan, which may at least partly hold true to counties other than Japan.

METHODS: Three eras were classified according to the relationship between German and Japanese OBGYN, with each era characterized. Frequently used German words in Japanese OBGYN practice were described as examples.

RESULTS: German words have become less frequently used with each successive generation.

CONCLUSIONS: Even though English may suffice in practical OBGYN practice, German usage will still be passed on to these new generations.
