Radial Velocity surveys have revealed up to now about 100 extra-solar planets (Msini<10MJup) and a few multi-planetary systems. The discovered planets present a wide variety of orbital elements and masses which are raising many problems and questions regarding the processes involved in their formation. But the analysis of the distributions of orbital elements like the period and eccentricity distributions is already giving some constraints on the formation of the planetary systems. Furthermore the study of the planet host stars has revealed the impressive role of the stellar metallicity on the giant planet formation. In this talk we will review the current status of the research on this subject.
