Dear Colleagues,

We are honored to announce that The World Congress on Controversies in Obstetrics, Gynecology & Infertility (COGI) will hold its 21st edition in the picturesque city of Guilin, China May 7-10, 2015.

COGI is a unique concept congress which links all fields of obstetrics, gynecology and infertility with their sub-disciplines. Join top opinion leaders for in-depth debates and discussions on the pressing issues of our profession.

We invite young scientists to join us in Guilin and present their work for the “Under 34” competition and enjoy a discount on their registration fees.

We would like to invite you to join us in shaping and bringing to light a provocative program, and to contribute to a successful and invigorating congress.
