What sets GYN-CS® apart from other preventive methods following ceasarean section?


GYN-CS® is a hormone free contraceptive method. It consists of copper tubes on a surgical thread. Due to the slim and flexible design of GYN-CS®, it fits comfortably into every uterus.


GYN-CS® adapts!

The GYN-CS® design allows for a perfect fit and adapts to the changes and movement of the uterus. This significantly increases women’s well being and the quality of life.

GYN-CS® 3 is an excellent contraceptive option for contraceptive protection during the interpregnancy interval and GYN-CS® 10 is effective for 10 years and can be a reversible alternative to sterilization.
