Royan International Twin Congress (Reproductive Biomedicine and Stem Cells Biology & Technology) has demonstrated to be one of the most successful scientific gatherings in Iran and the Middle East since 2000. During these twenty-five years of active involvement in sharing and exchanging scientific knowledge and expertise with renowned institutes and scientists, the Royan Congress has helped to form collaborative scientific projects and exchanges.

Following the successful experience of the 26^th Royan International Congress (2025), the Royan Congress intends to hold its 27^th Congress. In the past 6 years and since the COVID 19 outbreak in 2020,  Royan Congress has been held in virtual and hybrid modes, respectively. Once again, the Scientific and Executive Board of Directors decided to hold the 26^th Royan International Congress in an in-person mode that combines face-to-face sessions with some invited speakers who will join the congress virtually.

The 27^th Royan International Congress on Reproductive Biomedicine & the 22^nd Royan International Congress on Stem Cell Biology and Technology (2-4 September 2026), and the 21^st Royan Seminar on Nursing & Midwifery (2-3 September 2026) will take place this year.

This year, the main objective of the Royan International Hybrid Congress is to preserve and enhance connections among researchers and practitioners from all over the world despite the face to face challenges. The Hybrid Congress will cover main topics through highly scientific & extremely innovative online sessions.

We have the pleasure of extending our sincere welcome to you to attend the Royan International Twin Congress which will definitely be a memorable occasion for developing lifelong friendships and collaborations in the coming years.
