I practiced as a specialist at Istanbul University Cerrahpasa Medical Faculty, Department of OB&GYN under the division of Reproductive Endocrinology/Infertility and IVF between 1997-2019, during which I received the degrees as associated professor and professor.

I founded Endometriosis and Adenomyosis Society, Turkey in 2009 and also serving actively as an executive board member. I was appointed as World Endometriosis Society Senior Ambassador in March 2019. I have 67 peer-reviewed articles in international academic journals, 27 of which are on endometriosis,. My research is mainly focused on endometriosis, ART and infertility.

Relevant publications

I founded Endometriosis and Adenomyosis Society, Turkey in 2009 in order to enhance both academic awareness and interactions among physicians and also to increase patient awareness in Turkey. With the power of the association, we organize many scientific courses, seminars, webinars and patient events in the field of endometriosis every year. You can visit the website for more detailed information . In the light of these academic activities we published the ‘Turkish Guideline of Diagnosis and Management of Endometriosis‘ which I chaired. I also contributed to the latest ESHRE, 2022 Endometriosis Guideline under the ‘pain section’.

Apart from these activites, with the support of endometriosis experts from the Turkish Endometriosis and Adenomyosis Society and under my supervision and along with the collaboration of several centers around Turkey we have initiated ‘Turkish Endometriosis- Adenomyosis BioBank’ project. The aim of the biobank project is to recruit endometriosis and adenomyosis patients and store their blood and serum samples which will be used in studies in the future. For the collection of data, tissue and samples WERF EPHect protocol which were also previously translated to Turkish languge will be used.
