Inside CRGH: Expanding our clinical leadership with two senior fertility specialists

08.06.2026

Finding the right fertility clinic in London often comes down to one thing: the expertise of the clinical team. For individuals and couples navigating complex fertility journeys, having access to advanced diagnostics and personalised care is vital.

To meet this growing demand, we would like to introduce two highly accomplished senior fertility specialists to our Great Portland Street clinic: Ms. Yeliz Atik and Mr. Onur Basegmez.

These new appointments represent our continued investment in our diagnostic capabilities, particularly in advanced gynaecological ultrasound, reproductive endocrinology, and cutting-edge fertility treatments.

 

 

Ms. Yeliz Atik: Expert in advanced gynaecological imaging & reproductive endocrinology

Ms. Yeliz Atik, MBBS, MD, joins CRGH as a consultant obstetrician and gynaecologist, bringing over 20 years of international experience in women’s health. After completing her specialist training in Turkey, Ms. Atik moved to the UK to further her expertise in reproductive medicine, which included a prestigious tenure at University College London Hospital (UCLH).

Revolutionising diagnostics for endometriosis and adenomyosis

One of Ms. Atik’s core clinical strengths is her specialism in advanced gynaecological imaging. By utilising state-of-the-art diagnostic tools like 3DSIS (3D Saline Infusion Sonography) and HyCoSy (Hysterosalpingo-Contrast-Sonography), she provides patients with a thorough assessment right at the start of their fertility journey.

This level of detailed imaging is key for patients dealing with complex conditions such as:

    • Endometriosis

    • Adenomyosis

    • Recurrent pregnancy loss

With a more accurate diagnostic starting point, Ms. Atik designs highly tailored, evidence-based treatment plans that address structural or hormonal barriers to conception. Her wider clinical interests also include medical egg freezing, managing male subfertility, and navigating complex reproductive endocrinology. She is widely published in peer-reviewed journals and is a regular contributor to international fertility conferences.

 

 

Mr. Onur Basegmez: Bridging stem cell science and advanced IVF care

Also joining our senior clinical team is Mr. Onur Basegmez, MD, MRCOG. A graduate of Marmara University in Istanbul, Mr. Basegmez received extensive training in In Vitro Fertilisation (IVF) at Acıbadem University, which is a globally recognised institution for providing medical education.

Having practiced in the UK for over five years, Mr. Basegmez has earned a reputation for managing intricate fertility treatment pathways with an unwavering focus on continuity of care.

A unique edge in stem cell engineering

What sets Mr. Basegmez apart is his academic and research background. Holding a master’s degree in Stem Cell Engineering from Istinye University, he bridges the gap between high-level laboratory research and clinical practice. This detailed understanding of cellular biology allows him to bring an innovative perspective to the IVF process, benefiting patients with complex or previous unsuccessful fertility cycles.

A shared commitment to personalised, patient-first fertility treatment

At CRGH, we understand that each fertility case is different – there is no one size fits all. Our latest appointments reinforce our commitment to providing our patients with the highest quality bespoke care.

Dr. Wael Saab, fertility consultant and senior medical director at CRGH, highlights why these appointments are so timely:

“In the current fertility landscape, patients require more than standard protocols; they need accurate diagnosis and clinicians who understand the nuances of reproductive endocrinology.

CRGH is renowned for its highly personalised, patient-first approach. Mr. Basegmez and Ms. Atik dedicate themselves to providing individualised support through evidence-based care, supporting their patients and their partners throughout every stage of their fertility journey.”
