About Me
Dr Derek Lok is an O&G, Fertility Specialist and Advanced Endoscopic Reproductive Microsurgeon.
Dr Lok is one of a handful of fully-qualified fertility sub-specialists in Sydney that have completed the CREI qualification, and one of an exceptionally limited number of reproductive microsurgeons operating in Australia. He is a certified advanced (Level VI) endoscopic surgeon, specialising in fertility related gynaecological surgeries.
This combination of medical, clinical and surgical expertise allows Dr Lok to manage his patients with a wider range of treatments options to help them achieve pregnancy and is a contributing factor to his higher than average conception success rate.
Dr Lok obtained his medical degree (MBBS) in Hong Kong and completed his PhD at the University of Adelaide, Australia in 1994, which was focused on Feto-Maternal Medicine. Following this, he undertook specialist training as an Obstetrician and Gynaecologist (O&G) in Sydney and Adelaide, and was awarded Fellowship of Royal Australian and New Zealand College of Obstetricians and Gynaecologists (FRANZCOG) in 2001.
He then undertook additional sub-specialist training in reproductive endocrinology and infertility in Adelaide and the United Kingdom, focused on reproductive microsurgery and endoscopic surgery for females and males, and achieved the Certificate of Reproductive Endocrinology & Infertility (CREI) in 2002.
Since 2002, Dr Lok has been working as a fertility specialist for the last 25+ years.
In addition to his clinical duties, Dr Lok is a senior clinical lecturer at The University of New South Wales (UNSW), a role which involves undergraduate teaching, specialist and sub-specialist training for advanced trainees and scientific research.
Dr Lok offers his patient treatment options through both the private and public systems for those unable to afford the private system.
Dr Lok speaks fluent English, Mandarin and Cantonese.
What is CREI?
Dr Derek Lok has achieved the Certificate of Reproductive Endocrinology & Infertility (CREI) qualification, which is the highest qualification in fertility medicine that doctors in Australia can achieve.
CREI membership is strictly limited to those fertility specialists who can demonstrate at least 15+ years of dedicated training and patient care in fertility medicine.
Although many specialists may provide care for infertility and perform IVF, fewer than 100 specialists across all of Australia and New Zealand have achieved the very special distinction of CREI (out of more than 2,000+ obstetricians and gynaecologists across all of ANZ).
