Dr Derek Lok has major interests in different types of IVF treatment including embryo selection through preimplantation genetic diagnosis, recurrent miscarriage and IVF treatment failure management. Derek puts great emphasis on the identification and correction of the fundamental issues which are causing a specific couple to struggle to conceive and offers highly individualised treatment. 


Approximately 40%  of infertility amongst Australian couples is related to male factors and Derek specialises helping men overcome these issues. Specifically, Derek offers highly specialised medical and microsurgical treatments for men with sperm production problems, including sperm retrieval through micro dissection using a high power operative microscope to identify and selectively remove tubules within the testes that contain sperm while also minimising blood vessel damage and tissue removal. He also conducts microsurgical vasectomy reversal through small scrotal incision which results in rapid recovery. 

Derek is a certified advanced (Level V) endoscopic surgeon, specialising in fertility related gynaecological surgeries including laparoscopic tubal reversal and tubal surgeries, correction of congenital uterine anomalies, myomectomies (removal of uterine fibroids mostly minimally invasive through endoscopy, permitting same or next day discharge and rapid recovery), treatments of severe endometriosis and pelvic adhesions, conditions which not only may improve a patient’s natural fertility but also their fertility treatment outcomes
