RRM Research Updates: Hormonal monitoring of the menstrual cycle, with comparison to ultrasound

Presented by: Professor Leonard F. Blackwell


Please note the discussion following the presentation does not have a visual when those currently talking chose to have their video off so will appear as a black screen, but you can of course listen to the audio.

Grand Rounds is held monthly for health care professionals as part of RRM's Educational Webinar Series. Presentations aim to improve the clinician's foundational knowledge as well as highlight and encourage research and new methods in the area of Restorative Reproductive Medicine. These sessions should enhance the efficiency, effectiveness and quality of healthcare delivery, and in turn lead to improved patient outcomes.

Presented by Professor Leonard F. Blackwell, Massey University, New Zealand

Professor Blackwell is trained in organic chemistry, biochemistry and reproductive physiology. He studied under Professor James Brown at the University of Melbourne in the physiology of ovulation and in the development of the Fertility Meter, a device for monitoring ovarian activity in all its manifestations and one of the only true quantitative point-of-care devices in existence.  For the past 36 years, Len has been involved in research and development of urinary assays as point-of-care diagnostic kits and recently with quantitative immune-chromatographic assays. He has developed prototype tests for five different analytes relating to reproduction and fertility, and a device for overcoming the fluctuations in urine volume which has held back non-invasive point-of-care diagnostic tests.
