Today we announce the launch of OvuFirst™, a completely unique patented sensor designed to measure skin temperature, providing women with an understanding of when to try and conceive naturally. This can also help determine if there may be any underlying issues in trying to conceive.
Fertility Focus, the manufacturers of the OvuCore™ and OvuSense Pro™ add OvuFirst™ to their family of leading fertility monitoring solutions that have class II medical device classification and 510k FDA clearance. OvuSense™ fertility monitoring family now supports couples from their first months of trying to conceive right the way through to monitoring clinical treatment.
OvuFirst™ is targeted at women who wish to monitor their ovulation and cycles in a convenient, non-invasive way by wearing the clinically-proven sensor on the arm or wrist overnight.
OvuFirst™ confirms a woman’s fertile window with over 90% accuracy even if she has irregular cycles, making it the most accurate skin-worn sensor on the market. The OvuSense App™ then uses this information to provide women with a full 8-day fertile window at the start of their next cycle.
The Fertility Focus team are driven by their own experiences with struggling to conceive. Their aim is to empower women by putting them back in control of the understanding of their cycles.
The resulting OvuSense fertility monitoring family improves the chance of successful pregnancy whatever a woman’s previous history and contributes to better treatment for common issues such as PCOS.
OvuCore™ predicts the onset of ovulation one day in advance  with 96% positive predictive value and 99% accuracy for detection of the exact date of ovulation .
OvuSense® Pro, is proven to help with screening and remote monitoring of treatment [2-5]. No other method of cycle monitoring in the clinic or home offers these features.
The company is continuously developing new technology to support women along all stages of their fertility journeys. The launch of OvuFirst™, is a unique patented sensor design to measure skin temperature. This provides women with a convenient method of cycle tracking for when they are just starting out on trying to conceive.
Fertility Focus also manages the largest closed support group on Facebook for women who have PCOS and are trying to conceive called PCOS Fertility Support Group.
Robert Milnes, CEO, Fertility Focus said, “We took our revolutionary OvuSense™ patented technology, which is proven in over 190,000 cycles of use. And then used it develop and test the most accurate skin-worn fertility monitoring sensor available on the market. We are proud to offer a convenient and easy-to-use solution to assist and support women during the early stages of their fertility journey. It is for both trying to start a family or simply learning more about their bodies and cycles.”
In a side-by-side study volunteers wore the OvuCore™ vaginal sensor and OvuFirst™ skin sensor overnight for several cycles.
The study concluded that the skin-worn sensor provides a convenient method of determining the presence or absence of ovulation. This was even for women who have a known history of ovulatory dysfunction, anovulation (the absence of ovulation), and/or abnormally long cycles.
The study is expected to be published later in the year.
Hina Mazharuddin, Physician’s Assistant and OvuFirst™ study participant commented, “I love how easy and comfortable OvuFirst™ is. OvuFirst™ provided me with a non-invasive way to collect data and see trends to better understand my personal health. As a medical provider who takes care of women’s health, I am looking forward to this being a wonderful resource for all women to understand, be informed and empowered to take control of their health.”
At the heart of the OvuSense™ fertility monitoring family is the ability to provide clinically proven, accurate and useful information so every woman can best understand her unique individual cycle pattern.
Robert Milnes continued, “For almost a decade, OvuSense™ has been at the forefront of breaking down the mythology surrounding the concept of what constitutes a normal cycle. Although traditional thinking holds that a large majority of women ovulate mid-cycle, only around 40% of OvuCore™ users show this pattern.” 
OvuCore™ works by measuring female continuous core body temperature (CBT) using a sensor worn in the vagina overnight.
Further ground-breaking clinical research led to the development of OvuSense® Pro, which provides doctors with detailed remote screening for potential causes of female sub-fertility, risk of miscarriage, and potential pregnancy complications [2, 3, 4].
A presentation at the Vitalis conference in 2020  detailed the added benefit of OvuSense Pro through a number of case studies: Because it can show what’s happening throughout the cycle. Women and their doctors can also use OvuSense Pro to track medications and treatment and understand if these are improving the regularity of ovulation and the chances of a successful pregnancy.
