Faster Help for your Sub-Fertile Patient

OvuSense® Pro has been designed for your patients that are concerned about their fertility but are not ready (for whatever reason) to begin more advanced treatment. This can be patients with known or suspected conditions like PCOS, to patients that have just started trying but are anxious about their progress.

OvuSense Pro Portal

OvuSense Pro is designed to provide you and your patient with objective feedback as to the status of their reproductive cycle, on a cycle by cycle basis.
So your patients save time and money by getting to the heart of sub-fertility issues sooner.

OvuSense Pro is purchased by the patient and includes a web portal where you can check their progress at anytime.

The patient also gets full use of the individual OvuSense system using either OvuCore™ or OvuFirst™

OvuSense Pro is used to gain objective information so you can screen for conditions which may be causing sub-fertility, or help monitor treatments and/ or recommended dietary changes.

With OvuSense Pro you will be able to:

  • Objectively see important physiological indicators such as cycle length, and length of luteal and follicular phases.
  • Understand the best time in the cycle to carry out in-office tests such as serum progesterone, ultrasound folliculometry, and further hormone testing.
  • Create a treatment plan, and guide the patient more effectively as objective feedback is now available.

How it Works

On your laptop or mac, OvuSense Pro shows a chart of each reproductive cycle for each of your patients. The chart lets you see the length of the reproductive cycle, the follicular and luteal phases, and flags potential cycle issues based on a set of clinically published criteria. This helps both understand which diagnostic tests to conduct and the best timing of those tests. Blood for a serum progesterone, for instance, can be timed for draw 7 days after confirmed ovulation by OvuSense Pro as per ASRM recommendations.

Once a diagnosis is in place, cycle changes can be easily tracked to determine whether treatments and dietary change are having the desired effect.

The patient can also track key elements of their cycle on their mobile device. This helps them in a number of ways-it can help with the timing of sex, give them a better understanding of their cycle and provides a sense of control.

Example Screen

This example screen shows a cycle of 73 days with ovulation occurring on day 62. The luteal phase is 11 days long. This is the first of three cycles shown in the Case Study. The case study shows the progression from an atypical cycle treated by a physician with Letrozole to a cycle with much more 'normal' characteristics and balanced follicular and luteal phases.

The ability to see cycle changes easily is the main benefit of OvuSense Pro.

    View the Letrozole OvuSense Pro case study

    This case study covers three consecutive cycles. You will see the initial cycle is 73 days long, the next 47 days long. Then with Letrozole the cycle length is reduced to 32 days with ovulation on day 20.

    We see there is an issue with cycle length and late ovulation, then the clear change in cycle length as the result of the intervention.

    Cycle 1

    In this example the OvuSense user was 32 years old, trying to conceive 1-2 years before starting with OvuSense. During her first cycle of use a number of atypical cycle characteristics were identified, and although she ovulated it was late in the cycle.

    Cycle 2

    The late ovulation is repeated in cycle 2 and Letrozole was prescribed by her clinician at the start of the 3rd cycle.

    Cycle 3

    The Letrozole resulted in a much shorter follicular phase and ovulation nearer the middle of the month. OvuSense Pro successfully screens for cycle issues, provides actionable insights, and continued monitoring confirms (in this case) that treatment successfully restores ovulation.

    View the Miscarriage Avoidance OvuSense Pro case study

    This case study covers two consecutive cycles. You will see the initial cycle is 46 days long, with several unusual patterns are flagged by OvuSense Pro.

    The OvuSense user had one previous miscarriage. Her doctor decided to prescribe Letrozole and supplemented Progesterone in the following cycle and the cycle clearly returns to a normal pattern with sustained progesterone throughout the luteal phase after ovulation. The patient successfully conceived in the second cycle and stopped monitoring with OvuSense after 47 days.

    Cycle 1

    OvuSense Pro identifies Crash After Ovulation - this is a unique flag from OvuSense Pro which shows a risk of falling Progesterone after ovulation (potential Luteal Phase Insufficiency). Crash After Ovulation has been shown by clinical studies [1] to indicate an increased risk of miscarriage. As well as this OvuSense Pro identified a Short Luteal Phase, Late Ovulation and a Long Cycle are identified.

    Cycle 2

    The OvuSense user discussed these flags with her doctor. She had a previous miscarriage, so the doctor decided to prescribe Letrozole taken at the start of the cycle (shown by the first orange dot on the chart), followed by supplemented Progesterone after ovulation (shown by the second orange dot on the chart). The OvuSense user became pregnant in that cycle, miscarriage was avoided and she continued with her pregnancy after she stopped monitoring with OvuSense on day 47.

    Clinical Publications

    [1] 'Crash after Ovulation' is a novel cycle pattern characterised in Hurst B, Pirrie A (2019),where temperature (and therefore progesterone) was observed to fall rapidly after ovulation before the onset of the next period. Hurst B, Pirrie A (2019) showed that it occurs in 12.0% of total cycles from 16.0% of OvuSense users, so it is a common cycle characteristic that doesn't follow a typical pattern. As it suggests high progesterone falling after ovulation, it is thought to be associated with Luteal Phase Insufficiency and sometimes occurs alongside a 'short luteal phase'. Hurst B, Karoshi M (2020) shows a strong association with those that had a previous miscarriage
