Plain English Summary

Background and study aims
The Inito Fertility Monitor is intended to be used for the measurement of hormone levels in urine samples. The system is intended for home use by people or point-of-care (POC) use by a trained health care professional as an aid in the diagnosis of infertility. The aim of this clinical study is to evaluate the performance of the Inito Fertility Monitor in the measurement of three key fertility hormones: luteinizing hormone (LH), estradiol glucuronide (E3G), and pregnanediol glucuronide (PdG) using urine samples.
.
Who can participate?
Adult women aged between 21 and 45 years of age with an average menstrual cycle length of 21 to 42 days.

What does the study involve?
Clinical performance of the Inito Fertility Monitor will be compared to two other methods for measuring hormone levels: the Clearblue Fertility Monitor and a laboratory investigation called ELISA.

Participants will collect urine samples at home every day for the duration of one menstrual cycle (the time from the first day of their period to the day before their next period) and these will be tested with Inito Fertility Monitor and Clearblue Fertility Monitor. Inito Fertility test strips and Clearblue test strips were dipped in the samples for 15 sec and after 5 min, readings from the respective devices were recorded. The samples for assessment with ELISA will be also collected from the users and transported to the investigational centre in dry ice within 30 min of collection.

What are the possible benefits and risks of participating?
Around 45-50% of women are unaware of their fertile window. The fertile window may vary depending on various factors such as age, lifestyle, or genetic predisposition. Previously it has been shown that estrone-3-glucuronide (E3G) and luteinizing hormone (LH) can be used to identify the fertile window. Also, anovulatory cycles occur in around 37-42% of natural cycles. Therefore, the confirmation of ovulation is sought after by both clinicians and patients and an additional measurement of pregnanediol-3-glucuronide (PdG) can be used to confirm ovulation. By taking part in this study, participants can identify their fertile window and hormone concentrations throughout the cycle, if their hormone fluctuations are as expected or do the hormones behave abnormally, and if their menstrual cycles are ovulatory or anovulatory.

No risks have been identified as being associated with taking part in this trial.

Where is the study run from?
Sparsh Hospital (India)

From June 2019 to December 2019

Scientific titleValidation of Inito Fertility Monitor with respect to laboratory measures of fertility related hormones
Study hypothesisThe Inito Fertility Monitor can measure concentrations of urinary hormones estradiol glucuronide, luteinizing hormone, and pregnanediol glucuronide with laboratory-grade accuracy and can predict the fertile days in women accurately
Ethics approval(s)Approved 21/05/2019, Sparsh Hospital Institutional Ethics Committee (146, Infantry Road, Opposite to Police Commissioner's Office, Bengaluru 560001; +91-80-61222000; enquiry@sparshhospital.com), ref: CLIN/INI/001
ConditionFemale infertility
InterventionUrine samples were collected by each participant at home every day for the duration of one menstrual cycle. The samples were frozen by putting the samples in the cold box container provided and sent to the testing site. The box provided contained a temperature logger in order to ensure that the temperature is maintained during transport to the testing site. The testing was done at the Inito laboratory situated at Bionest, IKP Eden, 16, Bhuvanappa Layout, Tavarekere Main Rd, Bengaluru, 560029.

Urine samples were tested with both the Inito Fertility Monitor and Clearblue Fertility Monitor using test strips for the respective devices. Inito Fertility test strips and Clearblue test strips were dipped in the samples for 15 sec, and, after 5 min, readings from the respective devices were recorded.

Each volunteer was assigned a unique ID. 3 participants were randomly selected and samples over the course of 1 cycle for each of these participants were collected for comparison of Inito and enzyme-linked immunosorbent assay (ELISA). The samples were collected from the participants and transported to the investigational centre in dry ice within 30 min of collection. The samples were aliquoted into 2 ml tubes and stored at -20°C in order to preserve the concentration of all the hormones.
