Scientists have hypothesized that very early exposures to environmental chemicals (including disinfection by-products (DBP) and bis-phenol-A (BPA)) may have both short-term and long-term health effects on growth and development. Previous studies have been limited by a couple’s inability to recall exposure to chemicals at the time of conception and during pregnancy. By identifying the date that pregnancy started, scientists can help determine when testing should occur during pregnancy in order to match important developmental milestones. Methods exist to determine the most fertile day using lab tests, but they are expensive and not practical for long-term use. The Home Observation of Periconceptional Exposures (HOPE) Study will use a novel and simple method for determining ovulation/conception near the time that it occurs, known as the Peak Day method.

If you are a couple (women 18-35 years and men 18-40 years) planning to conceive with no history of infertility or medical conditions likely to cause sub-fertility and live within an hour’s drive from the study center (University of Utah), you may be eligible to participate in the HOPE Study. Participants will be provided with materials to learn a simple method for fertility tracking and receive compensation for their time. There are no blood draws or clinic visits.

Waking (Basal Body) Temperature


Hello HOPE participants! We wanted to share some information about waking (basal body) temperature.  

What is waking (basal body) temperature?

Waking (basal body) temperature is an easily observable fertility sign. Most women experience a rise in their waking temperature of at least 0.3oF a day or two after ovulation. A woman’s preovulatory waking temperature typically ranges from 97.0 to 97.7 oF, but some women can be lower. Postovulatory temperatures typically rise to about 97.8 oF and higher. After ovulation, temperatures will stay elevated until the woman’s next period, about 12 to 16 days later. When interpreting temperatures, it is important to look for a pattern of highs and lows. You will find that before ovulation your temperatures will go up and down in a low range and that after ovulation your temperatures will go up and down in a high range. The trick is to see the whole, and not focus on the day-to-day changes. Use the chart below as an example.



How to take your waking (basal body) temperature

Take your daily temperature first thing upon awakening, before any other activity including drinking water or getting up to use the bathroom. You should take your temperature about the same time every morning, give or take about an hour. Take your temperature orally, under the tongue. Try to maintain as much consistency as possible, including recording your temperature about the same time and getting at least three consecutive hours of sleep before doing so. Do not take your temperature multiple times as the longer you are awake, the more variable your temperature will be. In summary, take your temperature first thing after wakening and record that first reading.
