Menstruation and Ovulation Study (MOS)

Want to learn more about your cycle?

CeMCOR is pleased to announce that we have reached our goal of recruiting 600 women for this study. As of March 2008, we will no longer be enrolling any new participants. Thank you to all the 600+ women who helped us achieve this goal! We look forward to analyzing the data and publishing the results.

Who can participate in this study?

Are you a woman who:

  • is between the ages of 20 and 40?
  • has menstruated within the last 3 months?
  • has not used oral contraceptives/hormones within 3 months?
  • has not had a hysterectomy?

If you responded "Yes" to all 4 questions – we welcome you to this study!

What is the purpose of this research?

We want to find out if the signals your body gives you indicate whether or not you have ovulated (released an egg). This study aims to give both doctors and women a better understanding of the complex workings of women's menstrual cycles.

Why is this research important?

It is not generally well known that women with regular menstrual cycles can have subclinical anovulation (lack of egg release) which goes undiagnosed. Identifying anovulation in women is important because it is linked to infertility, bone loss, heavy flow and anemia in young women. In menopausal women, a history of anovulation is linked to endometrial and breast cancers, and possibly cardiovascular disease.

What would I be asked to do?

You will be asked to keep a menstrual cycle diary for one month, and to collect 8 urine samples during that time (urine samples are taken at home - no trips to the lab are needed). There will also be two interview sessions, one each at the beginning and end of your cycle. These will take place at our offices at VGH.

How will I benefit from participating?

Each woman will receive their personal hormonal analysis of estrogen and progesterone. You will also receive a copy of an educational DVD featuring Dr. Jerilynn Prior at the end of the study.
