The ABC’s Of Osteoporosis Prevention For Menopausal Women

Menopause means graduation! One year has passed since the last menstrual period—perimenopause is over. Because of the hormonal changes of the first few years after menopause, bone renovation is more rapid and risks for bone loss are greater. Thus we must continue habits that will keep bones healthy for the rest of our lives.

Painful Periods

Painful periods are known as cramps. This section looks at what causes cramps and how to ease the discomfort. Doctors call painful periods or crampsdysmenorrhea.” They are caused by high levels of prostaglandins, a kind of hormone that increases the normal squeezing or contraction of the muscle in the wall of the uterus.

Documenting Ovulation with Quantitative Basal Temperature (QBT)

If our cycles are regular - about a month apart we assume we are ovulatory - meaning releasing an egg and making normal amounts of progesterone. However, ovulation is highly variable for all women. Progesterone raises our first morning (or basal) temperature a little bit. But so do many other things. Thus "basal body temperature" (BBT) charts, even with mid-cycle stretchy mucus (symptothermal methods) may not be accurate for predicting ovulation. Therefore we developed a valid and scientific use of basal temperature called "Quantitative Basal Temperature" (QBT) to assess ovulation and the luteal phase length (number of days of progesterone elevation).

Progesterone (not Estrogen) for Hot Flushes in Perimenopausal and Menopausal Women

In less than a year, two influential articles reporting on consensus recommendations for therapy of “menopause-associated” and “menopausal” symptoms concluded that estrogen (with or without progestin) is the optimal therapy.
The purposes of this article are to propose that progesterone therapy is an equally or more effective hot flush/night sweat therapy than estrogen and to show that progesterone is safer than estrogen or estrogen with progestin (a synthetic cousin of progesterone) therapy.

Beyond “Estrogen Deficiency”—news from Women’s Health Initiative

When the USA’s National Institutes of Health announced that the Estrogen arm of the Women’s Health Initiative was stopped early, no one could ever say again that estrogen therapy prevents heart disease. Estrogen treatment in women who had undergone hysterectomy was associated with neither benefit nor harm for heart disease and caused a 40% increase in stroke.

Perimenopause is a time of “Endogenous Ovarian Hyperstimulation”

Perimenopausal endogenous ovarian hyper-stimulation” is the exact opposite of “The Myth of the Shriveling Ovary”: High estrogen levels during perimenopause, coupled with characteristically intermittent ovulation, can explain much of the misery of perimenopause.

The Death of Hormone Replacement Therapy — Why and how to use Ovarian Hormone Therapy

Dr. Jerilynn C. Prior, Scientific Director of the Centre for Menstrual Cycle and Ovulation Research, has never advocated the use of hormones as an ongoing "replacement" for menopause. She does not feel that menopause is a medical condition that needs to be "fixed". Rather it is a normal stage of life. She strongly advocates use of new term for the few women who do need therapy in menopause. The new term is: Ovarian Hormone Therapy.

Manipulating Menstruation with Hormonal Contraception — what does the Science say?

Articles and magazine reports and even books about so-called “menstrual suppression” describe taking the Pill continuously or for longer than 21 days with seven days off. The advertising suggests that this is giving women a “choice” to do away with menstrual flow or menstrual problems. The Federal Drug Agency in the USA has approved one oral combined hormonal contraceptive to be taken in four extended cycles a year. These new ways of taking the Pill allow companies a new patent on old drugs and make it likely that the market for these products will expand from those who want to control pregnancy to those who want to eliminate menstrual flow.

Enrolment complete: Perimenopausal Hot Flush Study

Enrolment is now complete. Thank you for your interest.
CeMCOR is now recruiting Canadian women for this CIHR-funded randomized controlled trial to test whether oral micronized progesterone is more effective than placebo as therapy for hot flushes and night sweats in perimenopausal women.
