It is getting dark here now, a black night without a moon to be found with a quick glance. We are starting to see our breath in the mornings, with a bit of frost on the windshield. My favorite time of year is fall. I just can't get enough. Summer is always too long for me and winter comes too quick.

I was looking into a product called the Conception Action Pack. Typical things like charting your cycle are described and the pack seems pretty straight forward. When the advertisement began to explain more in depth about the cycles of the moon, I was instantly interested.

The Moon and its Effects on Female Fertility.
Intuitively, women have always understood that the moon, their menstrual cycles and fertility are intimately connected.

In folk lore and ancient traditions the connections between the three are taken as fact.

Consider the following:

A healthily fertile woman's menstrual cycle runs its course in about twenty-nine days, one lunar cycle.


A standard healthy pregnancy runs for 42 weeks or 10 lunar months.


The relationship between the moon's cycles and menstruation is so fundamental. that the two phenomena are related linguistically. Our words, ‘menstruation,’ ‘moon,’ and ‘month,’ all come from the Greek word for ‘measure of time.’

Science Confirms the Moon / Menses Link
Recent scientific research has shown that whilst sunlight stimulates your body clock to produce its sleep / wake rhythm it is the moon which controls the function of the menstrual / fertility cycle.

Female ovulation and the menstrual cycle are controlled by the hormone Melatonin, which is produced by the pineal gland during periods of darkness.

In 2001 scientists at Jefferson Medical College worked out how the human eye uses light to regulate melatonin production.

They found a unique photoreceptor in the eye responsible for reacting to light. This receptor sends a signal to the pineal gland which regulates the levels of melatonin depending upon the level of moonlight detected by the eye.
