Lunar Cycles and Fertility

By Dr. Holly German, N.D.

“All fluid energy from the earth responds to the moon cycles”
-- Rosemary Gladstar

Human beings have always been inextricably tied to the moon and its cycles. The moon has long lit the way for nighttime activities and divine rituals. We have an innate sense of the moon’s esoteric power, but have little knowledge about how its existence affects our physical bodies. We do know that the moon cycle is 28 days, the same exact number of days as the female menstrual cycle – common sense tells us that this link is too profound to chalk up to coincidence, but what does it really mean?

Tradition tells us that the new moon is a time for introspection and rest. The new moon is the time for the menstrual cycle to begin. After the new moon waxes for 14 days, we see the full moon in the sky. Tradition tells us that the full moon is a time of celebration, of increased vitality, and ovulation.

 Recent research on the intricacies of the reproductive cycle and fertility has focused on the pineal gland. This gland is often referred to as the tangible “Third Eye.” The pineal gland is light sensitive and secretes melatonin in response to darkness. After being excreted from the pineal gland, melatonin sends a message to the hypothalamus which then sends a message to the pituitary gland. The pituitary gland then releases hormones which affect the ovaries, testicles, thyroid, and adrenal gland. This cascade affects both female and male fertility.

Since the pineal gland sets off an endocrine cascade in response to fluctuations in lightness and darkness, it makes sense that people who slept out under the fluctuating light of the moon had an intimate relationship with the effects of the lunar cycles on the rhythms of their bodies. It also makes sense that in our light polluted world hormonal imbalances are at an all time high.

So what can you do to keep your reproductive cycle regular and in tune with the lunar cycle? Louise Lacey, author of “Lunaception” recommends adjusting the lights in your bedroom to more closely mimic the light of the moon. 

  • Days 1-13 (day 1 being the new moon) – sleep in total darkness (eliminate any trace of light through windows or under doors.

  • Days 14-16 – (the full moon) sleep with a small light on all night or with the curtain open (~40 watts)

  • Days 16-28 – total darkness again

  • Repeat!
