The Natal Astrology Chart, and the many Astrological techniques, provide the Astrologer with a seemingly endless amount of information about an individual. A great deal of information, for example, can be gleaned about an individual’s fertility and challenges to fertility.
Plus possible ways to further enhance fertility, overcome fertility challenges on physical, emotional, mental, and spiritual levels, understand the timing of challenges, and to choose the most auspicious times and avoid inauspicious times for conception.
In terms of fertility, the Moon is the most important planet for both men and women. The Moon rules the entire reproductive process, but reproduction is such a huge and essential function of every specie, that all the planets have some involvement and influence.
Before I go into more details about the Moon, her phases, and conception, I would first like to present a brief overview of Astrology and fertility. An Astrologer is able to see by looking at the individual’s chart any fertility challenges, if indeed any. It is also possible to see whether they are operating on the physical, emotional, mental or spiritual level, and if the challenges are ongoing or transient in nature.
Organs, Functions + Astrology
Different organs and functions of the body are associated with different planets and Astrological signs and houses. For example, sex is ruled by Pluto and Scorpio. The penis is ruled by the 8th house of transformation as well as Pluto, Mars, and Scorpio. The menstrual cycle is ruled by the 5th house of creativity and children and the 8th house, as well as the Moon. Seminal fluid is ruled by the Moon while the sperm is ruled by Scorpio, Venus, Jupiter, and Mars. The ovaries are ruled by Venus, Libra, Scorpio, and Pluto. Lust and sex appeal are ruled by Venus and Mars. Creativity and vitality are ruled by the Sun. Sex hormones are ruled by Mars and Venus.
As a rule of thumb, any physical and hormonal differences between males and females are ruled by Mars and Venus and the symbols used in Astrology to depict theses planets are the same symbols used for male and female in a wider sense, including by scientists.
Conception Timing + Astrology
Astrology can be key to conception timing.
For example, Astrology can be used to pick the best time to implant eggs in IVF, by avoiding particularly difficult aspects to the Moon. When the Sun and any major planets are in opposition, something an Astrologer can easily check, there is an increase in sunspot activity, magnetic storms, shifts in magnetic fields, and cosmic radiation.
Dr Eugen Jonas, who also discovered the Lunar Peak (see below) found these can have subtle and sometimes not so subtle deleterious effects on germs cells as well as newly fertilized eggs.
As a mother of a child with a birth defect and now in my 40s, this is something I would investigate if I decided to conceive another child.
Sometimes there are transient challenges to fertility. A particular client always comes to mind when I illustrate this phenomenon. When she came to see me, she and her husband had been trying for their second child for over two years. They had both been fully checked for physical fertility issues and nothing was found to be wrong. When I looked at her chart I immediately noticed that the asteroid Chiron was transiting through her 5th house of creativity and children. This means that Chiron was not in her 5th house when she was born, but was temporarily passing through and had been for over two years.
Chiron in the 5th house is linked to fertility challenges. While this can sometimes be overcome in a birth chart, I felt it was unlikely that pregnancy would be possible until Chiron had moved into the 6th house. The problem was that she was past her mid-30s and Chiron would be in her 5th house for nearly another five years.
I was very vague about the timeline because I was an inexperienced Astrologer at the time and didn’t want to upset her. Plus I didn’t want to plant any firm ideas in her mind that pregnancy would not be possible for the next five years. You just never know – very unexpected things can happen.
As it turned out, one month after Chiron left her 5th house she fell pregnant naturally. After a smooth pregnancy, she gave birth to a healthy child at nearly 42. She and her husband had tried everything in the interim but in this case, it all came down to timing.
The Moon + Fertility
Steiner’s vision was that in the past, all women had their menstrual cycle perfectly synchronized with the lunar cycle… and the fact that this is no longer the case indicates an emancipation from cosmic cycles.
The words for menstruation are derived from classical roots meaning month and Moon. Many cultures have made a connection through history between the Moon, women, and fertility. The length of the average menstrual cycle is 29.5 days which is the same length as a lunar month.
In Astrology, the Moon rules the breasts, stomach, uterus, and digestion as well as bodily fluids, including amniotic fluid, vaginal mucus, and semen. The Moon, like the uterus, constantly changes shape.
According to Samuel Sagan, author of Planetary Forces, Alchemy and Healing, the uterus’s functions are a perfect embodiment of the symbolism of the Moon and that of Cancer, the sign it rules. The uterus provides a “nidus” or nest for reproduction where the foetus can grow and be nurtured in a warm, fluid-filled protected environment.
A commonly held view is that women are most fertile at full Moon and so should ovulate at this time, and menstruate at the new Moon, but clinical observation and research indicate that lunar cycle synchronization is not so simple. It has been observed that women are often fertile and conceive at full Moon, even when this does not coincide with mid-cycle ovulation.
Moon Phase + Mid-Cycle Ovulation
Several researchers have established that this bio-rhythm is like a blueprint for the hormonal cycle, and that the more relaxed, and generally reproductively healthy a woman is, the more likely she is to experience her mid-cycle ovulation at the same phase of the moon that was present at her birth.
Francesa Naish, Naturally Fertility Specialist, Australia
In the 1950s, Dr Eugen Jonas, a Czech Psychiatrist, “identified and assessed a biorhythmic cycle as having an effect on fertility…he concluded that a woman is fertile during the same phase of the Moon that was present when she was born, regardless of whether she was at mid-cycle ovulation.” (Naish)
However unlikely this may seem, this finding has been extensively tested by many practitioners and researchers.
Further to this, it appears that when a woman is mid-cycle during her birth lunar phase, she is more likely to conceive. The synchronization of the lunar and hormonal cycle has been observed to occur more commonly in woman who are aware of their bodies, such as those who are checking their mucus symptoms, or those who are trying to conceive because they are taking care to be more reproductively healthy. You can read more about mucus symptoms in relation to fertility and natural contraception in Francesca Naish’s books, The Natural Way To Better Babies and Natural Fertility.
If the menstrual cycle is longer or shorter than a lunar cycle, it may not synchronize with this lunar blueprint and the lunar peak may not coincide with ovulation. Dr Jonas found that in these situations, women were still able to conceive at the lunar peak.
In a study published in the journal “Fertility and Sterility,” Pierson and his colleagues found that of the 63 women they studied, only 50 had “normal” menstrual cycles. 13 of the 63 women ovulated multiple times, in various different ways, and of the other 50 women, 40% experienced up to three waves of the follicles instead of the expected one. Any one of these follicle waves could have resulted in the production of an egg. The women’s hormonal levels did not match this activity and so it follows that measuring hormones in the blood is not enough to predict what is happening in a woman’s reproductive system.
Out of mid-cycle ovulations are called spontaneous ovulations and other studies have confirmed that ovulation can also occur out of cycle as a response to sexual stimulation. The woman’s lunar peak cycle is usually the priority, but if conception attempts according to the women’s cycle have been unsuccessful, experimenting with sexually stimulated spontaneous ovulation might prove successful. The optimum time for this would be during the man’s lunar peak, when sperm count is at its highest.
The lunar peak is found by calculating the angle between the Moon and the Sun at the time of birth, then the monthly return for that angle is calculated by an Astrologer or an Astrological or Astronomical computer program. This will produce 12 or 13 times in a calendar year, one every 29.5 days. The woman is fertile at these times whether or not these dates coincide with her mid-cycle ovulation. Women have also conceived at full Moon even when this did not coincide with their lunar peak or their mid-cycle ovulation.
According to Naish, to increase conception success it is preferable for the ovulation and lunar peak to be synchronized. The following is a list of some ways that have been found to predispose women to ovulating at this lunar peak: becoming generally and reproductively healthy through improving diet and exercising adequately but not much, reducing stress, avoiding international air travel and shift work (which are known to disrupt cycles), and being aware of lunar phases.
Medical Astrology can be used to suggest with the Astrological Moon and Sun sign particular foods and activities that can help create harmony and balance, which may assist the synchronization of these cycles.
To conclude, Astrology is a useful tool for understanding an individual’s fertility and fertility challenges. This can be used to increase fertility and the chances of conception and to provide very practical help in the form of fertile times that fall outside of the mid-cycle ovulation period.
