Galactorrhea, Milk Consumption and Fertility
from the book Fertility, Cycles and Nutrition by Marilyn M. Shannon
New research provides evidence that in some women milk consumption may be related
to decreased fertility as they age as well as early menopause. This is because a sugar
found only in milk, galactose, is harmful to the ovaries. When the original milk sugar,
lactose, is digested, two smaller sugars, glucose and galactose, are produced.
The liver quickly takes up the galactose and converts it into glucose, so that what we
call “blood sugar” is all glucose. However, some women cannot make this conversion
well, and they have galactose circulating in their blood. The galactose apparently is
harmful to the unfertilized eggs, which must continue to develop before ovulation.
Should you restrict milk products?
If you have unexplained infertility or cycle irregularities, especially secondary infertility in
your thirties, ideally you could have your blood tested for the presence of galactose. A
negative test after drinking milk would conclusively show that this is not your problem. If
you cannot find a physician willing to test your blood, in addition to the other nutritional
suggestions here, you may wish to avoid all milk products except for butter for six to nine
months, charting your cycles so that you can observe any improvement in mucus and
Butter is purely fat and is an essential fatty acid of sorts – important to note that many women
believe it is best to drink skim or 1% milk. This is not true because that makes it more milk,
less fat and the fat is not what people have a problem with. After all, we are not cows and do
not need to “nurse” our whole lives. Even cows stop drinking cow’s milk. (Something to think
This is from another section in the same book:
Galactorrhea, or milk in the breasts of non-nursing women, is not uncommon among those
who have been pregnant. It most often indicates excessive prolactin secretion, or it can be
a symptom of hypothyroidism, or more rarely hyperthyroidism. End of article from Fertility,
