Research to Remember
A British study that linked risk of stillbirth to the father's amount of exposure to workplace radiation determined that stillbirth increased by 24% for each millisieverts (mSv) of radiation a man had been exposed to in his lifetime. For every 10 mSv of exposure in the 90 days before conception, the odds of stillbirth rose by 86%. Records of 9208 births between 1950 and 1989 in county Cumbria where the fathers were employed at a nuclear plant revealed significantly more stillbirths among women whose partners were employed at the nuclear plant than among women whose partners were not employed there, when data were standardized for year, social class and birth order.

Mammals in general and women in particular control the pain of labor by releasing morphinelike substances called endorphins. It has been demonstrated that these endorphins stimulate the secretion of prolactin, the key hormone of lactation.
Oxytocin is necessary for the contraction of the uterus during labor and also for the contraction of the breast during the milk ejection reflex, when the baby is sucking. It is questionable whether women who have had no labor can release oxytocin as effectively as those who gave birth in physiological conditions. A Swedish study found that two days after birth, when the baby is at the breast, women who gave birth vaginally release oxytocin in a very pulsatile—therefore effective way—compared with women who gave birth by emergency cesarean section. The study found a correlation between the way oxytocin is released two days after birth and the duration of exclusive breastfeeding. In other words, the duration of breastfeeding seems to depend on how the baby was born. The same Swedish team found that the cesarean women laced a significant rise in prolactin levels at 20-30 minutes after the onset of breastfeeding (1).
An Italian study found that the amount of endorphins in breastmilk of the first days is much higher among mothers who gave birth vaginally compared with mothers who underwent cesarean section (2). It is probable that one of the effects of morphinelike substances is to induce a sort of addiction to mother's milk. One can anticipate that the more addicted to the breast the newborn baby becomes, the longer and easier the breastfeeding.
It seems more important, where the initiation of lactation is concerned, to contrast "cesarean during labor" with "scheduled cesarean." Nonlabor cesareans seem to be associated with more breastfeeding difficulties. We can easily offer an interpretation: when the time of birth has been planned, mother and baby have not been given the opportunity to release the hormones involved in both childbirth and lactation. A study from Turkey compared the starting time of lactation and the amount of milk produced within 24 hours among several groups of cesarean births. Researchers found that the beginning of lactation occurred earlier and the amount of milk produced was higher among women whose second cesarean was performed during labor, compared with women whose second cesarean was scheduled (3).

Preliminary data and related research on the pregnant uterus suggest that breastfeeding and healthy term births are quite compatible. The specter of breastfeeding-induced preterm labor appears to spring from an incomplete understanding of the interactions between nipple stimulation, oxytocin and pregnancy.
The first little-known fact is that during pregnancy *less* oxytocin is released in response to nipple stimulation than when a woman is not pregnant (1). The key to understanding breastfeeding during pregnancy is the uterus itself. Contrary to popular belief, the uterus is not at the beck and call of oxytocin during the 38 weeks of the preterm period. Even a high dose of synthetic oxytocin is unlikely to trigger labor until a woman is at term.
Oxytocin receptor sites, the uterine cells that detect the presence of oxytocin and cause a contraction, are sparse up until 38 weeks, increase gradually after that time, and increase 300-fold *after* labor has begun. In order for oxytocin receptor sites to respond strongly to oxytocin, they need the help of special agents called "gap junction proteins." The absence of these proteins renders the uterus down-regulated, or relatively insensitve to oxytocin even when the oxytocin receptor site density is high. And natural oxytocin-blockers, most notably progesterone, stand between oxytocin and its receptor site throughout pregnancy (2,3,4). The uterus is in baby-holding mode, well protected from untimely labor.

The Cost of Not Breastfeeding
- U.S. families spend $2 billion a year on human milk substitutes such as artificial milk, otherwise known as formula.
- It costs an additional $1.3 billion to cover sick-child office visits and prescriptions for respiratory infections, ear infections and diarrhea in nonbreastfed infants during the first year of life.
- In the first year of life, it will cost more than $25,000 to treat lower-respiratory infections in 1000 never-breastfed infants.
- The cost of treating Type I diabetes in formula-fed children is more than $1 trillion.
- Private and government insurers spend a minimum of $3.6 billion a year to treat medical conditions and diseases preventable by breastfeeding.
- Formula has a long history of recalls for bacterial contamination or mis-manufacture that has in many cases resulted instances of illness, permanent injury of death.
