Seizing on yet another natural experiment, Almond examined the impact of the introduction of the food-stamp program in the late 1960s and early 1970s. The program was rolled out on a state-by-state basis, allowing Almond to compare birth outcomes for poor women who received food assistance during pregnancy to those…
The notion of prenatal influences may conjure up frivolous attempts to enrich the fetus, like playing Mozart through headphones placed on a pregnant belly. In reality, the nine-month-long process of shaping and molding that goes on in the womb is far more visceral and consequential than that. Much of what a pregnant…
May conducted a study of the effects of maternal exercise on the fetus. Comparing sedentary pregnant women to those who engage in moderate-intensity aerobic exercise for at least thirty minutes three times a week, May found that fetuses show the same beneficial effects of cardiovascular training as do their physically…
Williamson’s wise advice went unheeded. In the years after her study was published in 1978, ultrasound became increasingly available in Singapore and other countries in South and East Asia. The introduction of this technology enabled a new and brutal form of sex selection: if the sonogram shows it’s a girl, abort…
A stress-related decline in the sex ratio is no anomaly, but a biological mechanism that evolved to keep the species going, according to Ralph Catalano, professor of public health at the University of California, Berkeley. “From an evolutionary perspective, in stressful eras it’s a smarter bet to have a female child…
There’s no doubt that seeing one’s future child on an ultrasound monitor is a powerful experience, the first visual evidence of the fetus in a culture in which seeing is believing. The encounter can be so compelling, in fact, that some medical providers are using it not just as a diagnostic tool, but as a treatment in…
“During most of pregnancy, the placenta separating mother and fetus is only one cell thick,” Koren tells me. “But it has an array of mechanisms to help it do its job of protecting the fetus.” These subcellular tools, he explains, include tiny pumps that expel toxins before they can do any damage, immune agents that…
Williams’s experiments have shown that the offspring of mice who ingest a phytochemical derived from cruciferous vegetables like broccoli, cabbage, and brussels sprouts during pregnancy were much less likely to get cancer, even when exposed to a known carcinogen. The same is true of the offspring of mice who were…
I don't know how other prospective fathers treat their wives' pregnancies, but I saw it as a science project. It had a protocol, parameters, a timeline, and even the one item that makes funding agencies happy: a deliverable. I found myself poking at my wife's abdomen, asking, "Who's Daddy's little gestating…
Very frequently I hear or read of my artifacts adjudged by critics as being "failures," because I did not get them into mass-production and "make money with them." Such money-making-as-criteria-of-success critics do not realize that money-making was never my goal. I learned very early and painfully that you have to…
Twenty-six years ago I noticed that our clearheaded, undrugged mothers, who were not strapped down or restrained in any way, eagerly, with mothedy murmurs of joy, reached out to grasp and hold their babies as I placed them on their abdomens. Why not let them hold their babies? I have heard many absurd objections over…
What are other benefits of breast-feeding? Let's consider a few. We think the Creator intended that your wife should not have an immediate return of her menstrual bleeding after having a baby. She has donated blood to the baby itself (not directly but via the ingredients), and she then loses some incident to its…
What, then, is the difference between human and other animals? Are their bodies made differently? As a matter of fact they are remarkably similar. Cat and dog bodies are used in premedical anatomy studies due to the similarity of structures with identical name and function. Is it that they just can't experience pain?…
After the baby is born, most doctors, including myself, hold it in our lap momentarily, to allow baby blood in the placenta to pass by gravity through the umbilical cord back into the baby, and to wipe the baby as clean as possible with gauze squares. We feel this is a substitute for the animal mother's licking her…
In healthy, normal mothers with healthy, normal babies there is no such thing as overdue. This term carries a dire connotation that unjustly scares the daylights out of uninformed people. More women have been unnecessarily forced into long, hard, unprepared labor, more b babies damaged by being made to come through a…
Now, back to the family cat or dog in labor. By quietly, even sneakily, approaching we observe additional factors involved. 1. The need for darkness and solitude. Bright lights are indeed disturbing. My attempts to take photographs of dogs and cats have been foiled by the indignant laboring mothers retreating to dark…
Animals in second-stage labor, then, act, look, and breathe as though they are having a bowel movement. So what should your wife do after her cervix is completely open and the baby begins to slip through? She should do the same thing. Now, here again, we run into the minor structural differences between humans and…
I do not know why the Creator unaesthetically put the baby door in this particular location—between the bladder and the rectum. It has necessitated a very unladylike but definitely mother-like position known as squatting to perform the act of giving birth. Whether we like it or not, the act of emptying the baby box is…
In its encounter with Nature, science invariably elicits a sense of reverence and awe. The very act of understanding is a celebration of joining, merging, even if on a very modest scale, with the magnificence of the Cosmos. And the cumulative worldwide build-up of knowledge over time converts science into something…
Low was looking to explain why young women have fat on their breasts and buttocks more than on other parts of their bodies. The reason this requires explaining is that young women are different from other human beings in this respect. Older women, young girls, and men of all ages gain fat on their torsos and limbs…
