Re: circumcision and birth rate
Circumcision Status and Fertility of Men
The British in World War II said that the American men were over-sexed and over here. The Korean War Generation were pretty much the same, being the Little Brothers of the World War II men.
I remember Korean War Age men (born from about 1927 to 1934) in a Texas college in the early fifties talking about their multi-ogasms.
Remember that the Edward O. Laumann data on the American circumcision rate in history shows that only about one third of the age group born from about 1927 to 1934 were circumcised, though his data begins in 1932 or 1933. And in certain states and regions of states a much larger percentage of male babies were born at home rather than in hospitals and so they were not circumcised.
Hospitals seemed to demand more control over patients than did the country doctors who helped in births at home for so many years. And hospitals were centers of control from the top down in the medical profession, meaning that the Medical Eugenics Movement was going strong in the Hospitals. Circumcision was one program of the eugenics movement, and ultimately had, among its purposes, that of reducing the birth rate.
"Prevalence of Circumcision Since the age range of males participating in the NHSLS was 18 to 59 years, estimates of the prevalence of neonatal circumcision can be calculated for the years 1933 to 1974. As shown in the Figure, the steady increase in circumcision rates among respondents during much of this period reflects the increase identified by other investigators. The proportion of newborns that were circumcised reached 80 percent in the years after World War II and c1imaxed in the mid 1960s. This rise mirrors the increasing prevalence of hospital births."
The idea that one reason why more American males of the Korean War Age Group were able to have more than one sexual c1imax in a short period was because most of them were not circumcised is a kind of taboo hypothesis. There were overall health and sociological factors going on in the generations, so that circumcision status may have been only one reason for greater sexual abilities, but not the sole reason.
It is true that the Traditionalist Generation of men were not subject to estrogen mimickers and social movements which tended to reduce male sexual abilities, as were the Baby Boomers and the younger generations following them.
The researchers who have done studies on multiple male ogasms, who are likely Baby Boomers or Generation X people, assumed that the Male Refractory Period is absolute for a period of time and that it is unusual and perhaps abnormal to recover from that refractory period while its biochemistry is in effect.
That period of time of the assumed Male Refractory Period is at least fifteen to thirty minutes.
The belief among the experts seems to be that women do not have such a refractory period driven by biochemistry as do males. The opinion seems to be that women who are able to ogasm can have multiple ogasms.
The truth, probably, is that a larger percentage of males of what is called the Traditionalist Generation, born from 1900 to 1945, did not have such an absolute refractory period, though it did exist for many, and at times for those who were sometimes multi-ogasmic.
There are differences between the birth rate for men of the Korean War Age Group compared to the birth rate of men of the Baby Boomer and Generation X Age Group. The Korean War men fathered more children than the Baby Boomers or Generation X males. There might be a correlation or even a cause and effect here. I have not searched for birth rates of the various U.S. generations of the 20th century.
But the birth rate in the U.S. per 1,000 population was about 18 in the early thirties, about 26 in 1947-1948 and about 14 in 2009. The large rise in birth rate from 1945 to 1948 is due largely to the large numbers of children of the World War II Generation and that movement down from the peak birth rate of 1948 was slowed by the large number of children the Korean War Age group men fathered in the late fifties and early sixties. The Traditionalist Generation - born 1900 to 1945 - as a whole was a fertile American Generation.
