SCIENS & LIFE, 2003, # 11.



1. In December of 2001 was published the book by Vladimir Iskrin titled The Dialectics of Sexes (published by Б&К, St. Petersburg, Russia – 208 pages, planned circulation 10,000).


From the first days on the market it has aroused a big interest in readers: both specialists (biologists, psychologists, physicians, sexologists, philosophers) and non-specialists. After an interview for the radio Liberty (March 5, 2002) Vladimir Iskrin was invited to take part in the program Freedom of Speech at NTV channel, that is one of the high rate channels in Russia (March 7, 2002).


The first evaluations as well as a very high demand make us think of it as of a scientific bestseller compared with A Brief History of Time by Steven Hawking.

Meanwhile this book has a very clear and understandable language. Written in a popular manner, sometimes a dialogue with the reader, it can be characterized as popular scientific.


There is no doubt it will be met outside Russia with not less interest. The author’s approach to the problems unsolved during decades is new and convincing, extremely well-grounded. The book is likely to have a long future.


The Academic Council of Medical and Social Management Academy and Vladimir Iskrin place on this web-page a detailed description of The Dialectics of Sexes, so that everyone who works in this field could get the idea. As well it is an offer for the publishers and universities to publish it in English and other European languages.



2. In The Dialectics of Sexes the author finds the solution for the problem of so called sexual phenomena. Among them is the war phenomenon. It is known that in the years of wars the amount of newborn males is bigger. And the longer a war lasts, the more boys are born, statistics says the proportion has reached 109:100 compared to the normal of 105:100. During the recent decades this phenomenon was explained in different ways, however none had theoretical scientific explanation. Iskrin manages to solve this enigma within a completed theory that involves biological, sociological and historical knowledge.

With the help of this theory Iskrin reveals the reasons of ALL the abnormal sexual proportions registered. He explains:

– why in the USA, Canada and some countries of Western Europe less boys are born compared to few decades ago;

– why in the US black population, on the contrary, more and more boys are born;

– why men suffering from different diseases (radiation illness, cardiovascular diseases, cancer, diabetes, etc.) have more sons than daughters;

– why young people are more likely to have a son;

– why there are more males among the first children born to mothers;

– why fathers who have had a long sexual abstention have more daughters;

– why among kids born to single mothers there are more girls than in complete families;

– why girls prevail among prematurely born babies;

– why the number of new born girls is two times as big as that of boys to the mothers who have had a severe stress or a chemical contamination during pregnancy.



3. Looking at sex as a biological category, Iskrin applies the laws discovered in his research to dioecious animals and plants. He explains, for instance, the change of sex that takes place in the vegetable life (described by Menninger in Fantastic Trees, New York, 1967). This phenomenon was never explained before!

Also The Dialectics of Sexes finds out what natural law determines the choice of sex made by embryos of Mississippian alligators according to the temperature. Only males are hatched from eggs that have been developing at the temperature above 34° C, and only females are hatched from eggs kept at below 30° C. Why does nature use this mechanism? The readers will find the answer.



4. On his way of interpreting sexual phenomena the author comes across the questions that on the surface have nothing to do with sexes. But it turns out that within the theory of sexes one can explain why there is such a tendency as acceleration. Also the scientific audience as well curious readers will see why the primitive society was exogamous. These problems are solved for the first time ever.



5. Iskrin uses historical approach to sexes and sexual relations. Readers will for the first time find answers for the following questions:

– why two sexes appeared at a certain stage of natural history;

– which of the sexes is logically primary;

– which stage in human history is more beneficial for self realization for each sex;

– why Muslims are allowed to have four wives, and not more than that;

– what is the origin of dowry and its contrary hope-chest;

– what is the tendency in the modern relations between sexes;

– what is to happen to love and romance in the future;

– why the heterosexual form of reproduction is supposed to be changed by the other form of a higher level.



6. Theory and practice come together in every chapter. The author takes statistics and well known facts from human experience. Together with the reader the author discusses particular problems that appear between men and women.

Coming to the practical field of sexual interaction Iskrin gives the complete list of conditions that statistically determine the sex of the baby. I have to say Iskrin’s book is the first one to bring together all the factors.



7. This book is a result of almost 30 years of research. It contains several tens of scientific discoveries and some of them I have mentioned above.

Still despite the importance of these pioneer revelations they are just the above-water part of an iceberg. The underwater part is a wholesome general conception. Iskrin created the Theory of Sexes. Only this wholesome theory makes possible to answer all the questions scientists could not answer for a long time.

I believe The Theory of Sexes would be a better title for the book in English.

Making this theory Iskrin continues the tradition started by the prominent soviet researcher of this area V. A. Geodakyan. Unfortunately, Geodakyan’s works did not become well known in the West. The more it seems that Iskrin’s book will be a long-awaited theoretical key for the scientists in Europe and America who are searching the explanation for the above-water sexual phenomena.



8. Let me here enumerate the crucial points of the theory created by Iskrin (of course I am limited to a brief summary):

– Males are more diverse than females.

– That is why women are to choose a sexual/matrimonial partner from a wider range.

– Females par excellence are the choosing and passive side, while males are the side that actively offers itself.


– Choosing her sexual/matrimonial partner a woman selects biological and social traits that are objectively required by the changing environment. These features are genetically and socially embodied in her children.

– Women are relatively more farsighted, while men are momentary. Men are more interested in the process of sexual intercourse, and women are aimed at its result.

– Thus aimed at the quality (compatibility with the environment) of her kids a woman supplies to the future a certain number of them; a man, whose goal is to copy himself in a more number of kids, is a provider of his particular individual quality.


– Endowing males with a very wide range of features (making the male sex very diverse) nature is blindly searching the ways of historical progress.

– Through the male sex (due to the changing environment) necessary changes of a species are introduced.

– The male sex turns out to be the revolutionary side of a species, while the female sex is its conservative side.


– However comprising the revolutionary trend at the level of a species (in biology – variability) males on the individual level are conservative. Females bearing the tendency of conservatism (in biology – fastness) on the individual level are more flexible and subject to changes.

– The mentality of both sexes is hard to understand ignoring this fundamental difference.

– The differences of male and female mentality take place in the practical fields where both sexes find their vocations.


– As experimental material of nature the male sex is produced with a certain surplus (under normal conditions for 100 girls 105 boys are born, and before that for 100 female zygotes conceived there are 120-180 male ones).

– In case of deterioration of the conditions male mortality as well as male birth rate increases (in philosophical terms, rotation of features increases).

– This is how a species adapts itself to new conditions of life, corrects its historical development trying new features on males.


– The first six phenomena that I have spoken about in (2.) are caused by the weakening or increasing rotation (according to improving or worsening conditions).

– The seventh phenomenon (superfluous birth of girls after too long abstention of fathers) is the response of the male sex to the catastrophic changes, the signal of which is the absence of the females.

– The three last phenomena in the list are attributed to female sex and are explained in the book by the more or less difficult conditions inside the womb during pregnancy. The male fetuses (that are nature’s experimental material) turn out to be less viable and subject to death as well as before birth.



9. The book consists of 15 chapters:

10. Here I submit a brief biography of Vladimir Ivanovich Iskrin.


He was born in 1948 in Leningrad. Graduated from Leningrad State University and has degrees in history (1977), political science (1995) and psychology (1998).  His scientific research includes such fields as cosmology, theory of history, psychology, and ecology. Iskrin is the author of several books. Among these is New Psychology (published 1998, second edition 2001).

Iskrin coordinates the research department of new psychology at Medical and Social Management Academy of St. Petersburg. Also he gives lectures at St. Petersburg State Technical University.



11. There is as well a web version of The Theory of Sexes. It is located at Here you can find the complete text of the book and also tables and diagrams.



We are ready to thoroughly consider all the offers on publishing the book in English and other languages.
