LESSON IX 

 

THE DETERMINATION OF SEX 

 

 

The term "The Determination of Sex" is employed in two general senses in 

scientific circles. 

 

The first usage is that of the biologist, and it includes within its 

scope merely the discovery and understanding of the CAUSES which 

determine whether the embryo shall develop into a male or into a female. 

In the discussion of the subject from this standpoint there is but 

little, if any, attention given to the question of whether the sex of 

the unborn child may be determined by methods under the control of man. 

The biologist simply studies the causes which seem to lead to the 

production of an individual of one or the other sex, without regard to 

whether these causes, when discovered, may or may not be amendable to 

human control. 

 

An authority, speaking of this standpoint concerning the question 

referred to, says: "We may discover the causes of storms or earthquakes, 

and when our knowledge of them is sufficiently advanced we may be able 

to predict them as successfully as astronomers predict eclipses, but 

there is little hope that we shall ever be able to control them. So it 

may be with sex; a complete understanding of the causes which determine 

it may not necessarily give us the power of producing one or the other 

sex at will, or even of predicting the sex in any given case. Whether we 

shall ever be able to influence the causes of sex-determination cannot 

as yet be foretold; at present, biologists are engaged in the less 

practical, but immensely interesting, problem, of discovering what those 

causes are." 

 

The second usage of the term, includes and embraces the idea of the 

voluntary determination or control of the sex of the future child, by 

means of certain methods or certain systems of treatment, etc. Of recent 

years, science has been devoting considerable attention to the question 

of whether or not man may not be able to produce any particular sex at 

will, by means of certain systems or methods of procedure. Many theories 

have been evolved, and many plans and methods have been advocated, often 

with the expenditure of much energy and enthusiasm on the part of the 

promulgators and their adherents. 

 

In this lesson there will be briefly presented to you the general 

consensus of modern thought on the subject, with a general outline of 

the favorite methods and systems advocated by the several schools of 

thought concerned in the investigation. 

 

Professor Doncaster, the well-known authority on the subject, says: "But 

little progress has been made in the direction of predicting the sex of
