That there are annual seasonal changes in the human organism, especially 

connected with the sexual function, is a statement that has been made by 

physiologists and others from time to time, and the statement has even 

reached the poets, who have frequently declared that spring is the season 

of love. 

 

Thus, sixty years ago, Laycock, an acute pioneer in the 

investigation of the working of the human organism, brought 

together (in a chapter on "The Periodic Movements in the 

Reproductive Organs of Woman," in his _Nervous Diseases of 

Women_, 1840, pp. 61-70) much interesting evidence to show that 

the system undergoes changes about the vernal and autumnal 

equinoxes, and that these changes are largely sexual. 

 

Edward Smith, also a notable pioneer in this field of human 

periodicity, and, indeed, the first to make definite observations 

on a number of points bearing on it, sums up, in his remarkable 

book, _Health and Disease as Influenced by Daily, Seasonal, and 

Other Cyclical Changes in the Human System_ (1861), to the effect 

that season is a more powerful influence on the system than 

temperature or atmospheric pressure; "in the early and middle 

parts of spring every function of the body is in its highest 

degree of efficiency," while autumn is "essentially a period of 

change from the minimum toward the maximum of vital conditions." 

He found that in April and May most carbonic acid is evolved, 

there being then a progressive diminution to September, and then 

a progressive increase; the respiratory rate also fell from a 

maximum in April to a minimum maintained at exactly the same 

level throughout August, September, October, and November; 

spring was found to be the season of maximum, autumn of minimum, 

muscular power; sensibility to tactile and temperature 

impressions was also greater in spring. 

 

Kulischer, studying the sexual customs of various human races, 

concluded that in primitive times, only at two special 

seasons--at spring and in harvest-time--did pairing take place; 

and that, when pairing ceased to be strictly confined to these 

periods, its symbolical representation was still so confined, 

even among the civilized nations of Europe. He further argued 

that the physiological impulse was only felt at these periods. 

(Kulischer, "Die geschlechtliche Zuchtwahl bei den Menschen in 

der Urzeit," _Zeitschrift fuer Ethnologie_, 1876, pp. 152 and 

157.) Cohnstein ("Ueber Praedilectionszeiten bei Schwangerschaft," 

_Archiv fuer Gynaekologie_, 1879) also suggested that women 

sometimes only conceive at certain periods of the year.
