In the case of the female there are no reactions that can be 

 considered male or female after the ovaries have been removed. 

 In the normal female there are few elements in its behavior that 

 are characteristically female with the exception of the reactions 

 during the period of heat, or the reactions to its own young. 



OBSERVATIONS OF EXPERIMENTS 



A. Males with ovary grafts 



Male 39 A, born April 24, 1918. May 11th testicles removed, two 

 pieces of ovary transplanted subcutaneously on abdominal wall. Feb- 

 ruary 15, 1919, killed. No testis tissue present. Sperm sacs long, 

 but slender, not distended. 



About one month after the transplantation of the pieces of the 

 ovary, the teats of the mammary glands began to be noticeably 

 increased in size and continued to increase until they reached the 

 size of a pregnant female near term. The animal was confined 

 alone in its cage until there was no doubt that the ovarian grafts 

 had persisted and that the mammary glands resembled distinctly 

 those of a normal female. Observations on the behavior of the 

 animal were begun and continued over a period of some months, 

 being conducted daily at some periods and intermittently at 

 other times when the animal had remained alone for a period of 

 about a week. The following observations will serve to represent 

 the behavior of the animal for a period of three months : 



November 2nd (five months after operation). At this time the 

 teats of the mammary glands are at the height of their development, 

 being as large as those of a pregnant female. Ovarian grafts on ab- 

 dominal wall easily palpated. Young guinea-pigs placed in the cage, 

 but upon attempting to suckle, the male fights them away and ex- 

 hibits no sign of female psychical tendencies. When mother of young 

 placed in cage, male follows her continuously, uttering male sex call 

 and reacts so typically male-like that even copulation is attempted. 

 When normal male is placed in cage with castrated male bearing ovaries 

 a fight follows almost immediately. 



November 7th. Female in heat placed in cage; the animal reacts 

 as does a normal male though somewhat less vigorously. 



November 11th. Another female in heat introduced into cage; 

 same results as above; the animal utters the characteristic male call 

 and attempts to imitate the functional male.
