Castration anxiety is the central concept of personality. It is related to the concept of psychoanalysis. Castration is more linked with the concept of the Oedipus complex.
Sigmund Freud was the first person who has been proposed this concept. Castration is nothing but only the fear and anxiety about the castration of the genital organ.
It is a childhood experience that occurs between the age of 3 to 5 years. It is also called an unconscious experience that occurs again and again with all individuals in their childhood.
Thus the little boy fears that their father would castrate his genital organ for the forbidden sexual aggressive impulse that leads to the castration anxiety.
By looking through the perspective of public health, we should focus on the healthy and hygiene conditions of the public but not a single individual as the whole society is more important.
If we divert our attention and resources towards an individual then the public will be neglected and it will create a lot of problems for the whole of society and that specific individual can face problem due to the overall bad conditions of health.
