The early childhood stage is from second to fifth year of life while late childhood at age from sixth year till the onset of puberty. The sex external organs are present at birth but remain dormant without any significant change till puberty. Because of the presence of high level of female sex hormones particularly in the later stage of intrauterine life, the neonate baby of both genders may have enlarged breasts and secrete milk called witch’s milk from second to fourth day. Also, female neonate may have vaginal bleeding from second to fifth day of life. These maternal sex hormones disappear within a week after birth. The prepuce becomes retractable by three years of age in most male children. The biological growth of sex organs is very slow during the whole childhood.

The sex cells as sperms and ova become mature and are regularly produced. Menarche or onset of menstruation takes place at about 13 years of age in girls.

Adolescence is the age from the end of puberty to complete adulthood and signifies the period of final sexual maturation. Adolescence is from 15 to 18 years in girls and 17 to 20 years an boys. Adulthood or youth is a period of active sexuality. Man is maximum youth at 25 years and woman at 20 years of age. Early youth is from 18 to 30 years in frigidity in woman and from 20 to 35 years in man. Late youth is from 30 to 40 years in woman and from 35 to 45 years in man. Middle age is from 40 to 60 years in woman and from 45 to 65 years in man. Middle age is marked by climacteric in both the genders which is a period of change from active law and sex life to its end. Menopause or cessation of menstruation occurs at about 47 years of age in a woman. Man loses his capacity to reproduce by 70 years of age while a woman loses it at 50 years of age.
