    Serum prolactin and estrogen levels remained stable in boys aged 8-15. In girls, these hormone levels were similar to boys until age 13, then increased at ages 14-15.

    Area of Science:

    • Pediatric endocrinology
    • Reproductive health
    • Human growth and development

    Background:

    • Hormonal changes during puberty are critical for development.
    • Prolactin (PRL) and estrogen play roles in adolescent physiology.
    • Understanding age-related hormonal shifts in children is essential.

    Purpose of the Study:

    • To investigate age-related changes in serum prolactin and total estrogen levels in boys and girls.
    • To compare hormonal profiles between sexes during prepubertal and pubertal stages.
    • To establish normative data for these hormones during childhood and adolescence.

    Main Methods:

    • Serum samples were collected from boys and girls aged 8 to 15 years.
    • Concentrations of prolactin (PRL) and total estrogen were measured.

  • Data were analyzed to assess changes with age and differences between sexes.

    • Main Results:

    • Boys showed no significant change in PRL with age; levels were comparable to adult males.
    • Girls aged 8-13 had similar mean PRL and estrogen levels to boys of the same age.
    • A significant increase in PRL and estrogen levels was observed in girls aged 14 and 15.

    Conclusions:

    • Serum prolactin and estrogen levels exhibit distinct patterns in adolescent girls compared to boys.
    • Hormonal changes in girls accelerate around ages 14-15, indicating pubertal progression.
    • These findings contribute to understanding normal endocrine development during puberty.
