Study Notes

Breast Development in Females

  • M1: Tanner 1 - Nipple is raised above the breast level, similar to a child.
  • M2: Tanner 2 - Budding stage, areola increased in diameter, and surrounding area slightly elevated.
  • M3: Tanner 3 - Breast and areola enlarged, no contour separation.
  • M4: Tanner 4 - Increasing fat deposits, areola forms a secondary elevation above the breast.
  • M5: Tanner 5 - Adult stage, areola part of general breast contour, strongly pigmented, and nipple projects.

Penis and Testes Development in Males

  • G1: Tanner 1 - Testes, scrotum, and penis are the same size and shape as in a young child.
  • G2: Tanner 2 - Enlargement of scrotum and testes, skin of scrotum becomes redder, thinner, and wrinkled.
  • G3: Tanner 3 - Enlargement of the penis, especially in length, and further enlargement of testes.
  • G4: Tanner 4 - Continued enlargement of the penis and sculpturing of the glans, increased pigmentation of scrotum.
  • G5: Tanner 5 - Adult stage, scrotum ample, and penis reaching nearly to the bottom of the scrotum.

Pubic Hair Development in Females

  • P1: Tanner 1 - No growth of pubic hair.
  • P2: Tanner 2 - Initial, scarcely pigmented straight hair, especially along the medial border of the labia.
  • P3: Tanner 3 - Sparse, dark, visibly pigmented, curly pubic hair on labia.
  • P4: Tanner 4 - Hair coarse and curly, abundant but less than adult.
  • P5: Tanner 5 - Lateral spreading, type and triangle spread of adult hair to the medial surface of thighs.
  • P6: Tanner 6 - Further extension laterally, upward, or dispersed (occurs in only 10% of women).

Growth and Nutrition

  • Delayed onset of puberty is a normal variant in both males and females, or may be a consequence of using puberty blockers in transgender and gender-diverse youth.
  • It is usually accompanied by a lag of stature growth.
  • Parent or sibling may have had a similar adolescent growth pattern.
  • Once pubertal changes begin, the sequence of development is the same as for other adolescents, but it may occur over a different time span.

Pregnancy

  • Calculate weight gain during pregnancy from the patient's prepregnancy weight.
  • Determine the prepregnancy BMI to guide weight gain during pregnancy.
  • Monitor the patient's weight throughout pregnancy using the BMI weight gain curve guidelines.
  • Recommended weight gain during pregnancy is based on the patient's prepregnancy BMI:
    • 11.5 to 16 kg (25 to 35 lb) for patients with a prepregnancy BMI of 19.8 to 26.0.
    • 5 to 9.1 kg (11 to 20 lb) for underweight patients (BMI 29).
  • Adjust the recommended weight gain for patients with a twin or triplet pregnancy.
  • Obese patients are at increased risk of complications during pregnancy.

Older Adults

  • Measurement procedures for older adults are the same as those used for other adults.
  • Calculate the BMI to identify any problems with underweight.
  • Identify any associated health conditions or food insecurity.

Abnormalities

  • Acromegaly: a rare disease of excessive growth and distorted proportions caused by hypersecretion of growth hormone and insulin-like growth factor after closure of the epiphyses.
  • Caused by a benign pituitary adenoma or other rare tumor, or familial syndromes.
  • Growth hormone excess leads to slow skeletal growth and soft tissue enlargement.

Puberty Blockers

  • Gonadotropin-releasing hormone (GnRH) analogs are a synthetic form of the human body's GnRH hormone.
  • Suppress the secretion of LH and FSH, which ultimately suppress the body's release of sex hormones, including testosterone and estrogen, during puberty.
  • Delay changes in both primary and secondary sex characteristics that can affect gender expression.
  • Do not cause permanent changes in an adolescent's body.

Test your knowledge on the Tanner stages of breast development, focusing on the physical changes that occur during puberty. Questions may cover the characteristics of each stage and the sequence of development.
