Puberty and Adolescence

A

Adolescent Sexuality

Adolescent sexuality refers to the physical, emotional, and social changes that occur during puberty and adolescence, including the development of sexual feelings, attractions, and behaviors. This period typically spans from early childhood to young adulthood (around 10-25 years old), during which individuals begin to explore their own identities, relationships, and sexual expression.

Adrenarche

Adrenarche refers to the early onset of puberty-related physical changes in children, typically between the ages of 6 and 9, caused by the activation of the adrenal glands. These changes can include increased body hair growth, oiliness of the skin, and other signs that signal the start of puberty, often before the more obvious physical developments associated with sex hormone-driven puberty.

B

Breast Development

Breast development, also known as thelarche, is the process of breast growth and maturation that typically occurs during puberty in individuals assigned female at birth. It's one of the first visible signs of puberty and is triggered by hormonal changes, primarily an increase in estrogen. The process usually begins between ages 8 and 13 and can continue into the late teens or early twenties.

D

Deepening-of-voice

Deepening-of-voice refers to the process where an individual's voice becomes lower in pitch, typically occurring during puberty in males. This change is primarily caused by the growth and enlargement of the larynx (voice box) and vocal cords due to increased testosterone levels. The deepening of voice is considered a secondary sex characteristic and is one of the notable signs of male pubertal development.

Delayed Puberty

Delayed puberty refers to a condition where an individual experiences the onset of puberty later than the typical age range. In general, puberty is considered delayed if there are no signs of sexual development by age 14 in boys or age 13 in girls. This delay can affect the development of secondary sex characteristics, growth spurts, and reproductive maturation.

M

Menarche

Menarche is the term used to describe a person's first menstrual period. It's a significant milestone in female puberty, marking the beginning of reproductive capability. Typically occurring between the ages of 10 and 15, menarche signals that the body has started releasing eggs and is physically capable of becoming pregnant.

N

Nocturnal Emissions

Nocturnal emissions, commonly known as "wet dreams," are involuntary ejaculations that occur during sleep, typically accompanied by erotic dreams. This natural phenomenon is most common in adolescent males and young adult men, though it can happen at any age. Nocturnal emissions are a normal part of male sexual development and do not indicate any health issues.

P

Precocious Puberty

Precocious puberty refers to the onset of puberty at an unusually early age, typically before age 8 in girls and before age 9 in boys. This condition is characterized by the early development of secondary sexual characteristics, such as breast growth in girls or testicular enlargement in boys, as well as accelerated growth and bone maturation.

Pubarche

Pubarche refers to the first appearance of pubic hair during puberty. It's one of the earliest visible signs of sexual maturation and typically occurs between the ages of 8 and 13 in girls and 9 and 14 in boys. Pubarche is caused by an increase in androgen hormones, primarily from the adrenal glands.

Puberty Blockers

Puberty blockers, also known as puberty inhibitors, are medications used to pause the physical changes associated with puberty. These drugs work by suppressing the release of sex hormones, effectively delaying the development of secondary sex characteristics. Puberty blockers are primarily used for transgender and gender non-conforming youth who experience gender dysphoria, allowing them more time to explore their gender identity without the stress of unwanted physical changes.

Puberty

Puberty is the period of human development during which a child's body matures into an adult body capable of sexual reproduction. It is a complex process involving significant physical, hormonal, and emotional changes. Puberty typically begins between ages 8 and 14, although the timing varies among individuals.

S

Spermarche

Spermarche refers to the onset of sperm production in males, typically occurring during puberty. It marks the beginning of a male's ability to produce viable sperm and, consequently, the potential for biological fatherhood. This milestone usually happens between the ages of 11 and 15, though the exact timing can vary widely among individuals.

T

Tanner Stages

Tanner stages, also known as the Sexual Maturity Rating (SMR) system, is a scale used to measure the physical development of children, adolescents, and adults during puberty. Developed by British pediatrician James Tanner, this system categorizes the progression of physical changes in both male and female bodies through five distinct stages, from pre-pubescent (Stage 1) to fully mature adult (Stage 5).

Thelarche

Thelarche refers to the onset of breast development in females, typically marking the beginning of puberty. It's characterized by the appearance of breast buds, which are small, firm mounds of tissue beneath the nipple and areola. Thelarche usually occurs between the ages of 8 and 13, though this can vary among individuals and populations.

W

Widening of Hips

Widening of hips refers to the natural expansion of the pelvic region that typically occurs in females during puberty and continues into early adulthood. This process is primarily driven by hormonal changes, particularly the increase in estrogen levels, which stimulates the growth and reshaping of the pelvic bones and surrounding tissues.
