Puberty.
Dr. Sayeed Ahmad D.
I. Hom. (London)

Puberty is the most obvious sign that an individual
has entered adolescence. Technically, puberty refers to the period
during which the individual becomes capable of sexual reproduction. More
broadly, however, puberty is used as a collective term for all the
physical changes that occur in a growing girl or boy as the individual
passes from childhood to adulthood.

The physical changes of adolescence are triggered by
hormones (chemical substances in the body) that act on specific organs
and tissues. In boys, a major change is increased production of the
hormone testosterone, while girls experience increased production of the
hormones called estrogens. In both sexes, a rise in growth hormone
produces a growth spurt. During this spurt, which lasts two or more
years, an individual commonly grows 2 to 4 inches (5 to 10 centimeters)
taller per year.

Sexual development. Many of the most dramatic changes
of puberty involve sexual development. Internally, adolescents become
capable of sexual reproduction. Externally, as secondary sexual
characteristics appear, girls and boys begin to look more like mature
women and men. The term secondary sexual characteristics refers to a
variety of physical traits, such as body shape, voice, and facial hair.

Not everyone goes through puberty at the same time or
rate. In Western industrialized societies today, the adolescent growth
spurt occurs, on average, between the ages of 12 and 14 in boys, and 10
and 12 in girls. But some young people start puberty when they are 8 or
9, and others not until they are in their mid-teens. Generally, girls
begin puberty about two years earlier than boys. The duration of puberty
also varies greatly, from 11/2 to 6 years in girls and from 2 to 5 years
in boys.

Disorders of Puberty

Amenorrhea

Amenorrhea, the absence of menstrual periods. It is
called

primary
amenorrhea if
it occurs at puberty, when a girl normally begins menstruating. Secondary
amenorrhea refers to the lack of
menstrual periods in women who have previously menstruated. Amenorrhea
is normal in pre-pubescent girls and in women who have ceased
menstruation due to pregnancy, breastfeeding, or menopause.

Any healthy girl who has not had a period by the time
she is 16 years old has primary amenorrhea. Primary amenorrhea may be
caused by the delayed onset of puberty. It also may be linked to
infertility caused by Turner’s Syndrome, a genetic disorder that
prevents sexual maturing in girls. Some cases of amenorrhea are
associated with birth defects that cause the vagina or uterus to develop
improperly.

Secondary amenorrhea may result from a variety of
factors. It sometimes occurs for the first few months after a woman has
stopped taking birth-control pills. This type is called postpill
amenorrhea. Secondary amenorrhea also may be caused by intensive
physical exercise, including long-distance running or ballet dancing;
extreme weight loss; disorders of the endocrine system (such as tumors
of the pituitary gland), and various disorders of the ovaries. An
ovarian disorder called polycystic ovary syndrome, or Stein-Leventhal
syndrome, is characterized by an extremely irregular menstrual cycle in
which ovulation may not occur. This disorder usually involves
infertility, but treatment can help make the periods more regular.

Amenorrhea is often caused by psychological factors.
Increased stress brought on by such major life events as losing a
partner or loss or change of occupation can upset the normal menstrual
cycle for a few months or longer. Increased stress can cause hormonal
changes, such as raised levels of cortisol and prolactin, which affect
menstruation. Periods normally return after the stress subsides.

Treatment of amenorrhea is determined by its cause.

Turner Syndrome

Turner Syndrome, relatively common genetic disorder
that causes abnormal growth development and infertility in females.
Turner syndrome is characterized by certain physical features, including
short stature, loose folds of skin on the neck, a small jaw, and a
higher incidence of heart, kidney, and thyroid problems. Some
individuals with the disease experience learning difficulties.

Turner Syndrome occurs in about 1 out of every 2,000
live female births. Girls with the disorder do not develop secondary
sexual characteristics, the body changes, such as breast
development, that occur during puberty. They typically have
underdeveloped ovaries, which prevents the onset of menstruation and
also contributes to infertility later in life.

Turner syndrome is caused by a partially or
completely missing sex chromosome. Chromosomes are gene-carrying
structures found within the nuclei of cells. In the human body, all
cells except for sperm and egg cells contain 46 chromosomes arranged in
23 pairs. Of these, 22 of the pairs each consist of chromosomes that are
almost identical, while the 23rd pair contains special chromosomes that
determine the sex of the individual. The sex chromosome pair in healthy
males contains an X and a Y chromosome, while the sex chromosome pair in
females contains two X chromosomes. In a female born with Turner
syndrome, part or all of one X chromosome in her sex chromosome pair is
absent. Scientists do not know what causes this chromosomal abnormality—it
apparently occurs randomly and is not linked to factors known to
increase the risk of a birth defect, such as a pregnant woman’s
exposure to drugs, radiation, or disease-causing viruses or bacteria.

Harmones in Puberty

Androgen

Androgen, term embracing any of the male sex
hormones, substances that induce and maintain secondary sex
characteristics in males. The principal androgen is testosterone,
produced in the testes of males and in the adrenal glands of both sexes.
Testosterone circulates in the blood and is excreted in the urine.
Androgens function principally, beginning at puberty, in the stimulation
of such male secondary sex characteristics as development of the genital
organs and maturation of sperm, growth of body hair, and changes in the
larynx that lower the voice. Androgens have an anabolic effect—that
is, they stimulate protein synthesis and inhibit protein breakdown,
enhancing the growth of muscle and bone tissue in the developing male.
An excess of androgens can lead to a variety of disorders, including the
accentuation of male secondary sex characteristics in both males and
females. Less frequently, an excess of androgens may cause testicular or
ovarian tumors.

Estrogen

Estrogen, any of a group of female sex hormones that
stimulate the appearance of secondary female sex characteristics in
girls at puberty. Estrogens control growth of the lining of the uterus
during the first part of the menstrual cycle, cause changes in the
breast during pregnancy, and regulate various metabolic processes. Among
the better known estrogens are estrone, ethinyl estradiol, and estriol,
all produced primarily in the ovaries. Stilbestrol and ethinyl
estradiol, two synthetic estrogens, are respectively five and ten times
as potent as estrone; their activity is similar to that of natural
estrogens. They are used to treat various conditions, including estrogen
deficiencies in women (most commonly after menopause) and inflammation
of the vagina. They may be used to stimulate lactation following
childbirth and in the treatment, but not cure, of advanced and even
disseminated cancer of the prostate gland in men.

Research has shown that when estrogen is administered
as a post-menopausal hormone-replacement therapy, recipients experience
a significant decrease in bone fractures. However, questions remain
regarding the safety of estrogen in hormone-replacement therapy.
Possible risks include breast or uterine cancer or cardiovascular
disease.

Pineal Body

In humans the structure develops until the seventh
year, when it is slightly larger than a pea; thereafter, throughout
life, small mineral particles, particularly calcium, may be deposited in
the pineal body. The mineral deposits can sometimes be seen in skull
X-ray photographs.

Menstruation

Menstruation, periodic vaginal discharge in humans,
consisting of blood and cells shed from the endometrium, or lining of
the uterus. Menstruation accompanies a woman’s childbearing years,
usually beginning between the ages of 10 and 16, at puberty, and most
often ceasing between the ages of 45 and 50, at menopause. Menstruation
is part of the process that prepares a woman for pregnancy. Each month
the lining of the uterus thickens; if pregnancy does not occur, this
lining breaks down and is discharged through the vagina. The three to
seven days that menstruation lasts is called the menstrual period.

In most women the menstrual cycle is about 28 days,
but it can vary considerably even from one month to another. The cycle
is initiated by hormones in the blood that stimulate the ovaries (the
two female organs that produce ova, or eggs). Each month, hormones cause
an egg in one of the two ovaries to mature (to become capable of being
fertilized and develop into a fetus). The ovaries also produce hormones
of their own, primarily estrogen, which cause the endometrium to
thicken. About midway through the menstrual cycle, 14 to 15 days before
the next period, the ovary releases the mature egg in a process called
ovulation. The egg passes through the Fallopian tube to the uterus. If
the egg unites with a sperm on its way to the uterus, fertilization
occurs and pregnancy ensues.

The three to five days the egg takes to reach the
uterus after being released by the ovary is known as the woman’s fertile
period. If fertilization does occur, the fertilized egg attaches itself
to the enriched uterine lining and pregnancy continues. Menstruation
does not occur during pregnancy, and a missed period is often the first
indication of pregnancy a woman notices. If fertilization does not
occur, the lining of the uterus does not receive the hormones it needs
to continue the thickening process. Thus, the uterine lining breaks down
and is discharged from the body during menstruation.

Many women experience premenstrual discomfort.
Tenderness of the breasts and a tendency to retain fluid (bloat) are
common one to seven days before each period. Some women also experience
a condition called premenstrual syndrome (PMS), which is characterized
by headaches, irritability, nervousness, fatigue, crying spells, and
depression with no apparent cause. A few women also experience menstrual
cramps (dysmenorrhea) during the first day or two of the period.
Although premenstrual symptoms and discomfort during menstruation were
once thought to be of psychological origin, research now indicates that
hormonal and chemical changes are responsible.

Physical Changes

Beard

Beard, heavy growth of hair on the chin, cheeks, and
adjacent parts of the face of the human adult male. The beard generally
begins to grow during puberty, when the texture is soft and downy. In
maturity the beard, often the same color as the hair on top of the head,
is, as a rule, more wiry. The amount of facial hair varies among the
peoples of the world. For example, the beard is especially luxuriant
among Caucasian peoples, whereas among the Native North Americans it is
markedly thin. In ancient times among many peoples the beard was
considered a sign of strength and manhood; it was highly prized, and
removal was regarded as a degrading punishment. The early Egyptians,
however, usually shaved their beards, except in time of mourning. Among
the Jews an unkempt, neglected beard was a sign of grief. In Greece all
men wore beards until the 4th century bc, when the Macedonian conqueror
Alexander the Great ordered his soldiers to shave as a precaution
against being seized by the beard in battle.

Breast

Breast, one of a pair of glandular organs in mammals
that secrete milk for newborns and infants. Also known as a mammary
gland. In humans, the female breast has a distinctive rounded shape
while the male breast remains flat and undeveloped. Only mature females
can produce milk, which is rich in nutrients, antibodies, and other
substances that aid in a baby’s growth and development.

The surface of a human breast has a circular,
pigmented area in the center called the areola. The nipple, a rounded
protruding structure, lies in the center of the areola. In mature women
the breast contains a collection of 10 to 15 tubes, called ducts, that
connect to the nipple. These ducts branch out from the nipple into the
interior of the breast, ending in clusters of rounded cells, called
lobules, that produce the milk. In addition to the structures directly
connected with the production and outflow of milk, the breast is
composed of fatty tissue and ligaments that provide support and shape.

In humans, a woman’s breast size and shape vary
widely, depending on her age and whether she is pregnant or going
through a menstrual cycle. Breast development begins in girls about 10
to 12 years old, when the ovaries start to produce the hormone estrogen.
Completion of breast development, which occurs around 16 to 18 years
old, requires the interaction of other hormones such as progesterone,
prolactin, and corticosteroids.

After breast growth is completed, the breasts
typically undergo monthly cyclic changes in response to fluctuating
hormone levels in the blood that occur during the menstrual cycle. Just
before the onset of menstruation, the breasts are often swollen and
tender because the ductal system expands in preparation for pregnancy.
If pregnancy does not occur, the estrogen level falls and the breasts
return to normal.

During pregnancy there is a remarkable growth of
ducts and lobules in the breast along with a thickening of the nipples.
After a baby is born, the hormone prolactin stimulates milk production
in the breast. Initially, the breast produces a thick yellow liquid
called colostrum, which is particularly rich in the disease-fighting
substances called antibodies. Within three to five days, the breast
produces milk as the suckling infant stimulates the release of another
hormone called oxytocin. This hormone causes contractions in the network
of cells that surround the ducts and lobules, so that milk readily flows
from the breast and into the mouth of the hungry infant. As a woman
passes the childbearing age and enters menopause, the ovaries stop
producing estrogen. The decreased stimulation from this hormone causes
the milk-producing ducts and lobules in the breast to be replaced with
extra fatty tissue.

Breasts are naturally lumpy, but any area of the
breast that becomes more prominent than the surrounding tissue or feels
unusually firm requires the attention of a physician. Breast lumps are a
common problem in women and may range from a cyst, a fluid-filled
structure that does not pose a cancer risk, to breast cancer, the most
common type of cancer in women other than skin cancer. Also, in men
between 20 and 40 years of age, breast enlargement can be a sign of
testicular cancer, and breast lumps in men over 40, although rare, can
be an indication of breast cancer.

Often one of the first diagnostic tests performed to
evaluate a lump, an ultrasound is able to distinguish a cyst from a
solid mass, a possible indication of cancer that requires further
investigation. Solid lumps are evaluated with a special X-ray procedure
called a mammogram, currently the best tool available for early
detection of breast cancer. A mammogram may be followed by needle
aspiration, a type of biopsy in which cells are removed from the lump
and examined under a microscope. If these test results are normal, the
lump is unlikely to be cancer. It may be removed or monitored carefully
for signs of growth. If cancer is suspected, or if the lump shows signs
of growth later, surgical removal is usually necessary.

As a preventive measure, physicians encourage regular
breast self-examinations in which a woman uses her fingers to feel for
changes in breast shape and fluid discharge from the nipple. Physicians
also urge women to have regular mammograms, which can detect very small
cancers before a lump begins to develop. These small cancers typically
respond to treatment better than cancers that have grown large enough to
produce a lump. The American Cancer Society recommends that women age 40
to 49 have a mammogram every 1 to 2 years and women age 50 and older
have a mammogram every year.

Hair

In humans the development of the hair begins in the
embryo, and by the sixth month the fetus is covered by a growth of fine
hair, the lanugo. In the first few months of infancy the lanugo is shed
and is replaced by hair, relatively coarse over the cranium and the
eyebrows, but fine and downy over the rest of the body. At puberty
coarse hair develops in the armpits and over the pubic region in both
sexes; in males facial hair begins to grow coarse to form the beard. The
rate of growth of the hair varies with the age of the person and with
the length of the hair. When a hair is short, its rate of growth
averages about 2 cm (about  in) per month; by the time the hair
is a foot long, the rate of growth is reduced by one-half. The fastest
growth is found in women from 16 to 24 years of age.

Disorders of the hair shaft or hair follicle cause
abnormal growth or abnormal or premature falling of the hair. Certain
abnormal conditions such as dull or dry hair are caused by physical or
chemical agents. Too frequent use, for instance, of permanent-waving
chemicals or of shampoos or lotions, especially those containing alcohol
or free alkalies, often causes such conditions. The cause of excessive
hairiness is obscure, but in several cases it has been traced to tumor
of the adrenal cortex or to disorders of the pituitary gland, the
thyroid gland, or the ovary. Premature graying of the hair is associated
with anxiety, shock, deficiency diseases, and, in certain cases,
hereditary elements.

Alopecia, or baldness, is also due principally to
hereditary elements. Certain forms of baldness may, however, be due to
other causes: alopecia prematura, in which the hair of a young person
falls out without preliminary graying, may also be caused by seborrhea;
while alopecia areata, in which the hair falls out in irregular patches,
is believed by doctors to be caused by inflammation, nerve disorders, or
local infections. Diffuse falling of the hair, ordinarily a normal
phenomenon, may reach abnormal proportions after a fever higher than
39.4° C (103° F), during a debilitating disease, or as a result of
invasive surgical procedures. No nonprescription hair
“restorers” actually prevent hair loss or grow hair.

Infections of the hair follicle also cause a variety
of hair diseases. Tinea favosa, or favus, is caused by the fungus Achorion
schœnleinii; it is characterized by the formation around the mouths
of the follicles of small crusts, which frequently resemble a honeycomb.
Tinea trichophytina, or ringworm, is caused by fungi of the genus Trichophyton.
Hairy parts, particularly of the head and pubis, are subject to
troublesome infestations by minute insects and mites, such as chiggers
and lice.

Thymus Gland

Thymus Gland, name applied to a structure located
just beneath the upper portion of the sternum in almost all vertebrates.
The thymus gland consists chiefly of lymphatic tissue and contains a few
small areas of epithelial tissue known as Hassall’s corpuscles. The
human thymus gland increases in weight in the first two years of life,
and from then until puberty it grows slowly to a weight of about 43 g
(about 1.5 oz). After puberty, it shrinks gradually and the lymphatic
tissue of the thymus gland is replaced by fat. In the adult human the
organ is chiefly composed of fatty tissue. Scientists generally agree
that the thymus gland plays an important role in the development of
immune responsiveness in early life. It is a site of formation of
lymphocytes and a site of antibody production. Whether or not it has any
other endocrine functions is uncertain.

Larynx

In the human larynx, two pairs of vocal cords are
present. They are made of elastic connective tissue covered by folds of
mucous membrane. One pair, the false vocal cords, extends from the
epiglottis to the angle of the thyroid cartilage; these cords narrow the
glottis (the pharyngeal opening of the larynx) during swallowing. Below
the false cords are the true vocal cords, extending from the arytenoid
cartilages to the angle of the thyroid cartilage. Vibration of this pair
of cords by air passing out of the lungs causes the formation of sounds
that are amplified by the resonating nature of the voice box. The pitch
of the sound is voluntarily controlled by muscles that rotate the
arytenoid cartilages toward the center of the body (slackening and
lengthening the cords) for low tones, and toward the sides of the body
(shortening the cords and pulling them taut) for high-pitched tones. The
extent of the angle formed by the plates of the thyroid cartilage
determines the depth of the human voice. The angle decreases in males at
puberty, causing decreased tension of the vocal cords and a consequently
deeper voice, and increases in most females at puberty, causing
increased tension of the vocal cords.

The commonest affliction of the human larynx is
inflammation, or laryngitis, often accompanying colds and accompanied by
a temporary diminution or complete loss of voice. Other diseases
commonly attacking the larynx include croup, diphtheria, and cancer.
Laryngeal cancer has been shown to be caused by cigarette smoking and by
the intake of large amounts of alcohol. Persons who smoke and drink
excessively run an especially high risk of developing cancer of the
larynx. It is treated by X-ray therapy, especially if diagnosed early,
and by surgery. Surgical procedures include partial and total removal of
the larynx. In instances of total removal, the patient must learn a new
method of speech that involves, in part, swallowing air and bringing it
up again. Various other surgical techniques have been developed to
replace the removed tissue and restore speech of near normal quality;
for example, insertion of a prosthetic device through a
tracheoesophageal puncture has shown a promising rate of success in test
patients.
