It is generally considered to start with puberty, during which sexual maturation occurs and adolescents go through a spurt in growth. In many children, however, puberty actually begins during the stage called pre-adolescence, which covers the ages 11 to 12 years. Puberty may begin before adolescence, but it usually continues for several years, well into the adolescent stage, which ends during the late teens. Besides the physical changes of puberty, adolescence is also a time of significant cognitive and psychosocial changes. Many of these changes continue through the end of adolescence after most of the physical changes of puberty have already taken place. Puberty Puberty is the period during which humans become sexually mature. Besides maturation of the primary sex organs (those involved directly in reproduction), secondary sex characteristics also emerge during puberty. Adolescents with a high level of testosterone in their blood develop masculine traits (such as facial hair), and adolescents with a high amount of estrogen in their blood develop feminine traits (such as breasts). In addition, there is a period of rapid body growth during puberty, which results in sexual dimorphism in adult body size, composition, and shape. When does puberty occur? The timing of puberty depends in part on biological sex, w...

Puberty typically begins between the ages of 9 and 11, which is when physical changes start to appear. The Tanner Stages are used to describe specific changes that children and teens may experience during puberty. Puberty is a time of big changes for a teen that eventually ends with the full maturation of the body. The different stages can be challenging and even confusing for teens, especially since the timeline of these changes is different for each person. Puberty may also be difficult for any teens questioning their Explaining the process to your child can help them know what to expect. And if you or your child have any concerns about how the process is unfolding, it may even be helpful to contact your pediatrician for additional guidance. In this article, we take a look at the different stages of puberty, referred to as the “Tanner stages.” We’ll review how the body changes and what signs and symptoms to expect during each stage. Professor James M. Tanner, a child development expert, was the first to identify the visible stages of puberty. Today, these stages are known as the Tanner stages or, more appropriately, sexual maturity ratings (SMRs). They serve as a general guide to physical development, although each person has a different puberty timetable. Here’s what you can expect to see based on the Tanner stages in males and females during puberty. Tanner stage 1 Tanner stage 1 describes what’s happening to your child before any physical signs of puberty appear. It t...

What is normal breast development? Breast development is a vital part of a woman’s reproduction. Breast development happens in certain stages during a woman's life: first before birth, again at puberty, and later during the childbearing years. Changes also happen to the breasts duringthe menstrual cycleand when a woman reaches menopause. When does breast development begin? Breasts begin to form while the unborn baby is still growing in the mother’s uterus. This starts with a thickening in the chest area called the mammary ridge or milk line. By the time a baby girl is born, nipples and the beginnings of the milk-duct system have formed. Breast changes continue to happen over a woman’s life. The first thing to develop are lobes, or small subdivisions of breast tissue. Mammary glands develop next and consist of 15 to 24 lobes. Mammary glands are influenced by hormones activated in puberty. Shrinkage (involution) of the milk ducts is the final major change that happens in the breast tissue.The mammary glands slowly start to shrink. This often starts around age35. What breast changes happen at puberty? As a girl approaches her teen years, the first visible signs of breast development begin. When the ovaries start to produce and release (secrete) estrogen, fat in the connective tissue starts to collect. This causes the breasts to enlarge. The duct system also starts to grow. Often these breast changes happen at the same that pubic hair and armpit hair appear. Once ovulation and...

One’s anatomy and The reproductive organs first develop in the same form for both males and females: internally there are two undifferentiated gonads and two pairs of parallel ducts ( genital protrusion with a groove (urethral groove) below it, the groove being flanked by two folds (urethral folds). On either side of the genital protrusion and groove are two ridgelike swellings (labioscrotal swellings). Around the fourth week of life the gonads At motivation: Sexual motivation Adolescence, from a physical viewpoint, is that period between Following adolescence there are about three decades of adult life during which physiological changes are slow and gradual. While muscular strength increases for a time, the changes may best be described as slow deterioration. This physical decline is not immediately evident in sexual activity, which often increases in quantity and quality as the individual develops more social skills and higher socio-economic status and loses some of the If one must arbitrarily select an age to mark the beginning of In general, the female withstands the onslaughts of age better than the male. The reduction in the frequency of marital intercourse or even its abandonment is more often than not the result of male deterioration.

Women's life stages are based on the reproductive cycle, beginning with menstruation and continuing through menopause. To understand these stages, start with the biology. When menstruation begins during puberty, an egg is released from the ovary during ovulation each month. It travels down the fallopian tube, where it might be fertilized by a sperm. If fertilized, it implants in the lining of the uterus, and pregnancy begins. If not, the egg and lining are shed during menstruation. This continues until perimenopause — the time when your body begins the transition to menopause. Specific symptoms often mark different life stages in women. Those symptoms may include menstrual cramps, menstrual bleeding, mood swings, hot flashes, night sweats, weight gain and sexual changes, among others. Learn how healthy lifestyle choices can help you feel your best at any stage. Understand your birth control options, hormonal therapy options and what measures can be taken to improve your quality of life. When in doubt, talk to your health care provider. Cancer screenings also are an important part of your health, no matter what stage of life you're in. Make sure you know the frequency and timing of screening for cervical cancer, colon cancer and breast cancer. Talk to your health care provider about those screenings and which tests are right for you depending on your age and family history. • Women and heart disease.
