Breast development, also known as mammogenesis, is a complex biological process in primates that takes place throughout a female's life. It occurs across several phases, including prenatal development, puberty, and pregnancy. At menopause, breast development ceases and the breasts atrophy.
Gynecomastia can be normal in newborn male babies due to exposure to estrogen from the mother, in adolescent boys going through puberty, in older men over the age of 50, and in obese men. [4] Most occurrences of gynecomastia do not require diagnostic tests.
Thelarche, also known as breast budding, is the onset of secondary breast development, often representing the beginning of pubertal development. [1] It is the stage at which male and female breasts differentiate due to variance in hormone levels; however, some males have a condition in which they develop breasts, termed gynecomastia .
A mammary gland is an exocrine gland in humans and other mammals that produces milk to feed young offspring.Mammals get their name from the Latin word mamma, "breast".The mammary glands are arranged in organs such as the breasts in primates (for example, humans and chimpanzees), the udder in ruminants (for example, cows, goats, sheep, and deer), and the dugs of other animals (for example, dogs ...
Breast development in puberty is measured with the five-stage Tanner scale The morphological structure of the human breast is identical in males and females until puberty . For pubescent girls in thelarche (the breast-development stage), the female sex hormones (principally estrogens) in conjunction with growth hormone promote the sprouting ...
The mammary ridge is primordial for the mammary glands on the chest in humans, and is associated with mammary gland and breast development.. In human embryogenesis, the mammary ridge usually appears as a narrow, microscopic ectodermal thickening during the first seven weeks of pregnancy and grows caudally as a narrow, linear ridge. [1]
The Tanner scale (also known as the Tanner stages or sexual maturity rating (SMR)) is a scale of physical development as pre-pubescent children transition into adolescence, and then adulthood. The scale defines physical measurements of development based on external primary and secondary sex characteristics , such as the size of the breasts ...
Normal histology of the breast during lactation. Mammoplasia is the normal or spontaneous enlargement of human breasts. [1] Mammoplasia occurs normally during puberty and pregnancy in women, as well as during certain periods of the menstrual cycle. [2] [3] [4] When it occurs in males, it is called gynecomastia and is considered to be ...
