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 .
For pubescent girls in thelarche (the breast-development stage), the female sex hormones (principally estrogens) in conjunction with growth hormone promote the sprouting, growth, and development of the breasts. During this time, the mammary glands grow in size and volume and begin resting on the chest. These development stages of secondary sex ...
Hoffmeester recorded 15 second videos every week of his daughter, Lotte, from a newborn to a teenager and compiled them together to make a time-lapse video. He calls it "the ultimate coming of age time-lapse". He has done several videos of her being recorded to different ages, such as 12, 14, 16, 18 and 20 years old. [8] [9]

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]
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 .
Breast–chest difference, also known as bust–band difference, is a measurement used for quantifying breast size. It is calculated as bust circumference minus the band or underbust circumference. Breast–chest difference has been used in the measurement of breast development in transgender women on feminizing hormone therapy. [25] [10] [26 ...
Breast development is commonly asymmetric and one or both breasts may be small. This condition may be a congenital defect associated with underlying abnormalities of the pectoral muscle (as in Poland's syndrome [ 2 ] ), related to trauma (typically surgery or radiotherapy ) or it may be a more subjective aesthetic description.
