By means of a developed method of histotopographical sections cartograms, 146 preparations obtained from female persons at the age of 8-25 years have been studied. The organ is intensively developing not only at 12-16 years of age, but at 22-25 years, as well. A close correlation is noted at 10-11 years of age between the mammary gland mass and the degree of its parenchyma (glandular tree) development. Subsequently, the connection between these indices becomes essentially weaker. At the age of 15-25 years, according to the variability and standard deviation quantile classes reflecting stages in the organ formation (the degree of the glandular tree development), five types of the mammary gland are distinguished: weak, low middle, middle, high middle and high. During transition of the mammary gland from the weak to the high type, at first the glandular tree is intensively developing in the periphery and in the internal parts, and then in the external squares and in the center of the organ. The degree of uneven development in the glandular tree increases when the middle type is reached. Subsequently, it decreases up to the initial level.
通过一种已开发的组织拓扑切片图表法，对146份取自8至25岁女性的标本进行了研究。该器官不仅在12至16岁时发育旺盛，在22至25岁时也同样如此。在10至11岁时，乳腺质量与其实质（腺树）发育程度之间存在密切相关性。随后，这些指标之间的联系变得明显减弱。在15至25岁时，根据反映器官形成阶段（腺树发育程度）的变异性和标准差分位数类别，区分出五种类型的乳腺：弱型、低中型、中型、高中型和高型。在乳腺从弱型向高型转变的过程中，起初腺树在周边和内部密集发育，然后在器官的外部区域和中心发育。当达到中型时，腺树发育的不均匀程度增加。随后，它又降至初始水平。
