decreased mammary duct terminal end bud number +   
increased mammary duct terminal end bud number 
greater number of unique club-shaped epithelial structures formed at the tip of the mammary duct at the onset of puberty (approximately 3 weeks of age in mouse) under the action of circulating hormones; normally, TEBs proliferate, ramify, and actively invade the fad pad to allow the formation of a complex branching structure; this process of branching morphogenesis concludes at about 10-12 weeks of age in mouse, when TEBs have traversed the length of the fat pad and a fully developed ductal tree has formed; increase in TEBs is often associated with increased ductal outgrowth and branching morphogenesis
