In biological terms, human development entails growth from a one-celled zygote to an adult human being.
Growth from any such meristem at the tip of a root or shoot is termed primary growth and results in the lengthening of that root or shoot. Secondary growth results in widening of a root or shoot from divisions of cells in a cambium. [39] In addition to growth by cell division, a plant may grow through cell elongation. [40]

The upper part of the gubernaculum degenerates. The lower part persists as the gubernaculum testis ("scrotal ligament"). This ligament secures the testis to the most inferior portion of the scrotum, tethering it in place and limiting the degree to which the testis can move within the scrotum.
