As the castrato's body grew, his lack of testosterone meant that his epiphyses (bone-joints) did not harden in the normal manner.
In the bones, estradiol accelerates ossification of cartilage into bone, leading to closure of the epiphyses and conclusion of growth.
Secondary ossification occurs after birth, and forms the epiphyses of long bones and the extremities of irregular and flat bones.
The diaphysis and both epiphyses of a long bone are separated by a growing zone of cartilage (the epiphyseal plate ).
When the child reaches skeletal maturity (18 to 25 years of age), all of the cartilage is replaced by bone, fusing the diaphysis and both epiphyses together (epiphyseal closure).
