The normal development of the ovary in childhood.
The development of the ovary during childhood has been evaluated in 52 organs obtained from autopsy of children who died in accidents or after a brief acute disease. The ovaries at all ages showed follicle growth. 93% of the organs were actively growing ovaries containing healthy and degenerating follicles in progressive stages of development with and without follicle fluid. Three ovaries showed follicle growth up to pre-antral stages. None of the 52 ovaries were quiescent in which follicle development was not in progress. It is therefore argued that the normal ovary in childhood shows follicle growth at all ages. The number and size of antral follicles increases after the age of 6 years coinciding with the progressive increase in FSH and oestrogen output in childhood.
