Two ultrastructurally distinct types of Leydig cells were observed in the equine testis. Whereas the adult testis exhibited both postpubertal and adult Leydig cells, the testis of the pubertal horse contained only the postpubertal type, and that of the aged horse contained only the adult type. However, Percoll-purified testicular preparations from pubertal, adult, and aged horses all exhibited two distinct Leydig cell populations. The quantitative distribution and the functional characteristics of these Leydig cell populations (ability to bind human chorionic gonadotropin [hCG] and increase of testosterone production after hCG stimulation) evolved with the age of the horse. It is concluded that equine Leydig cells derive from two redundant successive postnatal generations and that there is no strict correlation between the functional properties and the morphological characteristics of these cells.
