Mean (± SEM) anogenital distance (AGD) and external phallus length in naked, Damaraland, and silvery mole-rats.

1All phallus length measures were performed on live specimens except in silvery mole-rats, where measures were post-fixation. Thus, shrinkage due to fixation may have reduced these measures in silvery mole-rats, but presumably did so to a similar extent in males and females.

1. 所有阴茎长度测量均在活体标本上完成，仅银鼹形鼠（silvery mole-rats）的测量采用固定后标本。据此，固定作用引发的标本收缩可能使银鼹形鼠的测量值偏小，但推测该收缩对雌雄个体的影响程度相近。
