Testicular morphometric studies in Nigerian males

A total of 102 autopsy subjects found to have seemingly normal testicular picture were analysed to determine acceptable normal morphometric values. The mean tubular diameter in the last trimester of intrauterined life is 43.8 mu in contrast to adult value of 173.0 mu. The mean basement membrane thickness increases from 3.2 mu in the last trimester to 6.9 mu in the 10-14 years age range. The adult mean testicular score count is 19.3 in contrast to 5.3 observed in the last trimester. While Sertoli cells predominate in the last trimester of intrauterine life, many spermatozoa are seen during the period 15-19 years.
