title: Electron microscopic study on the elastic and elastic related fibres in the human fascia transversalis at different ages.
abstract: An electron microscopic study of the elastic fibre and elastic related fibres of the fascia transversalis of the human inguinal triangle was performed in 20 male patients aged 13 to 81 a with right indirect inguinal hernia submitted to surgical repair. The 3 fibre types comprising the elastic system (oxytalan, elaunin, and elastic fibres) tend to be ordered in a precise manner and sequence among the fibrils, fibres, and collagen fibre bundles, respectively. The present findings show that with aging, there is a decrease in the oxytalan fibres and an increase in the amorphous substance of the elastic fibres. The authors concluded that the decrease in oxytalan fibres as a function of age may be responsible for alteration in the resistance of the transversalis fascia.
