Hence, this article was aimed to identify the functional and morphological characterization of the corpus cavernosum in aged rats and to evaluate the effects of the Angiotensin II type 1 receptor antagonist losartan on age\u2010related ED (AED).<\/jats:p><\/jats:sec><jats:sec><jats:title>Material and Methods<\/jats:title><jats:p>A total of 40 young and aged Sprague Dawley rats were randomly divided into four groups (n\u00a0=\u00a010 per group): young rats as normal controls (YNC) group; aged rats with normal erectile function (ANC) group; aged rats with ED (AED) group; and a losartan\u2010treated AED (AED\u00a0+\u00a0Losartan) group. The treated group received losartan (30\u00a0mg\/kg) once daily oral gavage for 4\u00a0weeks. Erectile function was measured by the ratio of peak intracavernous pressure (ICP)\/mean arterial pressure (MAP), and relevant tissues were harvested for transmission electron microscopy, Immunohistochemistry, Masson's trichrome staining, TUNEL, caspase\u20103 activity assay and Western blot.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The AED group exhibited decreases in erectile response and increases in the role of apoptosis, fibrosis as well as oxidative stress, compared with the control groups. After daily administration of losartan for four weeks, it could slightly restore erectile function and significantly attenuate corporal apoptosis, fibrosis, and oxidative stress of AED. However, the result was still not comparable with that of the control groups. Moreover, the expression levels of p\u2010Bad\/Bad and p\u2010AKT\/AKT were significantly lower, whereas the expression levels of Bax\/Bcl\u20102, Nrf2\/Keap\u20101, Fibronectin, HO\u20101, and caspase\u20103 activity were significantly higher in the AED groups and while losartan could significantly attenuate these changes of AED, it was still not comparable with that of the control groups.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Our results indicated that administration of losartan not merely restored erectile function, but also significantly
