This descriptive cross-sectional study was carried out at Amir Al-Momenin Hospital of Zabol between March 2019 and April 2020. The couples who were candidates for intracytoplasmic sperm injection according to male factors were recruited for the study.

Lastly, we performed various molecular studies and histopathological analyses of penile tissues collected from these rats after the experiments. We found that erectile function was impaired in cold-stressed rats, with increased penile tissue fibrosis and elevated levels of TNF-<i>α</i> and necroptosis. Contrastingly, intervention with Nec-1 and Ent restored erectile function, reduced penile tissue fibrosis, and decreased TNF-<i>α</i> and necroptosis levels, consistent with the results of intervention with Sil. Based on these results, we confirmed that the TNF-<i>α</i>-mediated RIP1/RIP3 necroptosis pathway was significantly altered in cold-stressed rats.

The cross-sectional study included 100 male patients who were admitted to the coronary angiography (CAG) unit. Patients were asked if they had ED, and if present, it was graded using the International Index of Erectile Function 5. Right and left cavernosal arteries were examined using color Doppler and erection hardness to assess the peak systolic velocity (PSV) and end-diastolic velocity. Among the 52 cases that suffered from ED, most of the cases had mild grades (38.5%). All cases without ED (100%) had penile artery Doppler PSV findings ≥30 (cm/s) with an average Doppler PSV of 48.02 ± 7.49 cm/s for the right cavernosal arteries and 47.4 ± 7.17 cm/s for the left cavernosal arteries.
