A recent study suggests an epidemiological association between chronic periodontitis (periodontal inflammation) and erectile dysfunction, similarly to the association between periodontitis and coronary heart diseases, and cerebrovascular diseases.[17] In all the three conditions (erectile dysfunction, coronary heart disease and cerebrovascular diseases), despite the epidemiological association with periodontitis, no causative connection has proved yet. Nerve or spinal cord damage: Damage to the spinal cord and nerves in the pelvis can cause erectile dysfunction. Nerve damage can be due to disease, trauma, or surgical procedures. Examples include injury to the spinal cord from automobile accidents, injury to the pelvic nerves from prostate surgery for prostate cancer (prostatectomy), radiation to the prostate, surgery for benign prostatic enlargement, multiple sclerosis (a neurological disease with the potential to cause widespread damage to nerves), and long-term diabetes mellitus. buy cialis no prescription australian online viagra viagra online buy cialis no prescription Blood glucose levels: Abnormally high blood glucose levels may be a sign of diabetes mellitus. A penile erection is the hydraulic effect of blood entering and being retained in sponge-like bodies within the penis. The process is often initiated as a result of sexual arousal, when signals are transmitted from the brain to nerves in the penis. Erectile dysfunction is indicated when an erection is difficult to produce. There are various circulatory causes, including alteration of the voltage-gated potassium channel, as in arsenic poisoning from drinking water.[2] The most important organic causes are cardiovascular disease and diabetes, neurological problems (for example, trauma from prostatectomy surgery), hormonal insufficiencies (hypogonadism) and drug side effects. Other factors leading to erectile dysfunction are diabetes mellitus (causing neuropathy). Drugs (anti-depressants (SSRIs) and nicotine are most common) What Are Ejaculation Disorders? There are different types of ejaculation disorders in men, including: Premature ejaculation: This refers to ejaculation that occurs before or soon after penetration, Inhibited or retarded ejaculation: This is when ejaculation is slow to occur, Retrograde ejaculation: This occurs when, at orgasm, the ejaculate is forced back into the bladder rather than through the urethra and out the end of the penis.
