Men with Penile Implants Seem Satisfied With Treatment

Men who receive penile implants for erectile dysfunction (ED) appear to be more satisfied with their treatment compared to those who try other therapies, according to a new study published in Andrology.

Men with ED – the inability to get and keep an erection firm enough for intercourse – have a variety of treatment options available to them. This study, conducted by researchers in Turkey, compared the effectiveness of and satisfaction with three types:

·         Oral medication. Drugs called phosphodiesterase type 5 (PDE5) inhibitors are usually the first treatment urologists try with their ED patients. These medications relax smooth muscle tissue in the penis and allow more blood to flow in when a man is sexually stimulated. In this study, the drug tadalafil was used.

·         Self-injection.Sometimes, oral medications either don’t work or aren’t feasible. (For example, men who take nitrates for heart disease should not take PDE5 inhibitors.) In those cases, patients might try self-injection therapy. Men inject medication into the base of their penis shortly before they’d like to have sex. The drug then triggers an erection.

·         Penile implants (prostheses).  If the above methods don’t work out, men may decide to have a penile prosthesis implanted. The penis contains two areas of spongy tissue called the corpora cavernosa, which fill with blood and give the penis the firmness it needs for an erection. In an inflatable implant procedure, these two areas are replaced with two cylinders that can fill with a reserve of saline solution when a man presses on a special pump. (Less often, malleable rods are implanted, allowing the man to raise and lower his penis by hand as needed.)

The researchers collected data from 356 men with an average age of 52 years. All of the men had ED.

The participants were divided into four groups and followed these treatment protocols for the next twelve weeks:

·         132 men (37%) took 20 mg of tadalafil twice a week.

·         106 men (30%) took 5 mg of tadalafil once a day.

·         96 men (27%) underwent injection therapy.

·         22 men (6%) underwent implant surgery (inflatable prostheses).

The men completed questionnaires that assessed their erectile function and treatment satisfaction. The satisfaction of the men’s partners was also evaluated.

Overall, the men who had penile implants had more improvement in erectile function than the men who took tadalafil (both groups) and those who used injection therapy.

In addition, the men in the implant group – and their partners – appeared to be more satisfied with their treatment than those in the other groups.

The authors reported that in general, satisfaction rates for penile implants are above 90% for both men and their partners.

However, they added that more research is needed to confirm the results of this study.
