Penis shrinkage is one of the side effects experienced by men who had undergone treatments cancer of the prostate.

Although this side effects may not be as a common as other known types, it has been discovered that one of the reasons this side effect has never being popular is because many men don’t like discussing that bit of their health.

In others words, many men will prefer not to mention anything about their shortened penis.

A recent report published in the January 2013 issue of the journal Urology reveals details on the study conducted by researchers of the Dana-Farber Institute in Boston.

The study reveals that about 3% of men who had undergone radical prostatectomy or a combination of hormone therapy and radiation therapy complains of penis length reduction after the treatment. More details are provided below:

A diagnosis of prostate cancer is devastating for any man, but new research suggests the problems may go on long after treatment.

Boston doctors say some men have complained their manhood is smaller after treatment, affecting their sex lives and causing them to regret the type of treatment they chose.

The research, published in the January issue of the journal Urology, found complaints were more common in men treated with radical prostatectomy (surgical removal of the prostate) or male hormone-blocking drugs combined with radiation therapy.

But the researchers from Dana-Farber/Brigham and Women’s Cancer Center in Boston found no men reported a perceived shortening of their penis following radiation therapy alone.

It’s thought that some types of treatment, such as prostatectomy, can damage the nerves and tissues that cause an erection, so the penis is shortened.

The study’s findings are based on surveys completed by doctors of 948 men treated for prostate cancer and who had suffered a recurrence of the disease.

Of the 948 men in the study, 22 per cent were younger than 60 and the majority were in their 60s, 70s and 80s.

Just over half – 54 per cent – had undergone surgery to remove their cancerous prostate, while 24 per cent received radiation therapy combined with hormone-blocking treatment, and 22 per cent had radiation therapy alone.

Twenty-five men (2.63 per cent of the group) complained of smaller penises after treatment – 3.73 per cent for surgery, 2.67 per cent for radiotherapy plus androgen deprivation therapy (ADT), and none for radiotherapy alone.

Radiotherapy included both radiation administered by an external X-ray machine, and brachytherapy – the implantation of radioactive seeds directly into the prostate.

The surveys of the men did not report on their sexual functioning, but it is well-known that prostate cancer treatment can raise the risk of erectile dysfunction.

The scientific team, led by Dr Paul Nguyen, a radiation oncologist, and medical student Arti Parekh, said it is the first study to link men’s perceptions of a reduction in penis size to lowered life satisfaction, problems in emotional relationships, and misgivings about the specific form of prostate cancer treatment they chose.

Dr Nguyen said that the potential side-effect of a smaller penis is well-known among the medical community. ‘But it’s almost never discussed with patients, so it can be very upsetting to some men when it occurs,’ he said.

‘Patients can deal with almost any side effect if they have some inkling ahead of time that they may happen.’

The report’s authors said doctors should discuss the possibility with their patients so that they can make more-informed treatment choices.

There were no direct measurements of penis size either before or after treatment, said the researchers. Nor did the patients’ physicians specifically ask about this side effect; the issue was brought up by patients in conversations with their doctors.

For this and other reasons, the authors of the new study suggest that the problem is likely more common than reported in the survey.

‘Prostate cancer is one of the few cancers where patients have a choice of therapies, and because of the range of possible side effects, it can be a tough choice,’ added Dr Nguyen.

‘This study says that when penile shortening does occur, it really does affect patients and their quality of life. It’s something we should be discussing up front so that it will help reduce treatment regrets.’

The likelihood and magnitude of penis shortening as a consequence of treatment have not been well studied, said the researchers.

However, Jim Hu, a surgeon at the University of California, Los Angeles Medical Center and a co-author of the study, said previous studies had concluded there is shortened penis length following prostatectomy. Click here to read more.

Conclusively, penis shrinkage could cause regret to men who are sexual active.

Sexual Dysfunction and urinary incontinence are major side effects of associated with prostate cancer treatments, by getting to know about penis shortage or shrinkage, men now have additional area of concern.

It is important that the man should discuss with the doctor very well so as to make better treatment choices to improve the quality of life.
