Erectile Dysfunction Case Studies

Case studies on erectile difficulties helps us understand the prevlenace, causes, types and treatment efficacies. We will divide this commentry into two types of cases studies – 1. Individual Case Study 2. Broad clinical case study

Individual Case Study 1

Daniel Strauss is a 52 year old man who reports considerable loss of erectile function and states that his condition has progressed quite a bit in the last 18 months. It has caused extreme distress to him and has adversely affected his marital life.

Daniel was being treated for high blood pressure and hypertension for the past 3 years, he was also obese at 112kgs (5ft 11in tall) and was used to a sedentary lifestyle with little or no exercise.

He stated that he has no morning or nocturnal erections but could ejaculate normally without hematospermia or pain. Physical examination revealed a normal genatalia but also showed a rotund non-tender abdomen.

Laboratory studies showed serum cholesterol 276 mg/dL, low-density lipoprotein 132mg/dL, triglycerides 286mg/dL, high-density lipoprotein 38mg/dL and post lunch blood sugar 185mg/dL. One prime suspect for his ED was the usage of hypertension controlling medications; he was on beta blocker and thiazide diuretic.

His medications were altered to a alpha 2 receptor blocker/calcium channel blocker. He was also put on a course of PDE5 inhibitor (Viagra/sildenafil). The patient responded much better erectile function within a week.

Individual Case Study 2

John Prior is a 67 year old man suffering from considerable LUTS or lower urinary tract symptoms. He reported acute ED. His sever LUTS was being considered as a possible cause. He was on a course of valsartan for controlling hypertension which successfully maintained a tab on his blood pressure.

Since the patient was suffering from both LUTS and ED, this was a delicate case as the GP had to ensure that the medications for both didn’t interact adversely. He was prescribed a low PDE5 inhibitor dose (Viagra/sildenafil 25mg) along with tamsulosin to control his LUTS.

He was also advised not to have both Viagra/sildenafil and tamsulosin within 3 hours of each other. His ED condition showed a marked improvement and he reported satisfactory erectile function.

Individual Case Study 3

Andrew Wilkins, a 24 year old young man meets with an accident. The accident fractured his pelvis and ruptured his urethra. He was hospitalised for 6 weeks and underwent multiple operations. He was sexually active and adept before the accident, but post accident he could never achieve erection and suffered from complete erectile dysfunction. He reached a point where he wanted to end his engagement.

When he finally consulted an andrologist it was found that a main artery in the penis was blocked thus inhibiting any penile erection process. Doctors performed a microsurgical bypass operation via a revascularisation procedure and removed the block. Andrew now has overcome his ED problem.

Broad Case Study – Massachusetts Male Aging Study

The Massachusetts Male Aging Study(MMAS) is one of the most acclaimed and respected studies on erectile problems. The first phase of the study started in 1987 with a followup during the period 1995-97.

The study was an obervational random sample study on men aged 40-70 that was not limited to just measure erectile dysfunction, but designed to get statistics on how a variety of health factors correleated with aging.

In its first stage, part of the test involved measuring erectile issues with regards to general prevelance but later on it attempted to measure the rate of ED in healthy men without the two common markers – “diabetes and heart diseases”, thereby trying to isolate a more accurate data of aging on men’s erectile potency.

Baseline Study (Stage 1)

The initial raw test pool comprised of 3,258 volunteers aged 40-70, but apparently the early morning tests(blood sample collection) was a deterrent for a lot of people which meant that only 1709 completed the baseline study.

All the subjects had their blood samples taken and answered a set of questions that underlined their erection quality. The study looked at clinical history, blood picture, hormonal effects, psychological traits apart from aging.

baseline ed case study results

The results showed that one out of two men over the age of 40 suffered atleast a mild form of erection problem. This re-affirmed what we already knew. Erectile dysfunction is infact pretty common. Out of the 52% of men who were assessed to have mild to complete impotence – 17% were deduced to have mild, 35% were ascertained to have moderate and 10% had severe or complete impotence.

The age-related distribution is rather predictable. The number of erectile dysfunction cases increased with age. The prevalence of men with moderate ED increased from 17% to 34% progressively between the age 40-70. Complete impotence prevalence tripled from 5% to 15% along the age scale(40-70).

The prevalence of erection troubles were decidedly tilted towards men with chronic hypertension, diabetes and heart diseases. Hypertension doubled the chances of erectile dysfunction, Diabetes tripled it and heart diseases quadrupled ED probability. Whats more, in people who were suffering from the above diseases, smoking caused the overall risk factor to be doubled.

Our inference: Imagine someone has uncontrolled diabetes and heart disease and is also a smoker – the chances of ED is increased over 20 times, ouch…

Follow-up Study (Stage 2)

A follow-up study was conducted within the same test-group to study the incidence rate amongst men without the two main prevalence markers – diabetes and heart diseases. As such, men who reported normal erectile function and without history of diabetes and heart diseases were filtered from the original study. This formed a test pool of 778 participants.

The results once again reiterated how prevalent erection issues are. It was found from the studies conducted during a 3 year period that the incidence rate was as high as 26 cases per 1000 men per year between the age group of 40-70. This is not a low number when you consider that this is amongst relatively healthy men without the 2 prime causes of sexual dysfunction and who had initially reported normal erectile function.



Case study facts

The case studies presented on this page are taken from real documented medical journals. They are accurate but the results may vary from person to person.

Causes are many and so are the treatments, but it has been found that oral treatments do work on almost every type of erectile dysfunction.

In the various case studies, it has also been found that some men who did not respond well initially to Viagra or Cialis started responding to the oral treatment after a few doses.

Prices of treatment compared

It is part of good medical practice to inform patients of the price of treatment in advance. Researchers have compiled price comparison data for oral medications from UK regulated services above. You may look at them by clicking the button below.
