Erectile Dysfunction
Trouble getting or keeping an erection reaches far beyond the bedroom. Confidence drops, relationships feel strained, and many men start to worry about their overall health. A lot of men stay quiet for years, which adds stress on top of the problem.
At Riverstone Urology Specialists in Cypress, Dr. Russell Libby evaluates and treats erectile dysfunction for men from North Houston, Cypress, The Woodlands and nearby communities. He focuses on three things. Find the cause, protect long term health, and build a treatment plan that fits your goals and daily life.
What Is Erectile Dysfunction
Erectile dysfunction, often shortened to ED, means a consistent or frequent inability to achieve or maintain an erection firm enough for satisfactory sexual activity.
Important Points:
- ED is common, especially with age
- ED often has more than one cause
- ED is very treatable in most men with proper evaluation and a stepwise plan
ED is not “all in your head.” Emotional factors play a role, yet blood flow, hormones, nerves, medications, and lifestyle all matter.
How ED Feels In Everyday Life
Men Describe Ed In Many Ways, For Example:
- Erections that fade before or during intercourse
- Erection quality that changes from day to day without clear pattern
- Needing more stimulation or more time to reach firmness
- A full erection during masturbation but not with a partner, or the reverse
- Avoiding intimacy because of fear of “failing”
Studies show links between ED and lower quality of life, more relationship tension, and higher rates of depression and anxiety.
Dr. Libby treats ED as a health condition, not a character issue. That tone guides the entire visit.
Common Causes Of Erectile Dysfunction
Ed Usually Reflects A Mix Of Physical And Psychological Factors. The Main Categories Include:
Vascular (Blood Flow) Problems
- Atherosclerosis and general artery disease
- High blood pressure
- High cholesterol
- Diabetes and insulin resistance
- Smoking history
Nerve Related Causes
- Diabetes
- Pelvic or spinal surgery
- Prostate surgery or radiation
- Neurologic disorders
Hormonal Factors
- Low testosterone
- Thyroid problems
- High prolactin from pituitary disorders
Psychological And Relationship Factors
- Performance anxiety
- Depression or high stress
- Relationship conflict
Nerve Related Causes
- Diabetes
- Pelvic or spinal surgery
- Prostate surgery or radiation
- Neurologic disorders
Obesity, sleep apnea, lack of exercise, and heavy alcohol use increase ED risk and make other causes worse.
Why Ed Matters For Overall Health
ED often serves as an early warning sign for cardiovascular disease. The penile arteries are smaller than the coronary arteries, so plaque there often shows up earlier.
For many men, a first ED visit becomes the moment when hidden problems such as diabetes, high cholesterol, or sleep apnea come to light. Treating those issues helps erections and lowers heart and stroke risk at the same time.
When To See Dr. Libby
A Visit Makes Sense If You Notice:
- Ongoing trouble getting or keeping erections
- A clear change from your prior baseline
- ED plus lower desire, fatigue, or mood change
- ED after pelvic surgery or treatment for prostate cancer
- ED alongside chest pain, shortness of breath, or trouble with exercise effort
Chest pain, sudden shortness of breath, or strong pressure in the chest or jaw deserves emergency care before any ED discussion.
How Dr. Libby Evaluates Erectile Dysfunction
Ed Care At Riverstone Urology Starts With A Structured Workup, Not A Quick Refill On Pills.
History
- Onset, duration, and pattern of erectile trouble
- Night and morning erections
- Desire, mood, and energy level
- Relationship context and stress
- Medical conditions such as diabetes, heart disease, or sleep apnea
- Full medication and supplement list
- Past pelvic or prostate surgery or radiation
Physical Exam
- Blood pressure, weight, and waist size
- Heart and vascular exam
- Focused genital exam for plaques, testicular size, and hormone clues
Laboratory Tests
- Morning fasting testosterone
- Fasting glucose or A1c
- Lipids
- Other hormone tests when indicated
In more complex cases, Dr. Libby may order:
- Penile Doppler ultrasound after medication to assess blood flow and venous leak
- Additional cardiac or sleep evaluations in coordination with your other doctors
This approach sorts vascular, hormonal, nerve, medication, and psychological factors so treatment does not rely on guesswork.
Lifestyle And Risk Factor Changes
Guidelines place lifestyle changes high on the list for ED treatment because they improve erections and long term health at the same time.
Key Areas:
Exercise
Regular aerobic activity and strength training support better blood flow, weight control, and hormone balance.
Weight Management
Reducing waist size often improves erectile function, especially in men with abdominal obesity.
Sleep
Treating sleep apnea and improving sleep habits often improves testosterone and erection quality.
Smoking And Alcohol
Stopping smoking and reducing heavy drinking support vascular health and erectile function.
Stress And Mental Health
Counseling, stress management, or couples therapy often helps when performance anxiety or relationship tension plays a role.
Dr. Libby frames these steps as part of a long term plan, not as blame. Small changes often bring meaningful improvement.
First Line Medical Treatment
For Many Men, Oral Pde5 Inhibitor Medicines Provide Strong First Line Treatment. These Include Sildenafil, Tadalafil, Vardenafil, And Similar Agents.
Highlights:
- Improve blood flow into the penis during sexual stimulation
- Taken as needed before sex, or daily in some cases
- Often work best with several trials under the right conditions
Dr. Libby Reviews:
- Proper timing with meals and sexual activity
- Dose adjustment
- Interactions with nitrates and heart medicines
- Possible side effects such as flushing, headache, nasal congestion, and visual change
Men who use nitrates for chest pain or certain pulmonary hypertension drugs must avoid PDE5 inhibitors because of dangerous blood pressure drops.
Hormone treatment such as TRT or Biote hormone pellets enters the picture when low testosterone is clear on repeated testing and matches symptoms. Those therapies have their own pages and monitoring plans.
Second Line And Advanced Ed Treatments
When Pills Do Not Give Enough Help Or Side Effects Cause Trouble, Several Other Options Exist. Guidelines Describe These As Next Steps After Pde5 Inhibitors.
Vacuum Erection Devices
- A cylinder and pump draw blood into the penis
- A soft band at the base helps hold the erection
- Noninvasive and useful for some men, especially after surgery
Injection Therapy, Including Trimix
- A tiny needle places medicine directly into the side of the penis
- Medicine increases blood flow locally
- Often effective when pills give only partial response
- Requires teaching on dose, injection technique, and safety
Riverstone Urology offers Trimix injections in a structured way, with in office teaching and careful dose titration.
Intraurethral Therapy
- Medicine placed in the urethra opening
- Helpful for some men who prefer to avoid injections into the shaft
In more complex cases, Dr. Libby may order:
- Penile Doppler ultrasound after medication to assess blood flow and venous leak
- Additional cardiac or sleep evaluations in coordination with your other doctors
Wave Therapy For ED
- Low intensity focused shockwave therapy aims to improve penile blood flow and promote new vessel growth
- Best data apply to men with mild to moderate vasculogenic ED
- Riverstone Urology already offers focused wave therapy in selected men and explains evidence, expectations, and limits in detail during consults
Penile Implants (Inflatable Penile Prosthesis)
- Surgical placement of cylinders inside the penis with a small pump in the scrotum
- Provides a reliable erection on demand when inflated
- Reserved for men who want a permanent mechanical solution after other options do not meet their needs
Professional guidelines describe penile prosthesis as a safe, effective choice with high satisfaction in properly selected men.
Dr. Libby explains the full menu of options, then lines them up in a way that matches your priorities, such as spontaneity, invasiveness, and cost.
Ed, Relationships, And Emotional Health
Erections Sit At The Intersection Of Body And Mind. Many Men With Ed Report:
- Worry before every sexual encounter
- Avoidance of intimacy to prevent embarrassment
- Strain with partners who feel confused or rejected
Dr. Libby encourages open conversation with partners when possible and often suggests sex therapy or counseling alongside medical treatment, especially when anxiety or communication problems play a role. National and specialty associations highlight combined medical and psychological care as best practice for many couples.
