Are your lifestyle habits questionable? They could be impacting your ability to achieve an erection.
In part one, we illustrated the hormones associated with male sexual health and some of the underlying mechanics of performance. For part two, we wanted to stress that your choices in life will impact your health in surprising ways and that positive change is within reach.
This time of year, when motivation is naturally higher for many, is a useful entry point for affecting personal changes. Building new habits, breaking old ones, and sustaining them over time is rarely simple. Starting small, choosing goals that feel realistic, and identifying what actually motivates you tends to be far more effective than drastic overhauls that don’t last.
Perhaps knowing how better habits affect your sexual prowess will help!
Physical Activity and Hormones
Regular exercise directly influences the hormonal and vascular systems that make erections possible. Point blank. Movement affects how hormones are produced, how efficiently they signal, and how well blood vessels respond during sexual arousal. Low activity equals a multi-system internal slowdown, but when regular physical activity is reintroduced, those same systems often recover in parallel.
Exercise in general helps regulate testosterone, cortisol, insulin, and growth hormone. Aerobic activity improves cardiovascular efficiency and increases nitric oxide availability, a compound essential for relaxing smooth muscle and allowing blood to flow into the penis. Resistance training supports testosterone production, preserves lean muscle mass, and improves insulin sensitivity. Pelvic floor exercises strengthen the muscles directly responsible for erectile rigidity and ejaculatory control, reinforcing the physical mechanics of performance.
Physical activity also improves many of the underlying health conditions that commonly interfere with erectile function. Regular movement lowers blood pressure, stabilizes blood sugar, reduces abdominal fat, and dampens chronic inflammation.
So, what do we mean by “being active?” First of all, it doesn’t have to be extreme; in fact, it’s better if it’s not. (Overly strenuous exercise can be just as bad for you as no exercise.) You want to elevate and sustain the heart rate at a level where breathing is faster but still controlled. Brisk walking, cycling, swimming, rowing, or light jogging done consistently for 20 to 40 minutes should do the trick.
Strength training involves compound movements that recruit large muscle groups, like squats, deadlifts, lunges, push-ups, rows, and overhead presses. Engaging in this type of exercise two to three times per week stimulates testosterone signaling, preserves muscle mass, and improves insulin sensitivity.
Stretching is often overlooked, but it matters more than most men realize. Maintaining hip, lower back, and pelvic mobility supports nerve signaling, blood flow, and pelvic floor function, while also reducing injury risk and improving recovery between workouts in the gym and the bedroom.
If you have underlying health conditions that limit activity, be realistic – modify rather than intensify. Talk to a trainer as well as your doctor about which exercises are modest enough to keep you out of trouble but also intense enough to get what you want out of it. The point is to create a positive feedback loop: improved circulation and hormone balance support sexual performance, improved energy and confidence reinforce healthier habits, and the system begins to self-correct.
Diet and Hormones
The visible result of constant overindulgence is seen in your waistline, but what you don’t see right away is the influence of diet on hormones and blood vessels. Diet provides the raw materials for hormone production, determines how well those hormones signal, and correlates directly with vascular health.
An often misunderstood piece of this is cholesterol. Surprise! It’s a foundational building block from which testosterone and other steroid hormones are made. Diets that are overly restrictive, chronically low in calories, or devoid of healthy fats can blunt hormonal signaling and suppress output. But wait, aren’t we supposed to restrict dietary cholesterol?
The body produces most of its own cholesterol in the liver, and how much it makes varies from person to person based on genetics, activity level, and metabolic health. For some men, dietary cholesterol has very little effect on blood levels; for others, it can raise them more noticeably. The goal in managing cholesterol isn’t to eliminate it altogether, but to find ways to maintain levels that support bodily processes without compromising blood vessel health. This happens by having an open dialogue with your physician about lab trends, diet, and overall risk.
A healthy cardiovascular system (and sexual performance) depends on more than cholesterol levels. Arteries that can respond quickly, relax fully, and deliver blood efficiently make for a solid erection and the stamina to use it. A healthy diet influences this responsiveness through inflammation control, blood sugar regulation, and protection of the vascular lining.
Diets built around vegetables, fruits, whole grains, lean proteins, and unsaturated fats are what you want to aim for. Foods rich in antioxidants and natural nitrates help maintain nitric oxide availability, allowing penile arteries to dilate appropriately during arousal. Leafy greens, beets, and berries help blood vessels relax and improve circulation. Whole grains and legumes regulate blood sugar and cholesterol, protecting the arteries. Healthy fats from olive oil, nuts, avocados, and fatty fish support cardiovascular function and provide the building blocks for hormone production. Lean proteins help preserve muscle mass and metabolic health.
Diets that are high in refined carbohydrates, excess sugar, and unhealthy fats do the opposite: they promote inflammation, insulin resistance, and vascular stiffness that impair blood flow everywhere, including to the penis. Target sustainable eating habits that include indulgences now and then; this tends to improve mood, reduce stress, enhance quality of life, and support sexual wellbeing. Like exercise, dietary changes don’t have to be extreme to be effective, just consistent.
Specific nutrient supplements might also be beneficial, depending on your personal health history. Zinc is critical for testosterone synthesis and for the signaling pathway that tells the testes to produce it. Magnesium helps reduce inflammation and oxidative stress while improving the availability of free testosterone. Vitamin D functions more like a hormone than a vitamin, has receptors throughout the body (including penile tissue), and deficiencies are commonly associated with both low testosterone and erectile dysfunction.
Lifestyle Optimizes Treatments
Even the most advanced therapies perform better when the body isn’t fighting against chronic inflammation, vascular disease, or hormonal traffic jams. Testosterone replacement therapy (TRT), oral or injectable ED medications, vacuum devices, and even penile prostheses are all highly effective when deployed within a system that is actively supported by healthy habits. Regular exercise, balanced nutrition, and metabolic health improvements create the environment that allows these therapies to reach their full potential – the interventions can be life-changing, but you still have to do the work to keep the system fully operational.
Multiple “drivers” (hormones, nerve signals, blood vessels, raw building blocks, and psychological cues) are moving through your body simultaneously, and sexual function is rarely a single-lane issue. Your choices – how you move, what you eat, how you sleep, and how you manage stress – influence whether those drivers arrive efficiently at their destinations. When the highway is clear and the traffic flows smoothly, your body is positioned to perform at its best, in the bedroom and beyond.
