Low Testosterone Specialist on Long Island
Comprehensive Hormone Evaluation & Testosterone Replacement Therapy on Long Island
What Is Low Testosterone?
Testosterone is the primary male sex hormone. It controls sex drive, energy, muscle mass, bone density, mood, and much more. When levels fall too low — a condition called hypogonadism — the impact on quality of life can be significant.
Testosterone levels naturally decline with age — typically about 1% per year after age 30. But for some men, levels drop much more than expected, causing real symptoms that interfere with daily life, relationships, and overall wellbeing.
Low testosterone is very common and very treatable. The key is getting a proper diagnosis — not just a single blood test, but a thorough evaluation that rules out other causes and confirms that your symptoms are truly related to low T.
Not just "getting older": Many men chalk up symptoms like fatigue, low libido, and brain fog to aging. But these symptoms are not inevitable — they may be signs of low testosterone that can be effectively treated.
Quick Answers About Low Testosterone
What are the symptoms of low testosterone?
Possible symptoms include reduced sex drive, fewer or weaker erections, low energy, depressed mood or irritability, and reduced muscle mass. These symptoms aren’t specific to low testosterone, so diagnosis requires symptoms plus repeatedly low morning testosterone blood tests.
Is testosterone replacement therapy safe long-term?
For men with properly diagnosed testosterone deficiency, TRT can be used long-term with ongoing monitoring of testosterone levels, blood counts, and prostate health. It isn’t automatic for everyone — treatment is individualized and a clinician should follow you regularly.
Will TRT affect my fertility?
Yes. TRT can suppress the brain signals that drive sperm production, sometimes severely. If current or future fertility matters, tell your doctor before starting — fertility-preserving alternatives exist, and a reproductive urologist can advise.
TRT injections vs gels — which is better?
Neither is universally better. Injections are often less expensive with no skin-transfer risk but cause peaks and troughs; gels give steadier daily levels but need daily application and precautions against transfer to others. The right choice depends on preference, insurance, lifestyle, and lab response.

Symptoms of Low Testosterone
Low T affects nearly every system in the body. Symptoms are often subtle at first and tend to be dismissed as stress or aging. If you are experiencing several of these, it is worth getting tested.
Fatigue & Low Energy
Persistent tiredness that doesn't improve with sleep. Many men describe feeling "flat" or lacking the drive and motivation they used to have.
Low Sex Drive (Low Libido)
A noticeable decrease in interest in sex. This is one of the most common and distressing symptoms of low testosterone for men and their partners.
Erectile Dysfunction
Low T can contribute to difficulty getting or maintaining erections. It is often a co-existing factor alongside vascular causes of ED.
Brain Fog & Poor Concentration
Difficulty focusing, memory lapses, and mental cloudiness are common complaints in men with low testosterone.
Depression & Irritability
Testosterone plays a key role in mood regulation. Low levels are strongly associated with depression, anxiety, and increased irritability.
Weight Gain & Muscle Loss
Low T reduces muscle mass and increases body fat — particularly around the abdomen. This can create a cycle that further lowers testosterone levels.
Bone Density Loss
Testosterone helps maintain bone density. Prolonged low T can increase the risk of osteoporosis and fractures.
Hot Flashes & Night Sweats
Often thought of as a female symptom, hot flashes and night sweats can occur in men with low testosterone — especially when levels drop rapidly.
How Is Low Testosterone Diagnosed?
Diagnosing low T properly requires more than a single blood test. Dr. Kashani performs a comprehensive evaluation to confirm the diagnosis and understand the underlying cause before recommending treatment.
Testosterone levels should be measured in the morning when levels are highest. Two separate low readings — combined with symptoms — are typically required to confirm the diagnosis. Dr. Kashani also checks Free Testosterone, LH, FSH, prolactin, and estradiol to understand why testosterone is low and whether there are other contributing issues.
Beware of "Low T clinics": Many men's health clinics treat based on a single blood test without a full workup. This can miss other important diagnoses and lead to inappropriate treatment. Dr. Kashani takes a thorough, evidence-based approach.
Testosterone Replacement Therapy (TRT) Options
There is no one-size-fits-all approach to TRT. Dr. Kashani works with each patient to choose the delivery method that best fits their lifestyle, preferences, and medical needs — and monitors treatment closely to ensure safety and effectiveness.
Testosterone Injections
Injections are the most widely used form of TRT. Testosterone cypionate or enanthate is injected subcutaneously in the abdomen or intramuscularly in the thigh/buttocks — weekly, biweekly, and sometimes as a split dose. Injections produce reliable, measurable results and are cost-effective. Most men self-inject at home after training.
Testosterone Gels & Creams
Applied to the skin daily, testosterone gels provide steady hormone levels without injections. They are convenient and easy to use. The main consideration is avoiding skin-to-skin contact with partners or children after application until the gel has dried.
Oral Testosterone (Jatenzo®)
Jatenzo is an FDA-approved oral testosterone capsule — a newer option for men who prefer not to use injections or topical gels. It is taken twice daily with food. Unlike older oral testosterone formulations, Jatenzo is designed to be absorbed through the lymphatic system, reducing the liver burden associated with older oral androgens.
Clomiphene (Clomid) & hCG
For younger men or those who wish to preserve fertility, alternatives to direct testosterone replacement may be used. Clomiphene citrate (Clomid) and hCG stimulate the body's own testosterone production rather than replacing it externally. These options maintain natural sperm production — important for men who may want children in the future.
Frequently Asked Questions
What is a "normal" testosterone level?
Normal total testosterone is generally considered between 300 and 1000 ng/dL. However, "normal" varies by lab and by age. More important than the number is how you feel — some men feel terrible at 350 ng/dL while others feel fine. Dr. Kashani evaluates your symptoms alongside your numbers to make the right call.
How quickly will I feel results from TRT?
Most men notice improvements in energy and mood within 3 to 6 weeks. Sexual function and libido typically improve within 3 to 6 months. Body composition changes — muscle gain and fat loss — take longer, usually 6 to 12 months of consistent therapy.
Do I have to stay on TRT forever?
Some men use TRT for a defined period while addressing lifestyle factors like weight loss and exercise. Others choose to stay on it long-term because the benefits are significant. Dr. Kashani will periodically reassess whether TRT is still appropriate and whether dose adjustments are needed.
Is TRT covered by insurance?
TRT is often covered by insurance when there is a confirmed diagnosis of hypogonadism with appropriate lab results and symptoms. Dr. Kashani's team can help verify your benefits. Generic testosterone cypionate injections are very affordable even without insurance.
Can low testosterone cause erectile dysfunction?
Yes — testosterone plays a role in sex drive and in maintaining the vascular and nerve pathways that support erections. Many men with low T notice a drop in libido before they notice ED. Treating low testosterone can improve sexual function, though some men also benefit from specific ED treatment alongside TRT. Dr. Kashani evaluates both together.
Can younger men have low testosterone?
Yes — while testosterone naturally declines with age, low T can affect men in their 20s and 30s as well. Common contributing factors in younger men include obesity, chronic stress, poor sleep, and certain medical conditions. If you're a younger man experiencing fatigue, low libido, or mood changes, it's worth having your levels checked.
What's the difference between seeing a urologist for low T versus a franchise "Low T clinic"?
Franchise low-T clinics typically offer a single blood test and a quick prescription — often without fully exploring why testosterone is low or whether other conditions are involved. Dr. Kashani performs a thorough hormonal and medical evaluation, considers the full picture, monitors your therapy with regular follow-up, and has the expertise to address related concerns like fertility, prostate health, and erectile function.
What happens if I stop TRT?
Your body's natural testosterone production will gradually resume, though it can take weeks to months to normalize. Most men notice a return of some symptoms during this time. If you're considering stopping — to try for a child, take a break, or explore alternatives — Dr. Kashani can guide a planned transition to make the process smoother.
