Testosterone levels in men decline gradually from the mid-thirties onwards. The symptoms that follow, including fatigue, low mood, reduced libido, weight gain, and difficulty concentrating, are often attributed to stress or ageing and left untreated.
The male menopause, also known as testosterone deficiency, androgen deficiency, or late-onset hypogonadism, refers to the gradual decline in testosterone that most men experience from their mid-thirties onwards. Unlike the female menopause, the change is gradual rather than sudden, which means symptoms often creep up slowly and go unrecognised for years.
The condition affects a significant proportion of men over 40 and a growing number of younger men, and it is frequently dismissed or misattributed. You can read more in our blog post on the male menopause.

Symptoms of low testosterone can affect almost every aspect of daily life. Common ones include: persistent fatigue that is not explained by sleep or workload; low libido and reduced interest in sex; erectile dysfunction or reduced quality of erections; low mood, irritability, or a flat feeling that does not lift; difficulty concentrating; reduced muscle mass and increased body fat, particularly around the abdomen; loss of body hair; and sleep difficulties.
These symptoms overlap with many other conditions, which is why proper blood testing and a thorough consultation are essential before reaching any conclusion.

A blood test measures total testosterone, free testosterone, SHBG (sex hormone binding globulin), and other relevant markers. Because testosterone levels fluctuate through the day and are affected by sleep, stress, and illness, Dr Dan interprets results in the context of your full clinical picture rather than relying on a single number.
Normal ranges are broad, and some men feel symptoms at levels that would appear within the normal reference range. Dr Dan takes the patient’s experience seriously alongside the numbers. You can read more about SHBG and its role in testosterone availability in our blog post on SHBG and active testosterone.
Testogel (topical gel) Applied daily to the shoulders, arms, or abdomen. Easy to use, avoids injections, and has a good long-term cardiovascular safety profile. The main considerations are daily application, variability in absorption between individuals, and the small risk of transfer to another person through skin contact.
Nebido (testosterone undecanoate) A long-acting injection given every three months after an initial loading period. It requires only four injections per year, but levels fluctuate over the three-month cycle and dose adjustment is less flexible.
Sustanon A blend of four testosterone esters given every one to three weeks, or used in smaller microdoses once or twice a week. It offers more flexibility and is well suited to microdosing protocols. Both Nebido and Sustanon are licensed in the UK.
The right choice depends on your lifestyle, preference, and clinical profile. Dr Dan will discuss the options and make a recommendation based on your individual situation.

An initial consultation is £185 for registered patients or £215 for new patients. Testosterone medication costs vary depending on the type prescribed. Full pricing is on the pricing page.



Dr Dan takes a careful, evidence-based approach to male hormone therapy. The goal is not simply to bring testosterone levels into a normal range on paper, but to help each patient feel well and function at their best. That means thorough assessment, honest conversations about risks and benefits, and close monitoring throughout. Sleep, stress, diet, and exercise are also addressed alongside any medication.
Wow! Dr. Dan was extremely knowledgeable and attentive to my health and well being. I’m so glad to have found him!
I have been going to Dr Wright for a number of years now. He is highly knowledgeable, compassionate, open minded and efficient, I couldn’t recommend him highly enough
I have been a patient of Doctor Dan for some time and continue to consult with him despite having left the UK. Dan has the enthusiasm and energy of a young man, whilst taking the holistic “physician” approach of an old school family doctor, equipped with the most modern insights and technology.
Dr Jain was great. Expert knowledge with practical advice
Before treatment, Dr Dan will arrange testosterone levels (total and free), SHBG, PSA, full blood count, liver function, and other markers as appropriate. These establish a baseline and rule out any conditions that would affect suitability for treatment.
Yes. Testosterone therapy suppresses the body’s own testosterone production and reduces sperm count, which can affect fertility. If you are planning to conceive in the near future, Dr Dan will discuss alternative approaches. Fertility effects are typically reversible on stopping treatment.
NHS testosterone prescribing for hypogonadism is available but can be difficult to access and often involves lengthy waits. Private treatment at The Wright Practice allows faster assessment, more flexibility in treatment choice, and closer ongoing monitoring.
Yes. Sleep quality, resistance exercise, reducing alcohol intake, managing stress, and maintaining a healthy body weight all support healthy testosterone levels. Dr Dan discusses these alongside any medical treatment.
Nebido is a long-acting injection given every three months after an initial loading period, requiring fewer injections but with less flexibility. Sustanon is a blend of four testosterone esters given every one to three weeks and can be used for microdosing. Dr Dan will recommend the most appropriate option for your circumstances.
This depends on the underlying cause and your response to treatment. Some men continue long-term; others may find that addressing lifestyle factors allows them to reduce or stop medication over time. Dr Dan will review this with you regularly.
Yes. While testosterone deficiency is more common in men over 40, it can affect younger men too. Dr Dan assesses each patient individually and does not apply age-based cutoffs.
The frequency depends on the treatment type. Follow-up blood tests are arranged regularly throughout treatment. Dr Dan will set out a monitoring schedule at the start of your programme.
