Hello and welcome! I’m Fernando, a GP in the UK. In today’s episode, we’ll I go through the recommendations by the European Association of Urology (or EAU) on male hypogonadism, focusing on what is relevant in Primary Care only. The link to the guideline is in the episode description.

In today’s episode, we’ll focus on late-onset hypogonadism, its presentation, interpretation of test results, and a brief overview of the general management.

If you haven’t already, I recommend that you check the previous episode where we cover the definition, classification, causes, and clinical associations of male hypogonadism.

Right, let’s jump into it.

The diagnosis of functional hypogonadism is based on the exclusion of an organic or structural cause. The main causes suggested for functional hypogonadism are obesity, comorbidities and ageing, with the first two accounting for most cases. This is because the evidence shows that chronic comorbidities can interfere with the HP testicular axis leading to functional hypogonadism. In fact, the role of ageing in hypogonadism up to age 80 years seems relatively small.

Late onset hypogonadism is a term that is used, frequently incorrectly to describe the declining testosterone production due to ageing or simply the detection of hypogonadism in adults.

However, the truth is that late onset hypogonadism is in fact a broad clinical entity including adult-onset forms which can have an organic or functional origin and can be primary or secondary. Late onset hypogonadism is frequently diagnosed in the absence of an identifiable organic cause, and it becomes more prevalent with age. By definition LOH must comprise both persistent specific symptoms and biochemical evidence of testosterone deficiency.

The mainstay of LOH diagnosis includes signs and symptoms consistent with hypogonadism coupled with biochemical evidence of low morning total testosterone levels on two or more occasions, measured in fasting conditions.

In the history, we will take note of specific symptoms associated with hypogonadism. Symptoms can be grouped into three main categories: sexual, physical, and psychological.

Examples of sexual Symptoms include:

• Reduced libido
• Erectile dysfunction
• Fewer spontaneous erections
• Less frequent sexual activity or masturbation and
• Delayed ejaculation

Examples of Physical Symptoms are

• Reduced ability to perform vigorous activities
• Difficulty walking more than 1 kilometre
• Hot flushes
• Lower energy levels and
• Reduced physical strength

And finally, examples of Psychological Symptoms include

• Low mood
• Loss of motivation
• General fatigue
• Difficulty concentrating and
• sleep disturbances

As we can see, some of these symptoms are non-specific and need to be taken in context with the clinical and biochemical state. Also, headache and/or visual disturbance may indicate a pituitary related disorder.

As part of the physical examination, BMI and the measurement of waist circumference are strongly recommended for everyone. This is because of the strong association between hypogonadism and obesity. Testicular and penile size, as well the presence of sexual secondary characteristics can also provide useful information regarding the overall androgen status. Finally, digital rectal examination (DRE) should be performed before testosterone therapy or to support suspicion of hypogonadism where we would normally expect reduced prostatic volume.

How should we investigate male hypogonadism? The main initial test is obviously serum testosterone.

Testosterone levels are produced in a circadian variation, which may persist in ageing men. Testosterone levels are also potentially influenced by food intake therefore, serum total testosterone should be measured in fasting conditions and in the morning, usually between 07.00 and 11.00 o’clock. A confirmatory measurement should always be undertaken in the case of an abnormal value.

A testosterone of 12 nmol/L should be considered as a possible threshold for starting testosterone therapy in the presence of typical symptoms.

If abnormal total testosterone levels are found, we should check LH and FSH along with prolactin (PRL) in order to investigate possible underlying conditions and exclude possible organic causes. Let’s look at these tests individually:

FSH and LH levels can help differentiate between the diagnosis of primary or secondary hypogonadism. In primary hypogonadism, testosterone will be low and gonadotropins will be high, In secondary hypogonadism, testosterone will be low and gonadotropins will be low or inappropriately normal.

Due to its negative influence on libido, PRL should also be considered as a first-line screening test in patients with reduced sexual desire.

In addition, contrast-enhanced pituita
