Next-line treatment for primary male hypogonadism when lifestyle modification fails to raise serum testosterone
In primary male hypogonadism, the initial step is non-pharmacological: improving lifestyle, reducing weight in obesity, and treating comorbidities. When this approach does not produce a significant increase in serum testosterone, a pharmacological protocol becomes the appropriate next step.
Prior treatment — target not achieved
The first-line intervention — lifestyle improvement, weight reduction where obesity is present, and management of comorbidities — did not achieve a significant increase in serum testosterone levels. This protocol addresses that clinical gap.
Next-line approach (partial overview)
Testosterone replacement therapy is the intervention at this stage. Several preparation forms are available. Short-acting preparations are generally preferred at treatment initiation, allowing early detection of any adverse effects. The complete structured regimen — including preparation selection, administration schedule, and monitoring plan — is available in the full protocol.
Clinical target
Restore serum testosterone to the mid-normal range, with treatment response assessed at three, six, and twelve months after starting therapy.

- The available agents are oral preparations, intramuscular injections and transdermal gel.
- Short-acting preparations are preferred to long-acting depot administration in the initial treatment phase, so that any adverse events that may develop can be observed early and treatment can be discontinued if needed.
- Expert opinion suggests that testosterone treatment should restore the serum testosterone level to the mid-normal range of specific age groups of men, which is usually sufficient to alleviate various manifestations of hormone deficiency.
- Assess the response to testosterone treatment at three, six and twelve months after the onset of treatment, and thereafter annually.
