Sexual health is a state of physical, mental and social well-being in relation to sexuality (WHO 2019a). Measures of sexual health include the prevalence of sexual difficulties and sexually transmissible infection rates.
Sexually transmitted infections
Sexually transmitted infections (STIs) are a subset of communicable diseases known to be transmitted through sexual contact. More than 30 different viruses, bacteria and parasites are known to be transmitted sexually (WHO 2019b). While some STIs can be cured, a person can have an STI without symptoms of disease. If left untreated, these infections can have serious consequences for long-term health.
In Australia, data about new cases of STIs are collected through notifiable disease monitoring systems. Data about common infections are routinely published in annual surveillance reports, including chlamydia, gonorrhoea, syphilis, hepatitis B, hepatitis C and HIV (Kirby Institute 2018).
84,436
new cases of selected notifiable STIs were reported for Australian males in 2017
In 2017, males accounted for more than half (56%) of all new STI cases (Kirby Institute 2018).

Notification rates for viral hepatitis and HIV have remained stable over time in males. However, there has been an increase in rates of chlamydia, gonorrhoea and syphilis notifications. Compared with 2008, rates of these infections in 2017 for males were:
- 4 times as high for gonorrhoea
- 3 times as high for syphilis
- almost twice as high for chlamydia.

Sexual difficulties
More than 1 in 2
Australian men have experienced at least 1 sexual difficulty in the last 12 months
According to self-reported data, more than half (54%) of men aged 18–55 had experienced some sexual difficulty lasting at least 3 months in the last 12 months. Of these men (Schlichthorst et al. 2016):
- around 2 in 5 (37%) reported ‘reaching climax too quickly’
- around 1 in 5 (17%) ‘lacked interest in having sex’.
‘Reaching climax too quickly’ was the most common issue across all age groups (between 32% and 39%).
Other types of sexual difficulty differed by age:
- ‘did not reach climax or took a long time’ was the next most common issue in men aged 18–24
- ‘lacking interest in having sex’ was most common among men of other age groups (25–34, 35–44 and 45–55).
