Abstract
Background
Oestrogen is the primary female sex hormone and has important functions in both female and male physiology. Recently oestrogen abuse among male gym participants had raised as it is considered to enhance gym performance and breast size.
Aims
This study assesses the prevalence of oestrogen use among male gym patrons in Saudi Arabia, their practice related to oestrogen abuse, and the profiles of users.
Methods
A cross-sectional study was conducted from February 2017 to May 2017 and included 4,860 male gym patrons. The participants were given a questionnaire with a total of 19 questions regarding socioeconomic information, knowledge and practices related to oestrogen, and lifestyle habits.
Results
The participants had a mean age of 28.6+6.2 years, 6.1 per cent of them abused oestrogen, and the most common forms used were ethinylestradiol (0.03mg) and drospirenone (3mg). Furthermore, 80.7 per cent of the users used it before exercise only. Breast enlargement was the main reason for oestrogen use, and local drug stores were the main source. Compared to non-users, oestrogen users were older (P=0.322), reported lower incomes (P=0.395), were more likely to be active smokers (P=0.597), and had a longer duration of gym participation (P<0.001).
Conclusion
The results indicate that 6.1 per cent of the surveyed male participants abused a combination of oestrogen and progesterone for breast enlargement, which was significantly more likely among males who had longer durations of gym participation.
