It's a common misconception that female bodybuilders don't have periods. However, this isn't the case! In fact, most women who lift weights and engage in regular strength training do continue to experience monthly menstruation.
There are a few reasons why some people may think that female bodybuilders don't have periods. One is that often times, when women are engaging in intense physical activity, their menstrual cycles can be disrupted or even halted altogether. This is known as amenorrhea and it's relatively common among athletes of all types (not just bodybuilders!). It can occur for a variety of reasons, including low body fat percentage, stress, and overtraining.
Another reason why some people may think that female bodybuilders don't have periods is because many of them use anabolic steroids. These drugs can interfere with normal hormone production and prevent the ovaries from releasing eggs (which is necessary for menstruation to occur). However, not all female bodybuilders use steroids and even those who do may still experience monthly bleeding.
So, to answer the question: yes, female bodybuilders can have periods!
