I know that girls have hormonal fluctuations based on the menstrual cycle. Do guys' hormones fluctuate regularly as well?

Not on a monthly basis. Testosterone (T) is released in pulses, but these are usually on the hourly to daily timescale. There's some slight fluctuation over the course of a year, but nothing major. The amount of T also decreases with age, which some call andropause (or colloquially known as manopause). T will also decrease after a male becomes a father. Male hormonal release is known as tonic release instead of the female cyclical release.
