Men and women don’t run on the same hormonal timeline.
In men, testosterone follows a rhythm that resets roughly every 24 hours. Levels are generally highest in the morning and gradually decline throughout the day and this rise is closely connected to sleep, not just the time on the clock.
In women, reproductive hormones follow a longer pattern. Across an average 28-day menstrual cycle, estrogen rises before ovulation, LH surges to trigger ovulation, and progesterone becomes dominant afterward. If pregnancy does not occur, estrogen and progesterone fall, beginning a new cycle.
One rhythm repeats daily. The other unfolds across several weeks. But neither is identical for everyone: menstrual cycles commonly vary in length, and hormone patterns are influenced by age, sleep, health, and other individual factors.
These patterns are natural and understanding them can help us work with our bodies, not against them. Individual hormone rhythms and cycle lengths may vary.
