In a brief conversational exchange, two speakers discuss research on male testosterone levels. They note that after age 30, testosterone declines by roughly 1% per year. They also highlight a striking historical finding: about 50 years ago, the average male at any age had approximately twice the testosterone levels seen today—a 100% increase. The dialogue suggests an evolutionary shift where modern men may require less testosterone because higher estrogen levels, which regulate testosterone, have become more prevalent. When estrogen spikes, especially outside of sexual activity, testosterone tends to decrease.
