For males, estrogen levels should be maintained as high as possible without negative symptoms for libido, brain function, and bone health.

“you actually need both in both males and females, it's just that in females, the testosterone levels are always going to be lower than the estrogen levels, and in males, the estrogen levels are always going to be lower than testosterone levels, so testosterone promotes sex-seeking behavior, and the real question then is, does sex itself promote testosterone?”

“unless it's a problem males we're talking post-puberty um should try and have their estrogen as high as possible without having negative symptomology because of the importance of estrogen for libido for brain function tissue bone health bone health body”

“I want to remind that both men and women have testosterone. It's important in both men and women. Yes, it's related to libido. But having sufficiently high levels of estrogen in both men and women is also critical for libido.”

“However, the hormone estrogen is also strongly associated with libido and mating behavior.”

“So, it's a coordinated dance of estrogen and testosterone in both males and females that leads to libido or sex drive.”
