Ok — I wonder if 99% the difference between men and women has to do with a menstrual cycle., the “mens” cycle, or “menses”— even ancient Plutarch in around 60 SD (60 years after the death of Jesus) wrote this—

Highest testosterone in morning

Testosterone levels in men are typically highest in the morning. This is due to the endocrine system’s regulatory patterns, which follow a circadian rhythm. The peak is usually observed in the early morning hours, with levels gradually declining throughout the day to reach their lowest point in the evening. This diurnal variation is why blood samples for testosterone testing are often recommended to be taken in the morning, to ensure consistency and accuracy in measuring the baseline levels of this hormone.The morning peak in testosterone levels is believed to be linked to the sleep-wake cycle and is more pronounced in younger men. As men age, the magnitude of diurnal variation in testosterone levels tends to decrease, but the pattern of higher morning levels generally remains.This circadian rhythm of testosterone is thought to be regulated by the hypothalamus and pituitary gland, which respond to the body’s internal clock to modulate the release of hormones. The exact mechanism and all influencing factors are complex and subject to ongoing research, but the morning peak is a consistent finding in studies of male testosterone levels.

Does male testosterone fluctuate monthly cycle

Yes, male testosterone levels can fluctuate over different time scales, including daily (with higher levels in the morning) and potentially over longer periods such as monthly cycles, though this is less well-studied and understood than the daily rhythm. Research indicates that there are variations in testosterone levels due to various factors including age, physical activity, sleep patterns, and stress levels. However, the concept of a regular monthly cycle in men, akin to the menstrual cycle in women, is not widely supported by current scientific evidence.Men’s testosterone levels can vary significantly from day to day and throughout the day. The most well-documented pattern is the diurnal variation, where testosterone levels are highest in the morning and gradually decrease throughout the day. This pattern is more pronounced in younger men.While there’s ongoing research into hormonal cycles in men and how they might parallel some aspects of hormonal cycles in women, the evidence for a strict monthly cycle in testosterone levels in men is not conclusive. Variations in testosterone levels are more commonly linked to broader health and lifestyle factors rather than a cyclical monthly process.It’s also important to note that individual differences play a significant role in hormone levels and their fluctuations. Some men might experience more noticeable fluctuations in mood, energy, and other factors that could be hormonally influenced, but linking these changes directly to a consistent monthly cycle requires more scientific study.
