Even before a man has opened his eyes in the morning, his level of testosterone is at its peak – between 25% to 50% more than at any other time of the day.
That’s because the pituitary gland in his brain – which governs the production of the male S3@. Xx:’ hormone – has been switched on in the night and levels have been steadily rising until dawn.
Women also make testosterone – the main S3@. Xx:’ drive hormone – but produce a fraction of the amount and it rises by only a tiny bit overnight. It is also kept in balance by oestrogen and progesterone.

Slept well? A good kip is another reason a man may feel even more amorous in the morning. Studies found the longer and deeper a man has slept, the higher his testosterone levels. Research in the Journal of the American Medical Association shows getting more than five hours’ sleep can raise male levels by an extra 15%.

While a man’s levels of S3@. Xx:’ hormones are at their highest when he wakes up, a woman’s are at their lowest. “Male and female testosterone levels are at their highest at opposite ends of the day, so they are out of synch,” says consultant gynaecologist Gabrielle Downey, of the Sandwell and West Birmingham Hospitals NHS Trust.
