Pate and colleagues, in an extensive review of physical activity in adolescents showed that female children and adolescents were generally less active than males [ 14 ]. If sex hormones play a role in the regulation of daily activity patterns, it is appropriate to hypothesize that male and female activity patterns would differ, especially given the cyclical nature of sex hormones in females.

In addition, female rats receiving doses of estrogen and progesterone were more likely to exert effort at gaining sexual reproduction attention from a male rat.
Due to their illness, the patients with breast cancer likely had activity patterns that were deviant from normal and therefore were not considered for this review.
Unfortunately, this article was subsequently retracted from the literature when the author admitted to fabricating the data in the study [ 30 - 32 ]. The clinical implications of expanding this research are potentially far reaching.
The human data available regarding the sex hormone effects on activity are sparse and that which exists only addresses female subjects. Emotional closeness can be an especially strong predictor of sexual motivation in females and insufficient oxytocin release may subsequently diminish sexual reproduction arousal and motivation in females.
The necessary ethical limitations of human subjects research have limited the use of such experimental manipulations in humans leading to a reduced understanding of the biological mechanisms present in humans contributing to physical activity regulations.
It is difficult to determine the possible effect of these two confounding factors on the conclusions of the currently available prospective HRT studies [ 27 , 28 ] given that none listed the recall period that was used in their studies even though the instruments used by Kenny et al.
