Estrogen helps reduce the rate of bone loss that occurs during normal bone remodeling. Normally there is a balance in the activity of the cells that break down bone and the cells that build it back up. By decreasing the activity of the cells that break down bone, estrogen allows the cells that build bone to have a greater overall effect. Once estrogen levels drop, this balance shifts.
While hormone therapy has been shown to decrease hip and vertebral fractures, it may also increase your risk of other health conditions, such as invasive breast cancer, stroke and blood clots. Discuss the risks and benefits of available treatments with your health care professional.
Little research has been conducted on the effect of hormones on reproduction motivation for same-sex sexual contact. One study observed the relationship between sexual reproduction motivation in lesbian and bisexual women and period-related changes in circulating estrogen concentrations.  Lesbian women who were at the estrogen peak of their fertile cycle reported increased reproduction motivation for sexual contact with women, whereas bisexual women reported only a slight increase in same-sex motivated sexual contact during peak estrogen levels. Interestingly, both lesbian and bisexual women showed decreases in reproduction motivation for other-sex sexual contact at peak estrogen levels, with greater changes in the bisexual group than the lesbian group.
It is also suggested that there is an interaction between hormone levels and eating at different points in the female menstrual cycle . Research has predicted increased emotional eating during hormonal flux, which is characterized by high progesterone and estradiol levels that occur during the mid- luteal phase . It is hypothesized that these changes occur due to brain changes across the menstrual cycle that are likely a genomic effect of hormones. These effects produce menstrual cycle changes, which result in hormone release leading to behavioral changes, notably binge and emotional eating. These occur especially prominently among women who are genetically vulnerable to binge eating phenotypes.
