That, coupled with the higher HIV prevalence in the population, means any sexual act has a higher chance of HIV transmission.

Women 55 and older have an increased risk of bone and muscle loss but therapy with the hormone Dehydroepiandrosterone (DHEA) may help prevent bone loss and increase muscle mass in older women, according to a new study led by Catherine M.
