Phones that belong to the same phoneme, such as [t] and [tÊ°] for English /t/ , are called allophones. A common test to determine whether two phones are allophones or separate phonemes relies on finding minimal pairs: words that differ by only the phones in question.
Bioidentical hormone replacement therapy (BHRT), also known as bioidentical hormone therapy or natural hormone therapy, is a poorly defined term referring to the use of hormones that are identical, on a molecular level, with endogenous hormones in hormone replacement therapy.HRT is a form of alternative medicine, and has been promoted as a panacea for many diseases rather than a means of relieving the symptoms of menopause and/or reducing the risk of osteoporosis (the goals of traditional hormone replacement therapy).
Hormone Pellet Implants. Although bioidentical hormone pellets have been used since the late 1930s and are the oldest form of Bioidentical Hormone Replacement Therapy, or BHRT, many physicians are unaware that they exist. This is, in part, due to lack of FDA-approval for pellets in women (TestopelÂ® testosterone pellets are FDA approved for men).
