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).
Women produce more growth hormone than men, but growth hormone production is linked to estrogen levels. If a woman has low estrogen levels, she will also have low growth hormone. This typically occurs when women are in menopause, so growth hormone replacement therapy should include bioidentical hormone replacement of estrogen and progesterone. Most women begin to experience the signs of approaching menopause in their 40s, but it can start in a womanâs 30s or even earlier.
