Although hormone therapy is widely used by millions of women to relieve symptoms of menopause, it has been associated with several side-effects such as coronary heart disease, stroke and increased invasive breast cancer risk. These side-effects have caused many women to seek alternatives to conventional hormone therapy, including the controversial custom-compounded bioidentical hormone therapy suggested to not increase breast cancer risk. Historically estrogens and the estrogen receptor were considered the principal factors promoting breast cancer development and progression, however, a role for other members of the steroid receptor family in breast cancer pathogenesis is now evident, with emerging studies revealing an interplay between some steroid receptors...

Why compound bioidentical hormones? Are there no similar commercial products? What is unique about the options compounding pharmacists offer compared with what is out in the marketplace? These are questions that physicians and other practitioners are asking, and it is very important that we have intelligent, well-thought answers when we respond. Times have changed, and the challenges we face today in marketing our compounded therapies are not the same as those of twenty years ago. Premarin is no longer at the top of the heap, and there are topical, commercial products that contain bioidentical estradiol, and capsules that contain the same progesterone that we use...

OBJECTIVE: By the 1990s it became popular for women to use hormone therapy (HT) to ease menopause symptoms. Bioidentical estrogen and progesterone are supplements whose molecular structures are identical to what is made in the human body, while synthetic supplements are ones whose structures are not. After the Women's Health Initiative found that the combined use of the synthetics conjugated equine estrogen (CEE) and medroxyprogesterone acetate (MPA) increased breast cancer risk, prescriptions for synthetic HT declined considerably...

BACKGROUND: It is estimated that 1-2.5 million U.S. women use compounded bioidentical menopausal hormone therapy (MHT). However, the proportion of American physicians prescribing compounded bioidentical hormones remains unknown. This study aims to evaluate obstetrician-gynecologists' (OB/GYNs) and family medicine physicians' decisions reflected in prescribing practices of MHT in Kansas, and level of agreement with the American College of Obstetricians and Gynecologists (ACOG) recommendations...

Postmenopausal women with an intact uterus using estrogen therapy should receive a progestogen for endometrial protection. The debate on bioidentical hormones including micronized progesterone has increased in recent years. Based on a systematic literature review on the impact of menopausal hormone therapy (MHT) containing micronized progesterone on the mammary gland, an international expert panel's recommendations are as follows: (1) estrogens combined with oral (approved) or vaginal (off-label use) micronized progesterone do not increase breast cancer risk for up to 5 years of treatment duration; (2) there is limited evidence that estrogens combined with oral micronized progesterone applied for more than 5 years are associated with an increased breast cancer risk; and (3) counseling on combined MHT should cover breast cancer risk - regardless of the progestogen chosen...

BACKGROUND: In recent years, compounded bioidentical hormone therapy (CBHT) has emerged as a popular alternative to manufactured, FDA approved hormone therapy (HT)-despite concerns within the medical community and the availability of new FDA approved "bioidentical" products. This study aims to characterize the motivations for using CBHT in a U.S. sample of ordinary midlife women. METHODS: We analyze data collected from 21 current and former users of CBHT who participated in a larger qualitative study of menopausal decision-making among U...

Conventional hormone therapy (HT) containing estrogens such as ethinylestradiol (EE) have been associated with an increased risk of breast cancer and cardiovascular disease resulting in women seeking safer alternatives that are claimed to have fewer health risks. One such alternative gaining popularity, is custom-compounded bioidentical (b)HT formulations containing bioidentical estradiol (bE2 ) and estriol (bE3 ). However, the preparation of these custom-compounded estrogens is not regulated, and depending on the route of synthesis, steroid mixtures with differing activities may be produced...

The beneficial effects of bioidentical ovarian steroid hormone therapy (HT) during the perimenopause are gaining recognition. However, the positive effects of estrogen (E) plus or minus progesterone (P) administration to ovariectomized (Ovx) lab animals were recognized in multiple systems for years before clinical trials could adequately duplicate the results. Moreover, very large numbers of women are often needed to find statistically significant results in clinical trials of HT; and there are still opposing results being published, especially in neural and cardiovascular systems...

REVIEW
M L'Hermite
Wide rejection of conventional hormone therapy (HT) after the initial publication of the Women's Health Initiative (WHI) led to unjustified use of custom-compounded bioidentical hormones. In the USA, it became an unregulated drug manufacturer industry in disguise, without proper control and making false claims and misleading advertisements. Manufacturing quality is not ensured. Unspecific harm from compounding has occurred on a large scale, such as deaths from infected products and end-stage renal failure plus carcinoma due to confusion between different Chinese herbs...

Prenatal sex hormone levels affect physical and behavioral sexual differentiation in animals and humans. Although prenatal hormones are theorized to influence sexual orientation in humans, evidence is sparse. Sexual orientation variables for 34 prenatally progesterone-exposed subjects (17 males and 17 females) were compared to matched controls (M age = 23.2 years). A case-control double-blind design was used drawing on existing data from the US/Denmark Prenatal Development Project. Index cases were exposed to lutocyclin (bioidentical progesterone = C21H30O2; M W : 314...

The use of compounded bioidentical hormone replacement therapy by menopausal women has become a popular alternative to traditional synthetic conjugated equine estrogen and progestin hormone replacement therapy due to safety concerns raised by recent studies. However, due to the lack of randomized, large-scale trials to evaluate the efficacy and side-effect profile of compounded bioidentical hormone replacement therapy many healthcare providers are reluctant to prescribe such therapy. The purpose of this study was to compare women's menopausal symptom relief and side effects experienced when using compounded bioidentical hormone replacement therapy and traditional hormone replacement therapy...

REVIEW
M L'Hermite
The many advantages of registered bioidentical sex hormones over registered, conventional, non-bioidentical menopausal hormone therapy (MHT) are considered. The transdermal route of estrogen administration avoids excess venous thromboembolic and ischemic stroke events. There is some indication that conjugated equine estrogens are more thrombogenic and most likely induce some hypertensive responses; estradiol might also be superior to conjugated equine estrogens (CEE) in terms of global cardiovascular health...

BACKGROUND: Proponents of bioidentical estrogens claim that they are superior for treating menopausal symptoms, including depressive symptoms. Small trials examining the effects of bioidentical estrogens on depressive symptoms show conflicting results. We conducted a systematic review to assess the effectiveness and safety of bioidentical estrogens for treatment of depressive symptoms in peri- and postmenopausal women. METHODS: We searched the scientific literature for randomized controlled trials of at least 4 weeks duration, comparing bioidentical estrogen with placebo for depressive symptoms in menopausal women...

BACKGROUND: Various hormone therapies (HT) are available to treat menopausal vasomotor symptoms. Bioidentical hormones are chemically identical to those produced by the human body, and several types are well-tested and available on prescription. Many women have opted for bioidentical hormone therapy (BHT) on the assumption that it is safer than other forms of HT. We evaluated the evidence. OBJECTIVES: To determine the effectiveness and safety of bioidentical hormones compared to placebo or non-bioidentical hormones for the relief of vasomotor symptoms...
