Wei Xue, Yan Deng, Yan-Fang Wang, Ai-Jun Sun
BACKGROUND: Menopausal hormone therapy (MHT) has been proven to have beneficial effects on several components of metabolic syndrome. However, the effects vary according to different regimens, dosages, and duration of MHT. The aim of the study was to evaluate the effect of standard-dose 0.625 mg conjugated equine estrogen (CEE) and half-dose 0.3 mg CEE daily with different progestogens in a continuous sequential regimen on postmenopausal metabolic parameters in generally healthy postmenopausal women...

Over time, it became evident that with the use of micronized progesterone and dydrogesterone prevention or treatment of pregnancy disorders such as threatened miscarriage, recurrent (habitual) miscarriage, preterm labor or preeclampsia appears to be possible. The results so far obtained will be delineated and concepts of prevention or treatment are suggested with the aim to further explore these pregnancy disorders either by prevention or treatment concepts to obtain not only benefits to the mother and the fetus, but furthermore this results in benefits for lifetime for the individual, for the family and last but not least for society...

Today, it is a mandatory practice to prescribe a combination of estrogens and progestogens for menopausal women requiring hormone therapy and with a uterus. The WHI study and its reanalysis demonstrate a big difference in results between the conjugated equin estrogen (CEE) only vs.CEE plus medroxyprogesterone acetate (MPA) arms in relation with breast cancer and cardiovascular risk. The conclusion is that risk is clearly higher in the arm with MPA than in the CEE only arm. Although the only progestogen used in the WHI study was medroxyprogesterone acetate, side effects and intolerance have been extrapolated as a class effect to all progestogens...

BACKGROUND: Miscarriage is a common complication of pregnancy occurring in 15-20 % of all clinically recognized pregnancies. Currently, there is still no good scientific evidence to support the routine use of progestogens for the treatment of threatened miscarriage because the existing studies were not large enough to show a significant difference and some of them were not randomized or double-blind. METHODS: This is a double-blind, randomized controlled trial...

The presented clinical example convincingly demonstrates the efficacy of dydrogesterone (30 mg) in the prevention of severe preeclampsia in a high-risk patient (early development of preeclampsia and preterm Cesarean section in her first pregnancy, arterial hypertension). This case suggests using dydrogesterone as an option to prevent preeclampsia, as previously shown in a prospective randomized study.

The effects of some progestins on fish reproduction have been recently reported revealing the hazard of this class of steroidal pharmaceuticals. However, their effects at the central nervous system level have been poorly studied until now. Notwithstanding, progesterone, although still widely considered primarily a sex hormone, is an important agent affecting many central nervous system functions. Herein, we investigated the effects of a large set of synthetic ligands of the nuclear progesterone receptor on the glial-specific expression of the zebrafish brain aromatase (cyp19a1b) using zebrafish mechanism-based assays...

CONTEXT: The "window of opportunity hypothesis" refers to data indicating that conjugated equine estrogen alone or in combination with medroxyprogesterone acetate, if initiated before 60 years of age, protects the heart but endangers it if initiated later (Women's Health Initiative study). Less is known about the "window of opportunity hypothesis" with natural estradiol alone (ET) or with various progestins in combination with estradiol (EPT). OBJECTIVE: We related the death risk from coronary heart disease (CHD) in users of ET or EPT to the age at the initiation of therapy and to the progestin component of EPT...

INTRODUCTION: Gestational hypertension remains one of the main causes of maternal deaths all over the world. Attempts to reduce/prevent the incidence had failed due to lack of understanding of the disease's aetiology. One of the early roles of natural progesterone in the first trimester of pregnancy is to promote formation of wide-calibre spiral vessels that invade into the myometrial layer of the gravid uterus. Theoretically, this will prevent or reduce the incidence of gestational hypertension in the latter half of the pregnancy...

INTRODUCTION: Assisted reproductive techniques (ARTs) result in a deficient luteal phase, requiring the administration of exogenous progesterone intramuscularly, intravaginally or orally. Dydrogesterone, an oral retroprogesterone, has good bioavailability; it has been used in assisted reproductive cycles with outcomes comparable to those of vaginal or intramuscular progesterone. However, there are limited reviews on the use of dydrogesterone for luteal phase support in ARTs in terms of pregnancy outcomes and associated fetal anomalies...

Oral administration of dydrogesterone during second half of menstrual cycle has been shown to reduce menstrual irregularities. This prospective, observational study aimed to determine continued effectiveness of dydrogesterone (prescribed between 1 and 6 cycles or longer) in menstrual cycle regularization in Indian women aged ≥18 years with irregular menstrual cycle for at least 3 months. Those achieving regular cycles (21 to 35 days, inclusive) during treatment were followed up for 6 months after cessation of dydrogesterone treatment...

Despite potential exposure of aquatic organisms to mixtures of steroid hormones, very little is known on their joint activity in fish. Drospirenone (DRS) is a new synthetic progestin used in contraceptive pills in combination with 17α-ethinylestradiol (EE2). Here we systematically analyzed effects of DRS in binary mixtures with progesterone (P4) and EE2. First, we determined the in vitro activity of single compounds in recombinant yeast assays that express the human progesterone, androgen, or estrogen receptor, followed by determination of mixture activities of DRS and P4, DRS and EE2, as well as medroxyprogesterone acetate (MPA) and dydrogesterone (DDG)...
