EDITORIAL
Pernille Ravn, Kresten Rubeck Petersen
Long-acting, reversible contraceptives are about 20 times more effective in terms of contraceptive efficacy than oral hormonal contraceptives, patch or vaginal ring are. Long-acting, reversible contraceptives are not associated with serious adverse events but induce changes in menstrual bleeding pattern in about 75% of the users. The progestogen intrauterine device is effective in the treatment of menor-rhagia and dysmenorrhoea. Increased use of long-acting reversible contraceptives is expected to reduce unplanned pregnancies and legal abortions in all ages...

REVIEW
Pedro-Antonio Regidor, Adolf E Schindler
Data have demonstrated that COCs, besides offering a satisfactory and safe contraception, offer a variety of non-contraceptive health benefits and therapeutic positive aspects. Many prescribes and users, however, do not realize these positive aspects especially the non-contraceptive health benefits. While the contraceptive use is the primary indication for COC use for most women, these users should be advised in regard of the non-contraceptive benefits when contraception is discussed and prescribed. Using COCs specifically for non-contraceptive indications is an off-label use in many clinical situations (only some exceptions as e...

BACKGROUND: Endometrial cancer is the fourth most common cancer in European women. The major risk factors for endometrial cancer are related to the exposure of endometrium to estrogens not opposed to progestogens, that can lead to a chronic endometrial inflammation. Diet may play a role in cancer risk by modulating chronic inflammation. METHODS: In the framework of a case-control study, we recruited 297 women with newly diagnosed endometrial cancer and 307 controls from Northern Italy...

PURPOSE OF REVIEW: Transgender individuals including pubertal young people require hormonal therapy, in conjunction with mental health support. These youths are a unique population, with specific and individual desires and needs as they move through the physical and mental transition to the gender with which they identify. RECENT FINDINGS: The number of transgender youth presenting for treatment is increasing rapidly. They continue to have a high prevalence of mental health disorders, though not when supported in their sex identities by family in younger age...

PROBLEM: Medroxyprogesterone acetate (MPA), a progestin-based hormonal contraceptive designed to mimic progesterone, has been linked to increased human immunodeficiency virus (HIV-1) susceptibility. Genital epithelial cells (GECs) form the mucosal lining of the female genital tract (FGT) and provide the first line of protection against HIV-1. The impact of endogenous sex hormones or MPA on the gene expression profile of GECs has not been comprehensively documented. METHOD OF STUDY: Using microarray analysis, we characterized the transcriptional profile of primary endometrial epithelial cells grown in physiological levels of E2, P4, and MPA...

The aim of this study was to develop a reliable analytical method for the measurement of 17 selected progestogens in waste water and surface water. Automated whole water solid phase extraction (SPE) was used for sample concentration. Liquid chromatography tandem atmospheric pressure chemical ionization/atmospheric pressure photoionization with hybrid quadrupole/orbital trap mass spectrometry operated in high resolution product scan mode (LC-APCI/APPI-HRPS) was applied for the analyses. The whole-method recoveries ranged from 60% to 140% for all analytes at two different spike levels (5 and 50ng/L) in the studied matrices...

The cervix is a dynamic structure that undergoes dramatic changes during the estrous cycle, pregnancy and parturition. It is well established that hormonal changes, including estrogens, progestogens and prostaglandins, regulate the expression of key proteins involved in cervical function. The arachidonic acid cascade is important in the remodeling and relaxation of the cervix in the days preceding parturition. Despite the complexity of this mechanism, regulation of cervical function has received little study in the mare...

Despite the well-established toxicity of cadmium (Cd) to animals and the ameliorative effects of selenium (Se), some specific mechanisms in the chicken ovary are not yet clarified. To explore the mechanism by which the toxicity effect of Cd is induced and explore the effect of supranutritional Se on Cd toxicity in female bird reproduction, forty-eight 50-day-old Isa Brown female chickens were divided randomly into four groups. Group I (control group) was fed the basic diet containing 0.2 mg/kg Se. Group II (Se-treated group) was fed the basic diet supplemented with sodium selenite (Na2SeO3), and the total Se content was 2 mg/kg...

We present the case report of a patient with severe polycythaemia associated with tibolone. In our 65-year-old postmenopausal patient who initially presented with haemoglobin 203 g/L [115-160] and haematocrit 0.63 [0.32-0.47], the cessation of tibolone, a synthetic hormone replacement therapy, led to a dramatic and sustained resolution of this patient's polycythaemia to normal haematological values. Tibolone possesses oestrogenic, androgenic, and progestogenic properties. Tibolone therapy may be an infrequently recognized contributor towards polycythaemia in postmenopausal patients presenting to haematology clinics...

BACKGROUND: Cyproterone acetate 2 mg/ethinylestradiol 35 µg, an estrogen/progestogen treatment with anti-androgenic properties, shares a thromboembolism risk with combined hormonal contraceptives. Educational materials (i.e., direct healthcare professional communication, patient information card, prescriber checklist) were distributed to physicians to increase risk awareness. OBJECTIVE: The objective of this study was to measure physician knowledge of thromboembolism risk of cyproterone acetate 2 mg/ethinylestradiol 35 µg and ascertain whether physicians received the educational materials...

Although fixed-time artificial insemination (FTAI) protocols are available for sheep, estrus resynchronization has not been previously reported. The objectives of this study were to evaluate the effect of estrus resynchronization with exogenous progestogen on endogenous progesterone levels and to compare pregnancy rates after two consecutive estrus synchronizations in ewes. In Experiment 1, ewes (n = 20) received an intravaginal device (IVD) containing 60 mg medroxyprogesterone acetate (MPA) for 10 days...

BACKGROUND: The progestogen 17-alpha hydroxyprogesterone caproate is 1 of only 2 agents recommended for clinical use in the prevention of spontaneous preterm delivery, and studies of its efficacy have been conflicting. We have developed an in vitro model to study the fetal membrane weakening process that leads to rupture in preterm premature rupture of the fetal membranes. Inflammation/infection associated with tumor necrosis factor-alpha induction and decidual bleeding/abruption associated thrombin release are leading causes of preterm premature rupture of the fetal membranes...

Sulfonated steroids (s-St) have been usually regarded as inactive metabolites but are progressively considered as precursors for the intra-tissue formation of bioactive steroids. Moreover, independent effects without preceding removal of the sulfate group have been observed. We use the porcine testicular-epididymal compartment as a model to investigate the still largely unknown s-St physiology as the boar exhibits an intriguingly broad s-St spectrum predominantly originating from the testis. The application of LC-MS/MS in steroidomics enables the determination of unconjugated and intact sulfonated steroids with currently highest specificity and good sensitivity, allowing the concurrent measuring of numerous analytes in larger quantities of samples...

Steroids have an important role in growth, development, sexual differentiation and reproduction. All four classes of steroids, androgens, estrogens, progestogens and glucocorticoids, have varying effects on the brain. Androgens and estrogens are involved in the sexual differentiation of the brain, and also influence cognition. Progestogens such as progesterone and its metabolites have been shown to be involved in neuroprotection, although their protective effects are timing dependent. Glucocorticoids are linked with stress and memory performance, also in a dose- and time-dependent manner...

Perimenopause marks a period of increased migraine prevalence in women and many women also report troublesome vasomotor symptoms. Migraine is affected by fluctuating estrogen levels with evidence to support estrogen 'withdrawal' as a trigger of menstrual attacks of migraine without aura, while high estrogen levels can trigger migraine aura. Maintaining a stable estrogen environment with estrogen replacement can benefit estrogen-withdrawal migraine particularly in women who would also benefit from relief of vasomotor symptoms...

In the last decade the risk benefits ratio of HRT has been reevaluated mainly in tens of cardiovascular risk. Present Consensus Statement is largely inspired by the Global Consensus on Menopausel Hormone Therapy in 2013 and 2016 by leading global menopause societies (The American Society for Reproductive Medicine, The Asia Pacific Menopause Federation, The Endocrine Society, The European Menopause and Andropause Society, The International Menopause Society, The International Osteoporosis Foundation and The North American Menopause Society)...

The aim of this study was to assess the adverse effects of synthetic progestin norgestrel (NGT) on the reproduction of zebrafish by measuring the egg production, histology and transcriptional expression profiles along the hypothalamic-pituitary-gonadal (HPG) axis in adult zebrafish. After a pre-exposure period of 7 days, adult zebrafish were exposed to 6, 29 and 69 ng L(-1) NGT for 21 days. The results showed that exposure to 69 ng L(-1) NGT led to a significant up-regulation of follicle stimulating hormone, beta polypeptide (fshb), luteinizing hormone, beta polypeptide (lhb), progesterone receptor (pgr), estrogen receptor 1 (esr1) and androgen receptor (ar) genes in the brains, as well as significant up-regulation of hydroxysteroid 20-beta dehydrogenase (hsd20b) and hydroxysteroid 11-beta dehydrogenase 2 (hsd11b2) genes and down-regulation of 11-beta-hydroxylase (cyp11b) gene in the ovaries of females...
