Hormone by genotype interactions have been widely ignored by cognitive neuroscience. Yet, the dependence of cognitive performance on both baseline dopamine (DA) and current 17ß-estradiol (E2) level argues for their combined effect also in the context of reinforcement learning. Here, we assessed how the interaction between the natural rise of E2 in the late follicular phase (FP) and the 40 base-pair variable number tandem repeat polymorphism of the dopamine transporter (DAT1) affects reinforcement learning capacity...

The available literature, from 2006 to 2017, on hormonal treatment has been analysed as a contribution to the HAS-CNGOF task force for the treatment of endometriosis. Available data are heterogeneous and the general level of evidence is moderate. Hormonal treatment is usually offered as the primary option to women suffering from endometriosis. It cannot be used in women willing to conceive. In women who have not been operated, the first line of hormonal treatment includes combined oral contraceptives (COC) and the levonorgestrel-releasing intra uterine system (52mg LNG-IUS)...

Catamenial epilepsy, defined as the exacerbation of the frequency of seizures in a given phase of the menstrual cycle, affects 35% of women. In women with catamenial epilepsy with perimenstrual seizures, progesterone therapy may be effective. In case of enzyme inducer AEDs, hormonal contraception is deprecated (estroprogestative or progestative pill, progestative implant, patches or hormonal rings). Because of its high malformative teratogenic potential, its possible depressive cognitive effects and the autistic risk, sodium valproate is not indicated during pregnancy...

Major advances in menopause hormone therapy (MHT) hold promise in the future of better and safer care for women at and after the menopause. The principal advances are: (1) the critical window or 'window of opportunity' in the 10 years or so after the menopause, during which the benefits of MHT in healthy women exceed any risks; (2) use of transdermal instead of oral administration of estrogen to reduce the risk of venous thromboembolism; (c) investigation of the use of oral micronized progesterone (MP) and vaginal MP to prevent endometrial hyperplasia and carcinoma without any increased risk of breast cancer and venous thromboembolism in postmenopausal women receiving estrogens; vaginal MP prevents endometrial proliferation in the short term but the long-term effects in MHT remain to be established; (4) investigation into the use of intrauterine levonorgestrel-releasing devices (LNG-IUDs), which are an attractive form of MHT in perimenopausal women, providing contraception and reducing uterine bleeding, although the risk of breast cancer with LNG-IUDs requires clarification...

Estradiol production varies cyclically, changes in levels are hypothesized to affect the voice. The main objective of this study was to investigate vocal acoustic and auditory-perceptual characteristics during fluctuations in the levels of the hormone estradiol during the menstrual cycle. A total of 44 volunteers aged between 18 and 45 were selected. Of these, 27 women with regular menstrual cycles comprised the test group (TG) and 17 combined oral contraceptive users comprised the control group (CG). The study was performed in two phases...

With fewer than 200 reported cases, Cushing's syndrome (CS) in pregnancy remains a diagnostic and therapeutic challenge. In normal pregnancies, misleading signs may be observed such as striae or hypokalemia, while plasma cortisol and urinary free cortisol may rise up to 2-3-fold. While the dexamethasone suppression test is difficult to use, reference values for salivary cortisol appear valid. The predominant cause is adrenal adenoma (sometimes without decreased ACTH), rather than Cushing's disease. There are considerable imaging pitfalls in Cushing's disease...

Managing contraception for women at high risk for thrombosis poses unique challenges. Combined estrogen and progestin contraceptives increase the risk of both venous and arterial thrombosis. They are contraindicated in women with a history of thrombosis and in other women at high risk for thrombosis. However, progestin-only contraceptives are generally considered safe in this patient population. This paper reviews the evidence linking hormonal contraception and clotting risk, outlines appropriate contraceptive methods for women at high risk for thrombosis, discusses surgical risk for sterilization in the setting of current or past thrombosis, and includes a review of the safety of hormonal methods for women who are fully anticoagulated...

Migraine is a common, disabling and incapacitating headache disorder that may be triggered by many factors, such as hormones especially during the perimenopausal period, where large alterations in estradiol levels can occur. The evidence implies that hormonal fluctuations are one of the important triggers of migraine. During reproductive life and during hormonal contraception, the course of migraine can be impacted. Different types of migraine with and without aura can be variously influenced by hormones. Migraine can constitute a risk factor for stroke and this must be taken in account for menopause hormone therapy...

Hormonal contraception is being increasingly used to manage captive animals in zoological collections. Many of the animals placed on contraception are of genetic importance within captive breeding programs; therefore, it is imperative that the application of contraceptive products minimize potential side effects and facilitate a return to fertility if required. Deslorelin acetate implants (Suprelorin®) are one example of a hormonal contraceptive that is frequently used in captivity as they are easy to use and effective in most species...

Evidence suggests that females experience adaptive shifts in facial preferences across the menstrual cycle. However, recent discussions and meta-analyses suggest that these findings are equivocal. A previously unexplored question is the extent to which shifts in female preferences are modulated by hormone-dependent changes occurring in low-level vision, such as visual sensitivity. This mechanistic approach has been a novel method for investigating the extent to which complex perceptual phenomena are driven by low-level versus higher-level perceptual processes...

17α, 20β-dihydroxypregn-4-en-3-one (17α, 20β-DP, DHP), a teleost specific biologically active progestin, has been proved to play a critical role in oocytes maturation, ovulation and spermiation. RU486 (Mifepristone, an antagonist of progestin receptor) has been applied in contraceptives, abortion and hormone therapy in clinical medicine. To get further insights into the molecular mechanisms of nuclear progestin receptor (Pgr) activated ovarian differentiation and maintenance, we conducted comparative gonadal transcriptome analysis, and investigated histological and transcriptional differences using 4 mah (month after hatching) RU486-treated XX and control XX/XY Nile tilapia (Oreochromis niloticus)...

BACKGROUND/OBJECTIVES: Plasma steroid hormone levels vary between men and women, but their associations with BMI and adiposity are controversial. Furthermore, little is known about the role of exercise programs on the relationship between steroid hormones and adiposity. This report evaluates these relationships for plasma levels of adrenal, gonadal, and conjugated steroids with body composition and fat distribution in sedentary men and women, aged 17-65 years, and their responses to an exercise program...

BACKGROUND: Despite increasing contraceptive availability, unintended pregnancy remains a global problem. Developing strategies to reverse this trend and increasing occurrence of withdrawal syndrome among newborn children of females currently injecting drugs warrants special attention. The knowledge base on the uptake of effective contraception among females who inject drugs (FWID) is scant. We aimed to examine the prevalence of and factors associated with the use of non-condom contraceptives among sexually active FWID with the focus on effective contraception...

BACKGROUND: Data evaluating the impact of contraceptives on the vaginal microbiome are limited and inconsistent. OBJECTIVE: We hypothesized that women initiating copper intrauterine device use would have increased bacterial vaginosis and bacterial vaginosis-associated microbes with use compared to women initiating and using hormonal contraceptive methods. STUDY DESIGN: Vaginal swabs (N=1047 from 266 participants seeking contraception) for Nugent score determination of bacterial vaginosis (BV) and quantitative polymerase chain reaction analyses for assessment of specific microbiota were collected from asymptomatic, healthy women aged 18-35 in Harare, Zimbabwe who were confirmed to be free of non-study hormones by mass spectrometry at each visit...

The management of endometriosis related infertility requires a global approach. In this context, the prescription of an anti-gonadotropic hormonal treatment does not increase the rate of non-ART (assisted reproductive technologies) pregnancies and it is not recommended. In case of endometriosis related infertility, the results of IVF management in terms of pregnancy and birth rates are not negatively affected by the existence of endometriosis. Controlled ovarian stimulation during IVF does not increase the risk of endometriosis associated symptoms worsening, nor accelerate the intrinsic progression of endometriosis and does not increase the rate of recurrence...
