Evidence on the effects of hormonal contraceptives on female sexuality is conflicting. We enrolled 556 women, divided into six groups: two composed of subjects using a combined hormonal contraceptive (COC) containing 0.020 ("COC20") and 0.030 ("COC30") mg of ethynyl estradiol (EE), "natural", using COC containing 1.5 mg of estradiol (E2), "ring", using a vaginal ring releasing each day 0.015 mg of EE + 0.120 of etonogestrel, "subcutaneous", using a progestin only subcutaneous contraceptive implant releasing etonogestrel and "controls", using no hormonal contraceptive methods...

Synthetic progestins act as endocrine disrupters in fish but their risk to the environment is not sufficiently known. Here, we focused on an unexplored antiandrogenic progestin, chlormadinone acetate (CMA), and the antiandrogenic progestin cyproterone acetate (CPA). The aim was to evaluate whether their in vitro interaction with human and rainbowfish (Melanotaenia fluviatilis) sex hormone receptors is similar. Furthermore, we investigated their activity in zebrafish (Danio rerio) eleuthero-embryos. First, we studied agonistic and antagonistic activities of CMA, CPA, and 17α-ethinylestradiol (EE2), in recombinant yeast expressing either the human progesterone (PGR), androgen (AR), or estrogen receptor...

CONTEXT: There are conflicting data on postmenopausal hormone therapy (HT) and the risk of vascular dementia (VD) and Alzheimer's disease (AD). OBJECTIVE: We analyzed the mortality risk attributable to VD or AD in women with a history of HT use. Design, Patients, Interventions and Main Outcome Measures: A total of 489,105 Finnish women using systemic HT in 1994-2009 were identified from the nationwide drug reimbursement register. Of these women, 581 died of VD and 1057 of AD in 1998-2009...

Hereditary angioedema with normal C1 esterase inhibitor and mutations in the F12 gene (HAE-FXII) is associated with skin swellings, abdominal pain attacks, and the risk of asphyxiation due to upper airway obstruction. It occurs nearly exclusively in women. We report our experience treating HAE-FXII with discontinuation of potential trigger factors and drug therapies. The study included 72 patients with HAE-FXII. Potential triggers included estrogen-containing oral contraceptives (eOC), hormonal replacement therapy, or angiotensin-converting enzyme inhibitors...

PURPOSE: Hysteroscopic surgery is considered the gold standard for the minimal invasive treatment of many endouterine diseases such as endometrial polyps or submucous myomas. Recently, many studies have evaluated the effect of preoperative administration of a number of drugs to reduce endometrial thickness and achieve important intraoperative advantages. The purpose of this systematic review is to summarize the available evidence about the use of Dienogest, an orally administrable progestin, for endometrial preparation before hysteroscopic surgery...

OBJECTIVE: To investigate safety of hormonal contraception with regard to thromboembolic events in women with type 1 or 2 diabetes. RESEARCH DESIGN AND METHODS: We used data from 2002-2011 in Clinformatics Data Mart to identify women in the U.S., 14-44 years of age, with an ICD-9-CM code for diabetes and a prescription for a diabetic medication or device. We examined contraceptive claims and compared time to thromboembolism (venous thrombosis, stroke, or myocardial infarction) among women with diabetes dispensed hormonal contraception using a modification of Cox regression to control for age, smoking, obesity, hypertension, hyperlipidemia, diabetic complications, and history of cancer; we excluded data for 3 months after women gave birth...

The growing popularity of levonorgestrel (LNG)-releasing intra-uterine systems for long-acting reversible contraception provides strong impetus to define immunomodulatory properties of this exogenous progestin. In initial in vitro studies herein, we found LNG significantly impaired activation of human dendritic cell (DCs) and their capacity to promote allogeneic T cell proliferation. In follow-up studies in a murine model of intranasal Chlamydia trachomatis infection, we analogously found that LNG treatment prior to infection dramatically reduced CD40 expression in DCs isolated from draining lymph nodes at 2 days post infection (dpi)...

INTRODUCTION: Oral contraceptive pills have been implicated in the pathophysiology of breast cancer. Although many studies have examined the relationship between combined oral contraceptives (COCs) and breast cancer, there is a paucity of literature that discusses progestin-only oral contraceptives (POCs) and breast cancer. The purpose of this investigation is to examine potential associations between different types of oral contraceptives and breast cancer mortality in the South Carolina Medicaid population among different racial/ethnic groups...

Drospirenone (DRSP) is an antialdosterone agent with progestogenic and antiandrogenic effects. This compound, has been recently used in combination with 17β-estradiol (E2) as hormonal therapy in postmenopausal women and has been shown to exert a significant antihypertensive effect in hypertensive post-menopausal women. Aim of the present study was to compare the effect of DRSP/E2 with those of Tibolone (T) on endothelial function, arterial stiffness, and lipid profile of early postmenopausal women naïve on post-menopausal hormonal therapy...

Hormonal contraception is central in the prevention of unintended pregnancy; however there are concerns that certain methods may increase the risk of HIV acquisition and transmission. Hormonal contraceptives may modify the genital mucosa in several ways, however the mechanisms are incompletely understood. Few studies have examined genital HIV shedding prospectively before and after initiation of hormonal contraception. The effects of hormonal contraception on genital HIV shedding in the setting of antiretroviral therapy (ART) are also unknown...

Nestorone® (NES) is a highly potent non-androgenic progestin being developed for contraception. NES is a synthetic progestin that may possess neuroprotective and myelin regenerative potential as an added health benefits. In receptor transactivation experiments, NES displayed greater potency than progesterone to transactivate the human progesterone receptor (hPR). This was confirmed by docking experiments which revealed that NES adopts the same docking position within the PR ligand-binding domain (LBD) as progesterone and forms additional stabilizing contacts between 17α-acetoxy and 16-methylene groups and PR LBD supporting its higher potency than progesterone...

We audited the files of 114 postmenopausal women who had been treated with subcutaneous Estrapel (50mg oestradiol implants). Of the 92 women who received more than one implant, the median number of days between implants was 223.5 (range 49-875), with an estimated median time to return to baseline of 311days (range 108-1228). Although oestradiol implants can provide an excellent non-oral treatment option, their prolonged action makes patient selection important, as the implants cannot easily be removed. In women with an intact uterus, the continuation of progestin therapy after cessation of implant therapy is imperative...

REVIEW
Anuja Dokras
The use of steroid sex hormones for noncontraceptive benefits has been endorsed by several medical societies. In women with polycystic ovary syndrome (PCOS), hormonal contraceptives are first-line therapy for concurrent treatment of menstrual irregularity, acne, and hirsutism. The association of PCOS with obesity, diabetes, and dyslipidemia frequently brings up the debate regarding risks versus benefits of hormonal contraceptives in this population. In women with PCOS, the lack of large-scale studies evaluating the risks with varying doses of ethinyl estradiol, types of progestins, and presence of confounding factors such as obesity, smoking, and other cardiometabolic comorbidities is a significant limitation in these deliberations...

Endometriosis is characterized by frequent recurrences of symptoms and lesions even after extirpative surgery. Because medical therapies control but do not cure the disease, long periods of pharmacologic management may be needed until pregnancy desire or, sometimes, physiologic menopause. Hormonal drugs suppress ovulation and menstruation and have similar beneficial effects against pain. However, only estrogen-progestins and progestins have safety/tolerability/cost profiles that allow long-term use. These compounds induce atrophy of eutopic and ectopic endometrium, have antiinflammatory and proapoptotic properties, and can be delivered via different modalities, including oral, transdermal, subcutaneous, intramuscular, vaginal, and intrauterine routes...

During their lives, women go through three different phases during which sex hormones play a fundamental role in contributing to specific cardiovascular and coronary risks. To evaluate this risk, we must take into account these various phases with their associated cardiovascular risk factors, and this during three key steps: contraception, pregnancy and menopause. Arterial risk linked to estrogen combined with progestin contraception, depends on the dosage of estrogen. The main cardiovascular risk factor responsible for increasing the risk of myocardial infarction is tobacco, especially after 35 years of age, contraindicating estrogen combined with progestin contraception at the benefit of progestin...

BACKGROUND: Oral use of exogenous estrogen/progestin alters hemostatic factor levels. The influence of endogenous hormones on these levels is incompletely characterized. OBJECTIVES: Our study aimed to test whether, among postmenopausal women, high levels of estradiol (E2), estrone (E1), testosterone (T), dehydroepiandrosterone-sulfate (DHEAS), DHEA, and androstenedione, and low levels of sex hormone-binding globulin (SHBG), are positively associated with measures of thrombin generation (TG), normalized activated protein C sensitivity ratio (nAPCsr), and factor VII activity (FVIIc), and negatively associated with antithrombin activity (ATc) and total protein S antigen (PSAg)...
