INTRODUCTION: Preventing unintended pregnancies is important among all women, including those living with HIV. Increasing numbers of women, including HIV-positive women, choose progestin-containing subdermal implants, which are one of the most effective forms of contraception. However, drug-drug interactions between contraceptive hormones and efavirenz-based antiretroviral therapy (ART) may reduce implant effectiveness. We present four inter-related perspectives on this issue. DISCUSSION: First, as a case study, we discuss how limited data prompted country-level guidance against the use of implants among women concomitantly using efavirenz in South Africa and its subsequent negative effects on the use of implants in general...

Progestin and AdipoQ Receptor 3 (PAQR3), a member of the PAQR family, is down-regulated in several types of cancers and has been closely associated with tumor progression and development. However, little is known about the functions of PAQR3 in the tumorigenesis of human glioma. Therefore, in this report, we investigated the role of PAQR3 in human glioma. Our results showed that the expression of PAQR3 was significantly reduced in human glioma tissues and cell lines. PAQR3 overexpression inhibited the proliferation of glioma cells in vitro and attenuated tumor xenograft growth in vivo...

Women experience orthostatic intolerance more than men, and experience faintness more in the early follicular (i.e. low hormone (LH)) compared to the luteal (i.e. high hormone (HH)) phase of the menstrual cycle. Men (n=13, age: 25.8±1.8) and women in the LH (day 2-5; placebo) and HH) (day 18-24; high dose) phases of the menstrual cycle with (OC; n=14, age: 22.0±0.8) or without oral contraceptives (NOC; n=12, age: 21.8±0.5) underwent the Valsalva maneuver and a supine-sit-stand protocol. Blood pressure, normalized stroke volume (SVi), cardiac output index (Qi), heart rate (HR), end-tidal carbon dioxide (ET-CO2), and middle cerebral artery blood velocity (MCA) were measured...

M1 macrophage differentiation plays a crucial role in enhanced inflammation during pregnancy, which may lead to pregnancy complications. Therefore, modulation of macrophage differentiation toward the M2 phenotype is desirable to ensure a successful pregnancy. Medroxyprogesterone acetate (MPA) is a potent progestin with an anti-inflammatory property, but its effect on macrophage differentiation is unknown. This study aimed to examine whether MPA can induce an M2 macrophage differentiation by using the human monocytes cell line THP-1 or primary monocytes...

Although progestin has been used to treat endometrial hyperplasia and endometrial carcinoma (EC), its therapeutic efficacy is limited. In order to improve this, the underlining mechanisms of the effects of progestin need to be elucidated in more detail. In the present study, we examined the involvement of mitogen-inducible gene-6 (MIG6), a negative regulator of the EGF receptor, in the progestin-mediated growth suppression of endometrial epithelia. The immunohistochemical expression of MIG6 was elevated in the early to mid-secretory phases of normal endometrium and also with endometrial hyperplasia after medroxyprogesterone acetate (MPA) therapy...

Ovarian failure occurs in most women during the late fifth decade or early sixth decade of life. This causes a number of changes in physiology as estrogen and progestin concentrations decline. These involve lipoprotein metabolism and the vasculature. The risk factors for large vessel disease increase, and dysfunction of the small resistance vessels responds with changes in blood flow to the skin causing unpleasant symptoms. These and other changes result in visits to the physician. A reassessment of risk factors and symptoms is needed to develop a new plan for effective management, both short term and long term...

Contraception services should be part of routine health care maintenance in reproductive-aged women, especially in light of the fact that approximately 50% of pregnancies in the United States remain unplanned. Barrier methods, especially condoms, may play a role in sexually transmitted disease prevention but are less efficacious for pregnancy avoidance. There are several available hormonal contraceptive options, including the combination hormonal pill, progestin-only pill, combination hormonal patches and rings, injectable progestins, implantable progestins, intrauterine devices (copper or progestin), and permanent sterilization...

BACKGROUND: Cyproterone acetate (CA) is an antiandrogenic progestin commonly used in adult transwomen to suppress endogenous androgens, often in combination with estrogens to induce feminization. AIM: To assess the (side) effects and biochemical changes of CA alone and in combination with estrogens in adolescent trans-girls. METHODS: This study was a retrospective analysis of clinical and biochemical data from 27 trans-girls who presented at Tanner stage G4 and were treated with CA monotherapy for at least 6 months (mean = 12 months) and then in combination with incremental doses of estrogens (CA + E; mean = 16 months)...

BACKGROUND: Dysmenorrhea is a common condition in women, which is characterized by menstrual pain. Low-dose estrogen/progestin combined oral contraceptives have been shown to reduce the severity of dysmenorrhea symptoms, and a 28-day cyclic regimen of ethinylestradiol/drospirenone (28d regimen) is approved for this indication in Japan. AIM: The aim of this study was to assess the safety and efficacy of a flexible extended regimen of ethinylestradiol/drospirenone (flexible regimen) in Japanese women with dysmenorrhea...

Postmenopausal hormone replacement therapy (HRT) with estrogen plus progestogens is the first line therapy to treat menopausal symptoms. The progestogen is added to estrogen to reduce or eliminate the excess risk of endometrial cancer due to the unopposed effect of estrogen. Whereas progestin clearly opposes the proliferative and deleterious long-term actions of estrogen on the endometrium, the interference of progestin on the other estrogen action remains unclear. We previously reported that chronic subcutaneous 17α-estradiol (E2) in mice decreases platelet responsiveness, prolongs the tail-bleeding time and protects against acute thromboembolism...

Apart from estrogens, the occurrence and ecotoxicity of steroids in the aquatic environment is poorly known. Here we analyzed 33 steroids, including estrogens, androgens, progestins, and glucocorticoids in hospital wastewaters, river water and in municipal wastewater treatment plant (WTP) influents and effluents at different sites in Switzerland. In addition, wastewater from different treatment steps of two WTPs with advanced treatment, such as ozonation or pulverized activated carbon, were analyzed to study the steroid's behavior during treatment...

The need to provide immediate postpartum access to intrauterine contraceptives and contraceptive implants for those who desire them is now widely acknowledged among leading healthcare organizations. The most recently updated versions of the UK, US, and World Health Organization (WHO) Medical Eligibility Criteria for Contraceptive Use (MEC) all support placement of the progestin implant, Copper IUD, and levonorgestrel IUS following delivery of the placenta and before hospital discharge. Postpartum placement has been recognized as safe, effective, and acceptable by the Royal College of Obstetricians and Gynaecologists (RCOG) and the American College of Obstetricians and Gynecologists (ACOG)...

Hypersensitivity to progestogen, previously known as autoimmune progesterone dermatitis, is an increasingly recognized clinical entity that presents specific diagnostic and treatment challenges. Clinical presentations are heterogeneous, but can consist of hypersensitivity symptoms associated with the progesterone surge during the luteal phase of the menstrual cycle or after exposure to exogenous progestins. With the increasing use of exogenous progesterone for contraception and fertility, more cases of hypersensitivity to exogenous progestins have been described...

Combined oral contraceptive (COC) use is a risk factor for venous thrombosis (VT) and related to the specific type of progestin used. VT is accompanied by inflammation and pathophysiological clot formation, that includes aberrant erythrocytes and fibrin(ogen) interactions. In this paper, we aim to determine the influence of progesterone and different synthetic progestins found in COCs on the viscoelasticity of whole blood clots, as well as erythrocyte morphology and membrane ultrastructure, in an in vitro laboratory study...

BACKGROUND: There is limited information on rates of STIs in Jamaica due to syndromic management and limited aetiological surveillance. We examined the prevalence of Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG) and Trichomonas vaginalis (TV) and characteristics associated with STIs among sexually active women who participated in a randomised trial of a progestin implant initiation in Jamaica (the Sino-Implant Study (SIS)). METHODS: SIS was a randomised trial conducted in Kingston, Jamaica, from 2012 to 2014 to evaluate whether initiation of the Sino-Implant (II) led to more unprotected sex among women ages 18-44 years...

Obesity is a prominent risk factor for endometrial cancer (EC) and can impede on surgical and hormonal treatments. Markers of EC, estrogen receptor (ER), progesterone receptor (PR), phospho(Ser473)-AKT (pAKT) and 14-3-3 sigma (14-3-3σ) were measured in EC tissues in both the tumor and stroma and grouped by body mass index (BMI). Immunohistochemical scoring of 82 cases of Type 1 and Type II EC tissues revealed a significantly increased tumor expression of ER, PR and 14-3-3σ in women with Type I (BMI < 40) as compared to Type II (BMI < 30) EC...

Due to the environmental and anthropogenic impacts that continue to threaten the reproductive success of polar bears, a more detailed understanding of their reproductive cycle is needed. Captive populations of polar bears provide an excellent opportunity to learn more about the reproductive physiology of the species. Progestin (P4) and androgen (T) metabolites in urine, and their ratio (P4:T), were examined during 11 reproductive cycles of captive female polar bears (n = 4) to characterize the steroid hormone profile during pregnancy and determine possible variations related to reproductive failure...

Estrogens have a biphasic action on pubertal and/or adolescent skeletal growth. Low levels of estrogen may increase the periosteal expansion through the increase in the sensitivity of bone for mechanical stimuli and the secretion of IGF-1. On the other hand, high estrogen concentrations may inhibit periosteal bone formation. To use OC/LEP(oral contraceptive/low dose estrogen-progestin) during adolescence, meaning exposure to high levels of estrogen, may prevent the acquisition of physiologic peak of bone mass...
