BACKGROUND: The spacing of pregnancies has a positive impact on maternal and newborn health. The progestin contraceptive implant, which is a long-acting, reversible method of contraception, has a well-established low failure rate that is compatible with tubal sterilization. The standard provision of contraceptive methods on the first postpartum visit may put some women at risk of unintended pregnancy, either due to loss to follow-up or having sexual intercourse prior to receiving contraception...

Endocrine disruption caused by various anthropogenic compounds is of persisting concern, especially for aquatic wildlife, because surface waters are the main sink of these so-called endocrine disruptors (ED). In the past, research focused on (anti)estrogenic, (anti)androgenic, and (anti)thyroidal substances, affecting primarily reproduction and development in vertebrates; however, other endocrine systems might be also targeted by ED. Environmental gestagens, including natural progestogens (e.g. progesterone (P4)) and synthetic progestins used for contraception, are supposed to affect vertebrate reproduction via progesterone receptors...

Endometriosis is a common cause of pelvic pain and affects up to 10% of women of reproductive age. Aberrant progesterone signaling in the endometrium plays a significant role in impaired decidualization and establishment of ectopic endometrial implants. Eutopic endometrial cells from women with endometriosis fail to downregulate genes needed for decidualization, such as those involved in cell cycle regulation, leading to unbridled proliferation. Several causes of progesterone resistance in the endometrium have been postulated, including congenital "preconditioning", whereby the in utero environment renders infants susceptible to neonatal uterine bleeding and endometriosis...

We extracted 581 thromboembolic events associated with combined oral contraceptives (COC) that occurred between 2004 and 2013 in Japan, from the Pharmaceuticals and Medical Devices Agency database. The most common thromboembolic events associated with COC were deep vein thrombosis, pulmonary embolism and their combination. The reported thromboembolic events increased year by year, in association with an increase in the quantity of prescribed low-dose estrogen progestin after approval for health insurance coverage for dysmenorrhea in 2008 in Japan...

Hormonal regulation of the expression of Mmp15, a proteolytic enzyme indispensable for ovulation in the teleost medaka, was investigated. In an in vitro culture system using preovulatory follicles, Mmp15 expression and ovulation were induced in the presence of recombinant luteinizing hormone (rLh). Both rLh-induced Mmp15 expression and ovulation were 17α, 20β-dihydroxy-4-pregnen-3-one-dependent, suggesting the involvement of a nuclear progestin receptor (Pgr). In vitro follicle ovulation and Mmp15 expression were reduced by treatment with the Pgr antagonist RU-486...

BACKGROUND: Estrogen and progesterone are potent breast mitogens. In addition to steroid hormones, multiple signaling pathways input to estrogen receptor (ER) and progesterone receptor (PR) actions via posttranslational events. Protein kinases commonly activated in breast cancers phosphorylate steroid hormone receptors (SRs) and profoundly impact their activities. METHODS: To better understand the role of modified PRs in breast cancer, we measured total and phospho-Ser294 PRs in 209 human breast tumors represented on 2754 individual tissue spots within a tissue microarray and assayed the regulation of this site in human tumor explants cultured ex vivo...

Endometriosis is an inflammatory disease and nuclear receptors play a crucial role in mediating the inflammatory response. In endometrial stromal cells (ESC), nuclear receptors expression can be influenced by the local environment. Progestins are first-line, on-label treatments of endometriosis that may have direct effects on endometriotic lesions through these nuclear receptors. Therefore, we investigated whether there was an association between nuclear receptors expression and the influence of progestins on inflammatory cytokines production in a preliminary, in vitro study with primary cultures...

Endometriosis is one of the most common benign gynecological diseases affecting 5-10% of women of fertile age, and the condition has received much attention. In spite of this, there are still challenges concerning diagnosing and treatment. The diagnostic delay can be more than ten years, and is especially long concerning teenagers. The symptoms can start already in adolescence, but this knowledge has not fully reached out to the medical profession, for example to general practitioners and pediatricians. As no hormonal treatment has proved to be superior, the least complicated drugs such as combined oral contraceptives or progestins should be the first choice for control of pain...

Progestin is commonly used for young patients suffering from endometrial hyperplasia or cancer. However, there is approximately 30% failure rate with unclear mechanism. We investigated if Nrf2-survivin pathway contributes the progestin resistance (PR) in this setting. Current study detected Nrf2 and survivin protein expression in post progestin treated endometrial tissue samples by using immunohistochemistry. Transfection of Nrf2 and survivin into endometrial cancer cells in vitro was done to determine the roles of Nrf2 and survivin in progestin resistance...

Hormone replacement therapy (HRT) is necessary in adolescents with primary ovarian insufficiency (POI) in order to avoid estrogen deficiency. The goal of this minirewiew is to present the different types of estrogens (17β-estradiol, estradiol valerate, ethinyl estradiol, and combined equine estrogens) as well as the different types of progestins available. In order to choose among the different types of HRTs, the features of each regimen are being discussed as well as their risks and their respective benefits...

Background: Compelling evidence shows that progestins regulate breast cancer growth. Using preclinical models, we demonstrated that antiprogestins are inhibitory when the level of progesterone receptor isoform A (PR-A) is higher than that of isoform B (PR-B) and that they might stimulate growth when PR-B is predominant. The aims of this study were to investigate ex vivo responses to mifepristone (MFP) in breast carcinomas with different PR isoform ratios and to examine their clinical and molecular characteristics...

Background: Estrogen plus progestin therapy increases both mammographic density and breast cancer incidence. Whether mammographic density change associated with estrogen plus progestin initiation predicts breast cancer risk is unknown. Methods: We conducted an ancillary nested case-control study within the Women's Health Initiative trial that randomly assigned postmenopausal women to daily conjugated equine estrogen 0.625 mg plus medroxyprogesterone acetate 2...

OBJECTIVE: To report the reasons for discontinuation of contraceptive methods by women with epilepsy (WWE). METHODS: These retrospective data come from a web-based survey regarding the contraceptive practices of 1,144 WWE in the community, ages 18-47 years. We determined the frequencies of contraceptive discontinuations and the reasons for discontinuation. We compared risk ratios for rates of discontinuation among contraceptive methods and categories. We used chi-square analysis to test the independence of discontinuation reasons among the various contraceptive methods and categories and when stratified by antiepileptic drug (AED) categories...

BACKGROUND: Reports showed that estrogen-progestin oral contraceptive (COC) or tobacco smoking causes increased risk of cardiovascular diseases (CVD) in premenopausal women. Studies also suggest that nicotine; a major tobacco alkaloid may worsen or improve atherothrombotic CVD. Altered hemorheology, prothrombotic and pro-inflammatory biomarkers, have been implicated in the development of atherothrombotic CVD events. However, the effect of non-smoking nicotine exposure on these biomarkers during COC treatment is not yet established...
