Combined estrogen-progestin preparations (CEPs) are associated with thromboembolic (TE) side effects. The aim of this study was to evaluate the incidence of TE using the Japanese Adverse Drug Event Report (JADER) database. Adverse events recorded from April 2004 to November 2014 in the JADER database were obtained from the Pharmaceuticals and Medical Devices Agency (PMDA) website (www.pmda.go.jp). We calculated the reporting odds ratios (RORs) of suspected CEPs, analyzed the time-to-onset profile, and assessed the hazard type using Weibull shape parameter (WSP)...

Emergency contraceptive pills (ECPs) are medications used after unprotected intercourse, underprotected intercourse, or sexual assault to decrease the risk of pregnancy. Availability of ECPs in Hawai'i's retail pharmacies was last assessed in 2007, following over-the-counter access to levonorgestrel ECPs (LNG-ECP) for women age 18 years or older and prior to U.S. Food and Drug Administration (FDA) approval of prescription-only ulipristal acetate (UPA). We conducted a county-by-county subanalysis from a larger observational population-based study on statewide availability of ECPs in Hawai'i's pharmacies...

PURPOSE: Polycystic ovary syndrome (PCOS) is an increasingly prevalent disorder in adolescent girls, commonly presenting with hirsutism/oligomenorrhea, commonly treated with an oral contraceptive (OC), and commonly followed by oligoanovulatory subfertility. We tested whether an intervention targeting the reduction of hepato-visceral adiposity is followed by a higher ovulation rate than OC treatment. METHODS: This randomized, open-label, single-center, pilot proof-of-concept study (12 months on treatment, then 12 months off) was performed in adolescent girls with hirsutism and oligomenorrhea (PCOS by National Institutes of Health; no sexual activity; N = 36; mean age 16 years, body mass index 23...

The pharmacodynamic effects of various combined oral estrogen-progestin combinations (COC) are examined for their components alone or in the various combined formulations. Special emphasis is given to products containing natural estrogens. Areas covered: Recent information on the effect of androgens, estrogens, progestins, as well as various COC combinations on the coagulation cascade will be reviewed aiming at providing an updated picture. The present article reviews hemostatic changes occurring during use of classic and modern combinations of estrogens (ethinyl estradiol, estradiol, estradiol valerate and estetrol) and new progestins (desogestrel, gestodene, dienogest, drospirenone, nomegestrol acetate), compared to classic compounds, such as levonorgestrel...

Progestins used in endocrine therapies bind to multiple steroid receptors and are associated with several side-effects. It is thus important to understand the relationship between steroid receptor cross-reactivity and the side-effect profile of progestins. In cell lines that express negligible levels of steroid receptors, we report for the first time the binding affinities, potencies and efficacies of selected progestins from different generations determined in parallel. We show that the progestins bind to the androgen receptor (AR) with similar affinities to each other and progesterone, while none bind estrogen receptor (ER)-β, and only norethisterone acetate, levonorgestrel and gestodene bind ERα...

Globally, endometrial cancer is the sixth leading cause of female cancer-related deaths. Non-atypical endometrial hyperplasia (EH), has a lifetime progression rate to endometrial cancer ranging from less than 5%, if simple without atypia, to 40%, if complex with atypia. Site specific, long-acting intrauterine devices (IUDs) provide fertility sparing, progestin-based EH medical management. It is unclear which IUD is most beneficial, or if progesterone sensitizing metformin offers improved outcomes. For resolution, PubMed searches for "Mirena" or "Metformin," "treatment," "endometrial hyperplasia," or "stage 1 endometrial cancer," were performed, yielding 33 articles...

The presence of a mixture of progestogens at ng/L concentration levels in surface waters is a worldwide problem. Only a few studies explore the effect of progestogen treatment in a mixture as opposed to individual chemicals to shed light on how non-target species respond to these contaminants. In the present study, we used an invertebrate model species, Lymnaea stagnalis, exposed to a mixture of four progestogens (progesterone, levonorgestrel, drospirenone, and gestodene) in 10ng/L concentration for 3 weeks...

Globally, intrauterine devices (IUDs) are the second most commonly used form of reversible contraception because of their high efficacy, safety, convenience and cost effectiveness. The levonorgestrel releasing intrauterine system with daily average release of 20 mcg (LNG-IUS 20) is the popular choice because of its favorable bleeding patterns and many noncontraceptive benefits. A three year (LNG-IUS 8) became available three years ago. More recently, the LNG-IUS 12 was added. This new IUD shares a smaller frame, narrow inserter and lower rate of amenorrhea with the LNG-IUS 8, but it offers the five years of contraceptive protection of the LNG-IUS 20...

According to international guidelines, women with obesity without other comorbidities can safely use any hormonal contraceptive (HC). However, limited information is available about contraceptive safety for women with obesity since obesity is an exclusion criterion of most contraceptive clinical trials. As such little is known about the possible risks of HC exposure for women with obesity without comorbidities. One way to assess possible long-term risks in this population, even prior to the development of any clinical disease, is to measure alterations in subclinical atherosclerosis markers...

The synthetic progestin levonorgestrel (LNG) is commonly utilized as a component of human oral contraceptives. LNG enters the environment as a component of wastewater treatment plant effluent, and has been measured at low ng/L concentrations in surface waters. LNG has been shown to activate fish androgen receptors, causing the physical masculinization of females, changes in reproductive behavior, and decreases in fecundity. In this present study, the effects of LNG exposure on early stage oogenesis in the fathead minnow (Pimephales promelas) was examined...

Jaydess/Skyla and Kyleena are 'low dose' levonorgestrel releasing intrauterine systems(LNG-IUS). They differ from Mirena and other similar LNG-IUSs in terms of pharmacological properties and physical dimensions. There are currently no defined guidelines to decide when to use Jaydess or Kyleena or Mirena. Areas covered: MEDLINE, POPLINE, PubMed and clinicaltrials.gov were searched using the terms 'Jaydess', 'Skyla', LNG-IUS 13.5mg and 'Kyleena' LNG-IUS 19.5mg. Only clinical research articles as opposed to generalised reviews and opinion papers on the newer LNG-IUSs were considered for review...

INTRODUCTION: Unprotected intercourse after oral emergency contraception (EC) significantly increases pregnancy risk. This underlies the importance of promptly starting effective, ongoing contraception - known as 'quick starting'. However, theoretical concern exists that quick starting might interact with EC or hormonal contraception (HC) potentially causing adverse side effects. METHOD: A systematic review was conducted, evaluating quick starting HC after oral EC [levonorgestrel 1...
