Despite the widespread availability of highly effective methods of contraception, unintended pregnancy is common. Unplanned pregnancies have been linked to a range of health, social and economic consequences. Emergency contraception reduces risk of pregnancy after unprotected intercourse, and represents an opportunity to decrease number of unplanned pregnancies and abortions. Emergency contraception pills (ECP) prevent pregnancy by delaying or inhibiting ovulation, without interfering with post fertilization events. If pregnancy has already occurred, ECPs will not be effective, therefore ECPs are not abortificants. Ulipristal acetate (17alpha-acetoxy-11beta-(4N-N,N-dymethilaminophenyl)-19-norpregna--4,9-diene-3,20-dione) is the first drug that was specifically developed and licensed for use as an emergency contraceptive. It is an orally active, synthetic, selective progesterone modulator that acts by binding with high affinity to the human progesterone receptor where it has both antagonist and partial agonist effects. It is a new molecular entity and the first compound in a new pharmacological class defined by the pristal stem. Up on the superior clinical efficacy evidence, UPA has been quickly recognized as the most effective emergency contraceptive pill, and recently recommended as the first prescription choice for all women regardless of the age and timing after intercourse. This article provides literature review of UPA and its role in emergency contraception.

Obesity has a deteriorating impact on women with PCOS, although prevalence and the impact of specific traits of PCOS remain inconstant in different populations. Therefore, the aim of this study was to explore the differences in clinical, hormonal and metabolic features between obese and nonobese Croatian women diagnosed as having PCOS according to Rotterdam consensus criteria. The study included 74 obese and 208 nonobese women with PCOS. Clinical, biochemical and metabolic variables were compared among those PCOS subgroups. Obese subjects with PCOS had a higher risk of developing oligo-amenorrhea (OR 3.7; 95% CI, 1.1-12.5) and lower risk for developing hirsutism and acne (OR 0.2; 95% CI, 0.1-0.3 and OR 0.8; 95% CI 0.5-1.4, respectively). Obese PCOS subjects also had a higher risk of developing hyperandrogenemia (OR 2.5; CI 95% 0.9-6.7), insulin resistance (OR 4.5; CI 95%, 2.6-7.9), hypercholesterolemia (OR 5.0, CI 95% 2.5-10.2), hypertriglyceridemia (OR 5.2; 95% CI, 2.9-9.2) as well as elevated serum CRP levels (OR 4.1; 95% CI 1.4-12.2) compared to nonobese PCOS women. In conclusion, nonobese Croatian women with PCOS are more inclined to cosmetic problems associated with PCOS then metabolic ones. This is the first study to report the impact of obesity on acne and irregular menses as a study outcome. Obesity deteriorates menstrual regularity, insulin sensitivity and lipid profile in Croatian women with PCOS; therefore one of the fundamental treatment strategies of PCOS should be obesity prevention.

The aim of this study was to calculate the relative prevalence of all phenotypes of polycystic ovary syndrome (PCOS) and to compare them for anthropometrical, hormonal and metabolic differences according to the Rotterdam Criteria. A total of 300 women with PCOS aged 26.7 +/- 5.6 years (mean +/- SD) and 100 women aged 28.3 +/- 4.1 years (mean +/- SD) were included in a control group. Anthropometrical, hormonal and metabolic parameters were compared between the groups. The most prevalent phenotype in our population was the most severe, phenotype A (56.7%), followed by phenotype D (26.7%) and phenotype C (14.3%). Phenotype B was present in only 2.3% of patients. The four main phenotypes did not differ in age, BMI and WHR. Women with phenotypes A and C had increased levels of LH and an increased LH/FSH ratio along with elevated androgen levels compared to the other groups. Serum glucose levels did not differ between the groups studied, however, higher levels of insulin, GIR and HOMA-IR were found between phenotype A and the control group. Phenotype C PCOS or ovulatory PCOS have the same characteristics as classic PCOS, however in a more mild form, which represents a transition between the classic form and the control group. Compared to the control group, phenotype D had higher mean levels of serum testosterone (still within normal range) along with elevated LH levels and LH/FSH ratio, similar to classic PCOS. However, compared with women diagnosed with PCOS based on hyperandrogenism, oligo-ovulation and polycystic ovaries, these patients demonstrated milder endocrine and metabolic abnormalities. Therefore, from an endocrine point of view, our study supports the inclusion of a normoandrogenic anovulatory phenotype in PCOS diagnostic criteria.

Polycystic ovary syndrome (PCOS) is a common endocrine condition affecting women of reproductive age. There are many typical signs and symptoms that allow for the diagnosis of PCOS depending on the criteria used. Interestingly, ethnicity influences the extent of these signs and symptoms; therefore, the frequency of symptoms varies between different countries and ethnic groups. The prevalence of this syndrome in Croatia is unknown, and it's clinical and biochemical characteristics have not yet been reported. During this study, we used the Rotterdam criteria to evaluate 365 Croatian women with PCOS, and compared them to 304 age matched controls to assess the clinical and biochemical abnormalities that occur in PCOS patients. The mean age of PCOS patients at presentation was 26.1 +/- 5.9 years and of controls were 28.0 +/- 4.2 years. Women with PCOS has significantly higher body mass index (BMI) than the control group, although in both groups most patients had normal weight (76.2% vs. 87.8%). Abdominal distribution of fat tissue was similar in both groups. Menstrual cycle abnormalities were observed in 90.7% of PCOS patients, and ultrasonographic appearance of polycystic ovaries was reported in 97.3% of PCOS cases. Nearly 75% of patients with PCOS had hirsutism and 49.6% had acne. We recorded significantly higher serum levels of luteinizing hormone (LH), total testosterone (TT), free testosterone (fT) and insulin, while the serum levels of sex hormone binding globuline (SHBG) and follicular stimulating hormone (FSH) were significantly lower than in the control group. Serum glucose values were not significantly different between the groups. In conclusion, chronic anovulation, hirsutism and ultrasound appearance of polycystic ovaries are the dominant features of PCOS in Croatian population. The majority of patients with PCOS had normal body weight. The incidence of insulin resistance in this group of patients is less than the previously described frequency in other populations of patients with PCOS and normal weight.

Polycystic ovary syndrome (PCOS) is an exceedingly complex endocrine, reproductive and metabolic disorder of a diverse and still unclear pathogenesis. PCOS affects approximately 10% of women of reproductive age and is considered one of the most common endocrine and reproductive disturbances in its group (1)(2). The syndrome is clinically characterised by oligo/anovulation and infertility, hirsutism and abdominal obesity (3). However, the absence of clearly defined causative factors and mechanisms has historically made research and collaboration regarding PCOS difficult. Nevertheless, recently, European and American communities have come to a consensus regarding the definition of PCOS. The current requirement for diagnosis of PCOS necessitates that at least two of the following criteria are present: ultrasound evidence of polycystic ovaries, oligo/anovulation and/or biochemical evidence of hyperandrogenism after the exclusion of other conditions which cause the same features (4)(2). In addition to the reproductive abnormalities, most women diagnosed with PCOS are predisposed to obesity and insulin resistance as well as dyslipidemia and hypertension (5). In other words, there is a high incidence of metabolic syndrome in patients with PCOS. This encompasses the development of type 2 diabetes and cardiovascular disease. Clearly it is the high incidence as well as the yet unknown mechanisms linking PCOS to metabolic and vascular abnormalities which make PCOS of high socioeconomic importance. Additionally, the amelioration of these metabolic and vascular abnormalities has been shown to improve hyperandrogenism and fertility and subsequently requires more scientific elucidation (5). Recent studies have focused on the role of obesity, or more specifically the role of various adipocytes in PCOS. It has been shown that adipocytes are secretory cells that produce a number of proteins with hormonal type functions, collectively referred to as adipokines. In this review we see that a number of studies have shown that the secretion of various adipokines is disrupted in PCOS (6)(7) and that it is considered that this disruption of adipokine secretion could be a significant predictor of metabolic and vascular disease in patients with PCOS (8)(5)(9). Current research is aimed at further elucidating this connection because the early detection of these associated diseases would allow preventative treatment and subsequently result in improved clinical outcome, and improved quality of life for patients with PCOS.
