Abstract
PURPOSE To correlate the sexual desire levels with sexual hormone binding globulin and free androgen index in women taking different types of hormonal contraceptives (HCs) containing ethinylestradiol (EE), oestradiol valerate (E2V), 17β-oestradiol (E2), or estetrol (E4), combined or in phasic formulation with different progestogens having antiandrogenic properties. METHODS Three hundred and sixty-seven women (age range 18-46) participated in the study. SHBG and total testosterone (TT) were measured, and the Free Androgen Index (FAI) was calculated. The Female Sexual Function Index (FSFI) and the Female Sexual Distress Scale (FSDS) questionnaires were used to assess sexual function and distress, respectively. RESULTS The highest SHBG values and the lowest FAIs were obtained of women on HCs containing EE than those of women on HCs containing E2V/17β E2 or E4 (p < 0.001). Desire scores and FSFI total scores were lower in women on HCs with EE than in those using HCs containing E2V, 17β E2, or E4 (p ≤ 0.001). The women who were on HCs containing EE reported FSDS levels higher than those containing all the other types of oestrogen. Finally, sexual desire and FSFI total scores had a negative correlation with the SHBG values and a positive correlation with FAI percentage (p ≤ 0.0001). CONCLUSIONS A minority of women using HCs with EE might experience a decreased sexual desire. This was not observed in women on HCs containing E2V, 17 E2, or E4. To avoid HC discontinuation, due to sexual desire reduction, HCs having minor antiandrogenic effects could be taken into consideration.

Abstract
Combined hormone drugs are the basis for orally administered contraception. However, they are associated with severe side effects that are even more impactful for women in developing countries, where resources are limited. The risk of side effects may be reduced by non-hormonal small molecules which specifically target proteins involved in fertilization. In this study, we present a virtual docking experiment directed to discover molecules that target the crucial fertilization interactions of JUNO (oocyte) and IZUMO1 (sperm). We docked 913,000 molecules to two crystal structures of JUNO and ranked them on the basis of energy-related criteria. Of the 32 tested candidates, two molecules (i.e., Z786028994 and Z1290281203) demonstrated fertilization inhibitory effect in both an in vitro fertilization (IVF) assay in mice and an in vitro penetration of human sperm into hamster oocytes. Despite this clear effect on fertilization, these two molecules did not show JUNO–IZUMO1 interaction blocking activity as assessed by AVidity-based EXtracellular Interaction Screening (AVEXIS). Therefore, further research is required to determine the mechanism of action of these two fertilization inhibitors.

Abstract
A new low-dose, once-a-week contraceptive transdermal delivery system (TDS) with 2.3-mg ethinyl estradiol (EE) and 2.6-mg levonorgestrel (LNG; Twirla®) has recently been approved by the US FDA for contraception of women with BMI <30 kg/m2. The rationale for developing this new patch, the preclinical study results and the results from two innovative Phase III clinical trials demonstrate that this patch has an acceptable Pearl index (4.3%) for its indicated users and has safety and tolerability comparable to other similar dose oral combined hormonal contraceptives. This new TDS provides an improvement over the existing TDS products, with significantly lower steady-state estrogen exposure, a level equal to that with 30-µg EE containing oral contraceptives.

Abstract
PURPOSE To examine whether personal history of nausea or history of nausea and vomiting of pregnancy (NVP) in relatives are risk factors for a woman to suffer from NVP. Further, to evaluate if these factors are associated with the severity of NVP. METHODS Cohort study of 2411 pregnant women recruited from maternity health care clinics. The severity of NVP was categorized according to Pregnancy-Unique Quantification of Emesis (PUQE) questionnaire into no/mild/moderate/severe NVP. History of nausea was assessed in connection with motion sickness, seasickness, migraine or other kinds of headache, after anesthesia, related to the use of contraceptives, and other kinds of nausea. History of NVP in relatives was categorized into first-degree (mother/sister) and second-degree relatives (more distant). RESULTS In multivariable analysis including previous personal history of nausea, motion sickness (OR 3.17, 95% CI 1.81-5.56, p < 0.0001) and nausea in migraine (OR 3.18, 95% CI 1.86-5.45, p < 0.0001) were associated with severe NVP. History of nausea in other kinds of headache was associated with moderate NVP (OR 1.91, 95% CI 1.34-2.72, p = 0.001). Women with affected first-degree relatives had higher odds for moderate (OR 3.84, 95% CI 2.72-5.40) and severe (OR 3.19, 95% CI 1.92-5.28) NVP (p < 0.0001). All these results remained significant after adjusting for parity, body mass index, smoking, employment and age. CONCLUSION Women with personal history of nausea or family history of NVP have an increased susceptibility of NVP. This information is useful in pre-pregnancy counselling.

Abstract
The effect of nomegestrol acetate/estradiol (NOMAC/E2) on clitoral and uterine vascularization has never been evaluated. We aimed to investigate, in women consulting for contraceptive needs, the possible changes in clitoral and uterine arteries hemodynamic parameters after 6 months treatment with NOMAC/E2 as compared with other hormonal contraceptives (HCs). In this observational, prospective pilot study, ten women were enrolled. Color Doppler ultrasound was performed on the clitoral and uterine arteries at baseline and after 6 months treatment with NOMAC/E2 (n = 5) or other HCs (n = 5). NOMAC/E2 did not exert any significant effect on clitoral vascular resistance expressed by the pulsatility index (PI); conversely, treatment with other HCs significantly increased this parameter (p = 0.04). The change in clitoral PI between the two groups retained a statistically significant difference even after adjusting for age. In the NOMAC/E2 group, at follow-up, uterine artery PI and acceleration were significantly reduced (p = 0.04), whereas no significant differences were observed in the HCs group; however, the change in uterine artery parameters did not differ significantly between the two groups. NOMAC/E2, differently from other COCs, does not negatively alter the vascular resistance of clitoral arteries and appears as a good contraceptive choice to protect both cardiovascular and sexual health.

Abstract
PURPOSE Menstruation and menstrual symptoms are commonly cited barriers to physical activity in women. The delay or avoidance of menstruation through extended oral-contraceptive (OC) regimens may mitigate these barriers, yet information on menstrual-manipulation practices in young physically active women is sparse. The objective of this study was to investigate prevalence of, and reasons for, menstrual manipulation with OCs in recreationally and competitively active women. METHODS One hundred ninety-one recreationally active (self-reported moderate to vigorous physical activity 150-300 min/wk) women (age 23 ± 5 y), 160 subelite recreationally active (self-reported moderate to vigorous physical activity >300 min/wk) women (age 23 ± 5 y), and 108 competitive (state-, national- or international-level) female athletes (age 23 ± 4 y) completed a self-administered questionnaire assessing OC-regimen habits and reasons for manipulation of menstruation. RESULTS The majority (74%) of OC users reported having deliberately manipulated menstruation at least once during the previous year, with 29% reporting having done so at least 4 times. Prevalence of menstrual manipulation (at least once in the previous year) was not different between competitive athletes, subelite recreationally active women, and recreationally active women (77% vs 74% vs 72%; P > .05). The most cited reasons for manipulating menstruation were special events or holidays (rated by 75% as important/very important), convenience (54%), and sport competition (54%). CONCLUSIONS Menstrual manipulation through extended OC regimens is common practice in recreationally and competitively active young women, for a range of reasons relating to convenience that are not limited to physical activity. This strategy may help reduce hormone-related barriers to exercise participation, thereby positively affecting participation and performance.

Abstract
OBJECTIVES To investigate the effects of a combined oral contraceptive (COC) containing 17β-estradiol (E2) 1.5 mg and nomegestrol acetate 2.5 mg (NOMAC/E2) on the sexual health of women affected by low sexual desire due to COCs containing ethinylestradiol. MATERIALS AND METHODS Eighty-three women (age range 19-32) participated in the study. Sex hormone-binding globulin (SHBG), total testosterone (TT), and free androgen index (FAI) were measured. The Female Sexual Function Index (FSFI) and the Female Sexual Distress Scale (FSDS) questionnaires were used to assess sexual function and distress, respectively. Hormonal levels were measured and questionnaires were administered before the women switched COC NOMAC/E2 usage (baseline) and at the 3-month (first) and 6-month (second) follow-ups. RESULTS SHBG reduction (p < 0.001), TT (p < 0.05), and FAI increases (p < 0.001) were observed during the first and second follow-ups with respect to baseline values. Sexual desire increased from baseline to the first and second follow-ups (p < 0.001). At baseline, the total FSFI score was 22 ± 1.5 and the FSDS score was 16.6 ± 1.3, both indicating sexual dysfunction with sexual distress. At the first follow-up, the total FSFI score and the FSDS score increased toward sexual health values, being 28.3 ± 1.6 and 12.1 ± 1.5, respectively (p < 0.001). At the second follow-up, the FSFI score had risen to 30.6 ± 1.3 (p < 0.001) and the FSDS score had dropped to 8.3 ± 1.4 (p < 0.001). CONCLUSIONS COCs containing E2 are an innovation that could help women to not suffer from low sexual desire during hypoandrogenic COC usage.

Abstract
BACKGROUND In recent years, several new oral contraceptives have become available. In some ways, they represent an evolution in terms of individualization and compliance on the part of women. The new formulations make it increasingly possible to prescribe a specific hormonal contraceptive on an individual basis. METHODS A systematic literature search of PubMed was performed using the following combination of terms: 'oral contraceptives', 'estroprogestins' and 'combined oral contraceptive'. Only English-language papers published between January 2000 and July 2014 were included in our analysis. The present review analyzes all aspects of the choice of oral contraceptives in the different phases of a woman's life in detail. RESULTS Regarding the estrogen component, lowering the dose of ethinylestradiol (EE) helped reduce associated side effects. Natural estradiol is now available and represents a valid alternative to EE. And regarding progestins, the dose has changed over time, as well as the endocrine and metabolic characteristics. These are the fruit of much research into improvement of old products (19-nor-progesterone-derived progestins) with androgenic effects and testing of new molecules with improved metabolic neutrality in terms of insulin sensitivity and lipid parameters. New progestins were a genuine turning point because they greatly reduced major side effects, such as water retention, and their anti-androgenic properties made them indicated for all forms of hyperandrogenism associated with acne and mild hirsutism. The associations of estradiol/dienogest and estradiol/nomegestrol acetate are the most suitable contraceptives for women with abundant menstrual bleeding and can increase the number of potential users of hormonal contraception. CONCLUSION Progress in the provision of new oral contraceptives has improved the risk/benefit ratio, by increasing benefits and reducing risks. The present challenge is to tailor contraceptives to individual needs in terms of efficacy and protection of reproductive health.

Approximately half (51%) of the 6.6 million pregnancies in the US each year are unintended and half of those pregnancies (54%) occur among women not using contraception. Many women discontinue their contraceptives due to method dissatisfaction. Bothersome unscheduled bleeding is one of the main reasons cited by women for stopping a birth control method. Improving counseling and management of these side effects will aide in increasing satisfaction with contraceptive methods. The following review will discuss the bleeding profiles associated with the contraceptive options available in the US. A valuable resource from the Centers for Disease Control and Prevention, the US Selected Practice Recommendations for Contraceptive Use, will be introduced. Definitions of the types of unscheduled bleeding are included, as well as strategies for treatment for each contraceptive method. The evidence whether or not anticipatory counseling increases continuation rates will also be reviewed.

Abstract
The burden of human immunodeficiency virus (HIV) is mainly concentrated to resources-limited countries where the response to available antiretroviral therapy is often limited by the occurrence of toxicity or by the emergence of HIV drug resistance. Efavirenz and nevirapine are the antiretroviral drugs most prescribed in resources-limited countries as part of antiretroviral combination therapy. Their metabolism and conjugation are largely influenced by enzymatic genetic polymorphisms. The genetic variability of their metabolism could be associated to different metabolic phenotypes causing reduced patients' adherence because of toxicity or drug-drug interactions with concomitant therapies. The purpose of this review is to summarize published evidence on pharmacogenetic and pharmacokinetic aspects related to efavirenz and nevirapine, the influence of concomitant anti-tubercular, anti-malarial or contraceptive treatments, and the impact of human genetic variation and drug-drug interaction on the virologic and immunologic response to antiretroviral therapy in resources-limited countries.

Abstract
Identifying women at risk of venous thromboembolism (VTE) is a major public health issue. The objective of this study was to identify environmental and genetic determinants of VTE risk in a large sample of women under combined oral contraceptives (COC). A total of 968 women who had had one event of VTE during COC use were compared to 874 women under COC but with no personal history of VTE. Clinical data were collected and a systematic thrombophilia screening was performed together with ABO blood group assessment. After adjusting for age, family history, and type and duration of COC use, main environmental determinants of VTE were smoking (odds ratio [OR] =1.65, 95% confidence interval [1.30-2.10]) and a body mass index higher than 35 kg.m⁻² (OR=3.46 [1.81-7.03]). In addition, severe inherited thrombophilia (OR=2.13 [1.32-3.51]) and non-O blood groups (OR=1.98 [1.57-2.49]) were strong genetic risk factors for VTE. Family history poorly predicted thrombophilia as its prevalence was similar in patients with or without first degree family history of VTE (29.3% vs 23.9%, p=0.09). In conclusion, this study confirms the influence of smoking and obesity and shows for the first time the impact of ABO blood group on the risk of VTE in women under COC. It also confirms the inaccuracy of the family history of VTE to detect inherited thrombophilia.

Abstract
OBJECTIVES Estetrol (E4) is a natural estrogen produced by the human fetal liver. In combination with drospirenone (DRSP) or levonorgestrel (LNG), E4 blocks ovulation and has less effect on haemostatic biomarkers in comparison with ethinylestradiol (EE) combined with DRSP. This study evaluates the impact of several doses of E4/DRSP and E4/LNG on safety parameters such as liver function, lipid metabolism, bone markers and growth endocrine parameters. METHODS This was a dose-finding, single-centre, controlled study performed in healthy women aged 18 to 35 years with a documented pretreatment ovulatory cycle. Participants received 5 mg or 10 mg E4/3 mg DRSP; 5 mg, 10 mg or 20 mg E4/150 μg LNG; or 20 μg EE/3 mg DRSP as a comparator for three consecutive cycles in a 24/4-day regimen. Changes from baseline to end of treatment in liver parameters, lipid metabolism, bone markers and growth endocrinology were evaluated. RESULTS A total of 109 women were included in the study. Carrier proteins were minimally affected in the E4/DRSP and E4/LNG groups, in comparison with the EE/DRSP group, where a significant increase in sex hormone-binding globulin was observed. Similarly, minor effects on lipoproteins were observed in the E4 groups, and the effects on triglycerides elicited by the E4 groups were significantly lower than those in the EE/DRSP group. No imbalances in bone markers were observed in any groups. No alterations in insulin-like growth factor were observed in the E4 groups. CONCLUSIONS E4-containing combinations have a limited effect on liver function, lipid metabolism, and bone and growth endocrine parameters.

Abstract
OBJECTIVES This study aimed to assess the effect of multivitamin use during the pill-free interval on the continuation rate and side effects of combined oral contraceptives (COCs) within the first few cycles of use. METHODS In this trial, 332 women presenting to public health centres in an Iranian city each received a COC pack containing 21 pills and were randomised to one of three groups: two of the groups also received 42 multivitamin pills or 42 placebo pills to be taken once a day for 7 days before starting COCs and again during the 7-day pill-free interval for five cycles, while the third group received no multivitamin or placebo pills with their COCs. The groups were compared using Cox regression and χ(2) tests. RESULTS There were no losses to follow-up. Continuation rates at the sixth cycle were 88% for the multivitamin group, 75% for the placebo group and 67% for the no intervention group. Compared with the multivitamin group, the six-cycle discontinuation rate was significantly higher in the placebo group (hazard ratio [HR] 2.26, 95% confidence interval [CI] 1.15-4.45; p = 0.019) and no intervention group (HR 3.15, 95% CI 1.66-5.99; p < 0.001). Nausea, mood changes, weight gain and breast tenderness were significantly less common in the multivitamin group than in the other groups in all cycles, and spotting/irregular bleeding and dizziness were significantly less common in most of the second, third and sixth cycle follow-up. CONCLUSIONS Multivitamin supplements could significantly reduce the side effects of COCs in the initial cycles and improve continuation rates. However, the study limitations do not allow for any definite conclusion for their use in clinical practice, especially in communities rich in nutrients.

Abstract
The combined oral contraceptive pill is an effective contraceptive method which can also offer other benefits. However, other contraceptive options should be discussed. If the pill is the chosen method, prescribe a pill with the lowest effective dose of oestrogen and progestogen. Pills containing levonorgestrel or norethisterone in combination with ethinyloestradiol 35 microgram or less are considered first-line. They are effective if taken correctly, have a relatively low risk of venous thromboembolism, and are listed on the Pharmaceutical Benefits Scheme. The pill is usually taken in a monthly cycle. Some women may prefer an extended pill regimen with fewer or no inactive pills.

Abstract
Estroprogestins (EPs) are combinations of estrogen and progestin with several actions on women's health. The different pharmacological composition of EPs is responsible for different clinical effects. One of the most used low-dose EP associations is ethinylestradiol 20 mcg plus levonorgestrel 100 mcg in monophasic regimen (EE20/LNG100). This review summarizes clinical pharmacology, cycle control, and effects on lipid and glucose metabolism, coagulation, body weight/body composition, acne, and sexuality of EE20/LNG100. Overall, EE20/LNG100 combination is safe and well tolerated, and in several studies the incidence of adverse events in the treated group was comparable to that of the placebo group. Cycle control was effective and body weight/body composition did not vary among treated and untreated groups in most studies. The EE20/LNG100 combination shows mild or no effect on lipid and glucose metabolism. Lastly, EE20/LNG100 is associated with a low risk of venous thromboembolism (VTE). In conclusion, in the process of decision making for the individualization of EPs choice, EE20/LNG100 should be considered for its favorable clinical profile.

Abstract
PURPOSE The aim of this study is to evaluate and compare sexual satisfaction with the use of three types of hormonal contraceptives. METHODS We have evaluated the sexological profile of 23 patients, treated with a subdermal hormonal contraceptive containing 68 mg etonogestrel. We have compared this profile to that of other two groups of previously studied patients: one consisting of 26 women treated with a vaginal ring releasing 120 µg/day of etonogestrel and 15 µg/day of ethinylestradiol (EE) and one consisting of 25 women treated with an oral contraceptive containing 20 µg of EE and 150 µg of desogestrel. A further group of 25 women, not in treatment with any type of hormonal contraceptive, has been studied as control group. The Interviewer Rating of Sexual Function (IRSF) has been completed by the patients at the beginning of the study and after cycles of 3 and 6 months of contraceptive usage. RESULTS All three types of hormonal contraceptives have increased positive indicators of patients' sexual life (sexual interest and fantasies, of orgasm number and intensity and satisfaction) and decreased negative ones (anxiousness, discomfort). CONCLUSIONS Subdermal contraception is slower than both intravaginal and oral hormonal contraceptives in giving these effects, but is more effective after a cycle of 6 months of usage.

Abstract
The introduction of the birth control pill as an effective, coitally-independent method of contraception was a public health milestone of the last century. Over time, combined oral contraception (COC) formulations and pill-taking regimens have evolved with improved safety and tolerability while maintaining contraceptive efficacy. In addition to protection against pregnancy, use of combined oral contraception confers a number of significant non-contraceptive benefits to users. COC use is also associated with well-studied risks. Common side effects are generally self-limiting and improve with increasing duration of use while serious adverse events, including venous thromboembolism, are rare among healthy COC users. Contraceptive decision-making should include consideration of both the risks and benefits of a given method versus the real consequences of unintended pregnancy.

Abstract
Combined oral contraceptives (OCs) are the most commonly prescribed medication in women of reproductive age, but despite widespread use, their effect on cognitive performance remains controversial. Given strong evidence for the neurological impact of reproductive hormones, a clear rationale for investigation exists. This systematic review sought to identify, collate and critically appraise studies assessing the impact of OCs on cognition in healthy premenopausal women. Ovid MEDLINE, PsychINFO and EMBASE were comprehensively searched using relevant keywords for original peer-reviewed observational studies or randomised trials published after 1960. Of 1289 references screened, 22 studies were eligible for inclusion. Assembled evidence supports a cognitive impact of OCs restricted to specific domains; however, the quality of evidence is poor. The most consistent finding is improved verbal memory with OC use. Evidence is also emerging that differing progestin androgenicity may lead diverse OC formulations to differentially impact certain cognitive domains, such as visuospatial ability. At present, evidence is inconclusive, contradictory and limited by methodological inconsistencies. There is scope for further research in this area to definitively determine the cognitive impact of OCs.

Abstract
BACKGROUND Concern about estrogen-related adverse effects has led to progressive reductions in the estrogen dose in combination oral contraceptives (COCs). However, reducing the amount of estrogen to improve safety could result in decreased contraceptive effectiveness and unacceptable changes in bleeding patterns. OBJECTIVES To test the hypothesis that COCs containing ≤ 20 μg ethinyl estradiol (EE) perform similarly as those containing > 20 μg in terms of contraceptive effectiveness, bleeding patterns, discontinuation, and side effects. SEARCH METHODS In July 2013, we searched CENTRAL, MEDLINE, and POPLINE, and examined references of potentially eligible trials. We also searched for recent clinical trials using ClinicalTrials.gov and ICTRP. No new trials met the inclusion criteria. Previous searches included EMBASE. For the initial review, we wrote to oral contraceptive manufacturers to identify trials. SELECTION CRITERIA English-language reports of randomized controlled trials were eligible that compare a COC containing ≤ 20 μg EE with a COC containing > 20 μg EE. We excluded studies where the interventions were designed to be administered for less than three consecutive cycles or to be used primarily as treatment for non-contraceptive conditions. Trials had to report on contraceptive effectiveness, bleeding patterns, trial discontinuation due to bleeding-related reasons or other side effects, or side effects to be included in the review. DATA COLLECTION AND ANALYSIS One author evaluated all titles and abstracts from literature searches to determine whether they met the inclusion criteria. Two authors independently extracted data from studies identified for inclusion. We wrote to the researchers when additional information was needed. Data were entered and analyzed with RevMan. MAIN RESULTS No differences were found in contraceptive effectiveness for the 13 COC pairs for which this outcome was reported. Compared to the higher-estrogen pills, several COCs containing 20 μg EE resulted in higher rates of early trial discontinuation (overall and due to adverse events such as irregular bleeding) as well as increased risk of bleeding disturbances (both amenorrhea or infrequent bleeding and irregular, prolonged, frequent bleeding, or breakthrough bleeding or spotting). AUTHORS' CONCLUSIONS While COCs containing 20 μg EE may be theoretically safer, this review did not focus on the rare events required to assess this hypothesis. Data from existing randomized controlled trials are inadequate to detect possible differences in contraceptive effectiveness. Low-dose estrogen COCs resulted in higher rates of bleeding pattern disruptions. However, most trials compared COCs containing different progestin types, and changes in bleeding patterns could be related to progestin type as well as estrogen dose. Higher follow-up rates are essential for meaningful interpretation of results.

Abstract
Taking into account the biological and psychosocial changes during the transition from childhood to adulthood adolescents would need a contraceptive method which ideally would be very effective, independent of compliance, without major health risks during use and no negative impact on the future health of the adolescent, protective against STI, favorable for bone development, with no or only few side effects and having some preventive and therapeutic potential with respect to frequent health problems of adolescent girls. Combined oral contraceptives (COC) used regularly and consistently have a more than 99% efficacy to prevent a pregnancy. COCs have a very low health risk (almost exclusively thromboembolic disease) which seems to differ marginally with respect to dosage and type of the components. Progestogen only oral contraceptives do not have any major negative health impact. The leading side effect is irregular bleeding which in COC users is mainly during the first 3 months and in progestogen only users during the period of use. Other side effects are reported but their frequency is similar to placebo. COC protect against endometrial and ovarian cancer and they may have beneficial effects on a variety of menstrual complaints and acne, which are frequent problems during adolescence. To be effective COCs have to be taken regularly which is frequently not the case. This diminishes considerably their effectiveness depending on the individual compliance. They do not protect against STI and may even have an inhibitory effect on the use of condoms. For most adolescents the risk benefit profile of oral contraceptives is favorable and makes this method valuable. At the same time the prescription of oral contraceptives for adolescents need to be individualized by taking into account the individual risk/benefit profile. Specialized counseling with a high degree of confidentiality adapted to the knowledge and needs of the individual adolescent is desirable.

Abstract
BACKGROUND The pharmacokinetics of the monophasic oral contraceptive nomegestrol acetate (NOMAC) plus 17β-estradiol (E(2)) were investigated after a single dose and multiple dosing. STUDY DESIGN NOMAC/E2 (2.5 mg/1.5 mg) was administered daily to healthy women (18-50 years, n=23) for 24 days; blood samples for pharmacokinetic analysis were obtained on Day 24 and again, after a 10-day pill-free interval, on Day 35 after a single dose. RESULTS NOMAC reached steady state after 5 days with mean ±standard deviation (SD) trough NOMAC concentration (C(av)) of 4.4±1.4 ng/mL. On Day 24, mean±SD peak NOMAC concentration (Cmax, 12.3±3.5 ng/mL) was reached in mean 1.5 h (t(max)); the mean±SD elimination half-life (t(½)) was 45.9±15.3 h. After a single dose, NOMAC mean±SD C(max) was 7.2±2.0 ng/mL and mean±SD t(½) was 41.9±16.2 h. On Day 24, E2 mean±SD C(av) was 50.3±25.7 pg/mL; mean±SD Cmax was 86.0±51.3 pg/mL. After a single dose, mean±SD E2 Cmax was 253±179 pg/mL. CONCLUSIONS These data demonstrate that NOMAC/E2 has a pharmacokinetic profile consistent with once-daily dosing.

Abstract
BACKGROUND Although the use of continuous oral contraceptive pills (OCPs) eliminates scheduled uterine bleeding, unscheduled bleeding is common. The objective of this study was to determine whether progestin dose influences bleeding with use of continuous OCPs. STUDY DESIGN This was a secondary data analysis of two other studies of continuous OCPs. Women were eligible if they were switching from a cyclic hormonal contraceptive to a continuous OCP. Women took a 20-mcg ethinyl estradiol (EE)/100-mcg levonorgestrel (LNG) pill or a 20-mcg EE/90-mcg LNG pill for 112 days. The number of bleeding/spotting days was compared between groups using a t test. Sample size was adequate to detect a difference of 8 days of bleeding/spotting over the 112 day study period (β=0.80, α=0.05). RESULTS Sixty-six subjects were enrolled, 33 in each group. There were no differences in baseline characteristic, missed OCPs or side effects. There were no differences in the mean number of bleeding/spotting days in the first 84 days of the study (90 mcg LNG mean 20.8 (SE 3.6) days versus 100 mcg LNG 17.8 (SE 2.3) days, p=.48), nor was there a difference in the time to amenorrhea (p=.35). CONCLUSION Our results do not support the use of one LNG dose over another to decrease the amount of unscheduled bleeding women experience when initiating a continuous OCP.

Abstract
OBJECTIVES The primary objective was to assess the efficacy, cycle control and tolerability of a monophasic combined oral contraceptive (COC) containing nomegestrol acetate (NOMAC) and 17β-oestradiol (E2). Effects on acne were evaluated as a secondary objective. Results were compared to those of a COC containing drospirenone (DRSP) and ethinylestradiol (EE). METHODS Women (aged 18-50 years) were randomised to receive NOMAC/E2 (2.5 mg/1.5 mg) in a 24/4-day regimen (n=1591) or DRSP/EE (3 mg/30 μg) in a 21/7-day regimen (n=535) for 13 cycles. RESULTS Estimated Pearl Indices for NOMAC/E2 and DRSP/EE were 0.38 and 0.81 in women aged≤35 years and 0.31 and 0.66 for all women (18-50 years), respectively. Scheduled withdrawal bleedings were shorter and lighter among users of NOMAC/E2 and were sometimes absent altogether. Intracyclic bleeding/spotting was infrequent in both groups, and decreased over time. Type and frequency of adverse events were similar to those typically reported for COCs. CONCLUSIONS These data show that NOMAC/E2 provides high contraceptive efficacy with acceptable cycle control as well as an overall adverse event profile similar to that of DRSP/EE.

Abstract
OBJECTIVES To compare the effects of a combined oral contraceptive (COC) containing nomegestrol acetate and 17β-oestradiol (NOMAC/E2) on haemostasis, lipids, carbohydrate metabolism, C-reactive protein (CRP) and sex hormone-binding globulin (SHBG) with those of a COC containing levonorgestrel and ethinylestradiol (LNG/EE). METHODS In a randomised, open-label study, 121 healthy women, 18-50 years of age, were randomly assigned to receive NOMAC/E2 (2.5 mg/1.5 mg) in a 24/4-day regimen (n=60) or LNG/EE (150 μg/30 μg) in a 21/7-day regimen (n=61) for six cycles. The primary outcome was the change from baseline to cycle 6 for all indices. RESULTS All parameters were similar at baseline between the two groups. Over six cycles, NOMAC/E2 had less effect on most haemostatic indices than LNG/EE. Lipids were essentially unchanged with NOMAC/E2, whereas with LNG/EE high-density lipoprotein cholesterol decreased and low-density lipoprotein cholesterol and triglycerides slightly increased. NOMAC/E2 induced negligible changes in glucose and insulin parameters, in contrast to LNG/EE. A much smaller increase in CRP was observed with NOMAC/E2 than with LNG/EE. NOMAC/E2 was associated with a greater increase in SHBG. CONCLUSIONS The monophasic COC NOMAC/E2 had less influence on haemostasis, lipids and carbohydrate metabolism than the COC LNG/EE.

Abstract
BACKGROUND Side effects of oral contraceptive (OC) pills discourage adherence to and continuation of OC regimens. Strategies to decrease adverse effects led to the introduction of the triphasic OC in the 1980s. Whether triphasic OCs have higher accidental pregnancy rates than monophasic pills is unknown. Nor is it known if triphasic pills give better cycle control and fewer side effects than the monophasic pills. OBJECTIVES To compare triphasic OCs with monophasic OCs in terms of efficacy, cycle control, and discontinuation due to side effects. SEARCH METHODS We searched the computerized databases of the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library), MEDLINE, POPLINE, EMBASE, and LILACS, as well as clinical trials databases (ClinicalTrials.gov and the World Health Organization Clinical Trials Registry Platform (ICTRP)) in May 2011. Additionally, we searched the reference lists of relevant articles. We also contacted researchers and pharmaceutical companies to identify other trials not found in our search. SELECTION CRITERIA We included randomized controlled trials (RCTs) comparing any triphasic OC with any monophasic pill used to prevent pregnancy. Interventions had to include at least three treatment cycles. DATA COLLECTION AND ANALYSIS We assessed the studies found in the literature searches for possible inclusion and for their methodological quality. We contacted the authors of all included studies and of possibly randomized trials for supplemental information about the methods used and outcomes studied. We entered the data into RevMan and calculated odds ratios for the outcome measures of efficacy, breakthrough bleeding, spotting, withdrawal bleeding and discontinuation. MAIN RESULTS Of 23 trials included, 19 examined contraceptive effectiveness. The triphasic and monophasic preparations did not differ significantly. Several trials reported favorable bleeding patterns, that is less spotting, breakthrough bleeding or amenorrhea, in triphasic versus monophasic OC users. However, meta-analysis was generally not possible due to differences in measuring and reporting the cycle disturbance data as well as differences in progestogen type and hormone dosages. No significant differences were found in the numbers of women who discontinued due to medical reasons, cycle disturbances, intermenstrual bleeding or adverse events. AUTHORS' CONCLUSIONS The available evidence is insufficient to determine whether triphasic OCs differ from monophasic OCs in effectiveness, bleeding patterns or discontinuation rates. Therefore, we recommend monophasic pills as a first choice for women starting OC use. Large, high-quality RCTs that compare triphasic and monophasic OCs with identical progestogens are needed to determine whether triphasic pills differ from monophasic OCs. Future studies should follow the recommendations of Belsey or Mishell on recording menstrual bleeding patterns and the CONSORT reporting guidelines.

Abstract
BACKGROUND Coadministration of oral contraceptives with protease inhibitors is complicated by drug interactions. An open-label three-period single-sequence study assessed the effect of coadministration of atazanavir (ATV)/ritonavir (RTV) with Ortho Tri-Cyclen(®) and with Ortho Tri-Cyclen(®) LO (Ortho-McNeil-Janssen Pharmaceuticals, Inc., Raritan, NJ, USA) on the pharmacokinetics (PK) of ethinyl estradiol (EE), norgestimate (NGM), ATV and RTV. METHODS A total of 20 healthy women aged 18-45 years received study treatments. In the lead-in period and in period 1, participants received a full cycle of Ortho Tri-Cyclen (EE 35 μg with NGM 0.18/0.215/0.25 mg) from days 1-28. In period 2, participants received a full cycle of Ortho Tri-Cyclen LO (EE 25 μg with NGM 0.18/0.215/0.25 mg) plus ATV/RTV (300/100 mg once daily) on days 29-42. PK assessments were performed on days 14 and 42 in periods 1 and 2, respectively. RESULTS ATV/RTV with dose-normalized EE/NGM resulted in geometric mean reductions of 16% in EE peak plasma concentration (C(max)), 19% in EE area under the concentration-time curve for a dosing interval (AUC([τ])) and 37% in EE lowest plasma concentration (C(min)), compared with EE 35 μg with NGM in the absence of ATV/RTV. NGM with EE and ATV/RTV 300/100 mg once daily resulted in increases of approximately 68%, 85% and 102% in 17-deacetyl NGM C(max), AUC((τ)) and C(min), respectively. Two participants discontinued the study because of adverse events. CONCLUSIONS ATV/RTV with Ortho Tri-Cyclen was well-tolerated and reductions in EE were not predicted to decrease contraceptive efficacy if the formulation contained ≥30 μg of EE.

Abstract
OBJECTIVE To compare the effects on ovarian activity of two oral contraceptives containing nomegestrol acetate (NOMAC)/17 beta-oestradiol (E2) or drospirenone (DRSP)/ethinylestradiol (EE). METHODS In this open-label, randomised, six-cycle study, 32 subjects using NOMAC/E2 (2.5-1.5 mg; 24/4-day regimen) were compared to 16 subjects using DRSP/EE (3 mg-30 microg; 21/7-day regimen). Measurements included serum oestradiol, progesterone, follicle stimulating hormone (FSH) and luteinising hormone (LH), and ultrasonography of follicular diameter. RESULTS No ovulations occurred during treatment. Progesterone was fully suppressed, with mean maximum values <2 nmol/l in both groups over all cycles. For NOMAC/E2, mean maximum follicular diameter decreased from 19.3 mm before treatment to between 6.9 and 8.2 mm during treatment, with no subject having a follicular diameter ≥15 mm. For DRSP/EE, a decrease from 19.6 to between 7.4 and 10.8 mm was observed, with two subjects (12.5%) having a maximum follicle diameter ≥15 mm. These findings were consistent with observed FSH reductions; full suppression of LH surges was observed in both groups. Post-treatment return of ovulation in both groups occurred on average 21 days after the last active tablet intake. CONCLUSIONS NOMAC/E2 achieves consistent ovulation inhibition, with suppressive effects on the ovaries at least similar to those of DRSP/EE.

Abstract
BACKGROUND Concern about estrogen-related adverse effects has led to progressive reductions in the estrogen dose in combination oral contraceptives (COCs). However, reducing the amount of estrogen to improve safety could result in decreased contraceptive effectiveness and unacceptable changes in bleeding patterns. OBJECTIVES To test the hypothesis that COCs containing ≤ 20 μg ethinyl estradiol (EE) perform similarly as those containing > 20 μg in terms of contraceptive effectiveness, bleeding patterns, discontinuation, and side effects. SEARCH STRATEGY We searched CENTRAL, MEDLINE, EMBASE, POPLINE, ClinicalTrials.gov, and ICTRP, and examined references of eligible trials. Initially, we wrote to oral contraceptive manufacturers to identify trials. SELECTION CRITERIA English-language reports of randomized controlled trials were eligible that compare a COC containing ≤ 20 μg EE with a COC containing > 20 μg EE. We excluded studies where the interventions were designed to be administered for less than three consecutive cycles or to be used primarily as treatment for non-contraceptive conditions. Trials had to report on contraceptive effectiveness, bleeding patterns, trial discontinuation due to bleeding-related reasons or other side effects, or side effects to be included in the review. DATA COLLECTION AND ANALYSIS One author evaluated all titles and abstracts from literature searches to determine whether they met the inclusion criteria. Two authors independently extracted data from studies identified for inclusion. We wrote to the researchers when additional information was needed. Data were entered and analyzed with RevMan. MAIN RESULTS No differences were found in contraceptive effectiveness for the 13 COC pairs for which this outcome was reported. Compared to the higher-estrogen pills, several COCs containing 20 μg EE resulted in higher rates of early trial discontinuation (overall and due to adverse events such as irregular bleeding) as well as increased risk of bleeding disturbances (both amenorrhea or infrequent bleeding and irregular, prolonged, frequent bleeding, or breakthrough bleeding or spotting). AUTHORS' CONCLUSIONS While COCs containing 20 μg EE may be theoretically safer, this review did not focus on the rare events required to assess this hypothesis. Data from existing randomized controlled trials are inadequate to detect possible differences in contraceptive effectiveness. Low-dose estrogen COCs resulted in higher rates of bleeding pattern disruptions. However, most trials compared COCs containing different progestin types, and changes in bleeding patterns could be related to progestin type as well as estrogen dose. Higher follow-up rates are essential for meaningful interpretation of results.

Abstract
The past 50 years have seen great advances in combined oral contraceptives (COCs) that have resulted in reduced risks of adverse events and improved cycle control. The most important changes in COCs over time include repeated lowering of the estrogen dose, development of new progestogens, and the reduction or elimination of the pill-free interval. Most recently, formulations that deliver estradiol in lieu of ethinylestradiol have been introduced. The advantages of COCs generally far outweigh the disadvantages. Current options in oral contraception include a wide spectrum of products that enable clinicians to choose the most appropriate formulation for individual women. This article summarises the advances in oral contraceptives over time and describes the most current clinical data regarding the use of COCs.

Abstract
OBJECTIVES The evaluation of birth control issues among orthodox Jews who strictly follow the Halachah (the Jewish codes of conduct). METHODS We examine traditional Jewish concepts and practices of reproduction, review various contraceptive methods, and define problems that may arise with their use in the Jewish orthodox society. We focus on the orthodox and ultra-orthodox (Haredi) elements of the Jewish community. RESULTS The choices of orthodox religious women are limited and determined largely by considerations related to religious doctrine. CONCLUSIONS Understanding the religious, social and cultural background of patients, religious orthodox women in particular, enables to appropriately counsel them.
