Abstract
We assessed the available evidence regarding adverse effects on surrogate and patient-important health outcomes of third- and fourth-generation combined oral contraceptives among premenopausal women. We performed a systematic review and meta-analysis including randomized controlled trials and observational studies comparing third- and fourth-generation combined oral contraceptives with other generation contraceptives or placebo. Studies that enrolled women aged 15 to 50 years, with at least three cycles of intervention and 6 months of follow-up were included. A total of 33 studies comprising 629,783 women were included. Low-density lipoprotein cholesterol levels were significantly lower in fourth-generation oral contraceptives (mean differences (MD): -0.24 mmol/L; [95% CI -0.39 to -0.08]), while total cholesterol was significantly increased in levonorgestrel users when compared to third-generation oral contraceptives (MD: 0.27 mmol/L; [95% CI 0.04 to 0.50]). A decreased arterial thrombosis incidence was shown in fourth-generation oral contraceptive users, as compared to levonorgestrel (incidence rate ratio (IRR): 0.41; [95% CI 0.19 to 0.86]). No difference was found in the occurrence of deep venous thrombosis between fourth-generation oral contraceptives and levonorgestrel users (IRR: 0.91; [95% CI 0.66 to 1.27]; p = 0.60; I2 = 0%). Regarding the remaining outcomes, data were heterogeneous and showed no clear difference. In premenopausal women, the use of third- and fourth-generation oral contraceptives is associated with an improved lipid profile and lower risk of arterial thrombosis. Data were inconclusive regarding the rest of outcomes assessed. This review was registered in PROSPERO with CRD42020211133.

Abstract
OBJECTIVES To assess the reasons why women chose the combined oral contraceptive (COC) containing ethinylestradiol 30mug and drospirenone 3mg, their perception of it, and their satisfaction with it when used in clinical practice. METHODS This was an uncontrolled survey of women using the ethinylestradiol 30mug/drospirenone 3mg COC in 15 European countries from September to December 2004. The women were invited to participate in this study by their general practitioner, gynecologist, or other family planning provider. The women were asked to complete a four-part questionnaire retrospectively about why they chose the ethinylestradiol 30mug/drospirenone 3mg COC and their experiences with it. RESULTS A total of 10 947 questionnaires were returned and included in the analysis. Of the respondents, 7694 (70%) had switched to the ethinylestradiol 30mug/drospirenone 3mg COC from other oral contraceptives. About two-thirds (6797 [62%]) of respondents stated that they felt better while using the ethinylestradiol 30mug/drospirenone 3mg COC compared with the time before they started using it. The severity of premenstrual symptoms including depressed mood, irritability, breast tenderness or pain, abdominal bloating or swelling, skin and hair problems, and swelling of the extremities all improved during treatment with the ethinylestradiol 30mug/drospirenone 3mg COC. Overall, 10 441 (95%) respondents were satisfied or very satisfied with the ethinylestradiol 30mug/drospirenone 3mg COC and 9016 (82%) would recommend it to a friend. CONCLUSION The additional non-contraceptive benefits of the ethinylestradiol 30mug/drospirenone 3mg COC are important factors that influence patients' perceptions of this oral contraceptive and their satisfaction with its use.

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
In this report, sex/gender research relevant to reproduction on Earth, in conjunction with the extant human and animal observations in space, was used to identify knowledge gaps and prioritize recommendations for future sex- and gender-specific surveillance and monitoring of male and female astronauts. With overall increased durations of contemporary space missions, a deeper understanding of sex/gender effects on reproduction-related responses and adaptations to the space environment is warranted to minimize risks and insure healthy aging of the men and women who travel into space.

Abstract
UNLABELLED BACKGROUND; Combined oral contraceptives (COCs) reduce levels of androgen, especially testosterone (T), by inhibiting ovarian and adrenal androgen synthesis and by increasing levels of sex hormone-binding globulin (SHBG). Although this suppressive effect has been investigated by numerous studies over many years, to our knowledge no systematic review concerning this issue had been performed. This systematic review and meta-analysis was performed to evaluate the effect of COCs on concentrations of total T, free T and SHBG in healthy women and to evaluate differences between the various types of COCs (e.g. estrogen dose, type of progestin) and the assays used to assess total T and free T. METHODS A review of the literature was performed using database searches (MEDLINE, EMBASE and the Cochrane Central Register of Clinical Trials) and all publications (from inception date until July 2012) investigating the effect of COCs on androgen levels in healthy women were considered eligible for selection. Three reviewers were involved in study selection, data extraction and critical appraisal. For the meta-analysis, data on total T, free T and SHBG were extracted and combined using random effects analysis. Additional subgroup analyses were performed to evaluate differences between the various types of COCs (e.g. estrogen dose, type of progestin) and the assays used to assess total T or free T. RESULTS A total of 151 records were identified by systematic review and 42 studies with a total of 1495 healthy young women (age range: 18-40 years) were included in the meta-analysis. All included studies were experimental studies and 21 were non-comparative. Pooling of the results derived from all the included papers showed that total T levels significantly decreased during COC use [mean difference (MD) (95% confidence interval, CI) -0.49 nmol/l (-0.55, -0.42); P < 0.001]. Significantly lower levels of free T were also found [relative change (95% CI) 0.39 (0.35, 0.43); P < 0.001], with a mean decrease of 61%. On the contrary, SHBG concentrations significantly increased during all types of COC use [MD (95% CI) 99.08 nmol/l (86.43, 111.73); P < 0.001]. Subgroup analyses revealed that COCs containing 20-25 µg EE had similar effects on total and free T compared with COCs with 30-35 µg EE. In addition, suppressive effects on T levels were not different when comparing different types of progestins. However, subgroup analyses for the estrogen dose and the progestin type in relation to changes in SHBG levels did show significant differences: COCs containing second generation progestins and/or the lower estrogen doses (20-25 µg EE) were found to have less impact on SHBG concentrations. CONCLUSIONS The current literature review and meta-analysis demonstrates that COCs decrease circulating levels of total T and free T and increase SBHG concentrations. Due to the SHBG increase, free T levels decrease twice as much as total T. The estrogen dose and progestin type of the COC do not influence the decline of total and free T, but both affect SHBG. The clinical implications of suppressed androgen levels during COC use remain to be elucidated.

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
CONTEXT The impact of estrogen plus progestin as an oral contraceptive on high density lipoprotein (HDL) apolipoprotein (apo) AI metabolism in humans is poorly understood. OBJECTIVES This study was designed to measure the in vivo effect of Moneva (30 microg ethinylestradiol, 75 microg gestodene) on HDL apoAI production rate and fractional catabolic rate. DESIGN Using (13)C-leucine, we performed two kinetic studies in the fed state in 10 normolipidemic young women, before and 3 months after beginning Moneva. RESULTS On Moneva, serum triglycerides increased by 12% (P = 0.03) in the fed state, whereas low-density lipoprotein and HDL cholesterol remained unchanged. HDL apoAI pool size and production rate were increased by 9.2% (67.3 +/- 7.1 vs. 61.6 +/- 6.7 mg x kg(-1); P = 0.05) and 26.5% (14.3 +/- 2.7 vs. 11.3 +/- 2.2 mg x kg(-1) x d(-1); P = 0.02), respectively. HDL apoAI fractional catabolic rate was not significantly modified. Three-month treatment by Moneva induced a shift of HDL size distribution from HDL2 toward HDL3 (HDL3 = 51.5 +/- 8.1 vs. 46.5 +/- 9.2% of total HDL; P = 0.02) and an increase in the proportion of apoAI among HDL components (38.8 +/- 4.3 vs. 34.4 +/- 2.8%; P = 0.01). CONCLUSION Oral contraception by estrogen plus progestin induces changes in HDL apoAI metabolism characterized by an increase in production rate and pool size, with a higher proportion of HDL3 particles. Whether or not these changes are beneficial to prevent atherosclerosis has to be explored further.

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 microg ethinyl estradiol (EE) perform similarly as those containing >20 microg in terms of contraceptive effectiveness, bleeding patterns, discontinuation, and side effects. SEARCH STRATEGY We searched computerized databases (CENTRAL, MEDLINE, EMBASE, and POPLINE) up to January 2008, and searched the references of eligible trials. We wrote to oral contraceptive manufacturers to identify eligible trials. SELECTION CRITERIA English-language reports of randomized controlled trials were eligible that compare a COC containing </=20 microg EE with a COC containing >20 microg 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 The primary reviewer evaluated all titles and abstracts located in the literature searches to determine whether they met the inclusion criteria. Two reviewers independently extracted data from the studies identified for inclusion. We wrote to the authors when clarifications or additional data were needed. Data were entered and analyzed with RevMan 4.2. 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 microg 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 microg 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
Sulfonyl chlorides substituted with functional groups having high proton affinity can serve as derivatization reagents to enhance the sensitivity for steroidal estrogens in liquid chromatography electrospray ionization tandem mass spectrometry (LC-ESI-MS/MS). The most commonly used reagent for derivatization of estrogens for LC-ESI-MS/MS is dansyl chloride. In this study, we compared dansyl chloride, 1,2-dimethylimidazole-4-sulfonyl (DMIS) chloride, pyridine-3-sulfonyl (PS) chloride, and 4-(1H-pyrazol-1-yl)benzenesulfonyl (PBS) chloride for derivatization of 17beta-estradiol (E2) prior to LC-ESI-MS/MS. The product ion spectra of the dansyl and DMIS derivatives were dominated by ions representing derivatization reagent moieties. In contrast, the product ion spectrum of the PS derivative of E2 and, to a lesser extent, the PBS derivative, showed analyte-specific fragment ions. Derivatization with PS chloride was therefore chosen for further investigation. The product ion spectrum of the PS derivative of E2 showed intense ions at m/z 272, assigned to the radical E2 cation, and at m/z 350, attributed to the loss of SO(2) from the [M+H](+) ion. Third-stage mass spectrometry of the PS derivative of E2 with isolation and collisional activation of the m/z 272 ion resulted in steroid C and D ring cleavages analogous to those observed in electron ionization mass spectrometry. The product ion spectra of the PS derivatives of estrone, 17alpha-ethinylestradiol, equilin, and equilenin showed similar estrogen-specific ions. Using derivatization with PS chloride, we developed an LC-ESI-MS/MS method with multiple reaction monitoring of primary and confirmatory precursor-to-product ion transitions for the determination of E2 in serum.

Abstract
OBJECTIVE To estimate whether progestin type or estrogen dose influences bleeding patterns, adverse effects, or satisfaction with combined oral contraceptives dosed continuously. METHODS This was a randomized, double blind, 4-arm active treatment study. Subjects received either 100 microg levonorgestrel/20 microg ethinyl estradiol (E2) (20LNG group), 100 microg levonorgestrel/30 microg ethinyl E2 (30LNG group), 1,000 microg norethindrone acetate/20 microg ethinyl E2 (20NETA group), or 1,000 microg norethindrone acetate/30 microg ethinyl E2 (30NETA group) for 180 days. Subjects logged bleeding events and adverse effects on a daily menstrual calendar. An exit survey measured satisfaction with bleeding patterns. RESULTS One hundred thirty-nine women were enrolled. Patients in the 20NETA and 30NETA arms had significantly more days of amenorrhea than the 30LNG arm in the second 90 days (P < .008). The 30LNG group reported more spotting days than the 20NETA group over the entire study period (P < .008) and the 30NETA group for the second 90 days (P < .008). Only a small number of bleeding days were reported with no differences between groups. No differences in adverse effects between groups were found. Women in the 30LNG arm reported lower levels of satisfaction with their bleeding patterns than the other groups (30LNG compared with 20NETA, P = .01; 30LNG compared with 30NETA, P = .001). CONCLUSION The addition of 10 microg of ethinyl E2 to a 20 microg ethinyl E2 pill containing levonorgestrel or norethindrone acetate did not improve bleeding patterns. During continuous dosing, the use of oral contraceptives containing 1,000 microg norethindrone acetate resulted in more days of amenorrhea and fewer days of spotting than preparations containing 100 microg levonorgestrel.

[PMID: 17161118 DOI: 10.1016/j.contraception.2006.08.004] [Citation(s) in RCA: 57] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2006] [Revised: 07/01/2006] [Accepted: 08/02/2006] [Indexed: 11/17/2022]
Abstract
BACKGROUND New low-dose formulations of combination oral contraceptives (COCs) are safe and effective, but they may be associated with an increased risk of breakthrough bleeding. Extending the duration of active hormonal treatment may reduce the frequency of intracyclic bleeding/spotting while maintaining efficacy and tolerability. METHODS This 6-month, open-label, randomized, active-controlled study involved healthy women aged 18-45 years who were at risk for pregnancy. Women were randomized 4:1 to a 24-day regimen of norethindrone acetate 1 mg/ethinyl estradiol 20 micro g (NETA/EE-24) or to a 21-day regimen of the same combination (NETA/EE-21). The outcomes assessed included pregnancy and incidence, duration of bleeding and intensity of bleeding. RESULTS The cumulative risk of pregnancy in the NETA/EE-24 group (n=705) was 0.9% during six cycles of treatment. Compared with NETA/EE-21 (n=181), NETA/EE-24 was associated with significantly fewer intracyclic bleeding days (0.95 vs. 1.63; p=.005), fewer days of withdrawal bleeding (2.66 vs. 3.88; p<.001) and fewer total bleeding/spotting days for Cycles 2-6 (18.6 vs. 23.2; p<.001). NETA/EE-24 was well tolerated, and side effects were generally mild to moderate in severity. CONCLUSIONS NETA/EE-24 is an effective well-tolerated COC that is associated with a bleeding profile more favorable than that of NETA/EE-21.

Abstract
BACKGROUND Side effects of oral contraceptive pills (OCs) 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 STRATEGY We searched the computerized databases of MEDLINE, EMBASE, POPLINE, LILACS and CENTRAL. Additionally, we searched the reference lists of relevant articles and book chapters. We also contacted researchers and pharmaceutical companies in Europe and the U.S. 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 and outcomes studied. We entered the data into RevMan 4.2 and calculated odds ratios for the outcome measures of efficacy, breakthrough bleeding, spotting, withdrawal bleeding and discontinuation. MAIN RESULTS Of 21 trials included, 18 examined contraceptive effectiveness: the triphasic and monophasic preparations did not differ significantly. Several trials reported favorable bleeding patterns, i.e. 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 WHO recommendations on recording menstrual bleeding patterns and the CONSORT reporting guidelines.

Abstract
The Fertility Regulation Group of the Cochrane Collaboration has been assessing the best available evidence on fertility regulation, family size and birth spacing. By the end of 2005, this group had published 32 systematic reviews and 12 protocols; most reviews were on contraception. Because of suboptimal trial quality, firm conclusions could be made in only five reviews. Threats to internal validity in published trials include the absence of description of allocation concealment, intentional exclusion of participants after randomization, failure to use intention-to-treat analyses and lack of treatment blinding. The precision of results has been limited by small sample sizes. The finding that most trials of oral contraceptives were conducted by pharmaceutical companies raises concerns about potential commercial bias. Of necessity, most information about fertility regulation effectiveness and adverse effects comes from observational studies, which vary widely in quality. Systematic reviews of evidence, with an emphasis on randomized controlled trials when available, will continue to improve fertility regulation in the years ahead.

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 also could result in decreased contraceptive effectiveness and unacceptable changes in bleeding patterns. OBJECTIVES To test the hypothesis that COCs containing </=20 mcg ethinyl estradiol (EE) perform similarly as those containing >20 mcg in terms of contraceptive effectiveness, bleeding patterns, discontinuation, and side effects. SEARCH STRATEGY We searched computerized databases (CENTRAL, MEDLINE, EMBASE, and POPLINE) from their inception to November 2003, searched the references of eligible trials, and wrote to oral contraceptive manufacturers to identify eligible trials. SELECTION CRITERIA English-language reports of randomized controlled trials that compare a COC containing </=20 mcg EE with a COC containing >20 mcg EE were eligible. 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 The primary reviewer evaluated all titles and abstracts located in the literature searches to determine whether they met the inclusion criteria. Two reviewers independently extracted data from the studies identified for inclusion. We wrote to the authors when clarifications or additional data were needed. Data were entered and analyzed with RevMan 4.2. MAIN RESULTS No differences were found in contraceptive effectiveness for the 11 COC pairs for which this outcome was reported. Several COCs containing 20 mcg 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/infrequent bleeding and irregular, prolonged, frequent bleeding, or breakthrough bleeding or spotting) than their higher-estrogen comparison pills. AUTHORS' CONCLUSIONS While COCs containing 20 mcg EE may be theoretically safer, this review did not focus on the rare events required to assess this hypothesis. Data from 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.

Abstract
Side effects influence the acceptability and continuation of hormonal contraceptives. Counseling the client about the management of side effects is a principal approach advocated for increasing continuation. Evidence of a biological basis for variation in women's tolerance of hormonal contraceptives argues, however, that greater attention should be given to altering the product rather than principally attempting to alter a woman's ability to deal with the product. Discontinuation rates for hormonal contraceptives, largely attributable to side effects and health concerns, are high in nearly all less-developed countries for which Demographic and Health Survey data are available. Oral contraceptives appear to be particularly problematic for Latin American women, most notably in Bolivia. Clinical trials suggest substantial variation in the physiological response to exogenous hormones, and new evidence confirms the hypothesis that the normal hormonal profiles of Bolivian women are significantly lower than those of women in the United States. These findings suggest a need for more population-specific physiological research linked to analyses of the possible association between endogenous hormone differences and contraceptive continuation. Appropriately adjusting the level of the steroid delivered may benefit women's health and improve the acceptability and continuation of hormonal contraceptives.

Abstract
Twenty-nine women aged 35 years old or more, using triphasic combined oral contraceptive (COC) were evaluated during six cycles for the following parameters: total cholesterol, low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C) and its subfraction HDL2, triglycerides, apoproteins A and B, Castelli risk index I and II (cholesterol/HDL-C and LDL-C/HDL-C) and apoprotein ratio (apoprotein B/apoprotein A). The same laboratory measurements were done in a control group of 49 non-COC-user women. The results showed that there were no differences on most of the studied parameters between user and nonuser women. There was a significant reduction of HDL-C and HDL2-C, although within the normal range. In addition, it was observed a significant increment of triglycerides and apoprotein B at 6 months of follow-up only in user group (p < 0.05), although within the normal range. It is concluded that the use of levonorgestrel triphasic COC appeared to have no additional adverse impact when used by women aged over 35 years. Further studies are needed to obtain conclusive data.

Abstract
Reductions in oral contraceptive (OC) estrogen dose and the development of new progestins have resulted in formulations that maintain acceptable cycle control while improving safety. However, the potential safety benefits of low-estrogen doses may be offset by less acceptable cycle control. These observations have led to the development of 2 triphasic OC formulations containing norgestimate and desogestrel in combination with 25 microg ethinyl estradiol (EE). Both of these 25-microg EE triphasic OCs balance fewer estrogen-related side effects with good cycle control comparable to OCs containing higher estrogen doses. However, questions remain about the risk of venous thromboembolism associated with OCs containing desogestrel. A new monophasic 30-microg EE OC contains drospirenone, a spironolactone analogue with which there is limited experience. Although initial data with this OC are intriguing, product labeling highlights safety issues related to its antimineralocorticoid effects and the potential for hyperkalemia. Further experience with this formulation will determine its role in contraceptive practice.

Abstract
OBJECTIVE To validate an acceptability questionnaire for NuvaRing, a new combined contraceptive vaginal ring. METHODS A 21-item questionnaire was developed covering: ease of ring use, ease of package use, clarity of instructions, sexual comfort, cycle-related characteristics, compliance and satisfaction. A total of 2145 women completed the questionnaire after 3, 6 or 13 cycles of NuvaRing use. The psychometric properties and predictive value of the questionnaire were assessed using cycle 3 data (n = 1950). The quality of completed questionnaires, item content analysis, construct validity, internal consistency reliability, known groups validity and predictive validity were evaluated. RESULTS Excluding non-ordinal items, 0.6% of the data were missing. Principal component analysis of 15 ordinal items indicated that two hypothesised dimensions ('ease of package use' and 'clarity of instructions') were consistently linked and so were combined into a single 'ease of comprehension' scale. Item convergent validity (the degree of correlation between an item and its own scale) was 100% for 'ease of ring use' (r = 0.44) and 'satisfaction' (r = 0.58), 83% for 'ease of comprehension' (r = 0.25-0.62) and 67% (r = 0.38-0.54) for 'sexual comfort', but 0% for 'cycle-related characteristics' (r = 0.31). Item discriminant validity (the degree to which an item correlates with its own scale compared with other scales) was >/=96% for all dimensions. Internal consistency reliability was acceptable for all dimensions (adjusted Cronbach's alpha coefficient >0.70). Satisfaction was higher than in the complementary groups for respondents who had no adverse events, chose NuvaRing as the best method of contraception or completed the study; this indicated good known groups validity. Low satisfaction with the method was a good predictor of early discontinuation after cycle 3, indicating that the questionnaire had good predictive validity. CONCLUSIONS The acceptability questionnaire has good psychometric properties and can predict early discontinuation of the NuvaRing vaginal ring method of contraception.

Abstract
The menopausal transition is a complex period in a woman's life, reflecting ovarian ageing and concomitant hormonal changes, in addition to social and metabolic changes. These changes, in turn, influence the signs and symptoms common to this period. Symptoms which are influenced by the hormonal fluctuations occurring during the menopausal transition include vasomotor symptoms and vaginal dryness; others are breast tenderness, poor sleep and pre-menstrual dysphoria. Hormonal therapy has been shown to be first-line therapy for many of these symptoms. Other types of pharmacotherapies may be helpful, including selective serotonergic uptake inhibitors for vasomotor symptoms. Characteristic signs of the menopausal transition include abnormal uterine bleeding, best managed with hormonal pharmacotherapy; diminishing bone mineral density, which may warrant diagnostic intervention, and may benefit from dietary and lifestyle modifications; and increased body-mass index and worsening lipid profile, which also may benefit from dietary and lifestyle modifications.

Abstract
Norelgestromin (NGMN) and levonorgestrel (LNG) are the main active metabolites of norgestimate (NGM), but their relative contributions to the pharmacological effects of NGM are unclear. We have therefore determined the serum distribution of these NGM metabolites and assessed their steady-state concentrations in women following >or=3 cycles of oral contraceptive (OC) use. The administration of 250 microg NGM/35 microg ethinyl estradiol (EE) resulted in significantly higher sex hormone-binding globulin (SHBG) levels (p = 0.002), and 30% lower serum non-protein-bound (NPB) levels of testosterone, when compared to treatment with 150 microg LNG/30 microg EE. We also confirmed that NGMN does not bind to SHBG, and found that 97.2% of this metabolite is bound to albumin while only 2.8% is in the NPB fraction. In contrast, most of the LNG was bound to SHBG (92.5% and 87.2% after NGM/EE and LNG/EE treatment, respectively), and the NPB fraction of LNG (0.7%) during NGM/EE treatment was lower (p < 0.001) than during LNG/EE treatment (1.4%). Combining these serum distributions with the C(max) and AUC(0-24h) data obtained after NGM/EE treatment gave NPB and albumin-bound values of NGMN that were much greater than the corresponding LNG values. Furthermore, the C(max) and AUC(0-24h) values for NPB LNG during NGM/EE treatment were estimated to be lower than during LNG/EE treatment. Since LNG is primarily bound by SHBG, its access to target tissues is restricted. Moreover, because SHBG does not bind NGMN, it appears to be quantitatively the more important NGM metabolite available to target tissues, and probably accounts for a substantial proportion of the progestogenic activity of NGM/EE OCs. However, it is also possible that simultaneous exposure of NGMN and LNG after treatment with NGM/EE may provide clinical benefits not seen with LNG/EE combinations.

Abstract
Oral contraceptives are one of the most highly effective forms of contraception and provide many short- and long-term noncontraceptive health benefits. They control menstrual cycle irregularities, such as breakthrough bleeding and amenorrhea, and are effective in treating dysfunctional uterine bleeding. In addition, for decades after oral contraceptive use is discontinued they are associated with substantial decreases in the risk of ovarian cancer (up to 80%) and of endometrial cancer (40%-50%), and nearly eliminate benign functional ovarian cysts. Long-term oral contraceptive use confers protection against benign breast disease and colorectal cancer, may help prevent rheumatoid arthritis, decreases ectopic pregnancy and hospitalizations for pelvic inflammatory disease, and helps preserve bone mineral density to reduce risk of fractures. Large bodies of evidence from extensive research have clarified the perceived association of oral contraceptive use with cardiovascular disease and with breast cancer. Findings indicate that there is no increased risk of myocardial infarction or stroke associated with oral contraceptive use in healthy, nonsmoking, normotensive women. Although there is a 3- to 4-fold increased risk of venous thromboembolism with current oral contraceptive use, the absolute risk is very small and is half that associated with pregnancy. Women of all reproductive ages, including perimenopausal women, can realize many health benefits through oral contraceptive use, including improved health status later in life.

Abstract
Perimenopause represents a transition period lasting about 5 years before the permanent cessation of spontaneous menses. During this transition, the emphasis of clinical care changes. Although women still need effective contraception during perimenopause, issues including loss of bone mineral density, menstrual cycle changes, and vasomotor instability also need to be addressed. Hormone replacement therapy is not the first-line treatment for women with symptomatic perimenopause because hormone replacement therapy neither suppresses ovulation nor provides contraception; also, it will not prevent and in fact may aggravate unpredictable perimenopausal bleeding. Oral contraceptives offer many benefits for healthy, nonsmoking, perimenopausal women. Oral contraceptive use by women in their 40s has been found to decrease the risk of postmenopausal hip fractures and regularize menses in women with dysfunctional uterine bleeding, reducing the need for surgical intervention for benign menstrual conditions. Use of oral contraceptives also can reduce long-term risk of endometrial and ovarian cancers. There is also good evidence that oral contraceptives relieve vasomotor symptoms in perimenopausal women. Oral contraceptives can be viewed as a strategy not only to improve perimenopausal symptoms, provide effective contraception, and reduce some long-term health risks, but also to enhance the quality of life for perimenopausal women.

Abstract
Oral contraceptives and combination hormone replacement therapy are underused by most women. Among users, lack of compliance/adherence to oral contraceptive or hormone replacement therapy regimens can lead to discontinuation and deprive women of the full range of benefits achieved through hormone continuity. To prevent unintended pregnancy and to improve the health outcomes of women of all ages and the overall quality of life, adherence and continuation rates need to be improved for oral contraceptive and hormone replacement therapy use. Effective communication and counseling during the oral contraceptive and hormone replacement therapy regimen selection process and subsequent follow-up interactions are essential. Patients need to be informed in a clear and concise manner that, for most women, the benefits of oral contraceptives and hormone replacement therapy outweigh any associated health risks. Data should be presented without epidemiologic jargon and in terms that are easily understood. It is recommended that realistic expectations concerning the possible side effects, especially during the initial use of hormones, are established before use; furthermore, the selection of a formulation should take into account the unique needs of each patient.

Abstract
During the past four decades, oral contraceptives have remained a safe and effective method of birth control. Reductions in the estrogen and progestin dosages have significantly decreased the incidence of cardiovascular complications. The association between oral contraceptives and breast cancer appears to be primarily because of detection bias or possibly a promotional effect. Despite the changes in formulation, the problems related to side effects have not been totally solved. Because compliance and successful use is strongly affected by side effects, improvement in this area is probably the biggest challenge faced by developers of oral contraceptives. It is also clear that there are a growing number of significant noncontraceptive benefits that accrue in oral contraceptive users. Unfortunately, many women do not know about these benefits. Thus, one of the issues that providers need to continue to address is how to provide better information about oral contraceptives and contraception in general to patients.

Abstract
OBJECTIVE To highlight studies that investigated the efficacy, safety, and tolerability of low-dose oral contraceptives (OCs) containing 20 microg of ethinyl estradiol (EE) and to discuss the use of these low-dose contraceptives in women from adolescence to menopause and the noncontraceptive health benefits likely to be afforded by low-dose contraceptives. DESIGN Relevant literature was identified by searching MEDLINE and EMBASE. Other sources were located by consulting the bibliographies of the material collected from Medline and EMBASE. Sources for additional information included documents from the United States Food and Drug Administration and the Physicians' Desk Reference (54th ed.). CONCLUSION(S) The current lowest available dose of EE used for OCs in the United States is 20 microg. Formulations with 20 microg of EE are efficacious and have a low incidence of estrogen-related side effects. Since this lowest effective EE dose inhibits ovarian activity, 20 microg of EE should also provide the noncontraceptive health benefits of OCs. Both contraceptive and noncontraceptive benefits of OCs are available to most women from adolescence to menopause without complications.

Abstract
Persistent and/or unpredictable bleeding is a common reason for discontinuation of hormonal contraceptive methods. An open-label, nonrandomized, parallel, controlled study compared the efficacy, safety, and cycle control of the new, highly efficacious monthly injectable contraceptive containing 25 mg medroxyprogesterone acetate (MPA) and 5 mg estradiol cypionate (E(2)C) (MPA/E(2)C) (Lunelle Monthly Contraceptive Injection) with that of the frequently used norethindrone 0.5, 0.75, 1.0 mg/0.035 mg ethinyl estradiol (NET/EE) triphasic oral contraceptive (Ortho-Novum 7/7/7). This report directly compares the bleeding patterns of women on MPA/E(2)C to those of women on NET/EE and untreated women. Overall, breakthrough bleeding occurred less frequently in women using MPA/E(2)C than in women using NET/EE (p < or =0.01). However, more women using MPA/E(2)C experienced amenorrhea/missed periods than those on NET/EE (p < or =0.01). In addition, the percentage of women experiencing breakthrough bleeding or amenorrhea while using other oral contraceptives is compared to that of women using MPA/E(2)C. A rapidly reversible method, MPA/E(2)C, combines the high contraceptive efficacy of surgical sterilization with the convenience of monthly administration. These data suggest that, for a large proportion of women, MPA/E(2)C offers predictability in bleeding patterns comparable to or greater than that experienced by ovulatory untreated women or those using combination oral contraceptives.

Abstract
The contraceptive efficacy, cycle control, and safety of a new low-dose, triphasic desogestrel/ethinyl estradiol oral contraceptive (CTR 77, Cyclessa(TM)) was compared to that of a marketed, triphasic norethindrone/ethinyl estradiol oral contraceptive (Ortho-Novum(R) 7/7/7). Two identical multicenter, open-label, randomized, parallel group, comparative Phase III 6-cycle trials were designed to each enroll 4200 healthy women. The combined comparative data for Cyclessa versus Ortho-Novum 7/7/7 for both studies are reported here. Cyclessa and Ortho-Novum 7/7/7 had comparable contraceptive efficacy. Despite a lower ethinyl estradiol dose (25 microg/day vs. 35 microg/day), the Cyclessa group had significantly improved cycle control in comparison to the Ortho-Novum 7/7/7 group for presence of a withdrawal bleed (p = 0.001), lack of early withdrawal bleed (p = 0.01), and breakthrough bleeding/spotting (p = 0.001). For each of the months of the study, the incidence of breakthrough bleeding/spotting was lower in the Cyclessa group than the Ortho-Novum 7/7/7 group (breakthrough bleeding, p = 0.006; breakthrough spotting, p = 0.001). The incidence of other adverse events was similar among treatment groups, an observation that supports the safety of both formulations. There was significantly less weight gain (p = 0.0002) and less increase in the body mass index (BMI) (p = 0.0002) in the Cyclessa group. The contraceptive efficacy and safety of Cyclessa is comparable to Ortho-Novum 7/7/7. Cyclessa provides significantly improved cycle control with no weight gain.

Abstract
Estrogen content represents a tradeoff between cycle control and side effects, but few direct comparisons of 20 and 30/35 micrograms preparations are available. To address this issue, we conducted a randomized, open-label multicenter clinical trial comparing Alesse (20 micrograms ethinyl estradiol [EE]), Mircette (20 micrograms EE), and Ortho Tri-Cyclen (35 micrograms EE) among 463 OC starters or switchers. Bloating, breast tenderness, and nausea were approximately 50% more common in women using 35 micrograms EE as compared to 20 micrograms EE preparations. Cycle control was similar in all products, although during the first two cycles among starters; users of Mircette and Ortho Tri-Cyclen (Tri-Cyclen) exhibited better cycle control than Alesse users. Discontinuation and pregnancy rates were not significantly higher in 35 micrograms EE users.
