Abstract
BACKGROUND Many hormonal contraceptives have been associated with changes in carbohydrate metabolism. Alterations may include decreased glucose tolerance and increased insulin resistance, which are risk factors for Type 2 diabetes mellitus and cardiovascular disease. These issues have been raised primarily with contraceptives containing estrogen. OBJECTIVES To evaluate the effect of hormonal contraceptives on carbohydrate metabolism in healthy women and those at risk for diabetes due to overweight. SEARCH METHODS In April 2014, we searched the computerized databases MEDLINE, POPLINE, CENTRAL, and LILACS for studies of hormonal contraceptives and carbohydrate metabolism. We also searched for clinical trials in ClinicalTrials.gov and ICTRP. The initial search also included EMBASE. SELECTION CRITERIA All randomized controlled trials were considered if they examined carbohydrate metabolism in women without diabetes who used hormonal contraceptives for contraception. Comparisons could be a placebo, a non-hormonal contraceptive, or another hormonal contraceptive that differed in drug, dosage, or regimen. Interventions included at least three cycles. Outcomes included glucose and insulin measures. DATA COLLECTION AND ANALYSIS We assessed all titles and abstracts identified during the literature searches. The data were extracted and entered into RevMan. We wrote to researchers for missing data. For continuous variables, the mean difference (MD) was computed with 95% confidence interval (CI) using a fixed-effect model. For dichotomous outcomes, the Peto odds ratio with 95% CI was calculated. MAIN RESULTS We found 31 trials that met the inclusion criteria. No new trials were eligible in 2014. Twenty-one trials compared combined oral contraceptives (COCs); others examined different COC regimens, progestin-only pills, injectables, a vaginal ring, and implants. None included a placebo. Of 34 comparisons, eight had any notable difference between the study groups in an outcome.Twelve trials studied desogestrel-containing COCs, and the few differences from levonorgestrel COCs were inconsistent. A meta-analysis of two studies showed the desogestrel group had a higher mean fasting glucose (MD 0.20; 95% CI 0.00 to 0.41). Where data could not be combined, single studies showed lower mean fasting glucose (MD -0.40; 95% CI -0.72 to -0.08) and higher means for two-hour glucose response (MD 1.08; 95% CI 0.45 to 1.71) and insulin area under the curve (AUC) (MD 20.30; 95% CI 4.24 to 36.36).Three trials examined the etonogestrel vaginal ring and one examined an etonogestrel implant. One trial showed the ring group had lower mean AUC insulin than the levonorgestrel-COC group (MD -204.51; 95% CI -389.64 to -19.38).Of eight trials of norethisterone preparations, five compared COCs and three compared injectables. In a COC trial, a norethisterone group had smaller mean change in glucose two-hour response than a levonorgestrel-COC group (MD -0.30; 95% CI -0.54 to -0.06). In an injectable study, a group using depot medroxyprogesterone acetate had higher means than the group using norethisterone enanthate for fasting glucose (MD 10.05; 95% CI 3.16 to 16.94), glucose two-hour response (MD 17.00; 95% CI 5.67 to 28.33), and fasting insulin (MD 3.40; 95% CI 2.07 to 4.73).Among five recent trials, two examined newer COCs with different estrogen types. One showed the group with nomegestrel acetate plus 17β-estradiol had lower means than the levonorgestrel group for incremental AUC glucose (MD -1.43; 95% CI -2.55 to -0.31) and glycosylated hemoglobin (HbA1c) (MD -0.10; 95% CI -0.18 to -0.02). Two trials compared extended versus conventional (cyclic) regimens. With a dienogest COC, an extended-use group had greater mean change in AUC glucose (MD 82.00; 95% CI 10.72 to 153.28). In a small trial using two levonorgestrel COCs, the lower-dose group showed smaller mean change in fasting glucose (MD -3.00; 95% CI -5.89 to -0.11), but the obese and normal weight women did not differ significantly. AUTHORS' CONCLUSIONS Current evidence suggests no major differences in carbohydrate metabolism between different hormonal contraceptives in women without diabetes. We cannot make strong statements due to having few studies that compared the same types of contraceptives. Many trials had small numbers of participants and some had large losses. Many of the earlier studies had limited reporting of methods.We still know very little about women at risk for metabolic problems due to being overweight. More than half of the trials had weight restrictions as inclusion criteria. Only one small trial stratified the groups by body mass index (obese versus normal).

Abstract
Estrogen and progestins have been used by millions of women as effective combined contraceptives. The safety of hormonal contraceptives has been documented by years of follow-up and serious adverse events that may be related to their use are rare in the young population exposed to these agents. The balance between the benefits and the risks of contraceptive steroids is generally positive in particular when comparing to the risks of pregnancy and especially in women with risk factors. The metabolic changes induced by the synthetic steroids used in contraception, such as lipoprotein changes, insulin response to glucose, and coagulation factors have been considered as potential markers of cardiovascular and venous risk. Observations of these effects have led to modifications of the composition of hormonal contraceptive in order to minimize these changes and hence potentially decrease the risks. The synthetic estrogen Ethinyl-Estradiol (EE) exerts a stronger effect that natural estradiol (E2) on hepatic metabolism including estrogen-dependent markers such as liver proteins. This stronger hepatic impact of EE has been related to its 17α-ethinyl group which prevents the inactivation of the molecule and results in a more pronounced hepatic effect of EE as compared to estradiol. Due to its strong activity, administering EE via a non-oral route does not prevent its impact on liver proteins. In order to circumvent the metabolic changes induced by EE, newer products using more natural compounds such as estradiol (E2) and estradiol valerate (E2V) have been introduced. The synthetic progestins used for contraception are structurally related either to testosterone (T) (estranes and gonanes) or to progesterone (pregnanes and 19-norpregnanes). Several new progestins have been designed to bind more specifically to the progesterone receptor and to minimize side-effects related to androgenic, estrogenic or glucocorticoid receptor interactions. Dienogest (DNG), and drospirenone (DRSP) and the 19-norpregnanes including Nestorone® (NES), nomegestrol acetate (NOMAc) and trimegestone (TMG) have been combined with estrogen either EE or E2 or estradiol valerate (E2V). Risks and benefits of the newer progestins used in contraception depend upon the type of molecular structure, the type and dose of estrogen associated in a combination and the route of administration. The lower metabolic impact of estradiol-based combinations may result in an improved safety profile, but large surveillance studies are warranted to confirm this plausible hypothesis. So far, the contraindications and warnings for use of current COCs also apply to the estradiol-based COCs.

Effects of two low-dose oral contraceptives containing ethinylestradiol and either desogestrel or levonorgestrel on serum lipids and lipoproteins with particular regard to LDL size.

Abstract
This study was designed to determine the effects of two low-dose oral contraceptives, most frequently given in our area, monophasic desogestrel/ethinylestradiol (DG/EE) and triphasic levonorgestrel/ethinylestradiol (LNG/EE), on lipoprotein parameters, especially LDL particle size and HDL subclass distribution (determined by lipid-stained 2%-20% polyacrylamide gradient gel electrophoresis) in 37 healthy normolipidemic women aged 19 to 27 years. Lipid and lipoprotein parameters were measured before the start of treatment and in the third month of oral contraceptive use. Results reflected the estrogen-progestin balance. As compared with baseline values, with both formulations, plasma total cholesterol, phospholipids, and HDL3 cholesterol increased, and LDL-predominant peak size decreased, with a translation of LDL pattern A towards pattern I. With DG/EE, plasma triglycerides, apolipoproteins AI and B increased. With LNG/EE, LDL cholesterol increased, and HDL2 cholesterol decreased. All these modifications were moderate, within threshold limits. Estrogen-dominant monophasic DG/EE appears to be more favorable than progestin-dominant triphasic LNG/EE, since the reduction in LDL-predominant peak size is not associated with an increase in LDL cholesterol or with a decrease in HDL2 cholesterol.

Abstract
The clinical experience with a combined oral contraceptive (COC) containing 150 micrograms desogestrel and 30 micrograms ethinylestradiol is reviewed. Fourteen clinical trials have been reported involving over 44,000 women for more than 190,000 cycles. None of the 17 pregnancies which occurred (overall Pearl Index 0.12) were due to method failure. The incidences of breakthrough bleeding and spotting after 6 treatment cycles varied from 0.1-6.0% and 2.8-11% of subjects, respectively, and at this time they were not significantly different from pretreatment in most trials. About 90% of subjects maintained regular cycles. The incidence of subjective side effects (approximately 5% for headache, 4% for breast tenderness, 2% for nausea) was low. No significant changes occurred in body weight or blood pressure. In all trials, the COC was well accepted and the rates of discontinuation were similar to those in other COC trials. Pharmacodynamic effects have been widely investigated. There were no significant changes in glucose metabolism or in haematological factors except for possibly minor increases in factors VII and X, fibrinogen and plasminogen. Over thirty studies of the effect of the COC on lipid metabolism have been published; significant increases occur in serum triglycerides, HDL-C and apoprotein A1. SHBG concentrations increase 2-3 fold with a consequent decrease in the levels of free testosterone. This effect can be particularly important therapeutically in women with hyperandrogenic skin disorders and 14 trials in women with these disorders have demonstrated significant clinical improvement with the COC. The findings from the various trials show the COC to be effective and acceptable with no adverse metabolic effects.

Abstract
Among the countries in Central and Eastern Europe, Hungary has a high oral contraceptive prevalence rate. Until recently, however, Hungarian women have not had access to combined oral contraceptives with new, third-generation progestogens. Marvelon (30 micrograms ethinylestradiol and 150 micrograms desogestrel) was first introduced in 1981 in Western Europe and has, in a number of different studies, proven an effective and well-tolerated oral contraceptive with no effect on blood pressure and a favorable lipid profile. Marvelon was introduced in Hungary in October 1991. Prior to its introduction, a multicenter study was undertaken in Hungary with Marvelon to confirm the clinical results of studies from other countries. The present study confirmed Marvelon to be an effective, well-tolerated combined oral contraceptive with no relevant effect on blood pressure. Remarkable improvements were noted, especially with regard to side-effects, in switchers from other oral contraceptives. It is concluded that Marvelon is a valuable extension of the range of contraceptive methods available in Hungary.

Abstract
Desogestrel is a gonane progestogen that in early studies had an improved ratio between desired progestational effects and undesired androgenic effects. A review of more than 50 clinical studies suggests that desogestrel differs from progestins currently used in oral contraception in that it does not interfere with the estrogen effects on lipoprotein metabolism. This profile is attributable to the high selectivity of desogestrel.

Abstract
OBJECTIVE We examined the effects of mono and polyphasic oral contraceptives containing desogestrel or levonorgestrel on serum lipoproteins, sex hormone binding globulin and post-heparin plasma lipase activities. DESIGN The women took either desogestrel or levonorgestrel during the first menstrual cycle on days 15-28. They then received monophasic ethinyloestradiol plus either desogestrel or levonorgestrel for three cycles. After this, the women took sequential pills containing ethinyloestradiol plus either desogestrel or levonorgestrel for the three following cycles. Fasting blood samples were drawn pretreatment and at the end of each treatment. PATIENTS The study group consisted of 30 apparently healthy women, aged 18-35. They were randomly divided into desogestrel and levonorgestrel groups, each consisting of 15 women. MEASUREMENTS Cholesterol, triglyceride and phospholipids were determined in whole serum and in all lipoprotein fractions (following isolation of lipoproteins by ultracentrifugation). Plasma apolipoprotein A-I concentration, post-heparin plasma lipase activities and serum sex hormone binding globulin were also measured. RESULTS Desogestrel (150 micrograms/day) did not change serum total triglyceride concentration, whereas levonorgestrel (150 micrograms/day) decreased it. Except for monophasic ethinyloestradiol plus levonorgestrel, the oestrogen-containing combinations increased serum triglyceride level. Low density lipoprotein (LDL) cholesterol remained stable with all treatments, but the cholesterol/triglyceride ratio of LDL decreased during all combinations with ethinyloestradiol. Levonorgestrel reduced total high density lipoprotein (HDL) cholesterol and both progestins reduced HDL2 cholesterol concentration. Addition of ethinyloestradiol reversed this change in the desogestrel but not in the levonorgestrel group. The polyphasic ethinyloestradiol plus levonorgestrel combination did not change total HDL cholesterol. Hepatic lipase was activated with either progestin when administered alone but its activity was suppressed below the baseline level when ethinyloestradiol was added. Conversely, both progestins suppressed sex hormone binding globulin levels, but addition of ethinyloestradiol caused marked increases above baseline. These increases were greater in women taking desogestrel than in those taking levonorgestrel. No treatment affected lipoprotein lipase activity significantly. CONCLUSIONS Monophasic or polyphasic combinations of ethinyloestradiol and desogestrel do not have deleterious effects on serum lipoproteins. If levonorgestrel is used as the progestin component, polyphasic ethinyloestradiol plus levonorgestrel appears more favourable than monophasic ethinyloestradiol plus levonorgestrel.

Abstract
Desogestrel is the most selective progestogen used in oral contraceptives (OCs). The clinical characteristics of the monophasic combined OC containing 150 micrograms desogestrel and 30 micrograms EE per tablet (Marvelon) are in accordance with the strong progestogenic and minimal androgenic effects of desogestrel: a very high contraceptive efficacy is combined with minimal and, in the case of lipid metabolism, even potentially positive effects on metabolic parameters. Through increasing the plasma levels of sex hormone binding globulin, and thereby decreasing the plasma levels of free testosterone, the desogestrel-containing OC also has substantial beneficial effects on acne.

Abstract
Three different oral contraceptive preparations were studied before and after a 3 month treatment period with respect to their effects on plasma lipoprotein parameters. A total of 58 healthy women requesting oral contraception were randomly assigned to three groups. Each woman received either monophasic preparations containing ethinylestradiol and desogestrel (M-DG); ethinylestradiol and gestodene (M-GD); or a triphasic preparation of ethinylestradiol and levonorgestrel (T-LN). As has been reported in other studies, the concentrations of total plasma cholesterol and apolipoproteins B and A-IV did not change significantly in any group. HDL cholesterol, triglycerides, apolipoproteins A-I and A-II increased or tended to increase. Despite the effects of the three hormone preparations on these lipoprotein parameters, however, each led to a highly significant decrease in apolipoprotein E plasma levels. Considering the recently reported observations that oral contraceptives increase the hepatic uptake of cholesterol-rich remnants, this decrease in apo-E plasma levels may in women that take oral contraceptives be directly correlated with increased hepatic lipoprotein metabolism.

Abstract
The effect of sex steroids on lipid metabolism depends on the type and dose of the compounds, the route of administration, and the duration of treatment. Therefore the composition of an oral contraceptive determines the resultant effect on lipids and lipoproteins. During 12 months of treatment, the effects of two oral contraceptives containing 30 micrograms of ethinyl estradiol and 150 micrograms of desogestrel (EE/DG) or 75 micrograms of gestodene (EE/GSD) on 19 serum parameters of lipid metabolism were followed in 11 women each. There was no change in total cholesterol and phospholipids. Total triglyceride levels were significantly elevated only by EE/GSD. After 3 and 6 months of intake of both preparations, a transitory increase in the triglyceride content of very low-density lipoprotein and low-density lipoprotein and a decrease in low-density lipoprotein-phospholipids was observed. After 12 months, very low-density lipoprotein cholesterol, very low-density lipoprotein phospholipids, and apolipoprotein B were significantly elevated, whereas very low-density lipoprotein triglycerides and all components of low-density lipoprotein were unchanged. Most of the components of high-density lipoprotein (HDL) were increased as a result of a rise in HDL3 and apolipoprotein A2, whereas HDL2 and apolipoprotein A1 were not altered. There was no significant difference between the effects of the two preparations, although those of EE/GSD were mostly more pronounced. The increase in high-density lipoprotein, very low-density lipoprotein, and total triglycerides reflects a slight preponderance of the effect of the estrogen component. Because low-density lipoprotein cholesterol and total cholesterol were not changed, treatment with both formulations is in all probability not associated with an elevated risk of atherosclerosis.

Abstract
The effect of two oral contraceptives containing 30 micrograms ethinylestradiol + 75 micrograms gestodene (EE/GSD) or 30 micrograms ethinylestradiol + 150 micrograms desogestrel (EE/DG) upon serum lipids and lipoproteins were measured in 11 women each on days 1, 10, and 21 of the first, third, sixth, and twelfth treatment cycle and compared to the levels on days 1, 10, and 21 of the preceding control cycle. There was no change in total cholesterol (CH) and phospholipids (PL), while total triglycerides (TG) were significantly elevated only during treatment with EE/GSD. After 3 and 6 months of intake of both oral contraceptives, a transitory increase in the TG content of very low-density lipoprotein (VLDL) and low-density lipoprotein (LDL), and a decrease in LDL-PL was observed. After 12 months, VLDL-CH, VLDL-PL, and apolipoprotein B were significantly elevated, while VLDL-TG and all components of LDL were unchanged. Most of the components of high-density lipoprotein (HDL) were increased due to a rise in HDL3 and apolipoprotein A-II, while HDL2 and apolipoprotein A-I were not altered. There was no significant difference between the effects of the two preparations, although those of EE/GSD were mostly more pronounced. The time-dependent change in the effects of the oral contraceptives on various parameters of lipid metabolism demonstrates that the relevance of results of short-time studies may be questionable. There was also a significant alteration in some parameters between day 1 and 10 of the treatment cycles and a tendency to return to the pretreatment levels during the pill-free week, e.g., in total TG and in the PL component of VLDL, LDL and HDL. The increase in HDL, VLDL, and total TG reflects a slight preponderance of the effect of ethinylestradiol on lipid metabolism. The unchanged total CH and LDL-CH and the elevated HDL levels indicate that the risk of the development of atherosclerosis is in all probability not increased during treatment with both preparations.

Abstract
The relative binding affinities (RBAs) of four progestational compounds (norethisterone, levonorgestrel, 3-keto-desogestrel and gestodene) for the human progesterone and androgen receptors were measured in MCF-7 cytosol and intact MCF-7 cells. For the binding to the progesterone receptor, both Org 2058 and Org 3236 (or 3-keto-desogestrel) were used as labelled ligands. The following ranking (low to high) for the RBA of the nuclear (intact cells) progesterone receptor irrespective of the ligand used is found: norethisterone much less than levonorgestrel less than 3-keto-destogestrel less than gestodene. The difference between the various progestagens is significant with the exception of that between 3-keto-desogestrel and gestodene, when Org 2058 is used as ligand. For the cytosolic progesterone receptor, the same order is found with the exception that similar RBAs are found for gestodene and 3-keto-desogestrel. The four progestagens clearly differ with respect to binding to the androgen receptor using dihydrotestosterone as labelled ligand in intact cells; the ranking (low to high) is: norethisterone less than 3 keto-desogestrel less than levonorgestrel and gestodene. The difference between 3-keto-desogestrel and levonorgestrel or gestodene is significant. The selectivity indices (ratio of the mean RBA for the progesterone receptor to that of androgen receptor) in intact cells are significantly higher for 3-keto-desogestrel and gestodene than for levonorgestrel and norethisterone. From these results we conclude that the introduction of the 18-methyl in norethisterone (levonorgestel) increases both the binding to the progesterone and androgen receptors.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
A longitudinal study was conducted to determine the effect of combined desogestrel-ethinylestradiol treatment on lipid profiles in 28 women with polycystic ovarian disease. Mean patient age was 26.3 years (range, 16 to 36 years). Mean patient weight and height were 59.2 kg and 153.8 cm, respectively. After initial assessment, all patients were treated with a cyclical pill containing 150 micrograms desogestrel and 30 micrograms ethinylestradiol. Clinical, hormonal, and lipid determinations were evaluated after 3 and 6 cycles of treatment. The results revealed that, during the treatment course, serum luteinizing hormone, testosterone (T), free testosterone, and dehydroepiandrosterone sulfate decreased significantly, while serum follicle-stimulating hormone and prolactin levels did not change. Increased levels of total triglyceride, alpha, and prebeta lipoproteins, and decreased levels of beta lipoproteins, were observed. The ratio of low-density lipoprotein cholesterol to high-density lipoprotein cholesterol, although showing no significant change, had a tendency to decrease. This lipoprotein change seems to have a favorable rather than an adverse effect on the patients.

Abstract
The effects of the monophasic oral contraceptive preparation desogestrel plus ethinyloestradiol (EE) and triphasic levonorgestrel plus EE on lipid metabolism were compared. Sixteen young healthy female volunteers received monophasic desogestrel plus EE (21 X 150/30), whereas eighteen women received triphasic levonorgestrel plus EE (6 X 50/30 + 5 X 75/40 + 10 X 125/30) for six consecutive cycles. The lipid composition of the various lipoprotein fractions was estimated after separation in a density gradient by ultracentrifugation. In addition, the apolipoproteins A-I and B were assessed. HDL-cholesterol (precipitation method), HDL-2 cholesterol, HDL-2 phospholipids and the ratio apolipoprotein A-I to apolipoprotein B were significantly higher in the monophasic desogestrel group than in the triphasic levonorgestrel group after three and six treatment cycles. HDL-cholesterol (gradient), HDL-phospholipids (gradient), HDL-3 phospholipids and apolipoprotein A-I were only significantly higher after six treatment cycles. No differences between the groups were observed for the other lipid variables studied including triglycerides and VLDL-triglycerides.

Abstract
The effect of a triphasic combination of ethinyl estradiol and levonorgestrel upon various lipoprotein parameters was compared to that of a preparation that contained ethinyl estradiol and desogestrel on days 6, 11, 21, and 28 of a control cycle, the third cycle of treatment with either ethinyl estradiol/levonorgestrel or ethinyl estradiol/desogestrel (11 volunteers each), the third cycle of a 3-month washout period, and the third treatment cycle after crossover change of the preparations. Significant increases were found in total triglycerides (15% to 20%) and phospholipids (8%) with both preparations, whereas total cholesterol and lipoprotein Lp(a) were not altered. High-density lipoprotein triglycerides (50% to 60%) and high-density lipoprotein-3 cholesterol (10% to 15%) were elevated by both contraceptives, high-density lipoprotein cholesterol and alpha-lipoprotein cholesterol only by ethinyl estradiol/desogestrel (11%), whereas high-density lipoprotein phospholipids, high-density lipoprotein-2 phospholipids, high-density lipoprotein-3 phospholipids, and high-density lipoprotein-2 cholesterol were not influenced. Both ethinyl estradiol/levonorgestrel and ethinyl estradiol/desogestrel increased apolipoproteins A (14%), A-I (20% to 30%), and A-II (25% to 35%) significantly. Very low-density lipoprotein triglycerides were elevated (30%) only by ethinyl estradiol/desogestrel, and low-density lipoprotein phospholipids (20%) by both ethinyl estradiol/levonorgestrel and ethinyl estradiol/desogestrel, whereas the other parameters, very low-density lipoprotein phospholipids, very low-density lipoprotein cholesterol, pre-beta-lipoprotein cholesterol, low-density lipoprotein triglycerides, low-density lipoprotein cholesterol, beta-lipoprotein cholesterol, and apolipoprotein B, were not significantly changed. Provided that the assumption is correct that high low-density lipoprotein cholesterol and apolipoprotein B and low high-density lipoprotein subfractions and apolipoprotein A are associated with an elevated risk of atherosclerosis, the results seem to represent beneficial rather than deleterious side effects of the low-dose oral contraceptives.

Abstract
Evidence for the involvement of changes in lipid metabolism and oral contraceptive use in the development of cardiovascular disease is briefly reviewed with particular reference to the main object of the article, to assess the effect of different oral contraceptive formulations on serum lipid levels. The preferred formulations should contain a low dose of ethynyloestradiol and should not increase serum levels of cholesterol and LDL-C or reduce those of HDL-C. Such formulations appear to be the triphasic one containing ethynyloestradiol and levonorgestrel and the ethynyloestradiol-desogestrel combination, which appears to be unique in that it may actually increase HDL-C. However other determinants in addition to effects on lipid metabolism will be important in deciding the choice of an oral contraceptive. Any changes which do occur in serum lipid concentrations with OC use appear within the first three months and do not appear to be progressive with continued use after this time.
