Abstract
An open-label, single-center, noncomparative study was conducted to determine the effects of a monophasic oral contraceptive containing 100 microg levonorgestrel and 20 microg ethinyl estradiol on ovarian activity. The subjects were 26 healthy women 20 to 35 years of age who had normal ovulatory cycles and were not at risk for becoming pregnant. For 3 treatment cycles, they took 1 tablet of active drug daily for 21 days followed by placebo tablets for 7 days. Follicle diameters and serum progesterone and 17beta-estradiol levels were measured before, during, and after treatment. In 2 (2.7%) of 73 cycles, luteinized unruptured follicles were present and in another 2 (2.7%) cycles, ovulation was confirmed by the disappearance of the enlarged follicle. Ovarian activity, as reflected by mean serum progesterone levels, was restored after treatment. The results of this study are in agreement with those of other studies that showed suppression of ovarian activity in women treated with a monophasic oral contraceptive containing 100 microg levonorgestrel and 20 microg ethinyl estradiol. These results indicate that low-dose 100 microg levonorgestrel and 20 microg ethinyl estradiol given for 21 days is effective in suppressing ovarian activity and they confirm the contraceptive efficacy observed in clinical trials (Pearl index of 0.8).

Abstract
OBJECTIVE This study was undertaken to compare the effects of 2 oral contraceptive regimens on menstrual cycle control and laboratory findings. METHODS In a multicenter randomized study 100 microg levonorgestrel with 20 microg ethinyl estradiol (Alesse or Loette) was given to 155 healthy women. A triphasic preparation of 500, 750, and 1000 microg norethindrone with 35 microg ethinyl estradiol (Ortho-Novum 7/7/7 or TriNovum) was given to 167 women for 1 to 4 cycles of treatment. RESULTS Overall, the percentages of normal menstrual cycles and the percentages of cycles with intermenstrual and withdrawal bleeding were similar between the 2 treatment groups. In the levonorgestrel with ethinyl estradiol group, there was a statistically significantly longer latent period and a statistically significantly shorter withdrawal bleeding episode. Adverse events were similar between treatment groups, and none were serious. Most mean changes from baseline laboratory values were comparable between groups, although the mean increase in cholesterol concentration was statistically significantly lower in the levonorgestrel with ethinyl estradiol group. Changes in triglyceride and glucose concentrations were not statistically significantly different between groups. CONCLUSIONS Levonorgestrel (100 microg) with ethinyl estradiol (20 microg) provides menstrual cycle control equivalent to that obtained with triphasic norethindrone with ethinyl estradiol (75% higher estrogen dose) with similar safety and tolerability.

Abstract
OBJECTIVE The aim of this 24-cycle study was to evaluate the effects on serum lipid concentrations of an oral contraceptive preparation containing 100 microg levonorgestrel and 20 microg ethinyl estradiol. STUDY DESIGN Forty-two healthy women were enrolled in a study designed to evaluate the effects on serum lipid concentrations of an oral contraceptive containing 100 microg levonorgestrel and 20 microg ethinyl estradiol. Lipid data were evaluated for 28 women who completed 24 cycles of treatment with a preparation of 100 microg levonorgestrel with 20 microg ethinyl estradiol for 21 days followed by placebo for 7 days. Concentrations of triglycerides, total cholesterol, high-density lipoprotein cholesterol, high-density lipoprotein cholesterol subfractions 2 and 3, low-density lipoprotein cholesterol, and apolipoproteins A-I and B were analyzed. Mean percentage changes from baseline were tested for significance by means of paired Student t tests. RESULTS Total cholesterol, high-density lipoprotein cholesterol, high-density lipoprotein subfraction 2, and apolipoprotein A-I concentrations were not significantly changed from baseline. Neither was the ratio of high-density lipoprotein subfraction 2 to high-density lipoprotein subfraction 3. Mean percentage increases in concentrations of triglyceride, high-density lipoprotein subfraction 3, apolipoprotein B, and low-density lipoprotein cholesterol and increases in the ratios of total cholesterol to high-density lipoprotein cholesterol, low-density lipoprotein cholesterol to high-density lipoprotein cholesterol, and apolipoprotein B to apolipoprotein A-I were significant (P <.05) at >/=1 cycle. By cycle 24, however, only the concentration of high-density lipoprotein subfraction 3 remained significantly elevated. CONCLUSION Changes in the plasma lipid profiles among women receiving monophasic 100 microg levonorgestrel with 20 microg ethinyl estradiol were similar to those seen with other low-dose oral contraceptives, but by cycle 24 only 1 of 7 mean values remained significantly different from baseline.

Abstract
The efficacy and safety of a low-dose 21-day combination oral contraceptive containing 100 microg levonorgestrel and 20 microg ethinyl estradiol were evaluated in an open-label, multicenter trial. A total of 1708 subjects with regular menstrual cycles (27,011 cycles) were evaluated. The oral contraceptive was administered once a day for 21 days, followed by 7 days of placebo for a complete cycle. During 26,554 cycles evaluated for efficacy, 18 pregnancies occurred (Pearl index of 0.88); 6 of these events were attributable to subject noncompliance. After 30 cycles of exposure the cumulative rate of withdrawal as a result of accidental pregnancy was 1.9%. Breakthrough bleeding (with or without spotting) occurred in 12.9% of the cycles and spotting alone occurred in 10.1% of the cycles. The 2 most common adverse events cited as reasons for discontinuation were headache (2% of subjects) and metrorrhagia (2%). One serious event led to withdrawal of a subject. Overall, the results of this study demonstrate that the monophasic regimen of 100 microg levonorgestrel and 20 microg ethinyl estradiol offers effective contraception, acceptable cycle control, and a good tolerability profile.

Abstract
OBJECTIVE This study was undertaken to evaluate the effects on hemostatic factors of a low-dose preparation of levonorgestrel and ethinyl estradiol in a 12-cycle study. STUDY DESIGN Thirty healthy women began taking 100 microg levonorgestrel and 20 microg ethinyl estradiol on the first day of the menstrual cycle, continued to take the preparation for the next 21 days, and then took placebo for 7 days. Mean changes in prothrombin time, partial thromboplastin time, and levels of factors VII and X, antithrombin, plasminogen, fibrinogen, protein S, thrombin-antithrombin complexes, and D-dimer were analyzed at baseline and at cycles 3, 6, and 12 with paired Student t tests. RESULTS Factor X, plasminogen antigen and activity, and D-dimer levels were significantly increased (P </=.01) during all 3 cycle periods. Antithrombin antigen and protein S total antigen levels were significantly (P </=.001 ) decreased at cycles 3, 6, and 12, whereas factor VII and protein S activity levels were significantly (P </=.05) decreased at cycle 3 and at cycles 3 and 6, respectively. CONCLUSION The effects on hemostatic factors in healthy women of a monophasic preparation of 100 microg levonorgestrel and 20 microg ethinyl estradiol were similar to those of other low-dose oral contraceptives.

Abstract
DMPA and implants have played an important role in the attempt to prevent teenage pregnancies. Adolescent health care providers should provide continued counseling to girls using DMPA or implants and should promptly address any concern associated with these methods. Future studies are warranted to explore ways to prevent or reduce the side effects of DMPA and implants, as well as to develop new, optimal, long-acting contraceptives. Detailed baseline information should be obtained in every future study that explores the presence of side effects during the use of long-acting contraceptives.

Abstract
BACKGROUND Endocrine treatment of hyperandrogenism in women with polycystic ovary syndrome (PCOS) aims at reduction of androgens and increasing sex hormone binding globuline (SHBG), which are also side effects of ovarian electrocautery (OE) when used for induction of ovulation. METHODS Hormonal effects of ovarian electrocautery were compared with the effects of oral contraceptives (OC) containing desogestrel (DG) or cyproteron acetate (CPA). OCs were given to 18 women with PCOS as their sole treatment (group A) and to 23 women after the restoration of regular ovulatory cycling by ovarian electrocautery (group B). RESULTS Ovarian electrocautery induced ovulation and increased the concentration of estrogens and especially progesterone, while OC induced the opposite effects. In the androgens and SHBG the two treatments induced changes that were in the same direction, but OC treatment induced changes that exceeded those of OE. The concentration of SHBG increased from 27.9 to 127.7 nmol/L on OC treatment (Group A), compared with 37.2 to 44.9 after OE (Group B). The androgens decreased, for testosterone the decreases were 2.1 and 0.99 nmol/L, respectively, for androsterone 5.36 and 3 nmol/L, for dihydrotestosterone 0.12 and 0.1 nmol/L, and for DHEAS 3.28 and 1.8 umol/L. No further gain was obtained by the combination of the two treatments. CONCLUSIONS Hyperandrogenism in women with PCOS can be effectively treated with OCs containing DG or CPA. In women with concurrent infertility, however, ovarian electrocautery can be recommended. The only indication for the combination of these two treatments is ambivalence with regard to the fertility after ovulation induction by OE. A temporary delay of ovulatory cycling with OC-treatment after OE has no negative impact upon the future fertility.

Abstract
OBJECTIVE To compare the efficacy, side effects and the effect on next menstruation of levonorgestrel(LNG) to low dose mifepristone in emergency contraception. METHODS The study is a randomized double-blind multicenter comparative trial. The clients who have unprotected intercourse within 72 hours were allocated to one of the two study groups. In LNG group, 0.75 mg LNG was taken twice with 12 hours apart. In mifepristone (Mife-) group, single dose of 10 mg mifepristone was taken and a placebo 12 hours after. Follow-up visit was paid on the seventh day of the expected next menstruation to evaluate the contraceptive efficacy and to record side effects and menstruation. Contraceptive efficacy was calculated by Dixon's method. RESULTS The total valid subjects in LNG and Mife- group were 643 and 633, respectively. There were 20 and 9 pregnancies occurred respectively in each group. The failure rate was 3.1% and 1.4%. Contraceptive efficacy rate of preventing pregnancy was 59.2% and 79.7%, the difference was statistically significant (P < 0.05). The incidence of various side effects was less than 10.0% which were mild. There was no statistically difference between the two groups. The percentage of subjects who had their next menstruation before or after their expected menstruation 3 days in LNG group and Mife- group was 77.7% and 78.5% respectively. The menstrual period less than 7 days was 95.0% and 93.3%. CONCLUSION Use of levonorgestrel or low dose mifepristone for emergency contraception is effective and safe.

Abstract
Pregnancy in patients with hypergonadotropic amenorrhea, although previously reported, remains quite rare. Women may conceive spontaneously or following different regimens of ovulation induction, thus indicating that ovarian failure is not always permanent. The case of an 18-year-old woman with premature ovarian failure, who conceived during hormone-replacement therapy, is reported. During hormone-replacement therapy, elevated gonadotropin levels returned to the physiologically normal range. It is suggested that this restored the receptors to luteinizing hormone and to follicle-stimulating hormone, which might have been downregulated. This hypothesis is supported by previous results from clinical trials and experimental work on a rat model.

Abstract
OBJECTIVE Decreases in circulating growth hormone (GH) and its main biological messenger insulin-like growth factor-I (IGF-I) have been interpreted as part of the aging process. Because estrogens participate in modulating GH synthesis and secretion, hypoestrogenism in menopausal women may lead to GH deficiency. The aim of the present study was to determine the effect of hormone replacement therapy (HRT) on both GH and IGF-I levels as well as insulin concentrations in 50 menopausal women. DESIGN Patients were assigned randomly into two treatment groups of 25 each; one group received three cycles of conjugated equine estrogen (CEE) 0.625 mg/day for 21 days, and the other, 1.25 mg/day during 21 days. Each also received chlormadinone acetate for 5 days. There was a control group consisting of regularly menstruating women. RESULTS In the menopausal women, HRT increased significantly (p < 0.001) the low levels of GH and IGF-I; on the contrary the baseline insulin levels declined (p < 0.001) with HRT. A significant linear correlation (r = 0.90) was found between GH and IGF-I as well as with estradiol levels (r = 0.74) in the group of menopausal women receiving CEE 0.625 mg/day. This group of patients had a significant correlation (r = -0.63) between insulin and estradiol levels. No correlation was observed in the group receiving CEE 1.25 mg/day. CONCLUSIONS HRT restored GH, IGF-I, and insulin levels to normal values in all women. Further research needs to be done to establish the beneficial effect of HRT regarding the prevention of the metabolic effects presumably caused by derangement in the somatotropic axis associated with aging.

Abstract
OBJECTIVES Our aim was to assess the effects of a combined oral contraceptive (OC) preparation on bone quantitative ultrasound and biochemical markers of bone metabolism in perimenopausal women. DESIGN Bone biochemical markers and bone quantitative ultrasound were evaluated in a longitudinal 2-year follow-up study conducted in healthy, normally menstruating perimenopausal women, perimenopausal oligomenorrheic women, and age-matched oral contraceptive-treated women (20 micrograms of ethinyl estradiol plus 0.15 mg desogestrel). The results were analyzed by factorial or repeated-measures analysis of variance, as appropriate. RESULTS In normal women, there were no significant modifications in menstrual cycle, plasma FSH and estradiol levels, biochemical markers of bone turnover, and bone quantitative ultrasound. Conversely, in oligomenorrheic women, an increase in the cycle length with a concomitant rise in circulating plasma FSH and parallel decrease of plasma estradiol levels was evident. In this group, an increase in both urinary excretion of hydroxyproline and plasma osteocalcin levels paralleled a decrease in bone quantitative ultrasound. In perimenopausal OC-treated women, the pattern of osteocalcin and urinary excretion of hydroxyproline showed a slight decrease, whereas bone quantitative ultrasound did not show any significant modification. CONCLUSION Perimenopausal OC administration can prevent the increase in bone turnover and the decrease in bone quantitative ultrasound that follow the perimenopausal impairment of ovarian function.

Abstract
Many women remain unaware of classic oral contraceptive (OC) noncontraceptive health benefits even as new health advantages emerge from experience and research. An extensive body of evidence has established that OC protect women against dysmenorrhea and menorrhagia, menstrual cycle irregularities, iron deficiency anemia, ectopic pregnancy, pelvic inflammatory disease, ovarian cysts, benign breast disease, endometrial cancer, and ovarian cancer. In addition, the FDA has stated for the first time that an OC-triphasic norgestimate/35 micrograms ethinyl estradiol--is an effective treatment for moderate acne vulgaris. OC use also appears to prevent osteopenia in hypoestrogenic women. In addition to these noncontraceptive health benefits, OC have proven valuable in the management of a variety of gynecologic disorders, including dysfunctional uterine bleeding, persistent anovulation, premature ovarian failure, functional ovarian cysts, pelvic pain (including secondary dysmenorrhea), mittelschmerz, endometriosis, and the control of bleeding in women with blood dyscrasias. Educating healthcare providers and women about these important noncontraceptive health benefits will result in increased compliance, greater continuation, and fewer unintended pregnancies.

Abstract
Numerous studies have shown that oral contraceptives (OC) provide protection against a wide variety of illnesses and conditions, including loss of bone density, ovarian cysts, menstrual cycle irregularities, dysmenorrhea and menorrhagia, ectopic pregnancy, pelvic inflammatory disease, benign breast disease, endometrial cancer, and ovarian cancer. How OC can be used not only for contraception but also to improve health among women throughout their reproductive years is illustrated by four case presentations: an adolescent with menstrual problems; a 25-year-old mulligravida who wishes to delay childbearing; a 35-year-old who has completed her family and requests tubal ligation; and a 45-year-old with perimenopausal symptoms. In view of their numerous health benefits, OC are to reproductive-age women as hormone replacement therapy is to menopausal women.

Abstract
Myths and misperceptions continue to influence women's opinions about oral contraceptives (OC), despite the immense body of evidence regarding OC safety and efficacy. Patient opinions about OC failure rates and health risks are often far from proven fact, and the health benefits of OC are too often unrecognized. Because successful OC use requires an informed patient, effective communication between clinicians and their patients is needed to correct misinformation, relieve unnecessary fears, and increase OC use. A variety of interactive counseling skills and attitudes can improve the process of patient counseling; they are especially crucial for adolescents, who may be reluctant or unable to easily articulate their concerns. Counseling messages can be geared specifically to the interests and concerns of particular age groups: adolescents, young adults, and perimenopausal women. With thoughtful planning and involvement of all members of the healthcare team, clinicians can create time and opportunities for the provision of consistent, appropriate counseling to all candidates for OC use.

Abstract
OBJECTIVE To determine whether a 5-mg dose of mifepristone is sufficient to prevent pregnancy. DESIGN Clinical study. SETTING Academic research center. SUBJECT(S) Healthy, fertile, sexually active female volunteers. INTERVENTION Volunteers received a 5-mg dose of mifepristone once weekly, starting on cycle day 2, for up to 6 months. This was their only contraceptive method. MAIN OUTCOME MEASURE(S) Number of pregnancies. RESULT(S) The treatment resulted in a significant decrease in pregnancy rate without affecting the menstrual cycle or causing disturbing side effects. CONCLUSION(S) A low dose of mifepristone, which does not inhibit ovulation, reduces fertility significantly by affecting the endometrium. However, the contraceptive effect needs to be improved for the drug to compete with other contraceptive methods.

Abstract
The effect of a triphasic oral contraceptive containing ethinyl estradiol and gestodene (EE/GSD) on various lipid and lipoprotein parameters was compared with that of a monophasic formulation containing 35 micrograms ethinyl estradiol and 250 micrograms norgestimate (EE/NGM). Blood samples were collected from 46 women on days 2, 11, and 21 of the preceding control cycle and of the third, sixth, and twelfth treatment cycles. There was no significant difference between formulations with regard to the influence on any measured parameter. As compared with controls, a significant increase was observed in the plasma levels of total triglycerides (24-78%), total phospholipids (7-20%), very low density lipoprotein (VLDL) triglycerides (61-76%), VLDL-phospholipids (14-60%), low density lipoprotein (LDL) triglycerides (8-35%), LDL-phospholipids (28-30%), high density lipoprotein (HDL) cholesterol (8-16%), HDL 3-cholesterol (11-20%), HDL-triglycerides (17-66%), HDL-phospholipids, HDL 3-phospholipids (7-11%), apolipoprotein (apo) A-I (5-20%) and apo A-II (10-40%) during treatment with both formulations. In contrast, the LDL-cholesterol levels were significantly decreased. These changes in lipid metabolism appear to reflect a predominance of the effect of the estrogen component. The results indicate that both low dose oral contraceptives containing different progestins and different amounts of EE do not exert a deleterious effect on lipoprotein metabolism, as high HDL-cholesterol and low LDL-cholesterol levels are known as low risk factors of cardiovascular disease. In contrast to endogenous hypertriglyceridemia, an EE-induced rise in triglyceride levels does not appear to increase cardiovascular risk if LDL is not increased.

The effect of two triphasic oral contraceptives (Triquilar [TRQ] and Trisiston [TRS]) containing ethinyl estradiol (EE) and levonorgestrel (LNG) on various hormonal parameters was investigated in 26 women during a cross-over study. TRS consisted of 0.03 mg EE + 0.05 mg LNG (six tablets), 0.04 mg EE + 0.075 mg LNG (six tablets), and 0.03 mg EE + 0.15 mg LNG (nine tablets), whereas TRQ was different in the second phase (five tablets) and third phase (10 tablets). Blood samples were taken on days 6, 11, 21, and 28 of the control and washout cycles and the third treatment cycle. Both formulations inhibited ovulation reliably and decreased the serum levels of gonadotropins, free testosterone, and dehydroepiandosterone sulfate in a time-dependent manner, whereas estradiol and testosterone were already suppressed on day 6, indicating a direct suppressive effect on ovarian steroid synthesis. Prolactin, which rose sporadically in some women, was not significantly changed. In contrast, the levels of sex hormone binding globulin, corticosteroid binding globulin, and cortisol were significantly elevated by 100%. During the hormone-free interval of 7 days, all parameters returned at least partly to baseline. There was no significant difference between the effects of both formulations. The results suggest the possibility of a direct inhibitory effect of contraceptive steroids on ovarian steroid synthesis.

Abstract
A 26-year-old woman suffered concomitant inferior vena cava, iliac, and femoral vein thrombosis and cerebral venous thrombosis. Ten days before symptom onset she had started using an oral contraceptive that contained low-dose ethynilestradiol and gestodene. Both protein C deficiency and protein C activated resistance were detected. To our knowledge, the association of cerebral, caval, and ilio-femoral-popliteal venous thrombosis has not been described previously. The severity of the clinical features could be a consequence of the two combined thrombophilic mechanisms and of the continuation of the oral contraceptive. A thrombophilic disorder should be considered in young patients with thromboembolic disease. Because of the high prevalence of the genetic deficiency causing protein C activated resistance, it is probably worthwhile to perform general screening before prescription of oral contraceptives.

Abstract
Contraceptive efficacy, subject acceptability (cycle control, side-effects, acne score and weight gain) and blood pressure of a monophasic oral contraceptive containing 30 microg ethinyl estradiol plus 150 microg desogestrel (Marvelon) were assessed in an open-label 6-cycle multicenter study in Argentina (7 centers) and Venezuela (5 centers). Of the 407 participating women, 389 (95.6%) completed six cycles of treatment, providing data for a total of 2383 cycles. No pregnancies occurred during the course of the study, confirming the high contraceptive reliability of Marvelon. Cycle control was excellent; the duration of withdrawal bleeding decreased during consecutive treatment cycles and the incidence of spotting and breakthrough bleeding was low. The desogestrel/ethinyl estradiol combination was well tolerated and the incidence of minor side-effects, which was already low in the first treatment cycle, in most cases decreased during the subsequent cycles. The preparation was effective in reducing pre-existing acne, whereas it did not induce clinically relevant changes in blood pressure and body weight. Marvelon was shown to provide effective oral contraception, with good tolerance and excellent cycle control in Latin-American women.

Abstract
Although a limited number of drugs make up the mainstay of treatment of endometriosis, many alternative medications have been used in an attempt to improve efficacy. Some have been rigorously evaluated and are of proven benefit, while others show promise in preliminary trials or in animal models. Proper methods of evaluating medical therapy and outcomes are essential. This chapter provides a review of new medical therapies for the treatment of endometriosis and their evaluation.

Abstract
OBJECTIVE To review the literature concerning the mechanism of action and pharmacodynamics of mifepristone (RU486), potential new uses of RU486, and its current use not only as an abortifacient but also as therapy for endometriosis, leiomyoma, breast cancer, and meningioma. DATA IDENTIFICATION AND SELECTION Studies that relate to RU486 were identified through a MEDLINE search. CONCLUSION(S) RU486 is an 11 beta-dimethyl-amino-phenyl derivative of norethindrone with a high affinity for P and glucocorticoid receptors. The receptor binding is not followed by transcription of P-dependent genes. Mifepristone effectively blocks P receptors in the placenta, resulting in the termination of pregnancy. In addition, it has been used in the treatment of leiomyomata, endometriosis, advanced breast cancer, and meningioma. It is a powerful tool to study the molecular action of P and in the future may be used as an estrogen-free contraceptive.

Abstract
Menstrual disorders in adolescents are a common medical problem. For young adolescents, the onset of menses is a time of dramatic physical and psychological change. Providing education to young women regarding the normal process of puberty helps ease some of the anxiety regarding this change. Health professionals can participate in the education of young women by defining the normal process of puberty and menstruation. Menstrual disorders, such as dysmenorrhea, irregularities in menstrual flow, and premenstrual symptoms, can be effectively diagnosed and treated in the adolescent population.
