Abstract
While the use of menopausal hormone therapy [MHT] when initiated in women younger than 60 years is generally considered to have a good safety profile and to be associated with important treatment and prevention benefits, the length of therapy and the long-term risk benefit profile remains highly controversial.

Abstract
Many women, including those with risk factors for cardiovascular disease (CVD), may desire the benefits associated with hormone therapy including protection from progression of CVD, osteoporotic fractures, urogenital atrophy, skin loss, dementia, and a reduction in overall mortality. Before initiating or continuing therapy, it is important to consider an accurate risk benefit analysis in all women. Importantly, when considering initiation of hormone replacement, it is important to consider a woman's age, number of years since her menopause, and a number of cardiovascular risk factors. Women with positive risk factors are at increased risk for hormone therapy, especially related to the initiation of high dose oral therapy. Use of low dose transdermal hormone therapy can reduce these risks. For women with a recent cardiovascular event, current thromboembolic disease, long-standing immobilization, or severe peripheral arterial disease, hormone replacement is generally not recommended. There is growing consensus that the benefit to risk profile for hormone therapy is high for healthy, low-risk women initiating therapy within 10 years of menopause or under age 60. However, special considerations are needed for women who are outside those boundaries or for those that have risk factors for cardiovascular disease.

Abstract
BACKGROUND Although observational studies suggest that estrogen replacement therapy (ERT) reduces cardiovascular morbidity and mortality in postmenopausal women, use of unopposed ERT for prevention of coronary heart disease in healthy postmenopausal women remains untested. OBJECTIVE To determine the effects of unopposed ERT on the progression of subclinical atherosclerosis in healthy postmenopausal women without preexisting cardiovascular disease. DESIGN Randomized, double-blind, placebo-controlled trial. SETTING University-based clinic. PATIENTS 222 postmenopausal women 45 years of age or older without preexisting cardiovascular disease and with low-density lipoprotein cholesterol levels of 3.37 mmol/L or greater (>/=130 mg/dL). INTERVENTION Unopposed micronized 17beta-estradiol (1 mg/d) or placebo. All women received dietary counseling. Women received lipid-lowering medication if their low-density lipoprotein cholesterol level exceeded 4.15 mmol/L (160 mg/dL). MEASUREMENTS The rate of change in intima-media thickness of the right distal common carotid artery far wall in computer image processed B-mode ultrasonograms obtained at baseline and every 6 months during the 2-year trial. RESULTS In a multivariable mixed-effects model, among women who had at least one follow-up measurement of carotid intima-media thickness (n = 199), the average rate of progression of subclinical atherosclerosis was lower in those taking unopposed estradiol than in those taking placebo (-0.0017 mm/y vs. 0.0036 mm/y); the placebo-estradiol difference between average progression rates was 0.0053 mm/y (95% CI, 0.0001 to 0.0105 mm/y) (P = 0.046). Among women who did not receive lipid-lowering medication (n = 77), the placebo-estradiol difference between average rates of progression was 0.0147 mm/y (CI, 0.0055 to 0.0240) (P = 0.002). Average rates of progression did not differ between estradiol and placebo recipients who took lipid-lowering medication (n = 122) (P > 0.2). CONCLUSIONS Overall, the average rate of progression of subclinical atherosclerosis was slower in healthy postmenopausal women taking unopposed ERT with 17beta-estradiol than in women taking placebo. Reduction in the progression of subclinical atherosclerosis was seen in women who did not take lipid-lowering medication but not in those who took these medications.

Abstract
OBJECTIVE To assess the extent of accumulation of circulating estrone (E1), total and free estradiol (E2) and estrone sulfate (E1S) levels in postmenopausal women receiving prolonged oral E2 therapy and to determine the effect of increased estrogenicity on free testosterone levels. STUDY DESIGN Descriptive study involving 14 healthy postmenopausal women during a three-year period. Group 1 (n = 7) took a placebo. Group 2 (n = 7) took 1 mg micronized E2 daily. Blood samples were taken at one, two and three years. E2, E1 and total testosterone were quantified by radioimmunoassay (RIA) following extraction and celite chromatography. Free testosterone and E2 were calculated. Sex hormone-binding globulin (SHBG) and E1S were quantified by RIA. RESULTS In the control group, none of the hormone levels changed significantly. Free testosterone decreased 49% in women taking E2 replacement as compared to a 7% decline in women taking placebo. In women taking E2 replacement, E1, E2, E1S, free E2 and SHBG levels increased 10, 6, 51, 2 and 2 times, respectively, between baseline and year 3. CONCLUSION E1, E2 and E1S levels significantly increased with E2 replacement. Free testosterone levels decreased with E2 replacement. Testosterone replacement may be warranted when giving postmenopausal women estrogen replacement therapy.

Abstract
OBJECTIVE To compare serum estrone sulfate (E1S) levels in postmenopausal women during long-term treatment with commonly prescribed doses of oral and transdermal estradiol (E2). DESIGN A retrospective study performed in a University setting in the United States involving 33 healthy postmenopausal women. Two groups of postmenopausal women were studied: group 1 (n = 10) received 1 mg oral micronized E2 daily for 16 months; blood was drawn at 0, 7, and 15 months. Group 2 (n = 23) was randomized into three subgroups. Two of the subgroups (n = 8; n = 7) received E2 delivered at a rate of 0.05 mg/day and 0.1 mg/day, respectively, by transdermal patch, changed twice weekly; the third subgroup received a placebo (without E2) patch for 9 continuous months. Blood samples were drawn at 0, 6, and 9 months. Serum E1S and E2 were quantified by specific radioimmunoassays. Statistical analysis was performed by analysis of variance. RESULTS After oral E2 treatment, E1S levels increased significantly (p < 0.01) from baseline, reaching an average level of 38.8 ng/mL at 15 months. After transdermal E2 treatment, E1S levels increased significantly, yet to a much lesser extent, reaching levels of 1.8 ng/mL and 3.2 ng/mL after 9 months of treatment with the 0.05 mg/day and 0.1 mg/day patches, respectively. CONCLUSIONS Markedly elevated levels of E1S were found after long-term oral estrogen treatment. In comparison to the increase in E1S levels after long-term oral estrogen treatment, there was only a small increase in E1S levels after transdermal E2 therapy. This difference may be attributed to the higher dosage of oral E2 that is required because of the low bioavailability compared with the transdermal dosages.

Abstract
OBJECTIVE To evaluate the efficacy of lower doses of conjugated equine estrogens (CEE) plus medroxyprogesterone acetate (MPA) for relieving vasomotor symptoms and vaginal atrophy. DESIGN A randomized, double-blind, placebo-controlled trial (the Women's Health, Osteoporosis, Progestin, Estrogen study). SETTING Study centers across the United States. PATIENT(S) Two thousand, six hundred, seventy-three healthy, postmenopausal women with an intact uterus, including an efficacy-evaluable population (n = 241 at baseline). INTERVENTION(S) Patients received for 1 year (13 cycles; in milligrams per day) CEE, 0.625; CEE, 0.625 and MPA, 2.5; CEE, 0.45; CEE, 0.45 and MPA, 2.5; CEE, 0.45 and MPA, 1.5; CEE, 0.3; CEE, 0.3 and MPA, 1.5; or placebo. MAIN OUTCOME MEASURE(S) Number and severity of hot flushes and Papanicolaou smear with vaginal maturation index (VMI) to assess vaginal atrophy. RESULT(S) In the efficacy-evaluable population, reduction in vasomotor symptoms was similar with CEE of 0.625 mg/d and MPA of 2.5 mg/d (the most commonly prescribed doses) and all lower combination doses. CEE of 0.625 mg/d alleviated hot flushes more effectively than the lower doses of CEE alone. VMI improved in all active treatment groups. CONCLUSION(S) Lower doses of CEE plus MPA relieve vasomotor symptoms and vaginal atrophy as effectively as commonly prescribed doses.

Abstract
The introduction of new products, lower dosages, and better continuous and cyclic regimens allows for individualized treatment aimed at minimizing risk and side effects, while maximizing confidence and compliance. Since the major side effect of HRT that discourages long-term use is vaginal bleeding, newer regimens are designed to minimize it. The lowest doses of estrogen currently approved by the FDA for prevention of osteoporosis include 0.3 mg esterified estrogens, 0.025 microg transdermal estradiol patch, and 0.5 mg micronized estradiol. In most naturally menopausal women or those over 65 years of age, conjugated estrogen 0.3 mg (with adequate calcium intake) is protective against bone loss and cardiovascular disease. These low doses are often used with cyclic progestins every 3 to 4 months. Advantages of cyclic therapy using low-dose estrogen include minimal progestin exposure, low rate of withdrawal bleeding, lowered side effects, and, often, higher comfort level. Cyclic estrogen regimens with higher doses have been in use longer, but they often necessitate more frequent progestin treatment and may result in cyclic bleeding or breast tenderness. While HDL- and LDL-cholesterol changes are greater and more beneficial during higher-dose oral cyclic therapy, the large increase in triglycerides is of concern. The most commonly used continuous combined regimens include conjugated estrogen plus daily progestin orally or the combination estradiol/norethindrone acetate transdermal patch. Continuous combined regimens are simple and easy-to-use, and are designed to minimize bleeding. Multiple studies suggest that the mechanism of benefit provided by estrogen goes beyond estrogen's favorable impact on lipoproteins, which is blunted by daily use of synthetic progestins.

Abstract
BACKGROUND AD, the most prevalent cause of dementia, affects twice as many women as men. Therapeutic options are limited, but results of prior studies support the hypothesis that estrogen treatment may improve symptoms of women with this disorder. METHODS Forty-two women with mild-to-moderate dementia due to AD were enrolled into a randomized, double-blind, placebo-controlled, parallel-group trial of unopposed conjugated equine estrogens (1.25 mg/day) for 16 weeks. RESULTS Outcome data were available for 40 women at 4 weeks and 36 women at 16 weeks. At both 4 and 16 weeks, there were no significant differences or statistical trends between treatment groups on the primary outcome measure (the cognitive subscale of the Alzheimer's Disease Assessment Scale), clinician-rated global impression of change, or caregiver-rated functional status. Exploratory analyses of mood and specific aspects of cognitive performance also failed to demonstrate substantial group differences. CONCLUSION Although conclusions are limited by small sample size and the possibility of a type II error, results suggest that short-term estrogen therapy does not improve symptoms of most women with AD. These findings do not address possible long-term effects of estrogen in AD, possible interactions between estrogen and other treatment modalities, or putative effects of estrogen in preventing or delaying onset of this disorder.

Abstract
Although the association between postmenopausal hormone use and breast cancer has not been clarified, there is nothing indefinite about the survival advantage conferred by hormone replacement therapy. Cardiovascular and fracture-related deaths so outnumber breast cancer deaths that even women with family histories of the latter are likely to benefit from low-potency estrogen replacement.

Abstract
Osteoporosis is a common problem, affecting >28 million Americans, >/=75% of whom are postmenopausal women. In 1995 the cost of caring for patients with complications of osteoporosis was $14 billion. Of the 1.5 million osteoporotic fractures that occur in this country each year, the most serious are hip fractures. It is estimated that approximately 10% to 20% of women die within a year after a hip fracture. Numerous studies reveal that although osteoporotic fractures are preventable most women are not receiving or choosing to receive the medical care that they need to prevent them. Great strides have been made in establishing the importance of ovarian hormones in not only the pathophysiology but also the treatment of postmenopausal osteoporosis. Clinical studies show that estrogen and estrogen-androgen replacement therapies both prevent the development of osteoporosis, as determined by bone mineral density determinations and bone marker analyses. The addition of an androgen to hormone replacement therapy may prevent bone loss and stimulate bone formation.

Abstract
To determine the safety of transcervical administration of quinacrine pellets as a method of voluntary female sterilization, three noncomparative Phase I clinical trials of the administration of 250 mg quinacrine were carried out in 21 women who were scheduled to undergo hysterectomy 24 h or one month later. Detailed results are presented for one of the trials using 10-min pellets. Six of 10 women had minor transitory complaints during the postinsertion 24-h follow-up period. Five women reported pelvic/abdominal cramping, one experienced headache, and one experienced dizziness. Blood chemistry values were not adversely influenced by the quinacrine. The average plasma level of quinacrine peaked at 3 h, 36.1 ng/ml, slightly lower than the value observed 4 h after oral administration of 200 mg in a previous study. An average of 27% of the administered dose was recovered in tampons. Quinacrine was detected in the plasma of two women at the four/six-week visit. Selected results are presented from two other trials that were halted because of slow recruitment. The transcervical administration of 250 mg of 10-min quinacrine pellets was well tolerated. However, based on recent mutagenicity testing and meetings with regulatory officials, it appears unlikely that the use of quinacrine for nonsurgical sterilization could be approved in the United States or Europe.

Abstract
Contraceptive technology has recently provided the market place with new barrier methods, new progestin oral contraceptives, an injectable contraceptive, the female condom, new male condoms, and the contraceptive implant. During the last decade, epidemiologists have clearly defined the non-contraceptive benefits of current contraceptive methods that include decreased infections, protection from various cancers, protection from many gynecologic problems that lead to surgery, as well as symptomatic relief from many gynecologic conditions. In conjunction with medical specialists, contraceptive researchers have established the increased safety and benefits of various contraceptive choices in women with medical conditions that, until recently, were contra-indications for their use. That these advances have occurred despite multiple legal and scientific assaults gives hope that the field will continue to grow.

Abstract
OBJECTIVE To evaluate central opioid activity in women with prospectively documented premenstrual syndrome (PMS) and control women in the mid- and late luteal phases of the menstrual cycle. METHODS Blood was collected every 15 minutes 1 hour before (0800) and 2 hours after treatment (0900-1100). The treatment was administered in a randomized fashion and consisted of naloxone 1 or 4 mg or placebo, and blood was assayed for luteinizing hormone (LH). Baseline estradiol, progesterone, and prolactin were measured at 0800 and 0900 hours. RESULTS There was a significant increase in LH area under the curve and mean LH in response to naloxone in the midluteal phase in the control (P < .001). The PMS subjects did not display a significant increase in LH concentration in response to naloxone in the midluteal phase. There were no significant LH responses to naloxone in either group in the late luteal phase. There were no significant differences in estradiol, progesterone, or prolactin concentrations or estrogen to progesterone ratios between groups. CONCLUSION Control women have an enhanced central opioid tone during the midluteal phase that diminishes and becomes minimal in the late luteal phase of the menstrual cycle. In contrast, women with PMS have a loss of central opioid tone during the midluteal phase as indicated by the loss of LH response to naloxone. This attenuated central opioid tone in women with PMS as compared with asymptomatic control women may play a role in the pathophysiology of PMS.

Abstract
A core design contraceptive vaginal ring (CVR) releasing 650 mcg of norethindrone acetate (NA) and 10, 20, 30 or 65 mcg of ethinyl estradiol (EE) daily was developed and tested in 99 women. The CVR inhibited ovulation well with 30 or 65 mcg EE. Vaginal bleeding was better controlled than in 23 control women using NA/EE oral contraceptives. Side effects were comparable to controls for the 20 and 30 mcg EE CVR. The 65 mcg EE CVR resulted in an unacceptably high level of nausea. The 20 and 30 mcg EE CVR caused an increase in serum HDL cholesterol and triglycerides. Total cholesterol was unchanged. Angiotensinogen and sex hormone binding globulin-binding capacity were increased in a subgroup of the 20 and 30 mcg EE CVR subjects, similar to that of 20 controls using EE/gestodene oral contraceptives. This new CVR offers an excellent contraceptive alternative with the best performance provided by the 30 mcg EE dose.

Abstract
OBJECTIVE To test the effectiveness and safety of long-term depot leuprolide acetate (GnRH-a) plus estrogen and progestin add-back therapy in the treatment of moderate and severe premenstrual syndrome (PMS). DESIGN A prospective trial with each patient serving as her own control. SETTING University teaching hospital. PARTICIPANTS Ten women with regular menstrual cycles complaining of moderate to severe PMS. Premenstrual syndrome was diagnosed when symptoms increased > or = 25% during the luteal phase. TREATMENT Four-week cycles of IM injections of placebo or GnRH-a with all patients receiving saline (placebo), the first cycle followed by 12 cycles of GnRH-a, 7.5 mg. Conjugated equine estrogen (0.625 mg/d) was started Monday through Saturday within the first cycle and increased as needed. Medroxyprogesterone acetate (MPA), 10 mg/d, was taken orally for 10 days after 4, 8, and 12 cycles of GnRH-a therapy. MAIN OUTCOME MEASURES Changes in three symptom categories (water retention, pain, and psychological function), serum levels of total cholesterol and HDL, HDL-2, and LDL cholesterol, E2, and estrone. Endometrial biopsy was obtained 1 day after the end of the 12th GnRH-a cycle, and bone density was assessed using quantitative computer tomography at the end of the 12th GnRH-a cycle. RESULTS During treatment, there was a significant decrease compared with baseline and placebo in all three symptom categories. There were no significant changes in lipids. Endometrial biopsies revealed progestational changes with no evidence of hyperplasia. Quantitative computer tomography bone density dropped 3.7 on average compared with baseline after 12 months of treatment, but this was not statistically significant. CONCLUSION Gonadotropin-releasing hormone agonist therapy with hormonal add-back therapy is effective in treating PMS symptoms with progressive improvement over a 12-month period. This therapy prevents changes in lipids and adequately protects the endometrium with the addition of MPA every 4th cycle. Quantitative computer tomography bone density dropped at 12 months; further examination of bone changes is necessary.

Abstract
OBJECTIVE To compare a new triphasic oral contraceptive (OC) containing desogestrel and ethinyl estradiol (DSG/EE) with triphasic norethindrone/ethinyl estradiol (NE/EE) regarding effects on clinical efficacy, cycle control, and safety indices. METHODS In an open-label, comparative multicenter study, 407 subjects were randomized to a triphasic preparation containing DSG/EE and 405 subjects to a triphasic preparation containing NE/EE. The women were observed during six cycles of OC use. RESULTS The contraceptive efficacy of the triphasic DSG/EE OC was at least comparable to that of triphasic NE/EE. No pregnancies were reported with DSG/EE, whereas there were two pregnancies with NE/EE, both user failures. Cycle control with triphasic DSG/EE was statistically superior to that with triphasic NE/EE. Acceptability was excellent with both preparations as measured by the low discontinuation rates (particularly for adverse menstrual experiences). No thromboembolic or other serious drug-related adverse experiences were reported. The incidence of other drug-related adverse experiences was generally low and decreased with time in both groups. No adverse effects were seen in terms of blood pressure, body weight, laboratory indices, cervical cytology, and breast nodularity. CONCLUSION Triphasic DSG/EE is an effective and safe OC with excellent acceptability and cycle control superior to that of triphasic NE/EE.

Abstract
Gestodene, one of three new gonane progestins, is the most potent on a per weight basis in regard to progestational effects and has little or no estrogenic effect. In in vivo animal studies, gestodene also has less androgenic activity compared with progestins found in older combination oral contraceptive formulations. It binds to mineralocorticoid receptors and consequently is a competitive aldosterone inhibitor, leading to speculation that it may be beneficial in hypertensive patients. Numerous large clinical trials have shown that the combination of gestodene and ethinyl estradiol is as effective in preventing pregnancies as other oral contraceptives presently on the market. Irregular bleeding and spotting rates appear to be at least as good as older formulations. In general, studies show that the incidence of side effects associated with the progestin and estrogen components tends to be low, with very little impact on lipid and carbohydrate metabolism. Gestodene-containing oral contraceptives have been associated with small increases in clotting factors, generally because of the estrogen component, with compensatory changes in the fibrinolytic system. Although gestodene-containing oral contraceptives have been used in Europe since 1987, they have not been available in the United States except for use in clinical trials. At present, a triphasic formulation containing 50 to 100 micrograms of gestodene plus 30 to 40 micrograms of ethinyl estradiol is awaiting approval by the Food and Drug Administration.

Abstract
BACKGROUND It has been known for some time that oral contraceptives substantially reduce the risk of endometrial and ovarian cancer, but they do not reduce the risk of breast cancer. A hormonal contraceptive regimen has been developed which uses a gonadotropin-releasing hormone against (GnRHA) to suppress ovarian function, and this regimen includes the administration of very low doses of both estrogen and progestogen. This hormonal contraceptive regimen attempts to minimize exposure of the breast epithelium to these steroids and to preserve the maximum beneficial effects of estrogen, while still preventing endometrial hyperplasia. PURPOSE Our purpose was to determine whether changes occurred in mammographic densities between baseline and 1 year for women on this hormonal contraceptive regimen with reduced estrogen and progestogen levels compared with women in a control group. METHODS Twenty-one women were randomly assigned in a 2:1 ratio to the GnRHA-based contraceptive group (14 women) or to a control group (seven women). The contraceptive group received the following: 7.5 mg leuprolide acetate depot by intramuscular injection every 28 days; 0.625 mg conjugated estrogen by mouth for 6 days out of 7 every week; and 10 mg medroxyprogesterone acetate orally for 13 days every fourth 28-day cycle. The control group received no medication. Baseline and 1-year follow-up mammograms of contraceptive and control subjects were reviewed in a blinded fashion by two radiologists. RESULTS Comparison of the changes between the baseline and 1-year mammograms in the two groups of women showed significant (P = .039) reduction in mammographic densities at 1 year for women on the contraceptive regimen. Assessing the reduction in mammographic densities by noting the fineness of fibrous septae showed a highly significant (P = .0048) difference in the contraceptive regimen group. One of the women on the contraceptive regimen was withdrawn from the study because of poor compliance. CONCLUSION The reduced estrogen and progestogen exposures to the breast that were achieved by the hormonal contraceptive regimen resulted in substantial reductions in follow-up mammographic densities at 1 year compared with baseline. Although there is no direct evidence that such a reduction in densities will lead to a reduced risk of breast cancer, indirect evidence for a protective effect of this regimen is that early menopause reduces breast cancer risk, and that menopause is associated with a reduction in mammographic densities.

Abstract
Luteal phase defects are defined as disorders resulting from abnormal corpus luteum function associated with insufficient progesterone production. The incidence is difficult to estimate accurately, but the disorder may affect 3-4% of infertile couples. Candidates for screening are those with unexplained infertility or recurrent abortion. Blood samples should be obtained seven to nine days after ovulation as determined by the thermogenic shift on basal body temperature monitoring or by a urinary luteinizing hormone surge. A midluteal phase serum progesterone level < 10 ng/mL is suggestive of the diagnosis. Endometrial biopsies are indicated in those couples with unexplained infertility and recurrent abortion, particularly if progesterone levels are > 10 ng/mL. While there have been few comparative studies, the four treatments available are clomiphene citrate, progesterone vaginal suppositories, human menopausal gonadotropins and bromocriptine. Because of its simplicity of use, clomiphene citrate is the recommended first-line treatment.

Abstract
BACKGROUND Several case-control studies suggest that the male condom protects women against some sexually transmitted diseases. The female condom is the first barrier device under the woman's control that may be effective in the prevention of sexually transmitted diseases. GOAL OF THIS STUDY To determine if appropriate use of the female condom decreased the rate of recurrent vaginal trichomoniasis in previously diagnosed and treated women. STUDY DESIGN One hundred and four sexually active women with vaginal trichomoniasis were treated with metronidazole and assigned to a group using the female condom or a control group during a 45-day period of continued sexual activity. Fifty women served as controls, and 54 women were assigned to use the female condom. RESULTS Only 20 women used the female condom each time they had sexual intercourse. Reinfection with trichomonas occurred in 7/50 (14%) controls, in 5/34 (14.7%) noncompliant users, and in 0/20 compliant users of the female condom. CONCLUSION The compliant use of the female condom is effective in preventing recurrent vaginal trichomoniasis.

Abstract
Combination oral contraceptive (COC) users have reduced risks of ovarian and endometrial cancer, but COCs have not reduced breast cancer risk. We have previously argued that a hormonal contraceptive with substantially lower doses of sex-steroids should reduce breast cancer risk by decreasing the breast epithelial cell proliferation below usual premenopausal levels. We report here the preliminary results of a pilot trial with such a prototype contraceptive consisting of an agonist of gonadotropin releasing hormone (GnRHA) administered with low doses of an oral estrogen (0.625 mg of conjugated estrogen, CE, for 6 days every week) and intermittent oral progestogen (10 mg of medroxyprogesterone acetate, MPA, for 13 days every 4 months). Eighteen subjects at five-fold or greater increased breast cancer risk were entered and randomized -12 to the contraceptive arm and 6 to a control arm. The principal endpoints included tolerance of the regimen, vaginal bleeding patterns, and the regimen's effect on the endometrium, bone metabolism, and lipids. A symptom questionnaire was used to assess tolerance; the contraceptive subjects had fewer symptoms following initiation of the regimen. This results from the elimination of symptoms associated with the luteal phase of the menstrual cycle, commonly referred to collectively as premenstrual syndrome, PMS. The few occurrences of hot flushes or vaginal dryness that did occur were eliminated by small increases in estrogen dose (0.9 mg CE). Scheduled vaginal bleeding occurred associated with most periods of progestogen administration. Unscheduled bleeding or spotting was infrequent and decreased with time on the regimen. A beneficial rise in high-density lipoprotein cholesterol was evident in the contraceptive subjects. Despite the use of an estrogen dose which is known to prevent loss of bone mineral density in normal postmenopausal women, an annualized loss of 1.9% was seen in contraceptive subjects. It is hypothesized that this is secondary to inhibition of ovarian androgen production by the GnRHA, which may additionally account for changes in libido occasionally reported with GnRHA. The study continues with the addition of a small dose of androgen to replace that lost by the action of the GnRHA.

Abstract
Associated with progesterone and the synthetic progestins used in oral contraceptives is a dose-dependent impairment of carbohydrate metabolism. It is well known that in the general population hyperinsulinemia and alterations in glucose metabolism are significant risk factors for the development of cardiovascular disease. Studies that use curve analysis of glucose tolerance tests have demonstrated insulin resistance, rises in plasma insulin, and relative glucose intolerance in women using oral contraceptives. Desogestrel, a new progestin, has been demonstrated to have generally less pronounced effects on these parameters of carbohydrate metabolism.

Abstract
Gonadotrophin-releasing hormone agonists (GnRHAs) were investigated as contraceptive agents from the late 1970's to the mid-1980's. They were abandoned as they appeared to offer no advantage over conventional combination-type oral contraceptives (COCs). This conclusion appears to be incorrect. We propose here a contraceptive regimen of a depot formulation of a GnRHA plus add-back estrogen and intermittent progestogen. The dose of add-back sex-steroids is substantially less than that in COCs; this reduction in sex-steroids should lead to a major reduction in lifetime breast cancer occurrence.

Abstract
A group of 15 postmenopausal women who had not recently received estrogen replacement were enrolled in a study during which they received 0.625 mg of conjugated equine estrogen and 2.5 mg of medroxyprogesterone acetate daily from Monday through Friday of each week for six months. No treatment was given on the weekend. Endometrial biopsy specimens at the end of therapy revealed minimal growth of glands and stroma and a low mean mitosis count. Of the 12 women who completed the trial, 5 were completely amenorrheic, and only 4 of the 15 bled beyond the second month of treatment. Of those four, two spotted for only a few days. In the 12 women who completed the trial there was a significant increase in high density lipoprotein cholesterol and a nonsignificant lowering of low density lipoprotein cholesterol. The results of this study indicate that comparative trials between this regimen and one in which the two drugs are given daily for seven days a week are warranted.

Abstract
Daily transvaginal ultrasound (US) scanning of the ovaries to assess follicular development and daily blood sampling were performed on 19 Norplant (Leiras, Turku, Finland) subdermal contraceptive implant users who had regular menstrual cycles and on 10 normally cycling women. Three groups were identified in the implant users based on US finding. Six (31.6%) of the implant users had US findings that were consistent with a normal ovulatory pattern. However, their mean peak luteinizing hormone levels and peak midluteal phase progesterone (P) levels were significantly lower than control values. Eleven (57.9%) users had persistent follicles, and 2 users (10.5%) had no follicular development. These data suggest that after 2 to 4 years of use, about one third of Norplant users with regular bleeding patterns may ovulate but most have deficient luteal P levels. In this small study, the presence of persistent follicular enlargement in implant users was common.

Abstract
The purpose of this study was to examine the bleeding patterns of 234 Norplant users during 5 years of use and to identify the bleeding patterns of users who conceived. During the first year of use, 26.6% of users had regular bleeding cycles, 66.3% had irregular cycles, and 7.1% were amenorrheic. By the fifth year of use, 62.5% of users had regular cycles, 37.5% had irregular cycles, and none had amenorrhea. Of the ten users who became pregnant, eight had regular menstrual cycles in the 6 months before the diagnosis of pregnancy, one had an irregular pattern, and one did not keep a bleeding record. None had amenorrhea. The 5-years cumulative pregnancy rate for patients with regular cycles was 17.4%; this was significantly higher (P less than .05) than the 5-year cumulative rates of 4.4% in users with irregular cycles and 0% in users with amenorrhea. This study indicates that during the first year of Norplant use, only 26.6% of users have regular cycles, but after the first year, 50-60% of users develop regular cycles. The bleeding patterns of women using Norplant improve after the first year of use, and those with regular cycles are at greatest risk for method failure.

Abstract
Mifepristone (RU 486), a synthetic steroid with antiprogesterone receptor activity, was given with and without naloxone hydrochloride to six women in the midluteal phase to investigate the role of progesterone in the modulation of endogenous opioid activity and the secretion of luteinizing hormone and cortisol. Subjects were evaluated during four sequential monthly admissions during which multiple blood samples were obtained every 15 minutes for 8 hours. Patients were studied during a baseline cycle, after administration of RU 486 alone (100 mg/day), naloxone with RU 486, and naloxone alone. After administration of RU 486 there was a significant decline in total luteinizing hormone secretion (p less than 0.01) and luteinizing hormone pulse amplitude (p less than 0.05), but compared with baseline there was no significant change in luteinizing hormone pulse frequency. After infusion of naloxone there was a significant increase in mean luteinizing hormone values (p less than 0.05) and luteinizing hormone pulse frequency (p less than 0.01) but no change in pulse amplitude. There was no significant difference in mean luteinizing hormone values or luteinizing hormone pulse amplitude and frequency between administration of RU 486 and naloxone plus RU 486. Administration of naloxone alone, RU 486 alone, and RU 486 plus naloxone caused a significant increase in cortisol as compared with baseline cycles (p less than 0.05). These data further support the notion that progesterone is important in the control of luteinizing hormone secretion and suggest that progesterone may primarily influence luteinizing hormone pulse amplitude and pituitary release of luteinizing hormone during the luteal phase.

Abstract
Women with recent gestational diabetes mellitus were randomly assigned to one of two low-dose oral contraceptives to evaluate the effect of low-dose oral contraceptives on carbohydrate and lipid metabolism. A cohort of similar women requesting a non-oral-contraceptive method served as controls. The two oral contraceptives studied were ethinyl estradiol (0.035 mg)-norethindrone (0.40 mg) and ethinyl estradiol (0.030 to 0.040 mg)-levonorgestrel (0.050 to 0.125 mg). A 75 gm, 2-hour oral glucose tolerance test and a fasting lipid profile (total cholesterol, triglyceride, high- and low-density lipoprotein cholesterols) were performed at entry, after 3 months, and after 6 to 13 months of treatment. The prevalence of diabetes at 6 to 13 months (27/156 patients) was not significantly different between groups (non-oral-contraceptive group, 17%; ethinyl estradiol-norethindrone, 15%; ethinyl estradiol-levonorgestrel, 20%). When examined by prior gestational diabetes mellitus class, diabetes mellitus was present in 7% of prior class A1 and 29% of women with prior class A2 disease (p less than 0.001). Mean cholesterol and low-density lipoprotein cholesterol levels were significantly improved in all three groups at 3 months and at 6 to 13 months, whereas triglycerides remained unchanged. There were no differences in cholesterol, low-density lipoprotein cholesterol, or triglycerides levels between the groups. After 6 to 13 months, there was a significant increase in high-density lipoprotein cholesterol in the ethinyl estradiol-norethindrone group compared with the ethinyl estradiol-levonorgestrel and non-oral-contraceptive groups.

Abstract
An intrauterine device, releasing approximately 20 micrograms/day of levonorgestrel (LNg 20), used by 1124 women, was studied in a randomized trial of five years duration in comparison with the Copper T, model TCu 380Agm in 1121 women. At five years, the gross cumulative pregnancy rate of 1.1 +/- 0.5 per 100 among users of the LNg 20 devices was not significantly different from the rate of 1.4 +/- 0.4 per 100 experienced by users of the Copper T 380Ag. The steroid-releasing IUD had significantly higher termination rates for expulsion and amenorrhea, a significantly lower termination rate for other menstrual problems and pain, and a lower continuation rate. The five-year continuation rate among women using the TCu 380Ag was 40.6 per 100 as compared with that of 33.0 per 100 among women randomized to the LNg 20 device (P less than .001). Terminations attributed to amenorrhea with the LNg device primarily account for differences in continuation. These two intrauterine devices are the most effective long-term, reversible IUDs yet reported in the literature. No other contraceptive methods have exhibited such low long-term pregnancy rates in randomized comparative trials.

Abstract
The experience of 271 patients who received mifepristone (RU 486) in experimental protocols from July 1984 to January 1989 was analyzed by logistic regression methods. The regimen used was the strongest predictor of failure, followed by Quetelet's index and initial beta-human chorionic gonadotropin level. The relative risk of failure was 2.3 times with 7-day regimens and 6.3 times with the other regimens that obtained with regimens of 600 mg given once or twice. The relative risk of failure increased with increasing Quetelet's index; women in the top quartile were 2.9 times more likely to fail to abort than were women in the bottom quartile. The risk of failure increased with increasing initial beta-human chorionic gonadotropin level; those with an initial level greater than 19,800 mIU/ml were 2.8 times more likely to fail to abort than were women with an initial value less than or equal to 6350 mIU/ml. Body mass appears to influence the likelihood of abortion with mifepristone.

Abstract
Norplant offers long-term contraception through the use of subdermal capsules filled with levonorgestrel. The six capsules are implanted in the inside part of the upper arm. The levonorgestrel is released from the capsules gradually, providing contraception for about 5 years. The primary mechanism of action of Norplant is suppression of ovulation. Studies have shown a pregnancy rate of 0.6/100 woman-years after 1 year and a cumulative rate of 1.5/100 woman-years at 5 years. Principal side effects are irregular menstrual bleeding and headaches. No changes in carbohydrate metabolism, blood coagulation, or liver function have been reported. Lipid levels have decreased 5% to 15%. After removal of Norplant, fertility returns rapidly, and there have been no adverse effects on infants. Norplant is currently approved in 12 countries; clinical trials are being conducted in 37 countries.

Abstract
Dating of maturity of the endometrium by histologic examination was correlated with four methods of ovulation detection in 13 cycling parous women. Histologic dating was assessed independently by two pathologists and correlated with the postovulatory duration as determined by daily transvaginal ultrasound scanning, serum LH measurements, basal body temperature (BBT), and subtraction of 14 days from the onset of menses. In addition, progesterone and estradiol (E2) were measured in daily serum samples. Dating of the endometrial biopsy was highly correlated (P less than .002) with the day of ovulation as determined by ultrasound, and was found to be within 2 days of the correct postovulatory day on evaluation of 25 of 26 (96.1%) of the interpretations. The accuracy of dating using the LH surge was 84.6% (22 of 26 interpretations), and with the BBT thermogenic shift was 76.9% (20 of 26 interpretations). However, dating of the endometrium was within 2 days of the correct day in only 17 of the 26 interpretations as determined by subtracting 14 days from the onset of the subsequent menses. The accuracy of dating was significantly better correlated (P less than .025) with days from ovulation as determined by ultrasound than as calculated from the onset of menses. There was a significant correlation between endometrial dating and the amount of progesterone (P less than .01) and E2 (P less than .01) secreted from the day of ovulation, as determined by transvaginal ultrasound, to the day of biopsy. These data confirm a strong correlation between endometrial dating and ovarian hormone secretion during the postovulatory phase.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
We compared the transdermal and subdermal routes of estrogen administration with respect to the constancy of estrogen delivery and metabolic effects. Twenty postmenopausal women were randomized to receive either two 25 mg estradiol pellets subdermally (n = 10) or a 0.1 mg estradiol transdermal patch twice weekly (n = 10). Blood was sampled at 0, 2, 4, 6, 8, 12, 24, and 72 hours and 1, 2, 4, 8, 12, 16, 20, and 24 weeks (fasting samples at 0, 12, and 24 weeks), and a fasting urine was obtained after diuresis at 0, 12, and 24 weeks. In a 72-hour profile, serum estradiol levels (mean +/- SE) were highest at 24 hours (179 +/- 20 pg/ml) and fell to 139 +/- 16 pg/ml at 72 hours in the pellet group. In the patch group, estradiol levels rose rapidly to 152 +/- 33 pg/ml at 4 hours, remained relatively constant over 8 hours, and fell to 46 +/- 10 pg/ml at 72 hours. At 1 week, estradiol levels in the pellet group were 113 +/- 12 pg/ml and remained relatively constant for 24 weeks. In contrast, estradiol levels in the patch group were 52 +/- 11 pg/ml at 1 week and then varied widely until 24 weeks, when the levels were 89 +/- 26 pg/ml. The mean estradiol/estrone ratio ranged between 1 and 2.5 in both groups but fluctuated widely in the patch group. Follicle-stimulating hormone was suppressed in both groups; however, the decrement in the pellet group was greater (p less than 0.002). There was a significant increase in high-density lipoprotein cholesterol and a decrease in total cholesterol/high-density lipoprotein cholesterol at 12 weeks with the pellet but only at 24 weeks with the patch. The urinary calcium/creatinine ratio was reduced more consistently with the pellet than with the patch. Hot flushes were eliminated in all subjects.

Abstract
RU-486 is a synthetic progesterone antagonist that is abortifacient in early pregnancy. This trial evaluated the effectiveness and safety of a single 600 mg oral dose given to 50 healthy women less than or equal to 49 days from their last menstrual period. Efficacy was inversely related to the initial beta-subunit of human chorionic gonadotropin level, ranging from 100% at less than 5000 mIU/ml to 81% at greater than 20,000 mIU/ml (p less than 0.05). Uterine bleeding was the most serious side effect. However, the mean change in the hemoglobin value 14 days after treatment was -0.4 gm/dl, and no patient required blood transfusion. This regimen appears to be simple, effective, and safe.

Abstract
RU 486, a synthetic steroid with antiprogesterone receptor activity, was used to investigate the importance of progesterone on gonadotropin secretory dynamics in the midcycle of the normal menstrual cycle. Six normally cycling women were followed for three consecutive cycles. During each cycle, blood samples were obtained beginning on day 10 and continued until menses. After a control cycle, 100 mg RU 486 was given orally between days 10 and 17. The patients were followed for a posttreatment cycle with no medication. When RU 486 was given before the midcycle, the luteinizing hormone surge was delayed by 15.0 +/- 2.1 days after ingestion of the last pill, resulting in cycles of 40.6 +/- 2.6 compared with 28.0 +/- 2.3 days (p less than 0.01). During RU 486 administration and at the time a normal luteinizing hormone surge was anticipated, an attenuated luteinizing hormone/follicle-stimulating hormone surge was noted that was not followed by a rise in progesterone. After the attenuated surge a normal luteinizing hormone/follicle-stimulating hormone level occurred, with a normal rise in progesterone. Estradiol levels during RU 486 administration decreased during treatment, indicating a possible direct action of RU 486 on the ovary.
