To compare the effect of different formulations of continuous combined hormone therapy on sexual performance in naturally postmenopausal women.
                A total of 158 postmenopausal women were enrolled and prospectively randomized to the single-blind study. Fifty-four women received tibolone 2.5 mg, 53 received 2 mg estradiol and 2 mg dienogest (E2/dienogest), and 51 did not receive any menopausal therapy. The patients were monitored after 6 months. Attitudes of sexuality were evaluated by using the Rosen's female sexual function index.
                Compared with E2/dienogest and the control group, tibolone treatment was associated with more improvement of sexual performance, including sexual desire, sexual arousal and satisfaction. Both of the hormone therapies decreased frequencies of vaginal dryness and painful intercourse.
                Tibolone has more positive effects on the sexual dysfunction of postmenopausal women and may be an alternative to the E2/dienogest preparation in postmenopausal women with sexual dysfunction. To compare the effects of two different postmenopausal regimens on sexual performance.
                A single blind prospective clinical study was planned on fifty natural postmenopausal women with no absolute contraindication for hormone replacement therapy (HRT). A total of 25 women were randomized for tibolone therapy (group T) and the rest 25 for continuous conjugated estrogen (CE) 0. 625 mg plus medroxyprogesterone acetate (MPA) 2.5 mg (group E) for a year. Two women in group T and four women in group E were excluded from the study as they didn't attend the control visit. At baseline and after a year, sexual performance parameters (sexual desire, coital frequency, orgasm frequency, vaginal dryness/dyspareunia) and after therapy subjective well-being, vasomotor symptoms, and side effects were assessed by score method designed by us.
                Treatment with either preparation significantly improved subjective well-being, vasomotor symptoms and vaginal dryness. The rates of overall side effects between two groups were not found statistically different (P=0.84). Tibolone therapy increased sexual desire and coital frequency (P=0.001, P=0.014).
                Both tibolone and continuous combined CE/MPA effectively improve the findings of hypoestrogenism and subjective well being. Moreover, tibolone effectively increases sexual performance. It is seen that tibolone with acceptable androgenic side effects can be an appropriate selection for HRT in postmenopausal women with decreased sexual desire. To evaluate the benefits and risks of hormone replacement therapy (HRT) combined with methyltestosterone (MT) in postmenopausal women with sexual dysfunction.
                This study was a randomized, double-blind, placebo-controlled and crossover trial. Eighty-five women using HRT were divided into four treatment groups: GI-HRT plus placebo for 4 months; GII-HRT plus MT 2.5mg/day for 4 months; GIII-HRT plus placebo for 2 months and then replaced with HRT plus MT 2.5mg/day for 2 months; GIV-HRT plus MT 2.5mg/day and then replaced with HRT plus placebo for 2 months. Blood was collected at baseline, after 2 months (T1) and 4 months (T2) of treatment for hormone determinations of estradiol, FSH, total and free testosterone, GOT, GPT, glucose, total and fractions of cholesterol and triglycerides. All participants answered clinical questions and a validated questionnaire of modified McCoy's sex scale.
                The association of HRT with MT 2.5mg/day did not significantly change liver enzymes or increase cardiovascular risk factors. The patients of GII, GIIII and GIV when using MT presented amelioration of sex symptoms, mainly satisfaction and desire (p<0.01); however, GIII at T1 (1.3+/-0.3) presented similar problem score results as compared to GIII at T2 (1.5+/-0.6).
                All data suggest that combined HRT-androgen therapy may be beneficial for postmenopausal women receiving HRT who continue to complain of sexual difficulties or for postmenopausal women with sexual complaints who are not undergoing estrogen therapy. Most previous studies designed to evaluate the efficacy of hormone replacement therapy (HRT) have been carried out in Europe, North America and Australia, involving Caucasian women for 6 months or less.
                To evaluate the 12-month effects of two different HRT regimens on postmenopausal symptoms of Middle-Eastern women.
                Hundred healthy Libyan women with postmenopausal symptoms, 12 months or more since their last menstrual period, were enrolled in a 12-month prospective study. Participants were randomly prescribed one of the two formulations, 50 in each group. These regimens were a continuous regimen of tibolone 2.5 mg oral tablets and a continuous regimen of 17beta-oestradiol sequentially combined with dydrogesterone (2/10 mg) oral tablets. The presence and severity of short- and intermediate-term symptoms were reported at 0, 3, 6 and 12 months of treatment. Observed symptoms were hot flushes, night sweating, palpitations, insomnia, depression, nervousness, loss of memory, vaginal dryness, loss of libido and joint pain.
                Forty-nine women (98%) in each group completed the 12-month study period. Participants, in the two groups, experienced a significant improvement within the first 3 months of treatment. The observed symptoms were completely relived by the sixth month without any significant difference between the two groups. Improvements were sustained over the 12-month period of the study. HRT users showed their acceptance to the two regimens.
                Tibolone and 17beta-oestradiol/dydrogesterone oral tablets were effective and safe to treat short- and intermediate-term symptoms in Middle-Eastern postmenopausal women, within 6 months, and with no significant differences between the groups. Thus, the use of HRT to relieve menopausal symptoms is highly recommended, at least in this region. The goal of this study was to investigate the effects of hormone replacement therapy (HRT) and tibolone on the sexuality and quality of life of Taiwanese postmenopausal women.
                Forty-eight postmenopausal women were enrolled and prospectively randomized to receive either HRT or tibolone for 3 months. At the end of the 3-month period, quality of life measures were assessed using the Greene Climacteric Scale and attitudes of sexuality were evaluated using the McCoy Sex Scale.
                Based on subjective qualitative scores, tibolone treatment was at least as effective as continuous combined HRT in improving quality of life. It also effectively prevented withdrawal bleeding, which may occur during HRT use. Compared with continuous combined HRT, tibolone treatment was also associated with perceived improvement of sexual performance, including general sexual satisfaction, sexual interest, sexual fantasies, sexual arousal and orgasm, with decreased frequencies of vaginal dryness and painful intercourse.
                The findings of this study indicate that both tibolone and continuous combined HRT have positive effects on the quality of life of Taiwanese postmenopausal women. Sexuality is affected more by tibolone than by HRT. To compare the effects of tibolone with those of conventional hormone replacement therapy on climacteric symptoms and sexual function in postmenopausal women.
                In a randomized, controlled trial, 140 postmenopausal women were allocated into three groups. Of the subjects included, 47 women received 2.5 mg tibolone + one Cal+D tablet (500 mg calcium and 200 IU vitamin D) daily; 46 women received 0.625 mg conjugated equine estrogen + 2.5 mg medroxyprogesterone (CEE/MPA) + one Cal+D tablet daily; and 47 women received only one Cal+D tablet as the control group. The Greene Climacteric Scale (GCS) questionnaire was used to detect the efficacy of treatment on climacteric symptoms. Rosen's Female Sexual Function Index (FSFI) was used for sexual function evaluation. Sex hormone binding globulin (SHBG), free estradiol index (FEI) and free testosterone index (FTI) were measured before and after treatment. The women were followed up for 6 months
                After treatment, all subscores in the GCS improved in the tibolone and CEE/MPA groups (p < 0.01), except the sexual subscore in the CEE/MPA group, compared with baseline. There were significant differences in the FSFI in the tibolone and CEE/MPA groups in comparison to the control group after treatment. Tibolone, in comparison to CEE/MPA, significantly lowered SHBG levels and increased the FTI and FEI and improved the desire, arousal and orgasm sexual domains of the FSFI (p < 0.001).
                Tibolone may be an alternative to conventional hormone replacement therapy in the treatment of climacteric symptoms and sexual dysfunction in postmenopausal women. To compare compliance, symptom control, bleeding patterns, lipid and biochemical changes in postmenopausal women treated with three regimens of HRT.
                In a prospective, randomised, group comparative study, with 165 patients, the effects on the aforementioned parameters, as well as treatment compliance and side effects were studied with oral tibolone 2.5 mg per day, with cyclic combined regimen of transdermal oestrogen and progestogen (transdermal patch of 17beta-oestradiol 50 microg/day during 14 days and transdermal patch of 17beta-oestradiol 50 microg/day plus 0.25 mg/day NETA during the following 14 days), and with intermittent progesterone regimen (transdermal 17beta-oestradiol 50 microg/day and oral micronised natural progesterone 200 mg twice a week). Statistical analysis was carried out using the Fisher-test, analysis of the variance (ANOVA) and the Bouferoni test.
                Ten women dropped out of the tibolone group, 11 dropped out of the intermittent dosing group and 21 dropped out of the cyclid combined group. Irregular bleeding occurred at more rates in the cyclid combined group. Similar reductions in climacteric symptoms were found in the three groups. No differences were observed with respect to biochemical analysis.
                Efficacy and safety of the three treatment regimens being comparable, but the patients in our study preferred those that did not produce bleeding episodes. To compare relief of vasomotor symptoms, changes in lipoproteins, and bleeding patterns in postmenopausal women receiving either continuous combined hormone replacement therapy (HRT) of estradiol valerate and norethisterone or tibolone 2.5 mg/day.
                In a multicenter, randomized, open-label study, 235 postmenopausal women received one of the above-mentioned treatments. Fasting lipoproteins were measured at baseline and at 3, 6, and 12 months. At each visit, participants completed Greene climacteric questionnaires and recorded any bleeding episodes. Data are presented as mean +/- standard deviation if normally distributed, median and interquartile range if non-normally distributed, or as frequency count. For menopausal symptoms and diary card data, the differences were tested by Wilcoxon rank-sum test.
                One hundred sixteen women received continuous combined HRT and 119 women received tibolone; 72 and 76 women, respectively, completed 12 months of therapy. Both treatments effectively relieved vasomotor symptoms and reduced serum total cholesterol. Continuous combined HRT, but not tibolone, significantly reduced low-density lipoprotein levels. Both treatments reduced high-density lipoprotein levels, but the effect was more profound with tibolone. The initial bleeding score was higher for women taking continuous combined HRT; however, by the end of the study, the percentages of amenorrheal women were comparable. Endometrial histology was similar for both treatments at the end of the study, although two cases of proliferative endometrium were found in the tibolone group.
                Estradiol valerate-norethisterone continuous combined HRT controls symptoms and is associated with a safe lipid profile. Tibolone has been shown to alleviate climacteric symptoms. This study was designed to compare the effect of tibolone (Livial, 2.5 mg daily) on different climacteric complaints and its impact on the endometrium, determined by vaginal ultrasound, with that of conjugated estrogens (Premarin, 0.625 mg daily) continuously for 6 months in combination with the progestogen medrogestone (Colpron, 2 x 5 mg daily for 12 days each month).
                One hundred and twenty-nine postmenopausal women were recruited and the severity of climacteric symptoms as well as endometrial thickness were recorded at the pre-trial examination and after 1, 3, and 6 months.
                With the exception of vertigo, mood depression, mood disorder, loss of libido, and dryness of skin, where tibolone was found to be more effective than conjugated estrogens/medrogestone, climacteric symptoms improved significantly in both groups over the 6-month study period. Endometrial thickness did not increase significantly in the tibolone group, whereas in the conjugated estrogens/medrogestone group there was a highly significant increase after 1 month and still a trend towards significance after 6 months. Recurrence of vaginal bleeding occurred significantly less frequently in the tibolone group than in the comparison group.
                Tibolone seems to offer a complete treatment of the climacteric complaints whilst avoiding some of the problems associated with classical hormone replacement therapy.
HT treatment with estrogens alone or in combination with progestogens was associated with a small to moderate improvement in sexual function, particularly in pain, when used in women with menopausal symptoms or in early postmenopause (within five years of amenorrhoea), but not in unselected postmenopausal women. Evidence regarding other HTs (synthetic steroids and SERMs) is of low quality and we are uncertain of their effect on sexual function. The current evidence does not suggest an important effect of tibolone or of SERMs alone or combined with estrogens on sexual function. More studies evaluating the effect of synthetic steroids, SERMS and the association of SERM + estrogens would improve the quality of the evidence for the effect of these treatments on sexual function in peri and postmenopausal women. Future studies should also evaluate the effect of HT solely among women with sexual complaints.
