Continuous use of oral contraceptives: an overview of effects and side-effects.

OBJECTIVE: To describe the effects and side-effects of the continuous use of oral contraceptives. DESIGN: A review of articles concerning oral contraceptives taken continuously or in cycles with hormones taken for more than 21 days per cycle. METHODS: We searched publications in PubMed and Embase. Randomized controlled trials were selected if possible, otherwise case-control studies or cohort studies with controls were chosen. A level of evidence as described by the Centre for Evidence Based Medicine (Oxford University, Oxford, UK) was assigned to all selected studies. MAIN OUTCOME MEASURES: Clinical and paraclinical effects and side-effects of oral contraceptives administered continuously. RESULTS: The studies suggest that the endometrium is inactive during continuous use of oral contraceptives and the risk of endometrial hyperplasia is not increased. Numbers of bleeding days are halved with continuous use; however, spotting and irregular bleeding are more often seen in the beginning of use, decreasing with time. Hemostatic parameters and serum lipid and carbohydrate profiles in continuous and conventional users do not differ. Menstrual cycle-related symptoms are relieved better by continuous treatment. After surgery for endometriosis, the effect of continuously used oral contraceptives on the risk of recurrence of pain has been found to be less than that of gonadotropin-releasing hormone (GnRH) analogues, but better than the rate seen during conventional cyclic use. CONCLUSION: Oral contraceptives taken continuously or in long cycles seem to offer benefits with regard to menstrual symptoms and the recurrence of symptoms related to endometriosis. Long-term studies, comprising large groups of women, are lacking.

Lower urinary tract symptoms after total and subtotal hysterectomy: results of a randomized controlled trial.

The aim of this Danish multicenter trial was to compare the proportion of women with lower urinary tract symptoms after total abdominal hysterectomy (TAH) and subtotal abdominal hysterectomy (SAH) for benign uterine disorders. A total of 319 women were randomized to TAH (n = 158) or SAH (n = 161). Women were followed up for 1 year by strict data collection procedures, including postal questionnaires. Results were analyzed by intention-to-treat analyses. Urinary incontinence was found less often among TAH women than among SAH women. This was due to a larger reduction of the number of women with stress and urinary incontinence in the TAH group. No other differences were found between the two operation methods. The number of women with urinary incontinence and frequency was reduced from study entry for follow-up, while double/triple voiding was increased. Incontinent women had significantly lower quality of life scores than continent women

Sexuality after total vs. subtotal hysterectomy.

BACKGROUND: The effect of hysterectomy on sexuality is not fully elucidated and until recently total and subtotal hysterectomies have only been compared in observational studies. AIMS: To compare total abdominal hysterectomy (TAH) to subtotal abdominal hysterectomy (SAH) regarding effects on sexuality. METHODS: In a Danish multicenter trial 319 women were randomized to TAH (n = 158) or SAH (n = 161); 185 women had self-selected TAH (n = 80) or SAH (n = 105) in a simultaneously conducted observational study. Women were followed for 1 year by strict data collection procedures, including postal questionnaires. Results were analyzed by intention to treat (ITT) analyses. RESULTS: No significant differences were observed between TAH and SAH at 1-year follow-up in both the randomized trial and the observational study regarding women's desire for sex, frequency of intercourse, frequency of orgasm, quality of orgasm, localization of orgasm, satisfaction with sexual life, and dyspareunia. None of these sexual variables changed significantly from entry to the 1-year follow-up, apart from dyspareunia, which was significantly (p = 0.009) reduced in both intervention groups. Significant (p < 0.05) predictors for satisfaction with sexual life after hysterectomy were the preoperative satisfaction with sexual life [odds ratio (OR) 32, 95% confidence interval (CI) 10-125], good relationship with partner (OR 50, 95% CI 9-354), physical well-being (OR 0.30, 95% CI 0.09-0.88) and hormone replacement therapy (OR 0.23, 95% CI 0.06-0.78). CONCLUSIONS: Both TAH and SAH significantly reduce dyspareunia without having a negative effect on sexual function. The shift toward SAH seems unwarranted.
