    Notes: Objective To compare continuous combined hormone replacement therapy (ccHRT) and raloxifene with respect to compliance and quality of life, which were predefined secondary endpoints of a large, prospective study designed to investigate the uterine effects of both treatments.Design Double-blind, randomised controlled trial of six-month duration.Setting One hundred and twenty-nine gynaecology hospital departments, clinics or practices specialised in women's healthcare, located in Europe, South Africa and Israel.Population Healthy postmenopausal women (n= 1008).Main outcome measures Changes in quality of life using the Women's Health Questionnaire (WHQ) and compliance using a compliance questionnaire and pill count. Adverse event and early discontinuation rates and satisfaction with treatment using a visual analogue scale (VAS).Results Women taking raloxifene reported greater satisfaction with their treatment as assessed on the VAS (P= 0.004),and a lower proportion, as compared with ccHRT, reported being worried by the treatment (9.6%vs 20.2%, P 〈 0.01). Women taking ccHRT reported greater deterioration in scores from the WHQ for depressed mood and menstrual symptoms than those taking raloxifene (P 〈 0.01). For memory, vasomotor symptoms and sexual behaviour, the ccHRT group reported significantly greater mean improvements (P 〈 0.05). Over half (58.8%) of those taking raloxifene noticed no effect, 37.7% felt better and 3.4% felt worse as measured using the compliance questionnaire. Fifty percent of the women taking ccHRT felt better, 37.8% noticed no effect but over 10% felt worse. More women on raloxifene (94.6%) than on ccHRT (85.9%) reported that they were taking their double-blinded medication regularly (P 〈 0.01).Conclusions A lower rate of adverse event-related discontinuations, the lack of negative effects on quality of life and a smaller proportion of women being worried by the drug treatment were associated with higher treatment satisfaction and better compliance in postmenopausal women taking ccHRT or raloxifene.

    Notes: Abstract Purpose: Our purpose was to demonstrate the feasibility of the routine aspiration of supernumerary follicles in infertile patients with imminent polyovulation after ovulation induction with gonadotropins and to examine its effect on the frequency of cycle cancellation and on the (multiple) pregnancy rate. Methods: The data on 796 treatment cycles, performed between 1989 and 1996 on 410 infertile couples, were analyzed retrospectively. From October 1992, whenever necessary, supernumerary ovarian follicles were selectively aspirated transvaginally under ultrasound guidance to prevent the ovulation of more than three follicles. Thereafter, intrauterine insemination was performed. Results: After the adoption of transvaginal ultrasound-guided aspiration of supernumerary follicles into the treatment protocol in October 1992, the number of canceled cycles (P 〈 0.0001) and the multiple pregnancy rate (P 〈 0.01) were significantly reduced compared to those previously. The overall pregnancy rate remained stable. No ovarian hyperstimulation syndrome requiring hospitalization was noted, and no complications resulting from the follicle aspiration were registered. Conclusions: Transvaginal ultrasound-guided aspiration of supernumerary ovarian follicles increases both the efficacy and the safety of ovulation induction with gonadotropins. Because of the limited equipment required, this method represents an alternative for conversion of overstimulated cycles to more costly alternatives such as in vitro fertilization.

    Notes: Abstract Purpose: Reactive oxygen species (ROS) including H2O2 produced by spermatozoa have been suggested, on one hand, to be associated with idiopathic male infertility and, on the other hand, to stimulate certain sperm function leading to fertilization. The influence of ROS on fertilization was investigated in 75 IVF patients by correlating fertilization rates with the production of ROS and the H2O2-scavenging activity of swim-up spermatozoa prepared in parallel with the IVF samples. Results: Low rates of ROS production by the swim-up sperm was detected by the luminol-dependent chemiluminescence assay. They were not correlated with fertilization rates. The hydrogen peroxide scavenging capacity of these spermatozoa, measured as the removal of exogenous H2O2 assayed spectrophotometrically, decreased stepwise in groups of patients achieving higher fertilization rates, suggesting a positive effect of this ROS on fertilization. An alternative explanation of this correlation is plausible in view of the association of both high scavenging activities and poor fertilization rates with poor sperm morphology. Conclusions: ROS produced by spermatozoa selected by swim-up plays no negative, if not a positive, role in fertilization.
