Normal fertilisation rates and serum 25-OHD levels among couples undergoing in-vitro fertilisation: a prospective cohort study.

ABSTRACT: BACKGROUND:The aim of this study was to explore the correlation between serum vitamin D levels in couples undergoing in-vitro fertilisation (IVF) and normal fertilisation process. METHODS:Between March 2016 and March 2017, we performed a prospective cohort study at an academic reproductive medicine centre to measure serum 25-hydroxyvitaminD (25-OHD) levels of 1232 couples before controlled ovarian stimulation. Generalized linear regression and binary multivariate logistic regression were employed to assess whether 25-OHD levels in men and women correlated with normal fertilisation rates and low fertilisation rate (LFR). RESULTS:Serum 25-OHD levels in women were classified into three groups: Group A, less than 10%; Group B, between 10 and 90%; and Group C, greater than 90%. Using generalized linear regression, we observed that female 25-OHD levels were related to normal fertilisation rates. Adjusted normal fertilisation rates from Group A to Group C in women were 59.50, 62.72, and 66.13%, respectively (P?=?0.007). After binary logistic regression analysis, for women, compared with Group C, the ORs for LFR were 4.814 in Group A (95% CI, 1.266-18.309, P?=?0.021) and were 3.204 in Group B (95% CI, 0.949-10.812, P?=?0.061). Male 25-OHD levels were not related to the probability of low fertilisation rate (P?>?0.05). CONCLUSIONS:Circulating 25-OHD concentrations in women appear to be associated with normal fertilisation rates and low fertilisation rates in IVF cycles, but not in men. A further randomized controlled trial with vitamin D supplementation is needed to demonstrate whether female vitamin D levels exert an effect on the normal fertilisation process.

Project description:ObjectiveTo evaluate whether acupuncture improves rates of pregnancy and live birth when used as an adjuvant treatment to embryo transfer in women undergoing in vitro fertilisation.DesignSystematic review and meta-analysis.Data sourcesMedline, Cochrane Central, Embase, Chinese Biomedical Database, hand searched abstracts, and reference lists. Review methods Eligible studies were randomised controlled trials that compared needle acupuncture administered within one day of embryo transfer with sham acupuncture or no adjuvant treatment, with reported outcomes of at least one of clinical pregnancy, ongoing pregnancy, or live birth. Two reviewers independently agreed on eligibility; assessed methodological quality; and extracted outcome data. For all trials, investigators contributed additional data not included in the original publication (such as live births). Meta-analyses included all randomised patients.Data synthesisSeven trials with 1366 women undergoing in vitro fertilisation were included in the meta-analyses. There was little clinical heterogeneity. Trials with sham acupuncture and no adjuvant treatment as controls were pooled for the primary analysis. Complementing the embryo transfer process with acupuncture was associated with significant and clinically relevant improvements in clinical pregnancy (odds ratio 1.65, 95% confidence interval 1.27 to 2.14; number needed to treat (NNT) 10 (7 to 17); seven trials), ongoing pregnancy (1.87, 1.40 to 2.49; NNT 9 (6 to 15); five trials), and live birth (1.91, 1.39 to 2.64; NNT 9 (6 to 17); four trials). Because we were unable to obtain outcome data on live births for three of the included trials, the pooled odds ratio for clinical pregnancy more accurately represents the true combined effect from these trials rather than the odds ratio for live birth. The results were robust to sensitivity analyses on study validity variables. A prespecified subgroup analysis restricted to the three trials with the higher rates of clinical pregnancy in the control group, however, suggested a smaller non-significant benefit of acupuncture (odds ratio 1.24, 0.86 to 1.77).ConclusionsCurrent preliminary evidence suggests that acupuncture given with embryo transfer improves rates of pregnancy and live birth among women undergoing in vitro fertilisation.

Project description:INTRODUCTION:Infertility and in vitro fertilisation (IVF; with or without intracytoplasmic sperm injection) result in considerable emotional and financial burden. Increasing evidence suggests that lifestyle factors, including diet, physical activity and personal well-being, are associated with IVF-success rates. Currently, IVF is not routinely combined with a lifestyle programme. The preconception lifestyle (PreLiFe) randomised controlled trial (RCT) assesses the effects of a new mobile PreLiFe programme in couples undergoing IVF. METHODS AND ANALYSIS:A multicentre RCT including 460 heterosexual couples starting IVF in Belgian fertility clinics. IVF couples are randomised between an attention control group or the PreLiFe programme for a period of 12 months or until an ongoing pregnancy is confirmed by ultrasound. The attention control programme includes a mobile application with treatment information (ie, appointments and medication instructions) in addition to standard care. The PreLiFe programme includes a mobile application with the same treatment information in combination with a lifestyle programme. This new lifestyle programme includes tailored advice and skills training on diet, physical activity and mindfulness in combination with text messages and telephone interaction with a healthcare professional trained in motivational interviewing. The primary outcome of this RCT is the cumulative ongoing pregnancy rate within 12 months after randomisation. Secondary outcomes include changes in diet, physical activity, emotional distress, body mass index, waist circumference, quality of life and other reproductive outcomes including IVF discontinuation, clinical pregnancy rate and time to pregnancy. Additionally, partner support and the feasibility (use and acceptability) of the PreLiFe programme will be evaluated in the intervention group. Analysis will be according to intention to treat. ETHICS AND DISSEMINATION:This study has been approved by the Medical Ethical Committee of the Leuven University Hospital (Belgium) and the other recruiting clinics. The findings of this RCT will be disseminated through presentations at international scientific meetings and peer-reviewed publications. TRIAL REGISTRATION NUMBER:NCT03790449; Pre-results.

Project description:PurposeThe purpose of this study was to examine the effects of psychosocial interventions on the mental health, pregnancy rates, and marital function of infertile couples undergoing in vitro fertilization (IVF), as determined through RCT studies.MethodsUsing the electronic databases PubMed, EMBase, Cochrane Library, CINAHL, PsycInfo, and CAJ, a systematic literature search was conducted in July 2015. MeSH terms, key words, and free words such as "infertility," "fertilization in vitro," "psychotherapy," "intervention," "anxiety," "depression," and "marital satisfaction" were used to identify all potential studies. The quality of the studies that were included was assessed using the risk of bias assessment tool developed by the Cochrane Back Review Group. Descriptive analysis was adopted to synthesize the results.ResultsA total of 20 randomized controlled trials were included in this review. There were reports of positive effects on the anxiety levels, pregnancy rates, or marital function of infertile couples in six studies that adopted different psychosocial approaches, including mind body intervention (Eastern body-mind-spirit, Integrative body-mind-spirit, and Mind/body intervention), cognitive behavioral therapy, group psychotherapy, and harp therapy. However, there were methodological or practical issues related to measurement points and attrition rates in these studies. None of these interventions were found to be efficacious in relieving the depression or stress of individuals or couples undergoing IVF treatment. None of the included studies tackled or measured the mental health status of the couples during the most stressful time of waiting for the pregnancy results of their treatment.ConclusionsA complex intervention, based on sound evidence, should be developed targeting both females and males of infertile couples undergoing IVF treatment, particularly during the stressful period of waiting for the results of the pregnancy test result and after failed cycles.
