The detrimental effect of overweight and obesity on fecundity has been well documented.
The investigators wish to investigate the intervention program for weight loss before fertility treatment.
Subsequently to gain knowledge on the effect of overweight/obesity and weight loss on the vaginal microbiome, on DNA damage on sperm cells, on the occurrence of endocrine disruptors in the endometrium, and on the gene expression in the endometrium.
Purpose and aim of the study The Fertility Clinic at Zealand University Hospital wishes to introduce a new care concept: 'Healthy Parents - Healthy Children´ with the purpose of changing the behaviours of infertile men and women towards a healthier life style now and for future generations.
The Zealand Region includes areas of significant deprivation compared to Copenhagen and has a higher prevalence of obesity and poor diet.
These inequalities generate socio-demographic and long-term health challenges, decrease the chance of becoming pregnant and increase risk of life style related diseases for parents and their offspring in the long term.
The waiting time before fertility treatment (12 months in the region) represents a unique window of opportunity to encourage long-term life style changes. The aforementioned reasons initiated the planned Preconception Clinic 'Healthy Parents - Healthy Children´.
The Preconception Clinic utilises waiting list time to optimise parental health prior to conception. We will provide weight loss interventions aimed at helping the patients to a healthier lifestyle, an increased chance of conception and a decreased risk of life style diseases for themselves and their future offspring.
Purpose of study:
Patient weight loss of at least 10% at the end of intervention and at annular follow up until 5 years.
Study population: Sub-fertile population referred to the Fertility Clinic Region Zealand due to infertility.
Inclusion criteria:
20 women and 20 men with a BMI>30, age 18-40 years.
Exclusion criteria:
Inability to understand the written and oral information.
Baseline and end of intervention-sampling:
Intervention: Weight reduction through life style changes in diet and exercise by the following means:
Primary endpoint: Weight loss of at least 10%.
Anticipated impact The aim of this study is to find a feasible intervention that can change adverse life styles in a preconception setting. Elements from the weight loss intervention can be incorporated to the broader community, for instance as Preconception weight loss packages in the local municipalities, aimed at optimizing health before conception in the general fertile population.
