Summary

In this study, patients with infertility treated with IVF at the Center of Reproductive Medicine in Linköping, Sweden, will receive recipes and food according to Nordic dietary guidelines. The purpose is to investigate whether a short diet intervention is sufficient to improve sperm quality and shift the small non-coding RNA profile. In our previous study sperm showed rapid response to diet.

Detailed description

This study is a randomized controlled trial recruiting males seeking IVF treatment with their female partner at the Center for Reproductive Medicine in Linkoping, Sweden. Men will be randomized to a control group or diet intervention group. The intervention group will receive groceries with planned recipes during the hormonal treatment period for the woman (11-14 days) before IVF. The meal plan will be according to the Nordic dietary guidelines and individualized to match total energy expenditure. The male partner must accept to participate in the diet intervention in order to be included and the female partner can choose to participate in the diet intervention but it is optional. Sperm samples will be collected before the start of hormonal treatment and on ovum pick-up day. Weight will be measured before and after the intervention. Sperm samples will be processed as standard practice at the fertility clinic. Sperm samples will be used for molecular analysis, such as small RNA sequencing.
