Abstract

Dietary intake of omega-3 polyunsaturated fats (PUFAs) may be associated with successful assisted reproductive techniques (ART). However, heterogeneous studies were conducted and opposing results were obtained. This systematic review aims to summarize the evidence on the effect of omega-3 dietary intake on oocyte and embryo quality for a positive ART outcome. The PRISMA 2020 statement was followed and the review protocol was registered with PROSPERO (CRD42021283881). Inclusion and exclusion criteria were: eligible studies examined women undergoing ART cycles whose diet was evaluated for omega-3 intake or experienced an increase in omega-3 compared with women who followed in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) but did not increase the omega-3 intake before the cycle. 5,412 records were identified and five studies were included in the analysis. Two studies focused on sub-fertile or infertile women specifically, yet all women in all studies went through IVF/ICSI procedures. All five studies demonstrated how omega-3 FAs may be beneficial by increasing the positive rate of ART outcomes and embryo quality evaluated according to morphology and morphokinetic parameters. More research focusing on comparable and/or equal outcomes is required to strengthen supporting evidence with the aim to provide valid recommendations for women seeking a pregnancy.
