Also the use of folic acid supplements, folate status and the frequency of different gene variations were studied in women undergoing infertility treatment and fertile women.DESIGN: Observational study.SETTING: University hospital.POPULATION: Women undergoing infertility treatment and healthy, fertile, non-pregnant women.METHODS: A questionnaire was used to assess general background data and use of dietary supplements. Blood samples were taken to determine plasma folate and homocysteine levels, and for genomic DNA extraction. A comparison of four studies was performed to assess pregnancy outcome in relation to MTHFR 677 TT vs. CC, and 1298 CC vs. AA polymorphisms.MAIN OUTCOME MEASURES: Folic acid supplement intake, and plasma folate, homocysteine and genomic assays.RESULTS: Women in the infertility group used significantly more folic acid supplements and had better folate status than fertile women, but pregnancy outcome after fertility treatment was not dependent on folic acid intake, folate status or MTHFR gene variations.CONCLUSION: High folic acid intakes and MTHFR gene variations seem not associated with helping women to achieve pregnancy during or after fertility treatment.
