Abstract
Background: High
dietary fat consumption may alter oocyte development and embryonic
development. This prospective study was conducted to determine the
relation between dietary fat consumption level, its food sources and the
assisted reproduction parameters. Methods: A prospective study was
conducted on 240 infertile women.
In assisted reproduction treatment cycle, fat consumption and major
food sources over the previous three months were identified. The number
of retrieved oocytes, metaphase II stage oocytes numbers, fertilization
rate, embryo quality and clinical pregnancy rate were also determined.
The data were analyzed using multiple regression, binary logistic
regression, chi-square and t-test. The p-value of less than 0.05 was
considered significant. Results: Total fat intake adjusted for age, body
mass index, physical activity and etiology of infertility was
positively associated with the number of retrieved oocytes and inversely
associated with the high embryo quality rate. An inverse association
was observed between sausage and turkey ham intake and the number of
retrieved oocytes. Also, oil intake level had an inverse association
with good cleavage rate. Conclusion: The results revealed that higher
levels of fat consumption tend to increase the number of retrieved
oocytes and were adversely related to embryonic development. Among food
sources of fat, vegetable oil, sausage and turkey ham intake may
adversely affect assisted reproduction parameters. © 2014, Avicenna Research Institute. All rights reserved.
