Abstract
Background
One determining factor of a successful in vitro fertilization (IVF) cycle
is embryo quality. The aim of the present study was to evaluate associations of embryo
quality and reserve markers like age, FSH and AMH.
Materials and Methods
In this prospective study, 120 infertile women, aged 21-44
years, undergoing routine exploration during an unstimulated cycle preceding assisted
reproductive technology (ART) at our center were studied prospectively, from February
2011 to December 2014. Descriptive parameters and patient characteristics were reported
as mean (SD) or median (range) depending on the distribution. Student’s t test was performed for continuous variables, Wilcoxon and Pearson’s Test were used for not distributed variables and Fisher’s Test was performed for categorical variables. P<0.05 was
considered statistically significant.
Results
Overall, at the time of investigation, patients had a mean age of 33.03 ± 4.15
years old. On cycle day three, serum anti-Mullerian hormone (AMH) level was 3.50
± 1.54 ng/mL, serum follicle-stimulating hormone (FSH) level was 6.29 ± 1.53 mUI/
mL, at baseline, women had 16.57 ± 7.0 antral follicles. The mean of collected oocytes
was 11.80 ± 5.25, embryo I+II was 2.46 ± 2.11. A greater number of embryos I+II was
observed in young patients. By evaluating 120 patients, a significant relationship was
observed between age and FSH (r=0.24, P=0.01), age with AMH (r=-0.22, P=0.02), age
with collected oocytes (r=-0.23, P=0.03) and age with embryo I+II (r=-0.22, P=0.03).
A significant relationship was also observed between antral follicle count (AFC) and
AMH (r=0.29, P=0.01), AFC and the number of transferred embryo (r=-0.18, P=0.03),
AFC and total dose of the drugs (r=-0.23, P=0.03). Significant relationship of FSH with
total dose of drugs (r=0.19, P=0.02) was also observed. In addition, we determined
significant relationships between AMH and the number of collected oocytes (r=0.38,
P=0.01), AMH and the number of metaphase II oocytes (r= 0.35, P=0.01), AMH and
the number of embryo (r=0.19, P=0.04) as well as AMH and total dose of the drugs
(r=-0.25, P=0.01).
Conclusion
Commonly used clinical markers of ovarian reserve are reflection of the
ovarian reserve, while the outcome measurements of ART and age are the best predictors
of embryo quality.
