Figure 4From: Increased GDF9 and BMP15 mRNA levels in cumulus granulosa cells correlate with oocyte maturation, fertilization, and embryo quality in humansComparison of OSFs mRNA levels between the groups with and without pregnancy. (a) The relative expression of GDF9 mRNA in the pregnancy group and the nonpregnancy group. (b) The relative expression of BMP15 mRNA in the pregnancy group and the nonpregnancy group. *P<0.05.Back to article page
