BACKGROUND The goal of this study was to evaluate the association of SCARB1 single nucleotide polymorphisms (SNPs) and fertility outcomes in women undergoing IVF. METHODS Between November 2007 and March 2010, granulosa cells and follicular fluid were collected from women undergoing IVF. Five SCARB1 SNPs were sequenced and progesterone levels were measured in the follicular fluid. Fertility measurements were defined as the presence of gestational sac(s) and fetal heartbeat(s). RESULTS The study group consisted of 274 women (mean age of 36.4 ± 4.6 years). The racial/ethnic composition was 55% Caucasian (n = 152), 25% African-American (n = 68), 12% Asian (n = 34), 5% Hispanic, (n = 14) and 2% other (n = 6). There was a significant difference in the genotype frequencies of the SCARB1 SNPs across the groups. Subjects who were homozygous for the minor allele in the rs5888 SNP had higher follicular progesterone levels than those who were homozygous for the major allele (P = 0.03). In the Caucasian group, carriers of the minor A allele of the rs4238001 SNP had lower follicular progesterone levels compared with homozygous carriers of the major G allele (P = 0.04). In this group, follicular progesterone levels were highly predictive of the rs4238001 SNP (P = 0.03). In the entire cohort, minor allele carriers of rs4238001 did not have any viable fetuses at Day 42 following embryo transfers (P = 0.04). In the African-American group in particular, there was also an association between rs10846744 and gestational sac(s) (P = 0.006), and fetal heartbeat(s) (P = 0.005). CONCLUSIONS In part, SCARB1 rs4238001 and rs10846744 SNPs may contribute to human female infertility
