Abstract

The luteinizing hormone receptor (LHCGR) has a little studied polymorphic 6 bp insertion (rs4539842/insLQ). This study has evaluated the insLQ polymorphism in relation to potential associations with hormonal characteristics of human small antral follicles (hSAFs). In total, 310 hSAFs were collected from 86 women undergoing fertility preservation. Analysis included hormonal profile of 297 follicular fluid (FF) samples and 148 corresponding granulosa cells samples were evaluated by qPCR for selected genes. Significantly reduced and non-detectable mRNA levels of anti-Müllerian hormone receptor II (AMHR2) and LHCGR, respectively, were observed for insLQ/insLQ compared to –/insLQ and the −/− genotypes. Moreover, LHCGR and CYP19a1 together with oestradiol and inhibin-B were significantly increased in –/insLQ compared to the −/− genotype. The homozygous insLQ genotype showed strong significant associations to GC specific genes LHCGR and CYP19a1, which may translate into significant changes in FF hormone profiles and an altered LH signaling.
