Abstract

OBJECTIVE:

To assess the association of rs13405728 polymorphism of luteinizing hormone receptor (LHR) gene with slow ovarian response during assisted reproductive technology (ART).

METHODS:

Two hundred and thirty-six women were enrolled and grouped according to their genotypes. The rs13405728 polymorphism was genotyped by DNA sequencing.

RESULTS:

No signifiicant difference was found in antral follicle count and anti-Mullerian hormone between the three genotypes (P>0.05). The incidence of slow response in genotype GG was lower than in the other two genotypes (P<0.05). There was no significant difference in the amount of follicle stimulating hormone required, the number of follicles ≥14 mm on human chorionic gonadotrophin day, oocytes, mature oocytes, available embryos, and the clinical pregnancy rate among the three genotypes (P>0.05). There was an independent correlation between slow ovarian response with the genotypes of rs13405728, the initial dose of gonadotropin, and the dose of luteinizing hormone required (P<0.05).

CONCLUSION:

Rs13405728 of the LHR gene may be associated with slow ovarian response in ART. Various mechanisms may be involved in the poor response and slow response.
