Abstract Objective To investigate the effect of highly purified human menopausal gonadotropin (HP-hMG) on in vitro fertilization-embryo transfer in patients with diminished ovarian reserve (DOR) at different ages. Methods A total of 133 DOR patients from Handan Central Hospital of Hebei Province from July 2015 to December 2019 were selected, and they were divided into recombinant follicle stimulating hormone group (group A, 67 cases) and HP-hMG group (group B, 66 cases) according to treatment regimen; the two groups were further divided according to age (<35 years or ≥35 years), the ovarian response and pregnancy outcomes of the two groups at different ages were compared. Results Patients aged <35 years old: the amount of gonadotropin (Gn) in group B was higher than that in group A, and estrogen (E2) level on trigger day was lower than that in group A, with statistical significances (P < 0.05). There were no significant differences in cumulative pregnancy rate and cumulative live birth rate between two groups (P > 0.05). Patients aged ≥35 year old: the amount of Gn and top quality embryo rate in group B were higher than those in group A, E2 level on trigger day and egg number obtained were lower than those in group A, with statistical significances (P < 0.05). There were no significant differences in cumulative pregnancy rate and cumulative live birth rate between two groups (P > 0.05). Conclusion HP-hMG can significantly improve top quality embryo rate of DOR patients ≥35 years old.
