Efficacy of single and double platelet-rich plasma treatment for diminished ovarian reserve.

OBJECTIVES

Platelet-rich plasma (PRP) treatment has been reported to improve ovarian function in women, but the relationship between the dose and frequency of PRP treatment and its therapeutic effect remains unclear. This study aims to evaluate the efficacy of single and double PRP treatments for diminished ovarian reserve (DOR).

METHODS

A total of 65 patients treated at the Reproductive Center of Xiangtan Central Hospital from September 2020 to October 2022 were randomly divided into 4 groups: A single PRP treatment group (21 patients, PRP treatment once), a double PRP treatment group (15 patients, PRP treatment twice), a blank control group (15 patients), and an artificial cycle control group (14 patients, treated with estrogen and progesterone). The differences in baseline follicle-stimulating hormone (FSH), antral follicle count (AFC), ovarian volume, number of oocytes retrieved, number of good quality embryos, and pregnancy outcomes before and after treatment were compared among the 4 groups.

RESULTS

Compared to before treatment, both single and double PRP treatment groups showed a significant reduction in FSH, and an increase in AFC, ovarian volume, numbers of oocytes retrieved, and number of MII oocytes (all P<0.05). Compared to the blank control group, the single and double PRP groups showed a decrease in FSH, with an increase in AFC, number of oocytes retrieved, and number of MII oocytes (all P<0.05). The rates of good quality embryos, clinical pregnancy rate, and live birth rate in the single and double PRP groups were higher than those in the blank control group and artificial cycle control groups, but the differences were not statistically significant (all P>0.05). Compared to the single PRP treatment group, the double PRP group had lower FSH and higher AFC, but the differences were not statistically significant (both P>0.05).

CONCLUSIONS

Both single and double PRP ovarian injections can effectively improve ovarian reserve function in DOR patients and enhance ovarian response. Compared to single PRP ovarian injection, double PRP ovarian injection shows a trend of better improvement in ovarian reserve function.
