Study Details

Study Description

Brief Summary

This study was a prospective randomized controlled trial. Patients with POR who were aged <40 years and underwent IVF/ICSI with assisted ovulation induction at our hospital were enrolled in the study. After randomization using Excel (Microsoft Corporation, Albuquerque, NM, USA), these patients were divided into two groups. Group A was the experimental group, wherein ovarian injections of PRP were administered to the patients, and group B was the control group, wherein no ovarian puncture or injection was used in the patients.

Detailed Description

Poor ovarian response (POR) is a pathological state, wherein the ovaries are insensitive to exogenous gonadotropin (Gn) stimulation; it is often noted older populations with ovarian hypofunction. POR mainly manifests as the development of only few follicles during ovarian stimulation cycles, low peak levels of blood estrogen on human chorionic Gn (HCG) trigger day, high dosage of exogenous Gn, high rates of cycle cancellation, low number of oocytes retrieved, and low rates of clinical pregnancy. The incidence of POR during ovulation induction in assisted reproduction is reported to be approximately 9%-24%. With the increasing age of individuals at marriage and childbearing as well as the reform of the national family planning policy, an increasing number of women of advanced maternal age have resorted to assisted reproductive technology for fertility, resulting in an increased proportion of patients with POR in China. Repeated in-vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) cycles and adverse pregnancy outcomes of patients with POR have undoubtedly resulted in great financial burden and psychological pressure on infertile couples. Therefore, the individualized selection of an appropriate ovulation induction protocol has become a key factor in terms of improving ovarian responsiveness, which can in turn improve ovarian sensitivity to ovulation drugs and increase oocyte quantity and quality when the patient is supplemented with pre-treatment prior to ovulation induction.

The intraperitoneal injection of autologous platelet-rich plasma (PRP) into the ovaries of mice of the cyclophosphamide-induced premature ovarian failure model resulted in an increase in ovarian cortical volume, preantral follicle number, and antral follicle and their corresponding oocyte diameters. This finding suggests that PRP has a positive effect on the tissue repair of damaged ovaries and that it stimulates the growth of various follicles after ovarian damage in animals, is involved in oogenesis, induces an increase in the number of follicles and granulosa cells, and stimulates estrogen secretion. The addition of PRP to in-vitro three-dimensional cultures of follicles increases the viability and growth of human primordial and preantral follicles and produced more beneficial growth factors. The Pantos team pioneered the administration of intra-ovarian injections of PRP to four infertile patients of advanced maternal age with ovarian hypofunction. These patients' ovarian reserves improved, as evidenced by their elevated serum anti-Müllerian hormone (AMH) levels, decreased follicle-stimulating hormone (FSH) levels, and/or increased total antral follicular counts. Then, the patients received IVF treatment, each patient receiving at least one blastocyst for cryopreservation. A recent clinical study used PRP in 19 patients with POR. Two of these patients had spontaneous pregnancies and one had a successful clinical pregnancy. Taken together, this evidence suggests the promising use of PRP in ovarian tissue and the potential of PRP as a novel effective treatment option for patients with POR.

In light of the current situation of POR treatment, the investigators proposed a clinical research project of ovarian injection of autologous PRP for the treatment of POR. The PRP used clinically has been evaluated in well-developed preclinical safety studies and necessary quality control without any ethical controversy. Moreover, PRP does not pose a medical risk and has high safety levels in the treatment of diseases. The goal of our project was to aid in the development of new methods of POR treatment that can meet the urgent fertility needs of patients.

Arms and Interventions

Arm Intervention/Treatment
Experimental: PRP

ovarian injections of PRP were administered to the patients

Biological: PRP
PRP was prepared using double centrifugation of the patient's autologous whole blood, and 400 µL of PRP was injected via vaginal puncture into the ovarian parenchyma.

No Intervention: No ovarian puncture or injection

no ovarian puncture or injection was used in the patients

Outcome Measures

Primary Outcome Measures

  1. number of oocytes retrieved [30 days after PRP injected]

    When at least one dominant follicle reached a diameter of 18 mm or higher, 0.2 mg triptorelin was combined with 1,000 U HCG as the trigger, and ovarian puncture was performed 36 hours later for oocyte retrieval. The number of oocytes retrieved was recorded.
