Brief Summary

The primary objective is to investigate the efficacy, defined as an increase in oocyte numbers upon ovarian stimulation, and safety of a single intra-ovarian PRP injection vs. saline solution (NaCl) injection (Placebo) transvaginally or laparoscopically for follicular activation in patients with child wish and with low ovarian reserve/expected poor ovarian response planning to undergo IVF or ICSI using own eggs. Pain score as numerical rating score and validated quality of life questionnaire will be requested after the procedure. Longterm follow-up of all participants will be performed 1, 2 and 5 years after end of study.

Detailed Description

Age-related infertility and premature loss of ovarian reserve has become a major challenge for ART professionals as the the average age at first child wish has dramatically increased over time. Under physiological circumstances, most follicles in the human ovary remain dormant throughout the female life span and eventually become atretic, however, histological samples reveal that the follicular pool in the ovary is completely exhausted only as late as the early 70ies and that the ovary holds oogonial stem cells, which may have the ability to differentiate into functional follicles. The pressing problem for reproductive medicine is therefore the question how to reactivate some of the putative ovarian 'reproductive reserve' in those women with premature follicular depletion or those who wish to become pregnant at advanced age.

Platelet rich plasma (PRP) is a blood-derived product, characterized by high concentrations of growth factors and chemokines. PRP is produced by centrifuging a small quantity of the patient's own blood and extracting the active, platelet-rich fraction. The platelet-rich fraction is applied to the human body typically by injection. PRP is used for therapeutic purposes in different medical areas ranging from orthopedics to plastic surgery, for its putative ability to stimulate and facilitate cell proliferation and thereby tissue differentiation and regeneration.

In the context of reproductive medicine, PRP has been proposed to increase pregnancy rates after uterine flushing in women with recurrent implantation failure or thin endometrium. Intra-ovarian injection of PRP has been proposed to activate dormant ovarian follicles pre IVF-treatment in cases of idiopathic low ovarian reserve, premature ovarian insufficiency or ovarian depletion because of advanced maternal age. To date, there is no randomized placebo-controlled trial available that has evaluated intra-ovarian PRP injection in terms of efficacy and safety for premature ovarian failure, and, more specifically, also not in patients with depleted ovarian reserve/poor ovarian response (POR) who constitute a significant proportion of patients undergoing assisted reproduction.

• Intervention Model: PARALLEL
• Primary Study Purpose: TREATMENT
• Blinding Strategy: SINGLE

Study Groups

Autologous intra-ovarian PRP injection

Study group, treated with autologous intra-ovarian PRP injection and undergoing a subsequent fresh ET-IVF/ICSI cycle in the third cycle after intervention

Group Type: EXPERIMENTAL

autologous PRP (platelet rich plasma)

Intervention Type: BIOLOGICAL

The required volume of PRP will be extracted from 60 ml of the patient's peripheral blood. Injecting PRP into the ovaries will be performed likewise to the standard operating procedure of oocyte retrieval. After centrifugation of the whole blood, 5ml PRP will be injected in each ovary intra-medullar and subcortical using a 17-gauge single lumen needle under sedation und under transvaginal ultrasound monitoring.

intra-ovarian saline solution (NaCL) injection

Control group, treated with intra-ovarian NaCl injection and undergoing a subsequent fresh ET-IVF/ICSI cycle in the third cycle after intervention

Group Type: PLACEBO_COMPARATOR

Saline solution (NaCL) Injection

Intervention Type: OTHER

Injecting NaCL into the ovaries will be performed likewise to the standard operating procedure of oocyte retrieval. NaCL will be injected in each ovary intra-medullar and subcortical using a 17-gauge single lumen needle under sedation und under transvaginal ultrasound monitoring.
