Improving the Reproductive Outcome of Poor Quality Ova by Injection of Autologous Somatic Mitochondria

Phase 1
Withdrawn
Conditions
Low Ovarian Reserve
Poor Quality Oocytes
Interventions
Procedure: Injection of an autologous mitochondria to the oocyte.
Registration Number
NCT01631578
Lead Sponsor
Hadassah Medical Organization
Brief Summary

A prospective randomized controlled trial (RCT) to determine the effect of injecting an autologous somatic mitochondria concentrate, together with the spermatozoon during ICSI, into oocytes of older and or poor prognosis in vitro fertilization (IVF) patients.

Detailed Description

Maternal age at first delivery constantly rises in developed countries. Oocyte quality decreases with advanced age, thus the rate of age-related infertility continuously increases. Presently oocyte donation is the only prompt solution for this widespread problem. Deterioration of mitochondrial function was suggested as one of the explanations for the age-related deterioration of oocyte quality. The supplementation of the ageing oocyte with autologous mitochondria from dividing somatic cells can be a possible solution for energetic enrichment, without introducing foreign mtDNA.

We established a non-hazardous clinical grade system to prepare functional autologous mitochondria concentrate from the granulosa cells aspirated during oocyte pick up. The mitochondrial preparation was examined and found to be non-toxic. The activity of the respiratory chain was constant and unaffected by age or ovarian response. Moreover, the mtDNA in the mitochondrial preparation was found to be intact in all samples examined, including those from older and low responding patients.

Primary Outcome Measures
NameTimeMethod
The rate pace and quality of the early embryonic developmentup to 6 days

The rate (the proportion of fertilized oocytes developing into embryos), pace of cleavage, and quality (morphological) of the early embryonic development will be assessed during the next 1-6 days (case specific).

Oocyte fertilization rateone day

Fertilization rate is assessed the day following oocyte retrieval.

Secondary Outcome Measures
NameTimeMethod
Clinical pregnancywithin 2 months
