Figure 3: MtDNA copy number for preimplantation embryos.

(a) Mean (±SEM) mtDNA copy number for BCB⁺ IVF; (b) BCB⁺ ICSI; (c) BCB⁻ ICSI and (d)BCB⁻ mICSI-derived embryos determined by real time PCR (n = 5–10). (e) Mean (±SEM) mtDNA copy for each stage of development for embryos generated by IVF, ICSI and mICSI from BCB⁺ and BCB⁻ oocytes.
