Evidence check: ApoB in the context of Fruchtbarkeit

ApoB (Apolipoprotein B) reflects the number of atherogenic lipoprotein particles and is primarily a cardiovascular risk marker. In the context of fertility, observational studies suggest that elevated ApoB – especially in women with PCOS or metabolic syndrome – may be linked to impaired ovarian function, disrupted folliculogenesis, and poorer IVF outcomes. However, the evidence is mostly observational and not strong enough to establish ApoB as a standalone fertility biomarker. The MyBody-X Fertility Check does not include ApoB; it focuses on hormones like AMH, FSH, estradiol, progesterone, and prolactin. An elevated ApoB level should be interpreted as part of a broader cardiovascular risk profile, not as a direct fertility indicator. The evidence base is moderate but insufficient for clinical fertility recommendations. For individuals with metabolic concerns and a desire to conceive, a lipid panel including ApoB may be considered – but only under medical guidance.
