Does advanced male partner’s age impact live birth rates (LBRs) in IVF treatment when female partner’s age is factored in?
Advanced paternal age is associated with declining sperm parameters, impaired embryo development, compromised pregnancy outcomes, and abnormalities in the offspring in IVF/ICSI cycles. However, data on the interaction between maternal and paternal age on IVF outcomes are very limited and inconsistent. No significant effect of male partner’s age on pregnancy outcomes has been noted in donor oocyte cycles.
Retrospective analysis of all eligible autologous IVF/ICSI cycles with oocyte retrieval and intended fresh embryo transfer (ET) from the UK’s national anonymized registry, published online by the Human Fertilisation and Embryology Authority (HFEA). There were 59 951 cycles that qualified the inclusion criteria in the study period: 1 January 2017 to 31 December 2018.
This is the largest clinical data to support the laboratory evidence of the ability of oocytes from young women to reverse the age-related deterioration of sperm quality. As the ageing oocytes lose this reparatory mechanism, the ageing sperm exert a detrimental effect on the LBR. The message of this study is important in counselling of patients and planning out treatment. Further research on interaction between male and female age will increase our understanding of this matter and help to establish whether ICSI procedure is more appropriate for older male partners even when there is no apparent semen abnormality.
