A recent study conducted by a team of researchers suggests that a father’s age doesn’t significantly affect the success rates of in vitro fertilization (IVF) or the chances of having a live birth, in contrast to the notable impact of a mother’s age. While older fathers might have certain health conditions that can affect their offspring, this research provides comfort in knowing that paternal age is generally not a barrier to conceiving through IVF or donor egg treatments.
The Effects of Age on Fertility
When it comes to fertility, age is a crucial factor, especially for women. It’s widely acknowledged that women aged 35 and above face challenges related to egg quality and quantity. As both men and women age, there’s an increased risk of genetic issues, which can lead to miscarriages; however, this risk is much more pronounced for women.
Male infertility can often be addressed with treatments like intrauterine insemination (IUI) or IVF with intracytoplasmic sperm injection (ICSI), where a single sperm is injected into an egg. In contrast, age-related infertility in women is typically more challenging to navigate. While many women may start with simpler methods like IUI, those who are older often see better success rates with IVF or donor egg treatments.
Investigating the Role of Paternal Age in IVF Outcomes
Researchers from various institutions examined data from a significant number of patients to determine how a father’s age influences the success of donor egg IVF cycles. The study focused on 5,873 donor egg cycles from 4,309 patients treated between 2004 and 2014. While it was observed that older fathers had decreased semen volume and sperm motility, these factors did not negatively affect the outcomes of donor egg IVF.
Implications for Couples
The findings of this study indicate that an increase in paternal age does not correlate with lower IVF pregnancy rates or fewer live births. Couples facing age-related concerns are encouraged to discuss the implications of both partners’ ages, especially regarding genetic risks in children.

In summary, this study offers reassuring insights for prospective parents: while maternal age remains a significant concern for fertility, paternal age seems to have a far lesser impact on the chances of successful conception through IVF or donor eggs.
