A new study has found that in addition to the age of women, the age of men also plays a critical role in how successful a female is in getting pregnant.
The Human Reproduction study, published on June 30, looked at how advanced paternal age (APA) impacts live birth rates (LBRs) in IVF/ICSI treatment, two forms of assisted reproductive treatment. It took a retrospective analysis of 18,825 autologous IVF/ICSI cycles. Researchers found that among women under the age of 35 or over 40, the age of the male partner made little difference in their chances of giving birth.
However, among women between the ages of 35 and 40, the study saw a significant drop in the LBR if their male partner was 40 and above. Among 35- to 40-year-old women, the LBR was at 32.8 percent when the paternal age is below 35. This falls to 27.9 percent when paternal age is between 40 and 44, and 25 percent when paternal age is above 55….
