Impact of parentage on superovulation efficiency. (A) The number of embryos collected per female aged 6-20 weeks significantly decreased with female age. (B) Frequency of ovulatory response in females that mated within the first 15 minutes of male access (<15) compared to those that mated after the first 15 minutes of male access. Females that mated within the first 15 minutes of male access were more likely to superovulate than those that did not immediately mate. Error bars are represented as + SEM. Asterisk represents a significant p-value (<0.05).
