In speaking with a friend, she tells you that she is on a fertility drug and is excited to have twins. Which of the following is the most appropriate way to respond, based on what you have learned from the text?

Fertility drugs increase the rate of multiple births by increasing the probability of releasing more than one ovum, which might lead to fraternal twins. But there are no guarantees. The use of fertility drugs is in no way related to giving birth to twins. Having twins is unpredictable, and modern medicine has not been able to alter the process in any way. Infertility drugs have been shown to increase the rate of identical twins; however, these pregnancies have a much higher rate of miscarriage than non-multiple pregnancies.
