(InvestigateTV) - About 10% of Gen Z and Millennials say they are putting off having children because they are unsure how they would afford it or what starting a family would mean for their long-term finances, according to new research from Northwestern Mutual.

Kate Michaels, a managing partner at Northwestern Mutual, said money is pushing family plans down the road while another clock keeps ticking in the background: fertility.

If a couple faces infertility, many end up considering IVF, which Michaels said can be emotionally and financially overwhelming.
