If the Catholic Church teaches "babies and bonding", is having sex at an old age a sin?

I was recently listening to a podcast between [Stephanie Gray Connors](https://loveunleasheslife.com/about) and [Trent Horn](https://www.trenthorn.com) on the unethical nature of IVF. One argument that was brought up was the idea that the Catholic Church teaches "babies and bonding", which is why IVF and birth control are wrong. IVF doesn't have bonding, and birth control doesn't have babies. But at a certain point, a woman becomes unable to have children. So after that point, would it be unethical for the man and woman to have sex (according to the Catholic Church)?
