So many moms I know who have done the IVF gamut end up hugely depressed and hating life with kid(s). The routine of the IVF becomes its own sort of holding pattern, especially if you have to do a lot of rounds before it takes. And then when it finally works you're subjected to 9 months of invasive medical shit and you're constantly worried you'll lose the pregnancy and have to start over again, and when the kid arrives it's often highly celebrated on social media while the mom privately cries to her friends that it's so different than she thought it would be.
People who do IVF should need to do some baby care first. It's awful to see people grappling with "this thing that shits itself is what we paid $75,000 for?!" because they never really understood the 24/7 nature of parenting and were trying to just "take the next step" they were expected by family and friends to take, regardless of the cost and difficulty.
IVF kids are also somewhat more likely to have a range of health issues, though people are really reluctant to discuss this. Kids, start in your 20s so you can have a much better chance of making your children from an evening of love and romance, not in a Petri dish after jerking off in a beige room at a fertility doctor's office. Plenty of people in their 30s conceive naturally, but your odds just get worse and worse as time continues its march.
