So you're talking about the mere act of conceiving a child then? Well, that's just ridiculous. First, nobody was congratulating him on fertilizing an egg. They were congratulating him, in advance, on what we know is going to be a lifetime of trials, tribulations, and triumphs. I thought that would be fairly obvious.
Second, it's not nearly as simple as you imagine. Animals give birth without much fanfare. Humans, not content with the mortality rate amongst infants in the animal kingdom, go to far greater pains. It's unbelievably difficult on the mother, physically, emotionally, and mentally. And, more unbelievably (given how easy it apparently is), it's spawned an entire speciality of highly trained medical professionals.
I have a coworker right now who gave birth early. Her child was TWO POUNDS. Happily, they're at one of the best Neonatal Intensive Care Units in the region, and the baby is slowly making progress. When the baby reaches a weight that's self-sustaining, I will breath a huge sigh of relief.
In the meantime, the parents have rented an apartment closer to the hospital. (A hospital far from where they live, but it has the best reputation for neonatal care) So the father can still see the baby despite having to return to work to keep them solvent.
That sound easy to you?
