I haven't seen any men breastfeeding lately. Nor do fathers regularly go through post natal depression or suffer the other ailments of pregnancy. I suggest you talk to some mothers (or your own) before making such absurdly informed assertions.
Not trying to imply that it doesn't. It is a stressful situation for everyone. But the rates in women are significantly higher. (Ironically being a stay at home mum can be isolating and it might be better for her health to go back to work...) One analysis also found a small be definite correlation between a mother being depressed and also the father. The incidence varies strongly depending on risk factors (smoking, obesity, poverty, trauma), form 10-25% in women, and about 5-10% in men (though men tend to under self report..).
