Not sure why you're being downvoted.

I'm Korean born, but spent most of my life in the US. My wife is a much more recent immigrant so she is a product of the Korean education system as well as the Korean corporate world and all that entails.

We have some friends that have adopted, so are aware of the potential issues. Most of them seem perfectly fine, but one had some initial problems with the child adjusting to his new life. These were all toddlers (3-5 years old).

Probably because it comes through as tall claims based on anecdata? But I've lived in Europe, America, Asia, ME & Australia (also visited every SEA country) and the prevalence of male feminization & rich-people obesity (esp central adiposity) in certain regions is quite staggering.

And almost every single person I know personally with difficulty conceiving (various races, various countries, various diagnoses including ectopic/fibroids/undiagnosed) had some obvious-to-me metabolic-syndrome/cholecalciferol/ferritin issues going on, particularly Asian-sub-continentals in northern sun-starved climates who were not supplementing cholecalciferol.

Aside: How does one tell downvotes? I suppose I should look in the FAQ. IIRC only established members can downvote. Despite my account being from HN's 2007 inception, I do not have enough established-karma to have my own downvote button. So I generally don't bother about it, as it's a bit of a circular dead-end karma-spiral which I had thought the HN mechanics were supposed to avoid.

Downvotes: I'm so glad you asked, as I often wonder the same on "you're being downvotes because" comments. Eventually a post goes grey, but prior to that I have not been able to spot an indicator of downvotes happening. And I do have the downvote button.

There is a karma threshold for downvoting, you likely haven't reached it yet. It's in the FAQ.

However, as to HN culture, typically anyone complaining about downvotes will be further downvoted. It usually does not matter what the rest of the comment says, if you complain about downvotes, HN will give you a lot more of them. I like to think that it is a way for the community to remind individuals that these are all imaginary points anyway and to not be attached to one's karma number anymore than one is attached to the number of the nearest speed limit sign.

What do you mean by male feminisation? I get the impression from context that you're referring to biological differences but that could easily be interpreted as "man aren't real men these days and that's why they can't conceive".

I think they mean feminization in the biological sense: It's the reason fat men usually have visible breasts: the body has a pathway for converting cholesterol into estradiol[0], excessive cholesterol causes some feminization due to that.

This is exactly what I meant. Particularly visible in richer social strata in SEA, especially in the Philippines and to a lesser extent in Malaysia & Singapore. The amount of sucrose consumed in that first country beggars belief. Everything at breakfast is full of sucrose, even the pork & of course, bacon.

Also, I appreciate your use of the singular "they" :-)

Maybe he's talking about the big drop in testosterone in males? Even things like hand grip strength have decreased.
