1. We can take a guess at some of the reasons.

And some of the consequences.

For example China's One Child Policy resulted in a severe bride/female shortage.
So now China has to kidnap women from nearby countries for their wife/sex trafficking rings.

If the Chinese were only allowed one child they chose to keep a male
child and discarded or killed the female babies. This has caused a lot of problems.
There are not enough women in the country for the men to have wives.
The farmers need wives to help run the farms and provide labor.

Also the Chinese kept the boy children because they thought they would
provide better for them than girls. They are finding out the boys have abandoned
their parents and the daughters look after them better. China had to enact a law
that children had to visit their parents so many times a year.

2. A lot of these countries rely on tempory immigrant labor, and

they don't permit these foreign workers to bring any family with them.

6. The Chinese farmers are butt hurt that the Chinese women won't marry them.

There are not enough women to go around and the women want to go to the big city
and don't want to be stuck on a farm.

So the farmers don't just want labor, they want wives.
So the govt is kidnapping women from other countries like NK, Cambodia, Thailand.
Or luring them to China on false promises.
Of course some foreign women will take the offer if the Chinese farms provide a better life for them.

5. No daughters, no grandchildren

3. I remember when Ruth Bader Ginsburg was appointed to the Supreme Court

She said something like “I want to live in a world where girl babies are valued just as much as boy babies” we haven’t gotten there yet, we’ve gone backwards

4. In the case of the Gulf countries

I think that the disparity may be because of migrants engaged in construction. The link has tabs which reference "migrant stock".

7. It is dangerous for a country have a large single male population

No women, no brides.

Young single men get bored, angry, aimless, have no anchor or purpose.
Makes a rebellion much more likely.

8. Women in those countries probably don't have many rights, either.
