There are male Made To Move Barbies.
The BMR1959 have the MTM bodies however, these are dolls targeted at adult collectors so their price is about $30.
There is a new Ken with a wheelchair which has a MTM. He might be the cheapest MTM male doll at $20.
Another option, but maybe the most expensive one. Is there were a Superman and Batman doll released with the Batman v Superman films. These dolls have the MTM joints but unlike Ken, these dolls have a bulkier more muscly bodies. Similar to BMR1959, these were collector dolls so buying them might be expensive.
For non-Mattel dolls
There are the Body Kun Dolls. These were created to be an alternative to the wooden mannequins. They come with stands and extra hands and there is also a chibi version and ones with more anime proportions. The only thing I will say about them is that they are small, like the size of an action figure.
