A study by Newcastle University researchers has found that three-person in vitro fertilization is safe (does not adversely affect embryos) and can be routinely performed. Three-person IVF allows the transfer of donor mitochondria into an embryo in order to prevent mitochondrial disease:
Published today in the journal Nature, scientists at the Wellcome Trust Centre for Mitochondrial Disease at Newcastle University report the first in-depth analysis of human embryos created using a new technique designed to reduce the risk of mothers passing on mitochondrial disease to their children, which is debilitating and often life-limiting.
[...] Today researchers, in a study involving over 500 eggs from 64 donor women, publish results that indicate that the new procedure does not adversely affect human development and will greatly reduce the level of faulty mitochondria in the embryo. Their results suggest that the technique will lead to normal pregnancies whilst also reducing the risk of babies having mitochondrial disease. The results of this study will be considered by the Human Fertilisation and Embryology Authority's (HFEA) Expert Scientific Panel. The HFEA will ultimately decide whether to issue the first licence to a clinic. A licensed clinic would allow couples affected by mitochondrial disease to have the choice of whether to use pronuclear transfer to try and have healthy children.

Fair enough, but a group of men could also create just males by picking X and Y chromosomes. The only things they are missing are an egg, which would have to be synthesized from scratch or transformed from another cell somehow, and an artificial womb. Those are engineering problems... should be a few men out there willing to tackle those, right?

or create female offspring by picking X chromosomes from two different males?

I already wrote that in another comment.
The point of the post you replied to is to show that men could exclusively produce male offspring with no female involvement. However, it would be considerably harder than women exclusively producing female offspring with no male involvement, so that will happen first.
I'm sure both scenarios have already seen extensive coverage in science fiction.
