Like I said. I am pretty glad I dont have to think too hard on this issue... However it came up in relation to my game and thus I had to give it some thought... Now to answer I feel I myust tread veeeeeery carefully here.
I think that the same technology to splice the genetics in a female/female pairing would also apply for a male/male pairing, although a donor egg would be required.
We know that with some alien technology men can get pregnant (just ask Trip Tucker), we also know that in an emergency the Transporter can be used to transport a feotus to a surrogate womb (just ask Kira Nerys)... also of note; said surrogate doesn't neccesarily have to be of the same species, as long as its mostly geneticaly compatible (long term care seemed to be required for the duration of term). This also implies that surrogacy is all fine and dandy too, another option for male/male couples.
There is also the option of a technological womb, and in the setting of the game in question (post 2380's Borg dissolution) there may even have been advances gleaned from Borg technology that enhances this science.
I would imagine that there is still a certain amount of discussion on the issue, but rather than this discussion focusing on the parents sex as it would do now, it would be on the use of technology and how close the science is to augments... (as TDK has pointed out that some of the same science may have been used)
