All Squadmates can die during the course of the Mass Effect series.
Of those squadmates, only the following could produce an offspring of Shepard,, all others are either not a compatible species or are non-romanceable:
- Ashley (Male Shepard): Can die at Virmire or the Citadel in ME3. Or a low EMS finale at Earth, where they are killed by Harbinger.
- Kaiden (Female Shepard): Can die at Virmire or the Citadel in ME3. Or a low EMS finale at Earth, where they are killed by Harbinger.
- Jacob (Female Shepard): Can die at the Collector Base or during their mission in ME3. Left Shepard for another woman.
- Jack (Male Shepard); Fertility status unknown, possible infertile from heavy experimentation. Can die at the Collector Base or at the Cerberus Base in ME3 if not recruited in the events prior.
- Liara (Either Shepard): Offspring would be Asari. Liara can die during a low EMS finale at Earth, where they are killed by Harbinger.
Miranda is not listed here as she is confirmed infertile in the Shadow Broker's data files.
--------------------------------
Now for the following facts to contemplate:
- The issue with a female Shepard giving birth is that the events of the Mass Effect trilogy do not allow any time for Shepard to have gone through pregnancy. The only possible way that a human Shepard child could exist is if she was made pregnant by Kaiden before she was then killed by the Collectors at the beginning of ME2, and Cerberus took the fetus inside of her, revived it as well, and made it a cyborg. Even if this was true there is the possibility that the process would leave it infertile, not to mention heavily mutilated and possibly unable to grow. It would be roughly two and a half to three years old by the events of Mass Effect 3. . . one would believe she would have found out about this abomination if it existed.
The other possibility is that she was pregnant right before she died in three out of the four endings of Mass Effect Three, assuming one has a high EMS when selecting Destroy.
- The issue with a child born from a Male Shepard's love interest is similar in principle to that faced by a female Shepard: there is no time for a child to be born from Ashley or Jack. Of these two characters Ashley is the most likely candidate, as we do not know if the extensive testing on Jack has made her infertile. Even if she has the potential to be fertile, Jack (and Ashley) can die in numerous ways leaving no room for birthing let alone pregnancy.
However, if Ashley was indeed pregnant and gave birth to Shepard's child, which would have occurred at some point before the official beginning of Mass Effect 2, one would believe that this is something that she would tell him at any of the points they have communicated during the events of Mass Effect 2 and Mass Effect 3.
- The other possibility is that Liara may or may not have mind-molested Shepard at multiple points in the trilogy, as their system of reproduction can also be used as a form of information transference if I understand that concept proper: Any non-Asari would not be able to tell the difference unless it was an Ardat-Yakshi, in which case they would feel a lot of death. This brings up a few moral questions I do not believe the Developers would be willing to talk about. This could be cleared up by canonizing Liara as Shepard's romantic interest (see conclusion)
- The final possibility is that Shepard had a child prior to the events of ME1 with some other romantic partner, but you think that would be mentioned to the player at some point.
--------------------------------
The most notable issue is in canonization. Bioware does not seem willing to canonize an ending, as the move to Andromeda seems a deliberate attempt to avoid the Shepard trilogy and forge a new path through the stars.This does not just mean they do not want to canonize an ending, however: it is clear that they do not want to canonize anything: Shepard's gender, Shepard's love interest, or the various other decisions Shepard made during their adventures.
By moving various races to Andromeda they can avoid mention of certain fan-favorite races being wiped out (EX. Krogan on the Ark were not subgegated to the sabotaged Genophage or Quarians on the Ark were not at Rannoch when the Geth destroyed them) by the product of some of these choices. The Shepard is a legend, and no one knows the full details of their story, for it was a long time ago. . .it's best to keep it that way without someone appearing with the risk of acting like a self-entitled king/queen.
