"XX" Men

Question - is it true that some men can only father girl babies? I
heard that some men cannot conceive a male child.
For mammals, the father does determine the sex of the baby, since the
mother always provides an X chromosome and the father provides either an
X or a Y. Scientists have found differences in the behavior and
survival of sperm carrying X and Y chromosomes. These differences can
be greater or less for different men. In humans, there are generally
more boys born than girls.
Recently, studies in a number of industrialized countries have reported
that the proportion of male babies has decreased. Studies are on-going
to explore this issue and people have theorized links to pollutants,
timing of conception, smoking, stress and other factors. Additionally,
some types of mutations in either the X or Y chromosome have been found
to lead to more female births. Probably the biggest effect is just
random variation. Many smaller families would, by chance, have just
boys or just girls.

I think you are talking about sex reversals. Genetic testing due to infertility concerns
and biotechnology has led to the discovery that some females are actually XY rather than XX.
There are males that are XX rather than XY. These individuals are rare to say the least
and the details of why they exist lies with mutations and abnormal chromosomal structures. The gene
for maleness is either misplaced in the sex chromosomes or this gene, called the SRY gene, is not
turned on to set up the chemistry to produce a male. The female is the default in our species.
However, many of the XX males are sterile by what I have read. If any are fertile, yes, they would
produce only girls since they only have X chromosomes, unless they past on the reason that they are
male rather than female to the next generation. There is not a lot of information as yet on this
topic.

PGNx Media
The three main characters are very detailed and authentic to their film counterparts. Wolverine is bigger than the others; Ice Man retains that young look, while Nightcrawler looks as weird as usual. The animation is solid, as well.
88
GameZone
A solid and fun action game featuring one of the coolest superhero teams ever. With an excellent story with plenty of twists and turns and a host of familiar characters, fans will certainly have a lot to enjoy despite the linear levels.
80
Worth Playing
It's a good-looking, smooth-playing title that captures some of the mystique (ha-ha) of the comics and movies. Where it fails is in the limitations placed upon it.
78
Game Chronicles
Some of his levels are filled with ridiculous amounts of enemies, and even though the levels appear to have multiple stages or sections, there isn’t a checkpoint in sight. I love a challenge, but I hate mindless repetition.
77
GamingTrend
One upside to it is that the game is roughly six to eight hours in length so if you have a weekend to kill then this one may be up your alley. It certainly looks pretty, sounds great, and the ragdoll physics are put to great use. It just would have been nice to play a challenging game instead of one where nothing is balanced out.
65
WHAM! Gaming
Fortunately there are a few interesting boss type fights in the game to keep it from becoming overly stale including some interesting members from the Brotherhood of Evil Mutants.

Cheat Code Central
Everything considered, the gameplay, the graphics, the dialog, the music, make X-Men: The Official Game an officially average game.
60
Times Online
Nice graphics and smooth gameplay are no substitute for imagination.

Unless my brain is being fried by professor Xavier's Cerebro machine, I quite enjoyed X-Men: The Official Game. [Aug 2006, p.81]
59
GamingExcellence
The killing part is fun when you find the special X-Men powers amusing, but that river runs dry approximately an hour into the game, which is actually a decent ratio when compared to the total playtime of about six hours.
57
IGN
The combat and stage design are substandard in every way too, enemy AI is ordinary coin-op fare, and the presentation elements are nowhere near the level we've come to expect from Marvel or Activision.
56
GameSpot
It's not that it's entirely broken, mind you, but X-Men's missions are entirely generic and devoid of captivating content, and there are enough annoying little glitches and other obnoxious things prevalent throughout to give the game that thrown-together feel.
55
Next Level Gaming
Only controlling three characters, no multiplayer of any kind, and reverting to basically a 3rd-person "beat 'em up" is not the way to take this franchise.
55
eToychest
One of the chief problems with X-Men lies in its mission structure. Branching paths are often a good thing, but when they are as disconnected to point where any semblance of an underlying plot is compromised at these are here, any benefit of such a feature is wasted.
54
PC Gameworld
There’s nothing here that warrants a buy. Fans that want to know why Nightcrawler wasn’t in the movie will want to check out the game from your local video rental store.
50
1UP
While the gameplay does have its high points (again, mostly surrounding Nightcrawler), it's also quite often littered with monotony thanks to seemingly nonexistent enemy A.I., confusion (poor level design), and frustration (glitches, a sometimes lack of checkpoints, and uneven challenges).
50
AceGamez
It's sad to say, but after playing this I spent a good few hours playing Wolverine's Revenge and having more fun in the process - and that game is over three years old!
49
PC Gamer UK
Lots of swearing as you protect a world that hates and fears you. [Aug 2006, p.85]

A solo Nightcrawler game could rock, but this team effort is cash-in gibberish. [July 2006, p.100]

PC Gamer
I need Professor X to wipe the memory of this game from my brain. [Aug 2006, p.85]
40
Yahoo! Games
Like many games of this style, there is some vague, half-guilty pleasure in the mechanical repetitiveness of the game's combat. But ultimately, X-Men is in the time-honored tradition of licensed games -- rushed, derivative, and well worth avoiding.
39
Jolt Online Gaming UK
As it is, X-Men: The Official Game is “officially” a horse’s turd of an experience that’s approximately as painful as Wolverine’s claws inadvertently sliding out while he’s wiping his arse.
35
Play Magazine
X-Men: The Official Game is pretty awful. [July 2006, p.71]

games(TM)
When accurately describing videogames, we tend to use the word ‘dross’ rarely, but this particular X-Men title has forced the word from us in a spectacular fashion. [July 2006, p.130]

Edge Magazine
Had The Official Game provided a consistent overall challenge, it would have been bearable, if unexciting. But it hasn’t, and it isn’t. [July 2006, p.88]
30
Pro-G
The idea of giving the player three fairly unique characters to play as is good one, but the game design verges on plain stupid at times.
25
The Onion (A.V. Club)
Almost everything about this movie cash-in is cheap and incompetent, from the short, forgettable levels to the poor control system to the hand-crampingly repetitive action.
20
Computer Games Magazine
There's virtually no effort made to adapt the controls to a PC, so make sure you've got a gamepad handy. Although the far better alternative is to just have a better game handy. [Oct. 2006, p.75]
