Ah, I'm sorry, but I have to disagree and here's why...

For starters, the vast majority of men don't even think about selecting gifts until Christmas Eve.
True, but that's why he has the Elves make the gifts and label them. I believe all he does is make the list and checks it... Some most men I know do rather well. Think about it... "Honey, I need you to fix the sink!" "Okay dear, I'll need to go to the hardware store and get. 1 a wrench, 2 a rubber washer, 3 some sealant, 4 a new power saw... etc.

Another problem for a he-Santa would be getting there. First of all, there would be no reindeer because they would all be dead, gutted and strapped on to the rear bumper of the sleigh amid wide-eyed, desperate claims that buck season had been extended. Blitzen's rack would already be on the way to the taxidermist.
Even hunters know you don't kill "all" of them. You just use Next years targets for transportaing this year.

Even if the male Santa DID have reindeer, he'd still have transportation problems because he would inevitably get lost up there in the snow and clouds and then refuse to stop and ask for directions.
Who needs directions? You going to everyhouse and drop off the gift. If they happen to be one of the many families that doesn't believe in Christmas, you just, use the restroom, raid the fridge, and go on your merry way.

Men can't pack a bag.
again Elves...
Men would rather be dead than caught wearing red velvet. Men would feel their masculinity is threatened...having to be seen with all those elves.
He's like any man who doesn't want to hurt his wifes feelings, and she probably bought if for him at a Penny's sale. "Honey, you're going to look darling in this!" And who saids he hangs out with the Elves? He just has them do all the work and then takes the credit... Sounds like a man to me... YEP! I BBQ'D them steaks myself, best danged dinner I've had in months! (and the wifes thinking... what about the taters, corn, beans, rolls,... you get the idea)
...Men don't answer their mail.
I've never gotten a letter back from Santa, have you?
... Men would refuse to allow their physique to be described even in jest as anything remotely resembling a "bowlful of jelly."
He may not like it... but who can control the press these days?
...Men aren't interested in stockings unless somebody's wearing them.
Good point, but it's part of the job... what can you do...
... Having to do the 'Ho Ho Ho' thing would seriously harm their macho image.
You see, this is a common misconception, he actually says. Woo hoo hoo... and whispers, thank God no one saw me in this outfit here either.
... Finally, being responsible for Christmas would require a commitment.
Again, good point, but I'd bet anything, Mrs Claus is the one who actually got him to get up a leave by having he elves over for tea after all that hard work.
I'm sure you can see my points. And I may be wrong, but I seriously doubt it. After all, If santa was a woman, he'd stay to chat at the first house and couldn't get to all the rest in just one night.
