They have a dick though  

 That’s usually an advantage in sports  

 + balls 👀 

 Let’s not forget a healthy dose of testosterone 👀 

 But it's a real disadvantage if you get caught in a country like they're from. I seriously doubt they could be guys. Not in those countries. No chance! 

 No, apparently not  

 No boobs either? 

 Nope  

 Apparently the one on the left does. Seen a video with the bulk in the pants and the person scratching it.

As for undidclosed documents there is many including previous test results that caused a disqualification from a boxing event. According to Wikipedia  

 Khalef has XY chromosomes and testicles. He's got all the genetics and hormones of a man, and went through male puberty.

He's missing a penis. But penises don't actually do very much biologically speaking. You wouldn't tell a man that he's no longer a man just because he lost his penis in a chainsaw accident. What matters is what's inside you. And during puberty what's inside you is a whole lot of hormones. 

 You sound so sure. No clear biological advantages? Top 2. What documents his balls are coming out of his shorts. 

I, Justin Trudeau could fuck up 20 woman at once.  

 I'm not sure about this at all.
There might well be biological advantages...
 

 It's is my opinion btw that IF there are biological advantages, they should not be allowed to compete. Or maybe there should be a separate category.
However, the whole issue is above my pay grade and more complicated than we think.

Joe Rogan had Carole Hooven on his show, where they go into details....
