Defending champion Murray came into the tournament nursing a hip problem, which appeared to hamper his mobility as he lost out in five sets to Sam Querrey in Wednesday's quarter-final, having twice been a set to the good.
The world number one responded: "Male player".
Federer plays Raonic on Wednesday for a place in the last four at the All England Club and in a re-run of last year's semi-final, when Raonic overpowered the Swiss in five sets. I wasn't getting enough power on my serve to put him in any bother there. "That was on my mind", he told reporters. "I tried to get it in the condition where I was able to play". And everything seemed to be falling my way then.
I didn't start my best, but I just kept with it.
The American stepped up a gear in the fourth and fifth sets, winning 12 of the last 14 games to wrap up arguably the greatest victory of his career.
The world number one could not overcome the American Sam Querrey (28th) and tilted in 5 sets, 4-6 / 6-4 / 6-7 / 6-1 / 6-1. Querrey, the No. 28 seed, will face Croatian Marin Cilic on Friday.
Murray, ever the feminist, was quick to call out the reporter, interrupting him mid question to correct the mistake.
"Like I said at the beginning of the tournament, I'll be able to get through seven matches if that's what I have to do", the Scot said after his win over Benoit Paire on Monday. "I wasn't that far away from doing that". But the other guys are playing well.
"I'm just so, so happy to be in another semi here", Federer said.
"That last point I was just hoping to hit the serve".
The older Williams sister, who at 37 is the oldest player now in the draw at Wimbledon, is the second-most decorated athlete there - male or female, and the most decorated overall with five singles titles, and six in the doubles - where she is the defending champion.
