The mere mention of his name can make men weak in the knees, but you'd be hard pressed to find someone who hasn’t heard of Dr. Ron Weiss in Ottawa. Little wonder - the physician has just performed his 50,000th vasectomy.

“I’ve got 3 kids in a 3-bedroom house,” jokes Ottawa resident Chris Lord, “so I don't want a bigger house.”

Lord is about to undergo a vasectomy, and his comfort level comes from knowing he's in capable hands. Dr. Weiss performs the scalpel-free, needle-free technique 70 times each week. Last Monday marked his 50,000th vasectomy. He introduced the technique to Canada in 1992.

“You have a procedure that literally takes minutes,” explains Dr. Weiss. “It's painless, has a low rate of complication and is the most effective form of birth control. Men are stepping up to the plate.”

Dr. Weiss explains that he's using something called a jet injector for anesthesia to freeze the area. When the area is numb, he makes a tiny opening in the scrotum to access the vas deferens.

“The vas deferens is the tube that carries the sperm,” he explains. “It’s just like spaghetti, looks just like spaghetti. I pull it out, cut it, block it and tuck it back in and do the same thing on the other side. This is considered the gold standard around the world.”

In his spare time, Dr. Weiss doubles as a musician. He's just released his third album, though it is his medical day job that is his true passion.

“I wouldn't do this if it wasn't fun, and it is fun," he says. "I’m dealing with healthy young people who want a service that will enhance their sex life, take away some of their worry.”

Now, that's not to say men don't feel nervous coming here.

Debbie Halton-Weiss, who is married to Dr. Weiss and works with him at his Glebe medical office, says even the big guys go down from time to time.

“There was one man,” recalls Halton-Weiss, “he was 7-feet tall, comes and stands where you are, and goes right down. He doesn't even say the word vasectomy and he's down.”

About 15 minutes after Chris Lord walked in to the examination room, he’s done and none too worse for wear.

“I feel great,” he says. “I'm supposed to take it easy but I don’t feel any different than I did walking in.”

Except, of course, he knows that 3-bedroom house now is going to fit his family just fine.
