Like Platinum Yorkies said worms can't be passed through the male's sperm; the eggs are passed and shed in the digestional tract, uterus of pregnant Mom to pups, or through the mammary glands while nursing.
However, if the male had worms and was cleaning himself or stepped in his poo or another's poo contaminated with eggs and then licked his feet and then kissed your dog - she could get worms this way. Or, if he pooed in your environment, and your Mom stepped in it and then licked her feet she could get worms or if she licked her pups she could give it to them this way. That is why it is so important to clean up poo quickly to keep worms from being passed back and forth.
One negative test is not proof positive that a dog is worm free that is why most vets recommend worming all pups and Mom starting at 2, 3, 4, 6, 8 and 10 weeks with pyrantal pamoate (not all wormers can be used on pups under 8 weeks, read the directions). With Yorkies though I feel any use of toxins unnecessarily should be avoided so I test Mom after birth and again at 4 weeks post whelping, no sign of worms, no deworming and then I again test the puppies at 8 weeks (or sooner if I see any signs of worms).
Fecal exams are cheap and don't require an appointment, or at least with my vet.
