How will life find a way if all of one sex of the human species dies?

Hypothetically, since it will never happen, let’s say all of the females on the planet die off in three years due to some virus mutation, a virus brought to Earth by a meteor, whatever, it attacks female chromosomes. All females from the youngest to the oldest, the tall and the small are dead in three years from the introduction of the virus and science has no known way to block it or stop it. How would life make a way as was indicated in Jurassic Park? Given life would have to make a way in about 80 years or less, because that is about the life span of babies bone when the last woman dies, and if life doesn’t make a way by the time the last man dies, humans cease to exist on Earth. If it were just women left, would they fare any better?
