What is the result of a genetic mutation that disallows female offspring?

Premise: Assume that one man has a genetic mutation such that his gametes (sperm) never have an X-chromosome. Unlike most men (who have a roughly 50/50 chance to sire a male or a female child) this man can only sire sons.

Assume further that this mutation is 100% hereditary such that every son born to his line will have the same mutation, siring sons.

• How long might it take for officials to notice that something was wrong?

• Under what circumstances would this be declared a problem by the government, such that it might act to stop further procreation?

• What cultural or sociological conditions would increase or decrease the likelihood of detection?

• Is there any plausible scenario in which the result would be catastrophic population collapse in a region or worse?
