The evidence is convergent. Multiple independent sources reach the same conclusion, the underlying mechanism is well-characterized, and even the field's most cautious voices treat it as worth doing.
And fortunately, if the goal is fertilization, there are some margins for error that are introduced by the fact that the sperm can survive within the female reproductive tract for some period of days, thereby reducing the need for absolute certainty about the time of ovulation and so on.
