Often claimed to have been discredited.
Absolutely proven in certain areas: height weight, hand size.
Compelling evidence for personality.

Very strong evidence for IQ, and this is true regardless of what IQ means.
Opponents are free claim it isn't true in a particular area, and in some cases this is likely true. Robert Brockway mentioned the possibility of counter-examples in this original article.
Male variability doesn't claim to be universally true just generally true.
Robert Brockway postulates that counter-examples exist and that, in particular, female sexual response is a counter-example. Women, on average, take longer to achieve orgasm than men, but more importantly there facility to orgasm varies significantly more. A man with a widely variant sexual response may ejaculate less frequently. This would be a negative selective pressure which would favour men with a more conventional sexual response. Thus natural selection keeps the male sexual response within narrow bounds, overcoming male variability. In contrast female sexual response is able to vary widely.
