important factors for sperm banks
Not that I've used them, but as far as I understand, sperm banks provide a fair amount of data on sperm donors including education. If you stick with Ph.Ds the baseline IQ level should be decent. Besides, sperm banks are a customer-oriented business. They will look for factors which women demand.
Exactly. Most women demand attributes that they themselves find attractive in mates e.g. height and other appearance-related factors. Transhumanists don't make up most of the female population.
