Why would they cause cancer (any more than wifi/general EM radiation)? It's not ionising radiation as far as i know and short bursts of exposure to any sort of radiation is fine - people live in Chernobyl without any side effects and the background radiation level there is substantially above the norm.
Do you understand the difference between EM radiation and particle radiation? Unfortunately the difference between the "radiation" fallout from nuclear weapons and disasters and the "radiation" from cell phones is lost on the media. Particle radiation is high-energy particles of matter, e.g. alpha particles, that smash into atoms and molecules and cause damage at the molecular level to your DNA.
EM radiation is pure emitted energy. Light is EM radiation. Heat is EM radiation. Microwaves and radio signals are EM radiation. The wavelength of cell phone radiation is so long (between 10 and 30 cm) that it is literally impossible for it to interact with single molecules and cause damage to your DNA. However, at that wavelength it can still transfer heat, like a microwave oven.
The notion that cell phone radiation causes cancer directly, as in through genetic damage, is ludicrous. It would only be able to cause cancer by causing localized heating of parts of your brain which may set into effect a cascade of effects that may manifest as cancer. However, I think this is unlikely.
As for sperm counts, I think carrying a cell phone in your pocket is about bad for your sperm count as would be carrying around one of those chemical warm packets or wearing tighter underwear--the extra heat is the only culprit.
