I’m a keen cyclist, but have been told that a hard bicycle seat and Lycra cycling shorts are not good for my fertility. Is this true?

Yes. Regular and prolonged cycling on hard bike seats can affect the nerves and blood vessels to the genitals by putting pressure on the perineum, so it’s best to use a gel seat to cushion this part of the body. Also, overheated testicles can temporarily lower sperm counts, so try to avoid tight underwear, saunas and hot baths when trying to conceive.
