Hi @Charlie74 the icing is just a recommendation from Wazza to help along the sperm production I think. My DH has low motility and mobility and some of his samples have been very viscous (so we're told). DH doesn't mind too much. I suppose the coolness helps them keep at the right temp as my DH is in IT so he's always got devices on his lap or near it. Plus he often gets stressed and this results in night sweats - aka terrible for the swimmers.
Ps we've Baby danced more often since the icing began so maybe that's also a stimulation thing? Who knows? I'm going with it 😉
