I know in my clinic, it is common to see only the woman presenting for treatment. The reality is, it takes two to tango.

The upside – treating male fertility is usually more straightforward, and produces fabulously measurable results. Awesome!
Compared to the rest of the animal kingdom, human sperm is not amazing. It is actually thought to be the worst quality of any mammalian species. And I suppose this is not outstandingly shocking when we consider our men are exposed to a HUGE amount of biological and environmental stress, compared with the average monkey. Many men feel that if they are performing sexually, they are fine. However this is not the case. Illness, nutrition, trauma and toxicity all play their role in preventing sperm from being the best they can be. So what can we do to supercharge sperm? Lots!
Temperature
Sperm don’t cope in the heat. Thankfully, the male body is wonderfully designed to hold sperm away from the direct heat of the body in the scrotum. Brilliant! The only problem is, tight jocks, wetsuits, cycling shorts, saunas and hot spas all negate this well designed process. Sperm like an optimal temperature of between 34 and 36 degree Celsius. Any hotter than this and their number and function start to suffer. Now I’m not saying that going for a surf is going to annihilate all your sperm, not at all. But if numbers
