"Exercise is meant to make us hot-blooded, but too much of it can sap our sex drive, a new study has found.

Research has tended to focus on how our sex drive benefits from regular exercise. Aside from the confidence-boost exercise gives us (and confidence leads to greater sexual satisfaction), there are the physiological effects. "

"it is not the first study to show the "negative impact" of endurance exercise and elite sport.

She says there are two reasons for this – the psychological and the physical. It is known that intense exercise can negatively impact testosterone (which affects both sex drive and sperm count), but Quirk adds:

"There's a parallel between immunological function and sexual interest and there is a negative effect – in elite sports and endurance athletes – on immunological function."

Quirk adds that moderate activity provides "a reasonable amount of benefit" but when we start pushing ourselves hard for extended periods of time, we become mentally and physically "spent".

"Sex will be very low on the list," she says. "

"Technically referred to as bipolar androgen therapy (BAT), the treatment is aimed at patients who have metastatic prostate cancer that's otherwise resistant to treatment by chemical or surgical castration. It's based on the idea, supported by previous studies, that high doses of testosterone can interfere with cancer cell division in some cases, and actually cause some cancer cells to make breaks in their own DNA."
