A long-standing patient came in today for treatment. Her three previous pregnancies have resulted in only one baby and she wants to avoid a miscarriage this time.
I asked her about the quality of her husband's sperm and she looked at me quizzically, saying: "I have got pregnant 3 times already so there is obviously nothing wrong with him".
She had no idea that less than perfect sperm could be a contributing factor in her miscarriages.
Googling "male fertility & cafeine" produced 178,000 hits with some of the first being:
- In about 40% of infertile couples, the cause of the infertility lies with the males
- Caffeine and alcohol affect men much as they do women. Both have even been implicated in male reproduction
- Caffeine use is associated with a decreased potential to produce a pregnancy. Studies show link between caffeine and infertility.
- Whilst one site said: "a positive effect of caffeine on male fertility caused by its apparent ability to stimulate sperm motility" but there is nothing to suggest that these stimulated sperm are more fertile or able to produce a healthy fetus.
Then there was:
- Another reason to watch your waistline: Fat men have bad sperm.
- Young men warned of laptop risk; Heat could damage fertility
See my previous post on how to improve your fertility.
