Hi dragonfly,

I had always thought that caffiene was not good for either partner who where TTC (even though I know heaps of people who drink coffee / coke and have never had problems falling pregnant). I quickly did a google search on caffeine and sperm production and found this extract from an untitled Australian Document:


Caffeine
Large research studies have been undertaken in Europe and the USA to ascertain whether coffee consumption is related to infertility. The results however are conflicting and difficult to interpret. The authors of one study concluded that a high level of coffee consumption is associated with an increased risk of delayed conception. One study found that as little as one cup of coffee per day was enough to increase the time taken to get pregnant. Another study of nearly 3000 women found that coffee consumption was not associated with infertility. Other studies have shown 2-3 cups of coffee per day is associated with an increased risk of miscarriage during early pregnancy.
Very little is known about the impact of coffee consumption on semen quality, although in vitro studies have demonstrated that caffeine can enhance sperm motility. There is little evidence that coffee can improve the fertilizing capacity of sperm. In men who drink coffee and smoke, deleterious effects on sperm motility and vitality have been observed.
The article is interesting. Try consulting your doctor too to guage there opinion. I guess we just need to make our own informed decisions. Best of luck with TTC.
