dh taking antibiotics whilst ttc. could this cause birth defects/mcs?

[kalo12]

he was taking antibiotics two weeks ago. could this cause problem ?

Nope, sperm don't last very long, they are either excreted in urine or um.... got rid of via another mean They live for about three hours or something like this so his body is constantly making them. The chances of them having antibiotics in them for 2 weeks are zilch.

but it takes 90 days to make sperm

I can't say as I've seen any research into the effects of antibiotics on sperm. Loads of men take them every day. It can't take 90 days to make sperm, men wank at least once a day, this means no sperm would be ejaculated for 90 days, think about it if sperm took 90 days to make then you could only try to concieve once every 3 months or so.

no they are making sperm constantly but the sperm that is ejaculated has had a 90 day manufacturing process

hold on.

No.

humrep.oxfordjournals.org/cgi/content/abstract/13/7/1878 says no, it's a good journal, well respected.
