Serious question but cant find the right words to ask?

[Sophiasmomma]

OK PLEASE bear with me and help me!

I want to ask my Dr(or anyone here that might know) but I cant seem to find the right way to ask that will make sense....

I had 2 Miscarriages last yr (12 weeks and about 9 weeks) same situation baby just died...
I had all the bloodwork ups done and nothing is wrong.. we have 2 healthy kids prior to the 2 MC..
I wanted to know IF its possible for sperm to fertilize an egg but have something wrong with it?? Or is sperm just about fertilizing an egg? I dont know if im wording it wrong... Is it possible for a man to impregnant but because there "maybe" something wrong with his sperm it could cause a MC?

is there a good website if this is possible to read about?>


Im only asking because my Dr said it was ok to try again and well Im jsut nervous thinking what if its not me that has somethign wrong? What if 2 MC back to back arent just a fluke.......

TY for your help

Well....the average man has about 40% abnormal sperm. But there are two types of abnormalities....there's genetic and physical.

A physically abnormal sperm might have a really big head or small head, or have two heads or two tails, or a stunted tail, etc. Those sperm cannot fertilize an egg, as far as I know. Most of those sperm never even reach the egg, since they are bad swimmers. But if they did reach the egg, the egg would recognize them as abnormal and not let them in (I think....I'm remembering from my human anatomy/physiology class).

Half of a human being's genetic material comes from the sperm cell. A genetically abnormal sperm can fertilize an egg, but then the developing embryo will be abnormal and sure, it might result in a lost pregnancy. If it didn't, there would be a higher rate of babies born with chromosomal defects and such.

If you're really concerned about it, you could have your husband go for a semen analysis. Also, smoking, drinking, and other substances can cause sperm to mutate.

I'm so sorry for your losses. I'm going to take a stab at this...

I had a miscarriage about six weeks ago. The reading I've done on the subject suggests that most miscarriages are caused by chromosomal abnormalities. Those abnormalities can come from either the egg or the sperm, or from both. There is no test that will tell you which. One reason that miscarriages are so common is that we all - absolutely every one - produce the occasional chromosomally odd reproductive cell. On average, we produce more normal reproductive cells. The next pair are just as likely to fine as anyone else's.

It's completely possible for an abnormal sperm to fertilize a normal egg and for the result to be a miscarriage. However, that event doesn't mean anything about your partner's sperm in general. Particularly if you have two healthy kids, the odds are high that this is, really, just a fluke.

I can completely understand that you would be nervous. I think that problems that would lead to miscarriage can come from either the egg or the sperm. I would ask your doctor and see if they can give you any more information. Good luck to you!

I was just at a RE and asked this very question. I too, recently had 2 back to back m/c. Dh and I have 1 child and Dh has a child from a previous marriage.

RE said not to even bother with a SA. That since it's know that he can father dc, chances are great that he can father more. Like pp said, every guy shots some duds, but that to be able to fertilize an egg, means that there's enough good ones.


All my bloodwork is normal as well. I was basically told my issue is due to my age.

Sounds like you've gotten some really good information from the knowledgeable women here.

Just out of curiosity - what blood work-ups did they do?

I'm wondering if you've had a thrombophilia panel, been checked for thyroid antibodies and had an hsg (not a blood test)?

Thanks you all gave me some awesome advice.

My DR actually is fairly confident that its all just bad luck but I feel otherwise
