Miscarriage - Possibly a problem with sperm?

[Annie421]

Hi,

Sadly my sister miscarried her baby yesterday, she was 11 weeks. She has 3 other children which she had when she was vey young, these pregnancies were all very healthy and she has never miscarried before. She has been with her partner ( not the father of the other 3 children ) for quiet a while and they decided to try for a baby, my sister is 34 and her partner is 52.

Her partner has never had any children but he has got two previous partners pregnant ( this was when he was much younger), one miscarried at 10 weeks and another one miscarried at 11 weeks - could there be any link to this as my sister has miscarried at 11 weeks also? - is it possible for a man to have something wrong with his sperm that would cause a baby not to form properly? Would his age have anything to do with the quality of his sperm?

Many Thanks

First of all I'm sorry this has happened to your sister.

Her miscarriage is probably just down to chance. A huge number of pregnancies end in miscarriage unfortunately.

There is a theory that morphology can have an effect on pregnancy, but only when coupled with a woman with what a 'non fussy uterus'

Basically a 'normal' uterus would reject and abnormal pregnancy (the kind that would be the result of being fertilised by poor sperm) but a non fussy uterus would let that pg implant. Even though the pg implants it cannot continue to grow and a miscarriage results.

This is just a theory that some specialists have and routine sperm tests are not offered when tests are done for recurrent miscarriage.

The chances of this being a problem your sister has is very small.

I hope she and her dh have better luck in any future pregnancies.
