Quote: Around half of all pregnancies in women over 40 end in miscarriage.
Quote: Patients over 40 may have a miscarriage rate as high as 50%. Miscarriage rates for 40-year-old women are about twice that for 20-year-old women.
Quote: Generally, the rate of infertility in women over 40 is 30% greater than in younger women, while the miscarriage rate in women over 40 is about 50% using ART
I was just looking on the BFP [Big Fat Positive on a pregnancy test] post on FertilityFriends.com and thought the following numbers might be helpful:
May - 28 BFP - 13 losses
June - 7 BFP - 2 losses
July - 13 BFP - 7 losses
August - 12 BFP - 7 losses
Sept - 15 BFP - 7 losses
October 21 BFP - 6 losses
November 13 BFP - 3 losses
Total: 109 BFP in 7 months, with 45 losses
So the ratio is just over 60% success! And these are women who have struggled to get pregnant, so they often have a higher risk. The average 40 year old woman will have a much higher success rate!
