The great age divide Medically speaking, pregnancy is divided into two halves: before 35 and after. As soon as you cross that age barrier, your pregnancy is considered higher risk and your obstetrician will probably recommend tests that wouldn't be suggested to someone younger, such as amniocentesis. That's because older women are more likely to have babies with birth defects or chromosomal abnormalities. They are also more likely to have chronic health problems such as adult-onset diabetes, high blood pressure, heart and kidney problems, and autoimmune diseases that can complicate pregnancy and delivery. Some statistics: Getting pregnant Conceiving is easier before 35. Only 7% of women aged 20 to 29 are infertile, and 15% of those aged 30 to 34. After that, infertility rates rise as problems with ovulation, egg quality and Fallopian-tube health become more common. From ages 35 to 39, 22% of women are infertile; and 29% of women aged 40 to 44. Staying pregnant Before 35, the miscarriage rate is about 1 in 4. At 35, the rate rises to 1 in 3; it's 1 in 2 after 40; and more than 50% after 45. Labour, delivery and recovery Because the risk of foetal distress increases with maternal age, Caesarean-section rates also rise, from 20,5% before age 35 to 30,4% after. In addition, pregnancies (especially multiple births) conceived with the help of assisted reproductive technology (more common among older women) are more likely to require C-sections. After 35, instrument-assisted deliveries (forceps or suction) also increase, and recovery from childbirth takes longer. Episiotomies aren't age-related but are more likely with instrument deliveries. The baby Reports show that babies born to mothers older than 35 are 20–40% more likely to have a low birth weight, 20% more likely to be born prematurely and 20% more likely to be a twin or triplet. Babies born to mothers who are 40 have a 1 in 66 chance of chromosomal problems; the rate is 1 in 21 for the child of a 45-year-old. Specifically, the risk for Down's syndrome is 1 in 1667 at age 20, 1 in 952 at 30 and 1 in 106 at 40.

I think what Idma was trying to say is:

Producing a pregnancy can be more difficult for older men and research is starting to show that there may be some increased risks for the baby, including a higher incidence of autism, schizophrenia and a type of dwarfism.

quote:

What is the risk of birth defects in babies of women over 35? The risk of bearing a child with certain chromosomal disorders increases as a woman ages. The most common of these disorders is Down syndrome, a combination of mental retardation and physical abnormalities caused by the presence of an extra chromosome 21 (humans have 23 pairs of chromosomes). At age 25, a woman has about a 1-in-1,250 chance of having a baby with Down syndrome; at age 30, a 1-in-1,000 chance; at age 35, a 1-in-400 chance; at age 40, a 1-in-100 chance; and at 45, a 1-in-30 chance

quote:

While the general population of childbearing women has a 3% chance of delivering a child with a birth defect, after age 40 this risk rises to between 6% and 8%. The likelihood of having a baby with Down's syndrome is approximately 1 in 365 at the age of 35. This number increases to 1 in 100 by the age of 40 and up to 1 in 40 at the age of 45.

quote:

====================================================================== At what age does this curve of defects in children born to middle-aged mothers begin to sharply increase? ====================================================================== Rather alarmingly, there is a noticeable increase in non-chromosomal fetal malformations starting around age 25. At 35, there are markedly increased risks, since chromosomal abnormalities (including Down Syndrome) spike dramatically around this time in middle age. Another big jump in instances of birth defects comes with mothers who are 40 and older. "Researchers conducted this study to examine the effect of maternal age on incidence of non-chromosomal fetal malformations. Malformations detected at birth or in the newborn nursery were catalogued prospectively for 102,728 pregnancies, including abortions, stillbirths, and live births. Clearly chromosomal defects increase with age and this was confirmed in the present study by karyotyping. After excluding infants with chromosomal abnormalities, the incidence of structurally malformed infants also increased significantly in women > 25 years of age. The additional age-related risk of non-chromosomal malformations was approximately 1% in women 35 years of age or older. The odds ration for cardiac defects was 3.95 (about times greater) in infants of women >40 years as compared to women 20-24 years of age. The risks of clubfoot and diaphragmatic hernia also increased as maternal age increased. It was concluded that advanced maternal age >25 years was associated with a significantly increased risk of fetuses having congenital malformations not caused by aneuploidy."

Kris, I didn't say that this is specifically about AFTER 35. It is common knowledge that as we age, our cells degenerate. Not only does the fertility rate begin to significantly drop after the age of THIRTY, but birth defects become more evident as well. Obviously the older the woman is, the more likely her child is to have a defect of some sort.


Read all of the quotes. Here is one that you must have skipped:

quote:

Do some research on reproductive senescence. Nevermind. Just read this:

quote:

SUMMARY: As women age, egg dysfunction increases, with meiotic nondisjunction, embryonic arrest, apoptosis, and miscarriage. Egg dysfunction results from two 'hits' - reduced formation of chiasmata during fetal oogenesis, and accumulation of reactive oxygen damage during the prolonged interval until ovulation. Late exit from a production line during oogenesis presumably contributes to the first hit. The later insult also involves meiotic spindle abnormalities. Telomeres, repetitive sequences of DNA, cap chromosome ends and dissipate during divisions. Oocytes do not divide, but oogonia do, and telomerase, the enzyme responsible for maintaining telomere length, is inefficient, and remains inactive in oocytes and embryos until blastocyst stage. Reactive oxygen also shortens telomeres, so the prolonged interval between birth and ovulation would further shorten telomeres from chronic exposure to reactive oxygen. In support of this theory, experimental shortening of telomeres in mice produced a phenotype similar to reproductive aging in women, with abnormal chiasmata, spindles, cell cycles, apoptosis, and genomic instability, and telomere length in human eggs.

All I am saying is that the older a woman gets, the higher the risk is of her child having a defect. So, in theory, having a child at the age of 25 is a lot more healthy than having a child at the age of 30.

I guess I'm lucky then - my parents were over 40.

(Yes, I know exactly what that means)

honestly, the whole biological clock scares do nothing for me if I feel that by 25-27 I haven't reached the time when I can honestly say I want a child, I will wait, even if I'll be waiting till I'm 30

I thought this was all common knowledge? Its concerning that some people dont! Anyways I wont be having any babies till I am 30-35, but pushing that 40 line is definately a risk.

I thought so too! It's not a stupid fucking myth that was made up to "scare" people. It's a scientific FACT. Maybe your children won't have any problems, but that can't be said for all mothers who decide to conceive at an older age.

*sigh*
