And quotes:
Male infertility. Male infertility increases with the man’s age. Men older than 35 are twice as likely to be infertile (defined as the inability to initiate a pregnancy within 12 months) compared to men younger than 25.

Birth Defects. As with advanced maternal age, advanced paternal age is associated with an increased incidence of birth defects due to decreased genetic quality of sperm. Men 40 and older are nearly six times more likely to have offspring with autism than men younger than 30, even after controlling for maternal age and other variables. Other defects associated with elevated paternal age include schizophrenia, Down syndrome and genetic abnormalities.

As we all know, it’s common and often celebrated for men to father children over 35.

In truth, there are a lot of factors to consider here. older parents can make better parents in many ways, as they tend to be more stable financially and emotionally. And there’s nothing wrong with looking out for ourselves AND our babies: Wouldn’t our mothers and fathers want us to? ;] In short, let’s think carefully about our knee-jerk responses to older moms (and dads). Yes, there are more risks, but there can be benefits too.

i am 42 and am currently pregnant with number 2, i already have a daughter who is 7. We didnt try and didnt use any other costly method, it all happened naturally. To the 27 year old, there have been many cases of downs syndrome in the 20 somethings as they are hardly ever recommended to do any further testing… i have known many women under 30 who have had many problems conceiving…so please dont judge anyone who is blessed to be pregnant naturally or other wise no matter how old they are!!

I was 2 days away from my 40th birthday when I gave birth to my first son (no problem getting pregnant) and I was 43 just 4 days when I gave birth to my second son (no problems getting pregnant again). I know a lot of women who have had trouble getting pregnant so I consider us fortunate.

Here’s something that is interesting. I have been told by my doctor that my chances of having a child with a genetic abnormality are just as good as a 20 year-old. Reason being (and I hope I explain this correctly)is that my eggs were made when I was in my own mother’s womb so if there were any genetic abnormalities they would have been there since then. Some other things that can cause other abnormalities is that my eggs are now over 40 years old.

90% of eggs are abnormal at 42. I have a hard time believing that as well. I’ve seen so many women after age 40 get pregnant – by accident no less. I’m not saying that it’s easy, but criticizing women that have babies after 40 by saying it should be a last resort? That’s horrible.

Pencils –

I’ve seen you post that stat before, and that is nowhere near the math I am familiar with. A link from an expert who appeared on the Oprah show, with quote:

http://www.oprah.com/tows/pastshows/tows_2002/tows_past_20020501_c.jhtml

“She also says that by the time a woman is 42 years old, ninety percent of her eggs are abnormal, and there is only an 8 percent chance of having a baby without donor eggs.”

Now maybe that’s too dire, but there’s no way I’m believing that half of all 41-year-old women can get pregnant without intervention. You’d be lucky to get to that figure with use of fertility drugs and mothers’-eggs IVF. Where did you get your info that placed the number so high?

I’m glad that you personally had such an easy time, but I think it’s a disservice to women to make it seem more likely than the data truly shows it to be.

I had never heard that half of women over 40 could get pregnant with no assistance, but I have read that after 40 your chance of getting pregnant spontaneously is half what it was at 20. The fact is that after 35 you are considered “advanced maternal age” and your fertility drops significantly. I know several women that had babies in their early forties, some with help, some without. But I would guess that most of the women on this list had some kind of help.

I’m 41 years old, and 29 weeks pregnant with my first child. I got pregnant the first month we tried. Half of women my age can get pregnant with no assistance. Yes, there are higher risks of conditions like Downs, but they’re still just risks. As long as you are in good health, there’s nothing wrong with having a child past 35 or even 40. And if you have difficulty getting pregnant, reproductive technologies are getting better and better. I don’t think it’s a great idea to put off childbearing if you don’t have a good reason, but I don’t think there are many women who do. Most older mothers become so because of reasons like mine–I didn’t meet The One until a month before my 38th birthday, and I never wanted to be a single mother. And I’m lucky that I turned out to be still very fertile. From what I’ve read, if your mother went through menopause late, it’s likely that you will also, and it’s also likely that you will remain fertile longer. My mom didn’t start menopause until she was 57.

So, if you want to be a mother someday and it’s not a good time now, be heartened! It can and does happen for women in their late 30s and 40s, and not just to celebrities. I have a friend who recently had her first baby at age 44, using an egg donor. He’s a wonderful, sweet child. Yes, it was expensive, but she thinks it’s the best money she ever spent.

half those baby were convived via fecondation in vitro. What you probably sould motion is that this kind of medecin cost a lot of money. For the women who have the money it’s great, they can wait, but for those who don’t well, this list can make them think that they have all the time they need and that having a baby in your late 40’s is possible. But it’s not. My dad had me when he was 45( my mom was 31 so it’s not really the same but still). He is now 62 and is soon going to stop his work. I can’t imagine having my dad around all the time while some of my friends’s grandparents still work! Having a kid that late is just selfish. You really want to be 70 when your kid is 20?!
Jane seymour had a twins when she was almost 45 but she had her daughter when she was 30 and her son a couple of years later, so it’s not the same. She remarried and wanted another kid, she had twins.

I’m a 27 year old mom with my 2nd on the way and I don’t like seeing this! Let’s not get too excited… Hollywood makes it seem so easy and safe to have babies in your 40’s, but the truth is, it’s not ideal for YOUR BABY’s health and should be a last resort. There are a lot of risks for the mother as well, and us “average chicks” probably can’t afford the treatments these celebrities undergo.

What I can’t believe is that we still don’t know what Helena Bonham Carter, Holly Hunter and Helen Fielding named their kids!
