Can a old man get you pregnant
When it comes to infertility, women get a lot of the blame. What causes male fertility decline? And how is it similar—and different—from the fertility decline women experience? This is known as reduced egg quality. Because both egg count and egg quality decline with age, it makes sense that—while there are other causes of female infertility—age is the most influential factor when it comes to female fertility.

Fertility and Men Making Babies Over 50
So, I challenge any woman in this group not to feel just a teensy bit of schadenfreude at the increasing discussion of aging sperm and its effects on childbearing. Of course, for this to happen there has to be something to all of this concern. So, are older sperm really worse? Worries about aging sperm — or, more accurately, sperm from aging men — are the same as the concerns about aging eggs: decrease in fertility, and increase in genetic problems and psychiatric and behavior disorders among offspring.
The primary issues in the latter category are autism and attention deficit hyperactivity disorder ADHD. You might think that it would be easy to figure out how sperm quality declines by comparing pregnancy rates for the partners of older and younger men. And, in fact, some scientific papers do this. But they have a central problem: Older men tend to be matched with older women. It turns out this problem is surmountable with a simple trick: Observe cases where couples are using donor eggs.
Studies that do this — here is one nice review in the journal Fertility and Sterility — tend to find that while semen volume and, hence, sperm count does decline with age, there is little overall impact on reproductive success the ability of the sperm to penetrate the egg, fertilize it, etc.
So more sex may be necessary. The evidence on autism and other behavioral disorders appears less reassuring. They concluded that relative to children born to to years-old fathers, those with fathers aged 30 to 39 were 1.
The studies used in the meta-analysis were all pretty consistent. They did not all find the same size effect, but virtually all pointed to increased risk of autism with increased paternal age.
We would clearly prefer to have a study that compared children born to the same man at different times in his life. This fixes a few problems. Second, we avoid any concern that some kinds of dads are more likely to have their kids evaluated for autism or other disorders. Last year, the journal JAMA Psychiatry published a study about paternal age that included this design, and, to put it mildly, the results were alarming.
The study used a full census of births in Sweden from to and merged together information on parent age, siblings, other family members, psychiatric diagnoses, grades in school, and on and on. The researchers ran regressions where they effectively compared children born to the same father at different times in his life, and they reported enormous changes in psychiatric problems.
They found big effects on autism: Children born to men over 45 were 3. But even more striking, and notable, were the effects on ADHD diagnosis: Relative to children born to men 20 to 24 years old, those who were born to men over 45 were 13 times more likely to be diagnosed with ADHD. Even children born to men 30 to 34 were more than three times as likely to be diagnosed with ADHD as those born to the youngest father group. This is enough to send a lot of men I know straight to the sperm freezer.
The authors actually ran three analyses. First, they looked at the raw data and asked, on average, are children born to older fathers more likely to have ADHD? Second, they controlled for some demographics, such as education and income, and maternal age. In the first analysis using raw data, older men do not appear to be more likely to have children with ADHD.
One theory for this gap in results is, of course, that the final analysis is the most accurate because it examines children under near ideal conditions: They were born to the same father at different times in his life. Consider a dad with two children, born four years apart. A basic fixed-effects model would ask whether the older child is less likely to have ADHD than the younger, and then attribute any observed difference to paternal age.
Running this basic analysis would have the same problem with maternal age that we discussed earlier. Because mothers often age along with fathers within a family, if we analyzed sibling pairs with the same mother and the same father, it would be impossible to separate the effects of maternal and paternal age.
This paper does claim to separate these effects. The data includes half-siblings — children who share a father but not a mother. That means the huge positive effect seen in the chart above essentially tells us that a later-born child of a father who has multiple kids with multiple partners is more likely to be diagnosed with ADHD.
In the paper, this difference is attributed to paternal age. Why push so deeply into the statistics here? Seeing what the data is really saying lets us think a little more about what else might be happening. Now that we know the effects are driven by differences across half-siblings, we can start asking what else — beyond paternal age — might be driving the difference. Most obviously, we may wonder whether being a child in a fluid family situation could itself have an impact on ADHD risk as other studies have found.
And this makes it more likely that the results they saw were just due to chance. Yes, there is some possibility that it matters. I also confirmed this in personal communication with the authors. Sorry, your blog cannot share posts by email.
Pregnant At 53: Older Pregnancy Happened To Me
So, I challenge any woman in this group not to feel just a teensy bit of schadenfreude at the increasing discussion of aging sperm and its effects on childbearing. Of course, for this to happen there has to be something to all of this concern. So, are older sperm really worse?
The world's oldest new dad, who, at the reported age of 96, just fathered a baby boy in India, says he's done having kids. But if he wanted to break his record again in a couple years, would biology allow it? Though sperm production does usually keep up until a man's dying day, it's a misconception that "biological clocks" are only of concern to women. The effects of aging on fertility have been studied far less in men than in women, but research shows that both volume and quality of semen generally fall off as a man gets older.
Men who want to have kids after 50: know the risks
And many times, that love turns into welcoming a baby together. While some couples able to hole up abroad before their baby comes, other moms and their much-older men likely have a harder time navigating early parenthood together. But the truth is, between getting pregnant in the first place to introducing baby to your friends and family, there are many struggles that come with having a baby with a much older man - here are twenty of them. At the same time, women with an older partner- a man who was five years or more her senior- had at least a 15 percent lower chance of getting pregnant than women who had same-age or close-in-age partners. That means just falling pregnant with an older partner may prove tricky. Still, pregnancy rates for post-reversal couples can vary between 30 and 70 percent, likely due to other factors than just sperm health and motility. Very Well Family noted another medical roadblock to couples with an older man falling pregnant- the potential for genetic defects in a developing embryo. Plus, older men are more likely to pass on genetic problems to their children.

Male fertility does change with age. You might get the impression that age only matters in female fertility. While the change in fertility is more drastic in women, men have biological clocks, too. The study looked at everything a semen analysis would, including how often they had sex.

While there is plenty of information readily available about the potential risks of women having children after age 35, there is less talk and information at hand about the risks and challenges for men deciding to have children later in life. In the Western world, more and more men are having children over the age of 50, thanks to increased life expectancy, later marriages and other reasons.

People are becoming parents at ever-increasing ages, a trend that can have implications for the health of the pregnancy, the babies and the women who birth them. But while most women know that reproductive risks to themselves and their babies rise as they get older, few men past 40 realize that their advancing years may also confer a risk.
Age and Fertility (booklet)
Why age matters for men and women who want to have a family. We all know someone who had a healthy baby in their late 30s or early 40s. But of all people who try for a baby at a later age, many will not have the baby they hoped to have. Across a population, women younger than 35 and men younger than 40 have a better chance of having a child than people who are older. This is true for natural pregnancies and for pregnancies conceived through assisted reproductive treatments such as IVF in-vitro fertilisation. A woman is born with all the eggs she will ever have. This information can be difficult for women who, for whatever reason, are not ready in their 20s or early 30s to start a family. Men younger than 40 have a better chance of fathering a child than those older than

Older fathers put health of partners, unborn children at risk
Most men know that women's fertility declines after the age of 35, but many men are not aware that their age can affect their ability to become a parent, too. While less is known about male fertility and age, there is evidence that the older a man becomes, the more his fertility diminishes. It is not impossible for older men to father children, in fact, many men remain fertile until they are But conceiving does become more difficult and complicated as you age.
