Men have a biological clock too. Here’s what’s more likely when dads are over 50

<div class="theconversation-article-body"><em><a href="https://theconversation.com/profiles/karin-hammarberg-113096">Karin Hammarberg</a>, <a href="https://theconversation.com/institutions/monash-university-1065">Monash University</a></em></p> <p>We hear a lot about women’s biological clock and how age affects the chance of pregnancy.</p> <p><a href="https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2821811#google_vignette">New research shows</a> men’s fertility is also affected by age. When dads are over 50, the risk of pregnancy complications increases.</p> <p>Data from more than 46 million births in the <a href="https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2821811#google_vignette">United States</a> between 2011 and 2022 compared fathers in their 30s with fathers in their 50s.</p> <p>While taking into account the age of the mother and other factors known to affect pregnancy outcomes, the researchers found every ten-year increase in paternal age was linked to more complications.</p> <p>The researchers found that compared to couples where the father was aged 30–39, for couples where the dad was in his 50s, there was a:</p> <ul> <li>16% increased risk of preterm birth</li> <li>14% increased risk of low birth weight</li> <li>13% increase in gestational diabetes.</li> </ul> <p>The older fathers were also twice as likely to have used assisted reproductive technology, including IVF, to conceive than their younger counterparts.</p> <h2>Dads are getting older</h2> <p>In this <a href="https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2821811#google_vignette">US study</a>, the mean age of all fathers increased from 30.8 years in 2011 to 32.1 years in 2022.</p> <p>In that same period, the proportion of men aged 50 years or older fathering a child increased from 1.1% to 1.3%.</p> <p>We don’t know the proportion of men over 50 years who father children in Australia, but data shows the average age of fathers has increased.</p> <p>In 1975 the <a href="https://www.abs.gov.au/statistics/people/population/births-australia/latest-release">median age of Australian dads</a> was 28.6 years. This jumped to 33.7 years in 2022.</p> <h2>How male age affects getting pregnant</h2> <p>As we know from <a href="https://www.businessinsider.com/celebrities-dads-first-time-over-age-50#when-he-was-54-simon-cowell-and-girlfriend-lauren-silverman-became-parents-to-their-son-eric-7">media reports</a> of celebrity dads, men produce sperm from puberty throughout life and can father children well into old age.</p> <p>However, there is a noticeable decline in <a href="https://www.fertstert.org/article/S0015-0282(18)30269-3/fulltext">sperm quality</a> from about age 40.</p> <p>Female partners of older men take longer to achieve pregnancy than those with younger partners.</p> <p>A study of the effect of male age on <a href="https://www.fertstert.org/article/S0015-0282(03)00366-2/fulltext">time to pregnancy</a> showed women with male partners aged 45 or older were almost five times more likely to take more than a year to conceive compared to those with partners aged 25 or under. More than three quarters (76.8%) of men under the age of 25 years impregnated their female partners within six months, compared with just over half (52.9%) of men over the age of 45.</p> <p>Pooled data from ten studies showed that partners of older men are also more likely to experience miscarriage. Compared to couples where the male was aged 25 to 29 years, <a href="https://pubmed.ncbi.nlm.nih.gov/32358607/">paternal age over 45 years</a> increased the risk of miscarriage by 43%.</p> <h2>Older men are more likely to need IVF</h2> <p>Outcomes of assisted reproductive technology, such as IVF, are also influenced by the age of the male partner.</p> <p>A <a href="https://doi.org/10.1016/j.rbmo.2022.03.031">review of studies</a> in couples using assisted reproductive technologies found paternal age under 40 years reduced the risk of miscarriage by about 25% compared to couples with men aged over 40.</p> <p>Having a male under 40 years also almost doubled the chance of a live birth per treatment cycle. With a man over 40, 17.6% of treatment rounds resulted in a live birth, compared to 28.4% when the male was under 40.</p> <h2>How does male age affect the health outcomes of children?</h2> <p>As a result of age-related changes in sperm DNA, the children of older fathers have increased risk of <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9957550/">a number of conditions</a>. Autism, schizophrenia, bipolar disorders and leukaemia have been linked to the father’s advanced years.</p> <p>A <a href="https://www.fertstert.org/article/S0015-0282(22)01979-3/fulltext">review of studies</a> assessing the impact of advanced paternal age reported that children of older fathers have increased rates of psychiatric disease and behavioural impairments.</p> <p>But while the increased risk of adverse health outcomes linked to older paternal age is real, the magnitude of <a href="https://pubmed.ncbi.nlm.nih.gov/29471389/">the effect is modest</a>. It’s important to remember that an increase in a very small risk is still a small risk and most children of older fathers are born healthy and develop well.</p> <h2>Improving your health can improve your fertility</h2> <p>In addition to the effects of older age, some chronic conditions that affect fertility and reproductive outcomes become more common as men get older. They include <a href="https://www.fertstert.org/article/S0015-0282(23)01935-0/fulltext">obesity and diabetes</a> which affect sperm quality by lowering testosterone levels.</p> <p>While we can’t change our age, some lifestyle factors that increase the risk of pregnancy complications and reduce fertility, can be tackled. They include:</p> <ul> <li><a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4639396/">smoking</a></li> <li>recreational <a href="https://onlinelibrary.wiley.com/doi/pdf/10.1002/tre.414">drug taking</a></li> <li><a href="https://onlinelibrary.wiley.com/doi/pdf/10.1002/tre.414">anabolic steroid</a> use</li> <li>heavy <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5504800/">alcohol consumption</a>.</li> </ul> <h2>Get the facts about the male biological clock</h2> <p>Research shows <a href="https://academic.oup.com/humupd/article/23/4/458/3065332?login=false">men want children</a> as much as women do. And most men want at least two children.</p> <p>Yet most men <a href="https://academic.oup.com/humupd/article/23/4/458/3065332?login=false">lack knowledge</a> about the limitations of female and male fertility and overestimate the chance of getting pregnant, with and without assisted reproductive technologies.</p> <p>We need better public education, starting at school, to improve awareness of the impact of male and female age on reproductive outcomes and help people have healthy babies.</p> <p>For men wanting to improve their chance of conceiving, the government-funded sites <a href="https://healthymale.org.au/">Healthy Male</a> and <a href="https://www.yourfertility.org.au/">Your Fertility</a> are a good place to start.

James Bond is more than a (sexist) secret agent. He is a fertility god, a Dionysus of the modern era

<p>James Bond is more than a (sexist) secret agent. He is a fertility god, a Dionysus of the modern era</p> <p>“History isn’t kind to people who play God,” quips James Bond to supervillain Safin in the trailer for No Time to Die.</p> <p>The film’s release has been delayed yet again, to April 2021. It will mark Daniel Craig’s swansong as 007 and speculation continues as to who will be the next Bond. Will it be Idris Elba, Tom Hardy or perhaps a woman?</p> <p>Bond has long been criticised for his sexist attitudes, with even Judi Dench’s M in GoldenEye (1995) dubbing him a “sexist, misogynist dinosaur” . But what if we view him through the prism of Greek mythology? Is Bond, in fact, a contemporary incarnation of Dionysus, the god of wine, pleasure and fertility?</p> <p>In Greek mythology, the gods punish mortals for the sin of hubris. In our pop-culture pantheon, Bond is a deity.</p> <p>Dionysus travelled throughout the ancient world, sometimes by boat in the Aegean islands, sometimes in a winged chariot. Bond also circumnavigates the globe, equally at home on yachts or in helicopters. But his chariot of choice is an Aston Martin.</p> <p>Its logo? A pair of wings.</p> <p><strong>Secrets of wine – and martinis</strong><br />Wherever Dionysus went he initiated his followers in the secrets of wine-making. Wherever Bond goes he initiates the mixologist in the secrets of making the perfect Vesper martini.</p> <p>In Ian Fleming’s Diamonds are Forever (1956), Bond tells the bartender to combine three measures of Gordon’s gin, one of vodka and half a measure of Kina Lillet with a thick slice of lemon peel and poured into a deep champagne goblet. In Casino Royale (2006), he adds the martini must be shaken “until it’s ice cold.”</p> <p>Unlike mortals, Bond’s prodigious consumption of alcohol does him no harm, indeed he is hailed as “the best shot in the Secret Service.”</p> <p>In a study of the novels published in the British Medical Journal in 2013, researchers estimated Bond consumed an average of 92 units of alcohol per week with a maximum daily intake peaking at 49.8 units.</p> <p>There were days when Bond abstained – 12.5 out of a total 87.5 days – but mostly because he was being held prisoner.</p> <p><strong>Weapons of disguise</strong><br />Dionysus carries a thyrsus: a sacred pinecone-tipped staff wreathed in vines. The thyrus is a phallic symbol, sometimes displayed with a kantharos wine cup, denoting female sexuality.</p> <p>The union of the two created a powerful representation of fertility and rebirth. Dionysus also turned his thyrsus into a dangerous weapon by secreting an iron tip in its point.</p> <p>As a secret agent, Bond conceals his Walther PPK pistol in a hidden holster, but one of his most lethal weapons is disguised as a cigarette – a potent symbol of sexual union in cinema, where smoking a cigarette signifies the completion of copulation.</p> <p>In You Only Live Twice (1967) the villain makes the fatal mistake of allowing Bond “one last fag.” It turns out to be tipped with a rocket-propelled bullet, proving that cigarettes aren’t just lethal for smokers.</p> <p><strong>Gods of possession</strong><br />Dionysus was deeply attractive to his female followers, Maenads, who would drink themselves into a frenzy to be possessed by the god. Likewise, Bond is pursued by a bevy of beautiful women – Pussy Galore, Plenty O’Toole and Honey Rider – panting to be possessed.</p> <p>As with the Maenads, devotion to Bond comes with its perils. In Live and Let Die (1973), Bond girl, Solitaire loses her psychic powers after a close encounter of the passionate kind with Bond and becomes a target for heroin baron, Dr Kananga.</p> <p>In Goldfinger (1964), Jill Masterton is punished by the eponymous villain for betraying him to Bond, dying of skin suffocation when he covers her in gold paint.</p> <p>This puts a new spin on the Midas myth in which Dionysus granted the king’s wish to be blessed with the golden touch, only to discover that it is a curse making it impossible to eat or even embrace his daughter without turning her into metal.</p> <p><strong>Ecstasy and death</strong><br />In ancient Greece, the number seven was sacred and composed of the number three (the heavenly male) and the number four (the heavenly female). Bond’s number in the secret service – Agent 007 – is thus the perfect number to represent a modern-day fertility god.</p> <p>Like Dionysus who is depicted in a number of forms which range from an older, bearded god to a long-haired youth, Bond has appeared in a variety of guises from the debonair David Niven to the strapping Daniel Craig.</p> <p>Yet regardless of his age and physique, Bond’s dual Dionysian nature brings either divine ecstasy in bed, or brutal death to his foes.</p> <p>Dionysus almost dies before he is born but his father Zeus saves him. Later he returns from the dead after he is dismembered by the Titans.</p> <p>Bond says, “You only live twice: once when you are born and once when you look death in the face.”</p> <p>Like Dionysus, Bond is resurrected in Skyfall (2012) after he is accidentally shot by Moneypenny. The bullet penetrates his body causing him to fall off a train and into a waterfall where he sinks to the bottom. But Bond is immortal. He returns to save another day.</p> <p>When it finally reaches cinemas, No Time to Die will be the last hurrah for Craig, but gods do not die. Bond will live on.</p> <p><em>Written by Nicole Lenoir-Jourdan. This article first appeared on <a href="https://theconversation.com/james-bond-is-more-than-a-sexist-secret-agent-he-is-a-fertility-god-a-dionysus-of-the-modern-era-131040">The Conversation</a>.</em></p>

Deb Knight opens up about unexpected dilemma after IVF

<p>When Channel Nine journalist Deb Knight and her husband Lindsay Dunbar turned to IVF to have kids, they were faced with a rather unexpected decision afterwards: what to do with the one leftover embryo?</p> <p>Knight, who went through two years and 11 cycles of IVF to have son Darcy and daughter Elsa, eight and seven respectively (21-month-old Audrey was a “lovely surprise”), visited the <span>Today </span>show yesterday to talk about the rarely-discussed dilemma faced by thousands of parents around the country.</p> <blockquote style="background: #FFF; border: 0; border-radius: 3px; box-shadow: 0 0 1px 0 rgba(0,0,0,0.5),0 1px 10px 0 rgba(0,0,0,0.15); margin: 1px; max-width: 658px; padding: 0; width: calc(100% - 2px);" class="instagram-media"> <div style="padding: 8px;"> <div style="background: #F8F8F8; line-height: 0; margin-top: 40px; padding: 50.0% 0; text-align: center; width: 100%;"> <div style="background: url(data:image/png; base64,ivborw0kggoaaaansuheugaaacwaaaascamaaaapwqozaaaabgdbtueaalgpc/xhbqaaaafzukdcak7ohokaaaamuexurczmzpf399fx1+bm5mzy9amaaadisurbvdjlvzxbesmgces5/p8/t9furvcrmu73jwlzosgsiizurcjo/ad+eqjjb4hv8bft+idpqocx1wjosbfhh2xssxeiyn3uli/6mnree07uiwjev8ueowds88ly97kqytlijkktuybbruayvh5wohixmpi5we58ek028czwyuqdlkpg1bkb4nnm+veanfhqn1k4+gpt6ugqcvu2h2ovuif/gwufyy8owepdyzsa3avcqpvovvzzz2vtnn2wu8qzvjddeto90gsy9mvlqtgysy231mxry6i2ggqjrty0l8fxcxfcbbhwrsyyaaaaaelftksuqmcc); display: block; height: 44px; margin: 0 auto -44px; position: relative; top: -22px; width: 44px;"></div> </div> <p style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; line-height: 17px; margin-bottom: 0; margin-top: 8px; overflow: hidden; padding: 8px 0 7px; text-align: center; text-overflow: ellipsis; white-space: nowrap;"><a style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: normal; line-height: 17px; text-decoration: none;" href="https://www.instagram.com/p/BTMHAyyAL3M/" target="_blank">A post shared by Deborah Knight (@deborah_knight)</a> on Apr 22, 2017 at 6:24am PDT</p> </div> </blockquote> <p>There are four common options for parents with leftover embryos – using them, donating them to another couple, donating them to medical research, or discarding them. After much thought, Knight and Dunbar decided to donate their “spare” embryo to medical research.</p> <p>“If I had a friend or family member who was having trouble conceiving, that would be a different scenario,” the 45-year-old explained. “Donating to a stranger ... you have to connect with that person. You have to then go down the process of giving up all of your rights to that potential child. There are all sorts of legal issues to consider.”</p> <p>According to IVF specialist Dr Rick Gordon, only around one in 100 couples who consider donating their remaining embryo(s) to a couple struggling with their fertility actually go through with it.</p> <p>“When the penny drops that it's their own child out there – a sibling to their own children – that's a different kettle of fish,” he said. "We’re talking cells here, but to people's brains, these are potential human beings.”</p> <p><span>Today</span> show co-host Georgie Gardner praised Knight for speaking so openly about a topic so rarely discussed. “I appreciate so much you being so candid and sharing your experience.”</p> <p>Knight replied that she only hoped her story would help others grapple with the difficult decision. “Hopefully it helps others going through the process to know that they’re not alone.”</p> <p><em>Image credit: Deb Knight/Instagram.</em></p>

Australia’s fertility rate drops to 10-year low

<p>Australia’s fertility rate has fallen to the lowest level in 10 years.</p><p>The Australian Bureau of Statistics has found that the national fertility rate has dropped to 1.8 children per woman, down from roughly 1.88 children per woman. Interestingly, the last time the fertility rate was this low the government introduced a baby bonus to boost population growth.</p><p>299,700 births were registered in Australia in 2014, down from 308,100 in 2013, with the biggest difference coming in New South Wales which say a 9.3 per cent decline compared to 2013.</p><p>AJ Lanyon, the regional director at the ABS, told The Sydney Morning Herald, “This rate has been declining since 2008, though not reaching the low recorded in 2001. There was a strong pattern in our major cities where the highest birth rates were in outer suburbs and very low rates in the inner city. These inner city areas had high proportions of younger people, but few babies.”</p><p>With the baby-boomer generation ageing this fertility rate causes potential population replacement problems. If you’ve got visions of grandchildren it might be time for some gentle encouragement.</p><p><strong>Related links:</strong></p><p><a href="/news/news/2015/10/air-piano-baby-video/"><span style="text-decoration: underline;"><em><strong>Baby plays air piano</strong></em></span></a></p><p><a href="/news/news/2015/10/jamie-oliver-cooking-with-family/"><span style="text-decoration: underline;"><em><strong>Jamie Oliver’s son interrupts cooking show to “go toilet”</strong></em></span></a></p><p><a href="/news/news/2015/10/cute-baby-meets-pug-puppies/"><span style="text-decoration: underline;"><em><strong>Baby hysterical when he meets pugs for first time</strong></em></span></a></p>
