Does my age affect my fertility?

(Harris 2019, NICE 2013)

(Harris 2019)

Sperm quality tends to decrease with age. In particular, the shape (morphology) and movement (motility) of your sperm are both likely to deteriorate as you get older, making it more difficult for them to fertilise an egg (Harris et al 2011, Harris 2019) . You may also produce less sperm as you age. (Harris 2019) . You may also produce less sperm as you age. From about the age of 40, your testosterone levels are likely to decrease (Harris et al 2011) .

What can I do to protect my fertility as I age?

Eat healthily . If you’re very overweight, losing a few pounds is likely to make it easier for you to conceive (NICE 2013, NHS 2017a) . Some studies suggest that a diet rich in antioxidants may also help, though the research for this is less conclusive (Smits et al 2019) . .

Cut back on alcohol . Drinking excessively can reduce your sperm quality (NICE 2013) . The NHS recommends drinking no more than 14 units of alcohol a week, spread out over at least three days. Try to stay well within these guidelines while you’re trying to conceive. One unit of alcohol is about half a pint of standard-strength beer or a 25ml measure of spirits, while a small (125ml) glass of wine contains 1.5 units (NHS 2017a) . .

Your testicles make the best sperm when they’re slightly cooler than the rest of your body. So you may want to avoid having a laptop resting in your lap, spending lots of time in a hot environment, or sitting still for long periods of time. The research is still out on whether wearing loose-fitting underwear can help, but it may be worth a try (NICE 2013, NHS 2017) .

Feeling calm and relaxed makes it much easier to get in the mood for sex (NICE 2013, NHS 2017a) , and in some circumstances it may actually improve your sperm quality (NHS 2017a) . So if you’re trying to conceive, take it easy as much as possible (NICE 2013, NHS 2017a) .

After all, celebrities such as Robert De Niro and Mick Jagger have fathered healthy babies well into their twilight years. And according to Guinness World Records, the oldest man to father a child was an incredible 92 years old at the time of the birth! However, the truth about male fertility and age may surprise you.In short, yes. Although most men are able to have children well into their 50s and beyond, it becomes gradually more difficult after the age of 40. There are many reasons for this, including:These factors don’t necessarily mean that you won’t be able to father a child in later life. But they do mean that it’s likely to be more difficult.Yes, the older you are, the longer it’s likely to take for you and your partner to conceive. This is true no matter how old she isOn average, if both partners in a couple are under 25, they'll usually conceive within five months. But if the woman's under 25 and the man is over 40, it can take up to two yearsUnfortunately, certain genetic conditions do seem to be more common among babies with older fathers. You may be at a slightly increased risk of having a baby with the following conditions as you get older, particularly in your 40s and beyond:Sadly, your risk of conceiving a pregnancy which ends in miscarriage may also increase as you age, particularly once you're over 40, and if your partner is over 35Some research has suggested that babies with a father younger than 20 may be more at risk of low birth weight and low Apgar scores. However, other studies haven’t found the same resultsAlthough your age may influence these risks, it’s only one of a large number of factors. Other aspects of your life and your partner’s life, such as your family medical history and your lifestyle, will have a much bigger effect.Yes, it does. As you age, your sperm is more likely to contain damaged DNA, which can make it more difficult to have a healthy baby. Your partner’s eggs have a built-in mechanism that can repair damaged DNA introduced by sperm. But the older she is, the less effective this will be. That's why some of the risks of genetic disorders only matter when both the mum and dad are older.Happily, there’s plenty that you can do to keep your fertility and potency in tip-top condition. The following can all help to safeguard your chances of conceiving a healthy baby:These tips may help to keep your fertility in tip-top condition. However, bear in mind that even healthy, fertile couples still sometimes take a little while to conceive.If you and your partner have been trying for a baby without success for a year or more, go and see your GP. If your partner’s over 35, or either of you have any history of infertility, see your GP sooner than this. He’ll arrange for you both to have tests, to see whether there could be a medical reason for your difficultiesFinally, you can comfort yourself with the fact that, while male fertility may gradually decline through the years, some men will still be able to father a healthy child well into their 50s and beyond.Find out how your lifestyle can affect your fertility , and discover the best sex positions for getting pregnant
