The average age at which couples are having children has been rising steadily for the past several decades. Since menopause eventually prevents natural conception and pregnancy in women, female fertility is typically the focus of this increase in age. Furthermore, we've all seen and heard stories about men becoming fathers well into their 70s; if you didn’t know better, you’d think that a man’s fertility stays steady throughout his life - as long as he can continue to produce sperm, he can do his part in the conception process.
Despite studies showing a decline of fertility as a man gets older, the impact on fertility and pregnancy appears to be small and does not usually have a major effect on a couple's decision to get pregnant or proceed with fertility therapy.
Male fertility changes with age
In actuality, there are a number of significant changes that take place to a man’s physiology as he ages that can dramatically impact fertility and reproduction. Some of the major changes in male fertility include:
- Lower sperm count: While you’ll most likely continue to produce sperm throughout your life cycle, you’re going to produce less as you age. In fact, once you pass the age of 35, your sperm count (and semen volume) will both decline a little bit each year.
- Lower testosterone levels: Part of the reason for your declining sperm count has to do with lower levels of the male hormone testosterone. Testosterone plays an important role in sperm production, and its decline can impact you in other areas, such as lower energy levels as you age.
- More abnormal sperm: Unlike women – who have a set number of eggs that last throughout her reproductive years – men continue to regenerate sperm. As this happens through the years, however, the new sperm are more likely to have genetic mutations. For example, a 2003 study in The Journal of Urology found that in about 50% of cases where a baby was born with Down syndrome to older parents, the man’s sperm was the primary cause. Another study showed that children born to men between the ages of 45 and 49 were twice as likely to have schizophrenia when compared with men 25 and under. That risk tripled when the men hit the age of 50.
Slowing the decline in male fertility
There are a number of things you can do in terms of your lifestyle, however, to slow your declining fertility. For example:
- Reach and maintain an optimal weight
- Avoid the use of recreational drugs
- Quit smoking
- Reduce cholesterol (which can also help reduce erectile dysfunction)
- Ask your doctor to check your testosterone levels
If you and your partner are trying to conceive and having a hard time, don’t be afraid to get fertility testing. A fertility specialist can help to rule out certain male infertility causes. Not only that, you may be able to uncover an underlying problem that’s affecting your fertility, such as testicular cancer.
Infertility isn’t just a woman’s problem, especially as you age. If you want to become a dad over the age of 35, you need to understand what happens to your physiology as you age, make lifestyle changes to support your fertility and be willing to see a fertility specialist.
Trying to get pregnant can be a difficult task based on a variety of factors, but many do not consider that the age of the man may have something to do with it. There is always lots of fuss about the health of the woman, and very little about the health of the man involved in the equation.

As a man ages, several different things could be happening to his sperm that may create an issue in terms of impregnating a woman. The number of sperm produced may decrease, which will make it difficult to conceive. As if this was not enough, the mobility of the sperm that is available could be severely compromised. This means that even if there are enough sperm to fertilize an egg, they may not be able to move well or quickly enough to actually be able to do so. There are also issues with sperm that could cause their size and shape to change, and create issues with conception.
What to do
If you are having problems conceiving, consider the fact that the problem may not lie with your reproductive organs, but your partner. The two of you should go see a doctor together, to determine the best course of action. You will likely have to see a urologist to have a semen analysis conducted, to see how you are doing your part in the reproduction process. If the problem falls in your partner’s sperm count or mobility rather than your uterus, you will be given a list of possible options, and be consulted on the best course of action. It could be a simple blockage preventing sperm from making its way into the ejaculate fluid, or enlarged veins. There are surgical procedures to correct these issues. If either of these is not the case, there are fertility drugs to help your partner (no, they are not just for you!) increase the regularity of his sperm. If all of this fails, you and your partner can look at other treatments like artificial insemination, or in-vitro fertilization to help you conceive your child.
What it could mean for your child?
Reduced sperm mobility and other issues that arise with sperm as a man ages could result in an increase in genetic conditions in your children. This is because there are more DNA mutations in the sperm as a man gets older than before.
The most important thing to do is to stay strong and keep healthy. Pay attention to your diet, exercise, and even the amount of rest you get. The healthier you are, the more likely you will be able to conceive… and this is true for the both of you. No matter the point in your life which you are able to conceive a child, you should always take it as a blessing and do your best to care for the child, as you would at any time in your life.
