Male fertility generally starts to reduce around age 40 to 45 years when sperm quality decreases.
Although a man's fertility can theoretically last until death, sperm production has been found to decline from around the age of 50. Although it is still possible to conceive a child, and many men do have children in their 50s or later, it may take longer for you and your partner to become pregnant.
And importantly, unlike a woman who reaches menopause when she runs out of eggs, men experience male fertility decline, but don't become infertile as a result of age. It is possible (though less likely) for men of any age to father a biological child.
Guys can father a child at any age, right? Well, not exactly. While it's true men continue to produce sperm into old age, it doesn't mean they'll be fertile at 50. And just as a woman's chances of getting pregnant start to decline in her mid-30s, so does a man's fertility.
There's no maximum age that stops a man from being able to have a baby. You can become a father long into your older years, but there are risks.
Am I too old? While certain risks may rise with age, men continue to produce sperm throughout their lives and can father healthy children into old age.
A trained expert checks your sperm count, their shape, movement, and other characteristics. In general, if you have a higher number of normal-shaped sperm, it means you have higher fertility. But there are plenty of exceptions to this. A lot of guys with low sperm counts or abnormal semen are still fertile.
Finally, 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.
As men age, they're more likely to have problems getting and maintaining an erection. There's no specific age at which erectile dysfunction (ED) starts. But ED is much more likely after the age of 50.
Sperm motility
Whereas sperm quality is at the best levels between ages 30-35, motility is best before age 25. And as with semen quality, motility declines dramatically after age 55.
There's no expiration date on when guys can father a child. Case in point: Rocker Mick Jagger just had his eighth child at the age of 73. Since men don't hit menopause—the time in a woman's life where her fertility ends—they can typically continue to father children into their later years.
The scientists also note that at the age of 35, the proportion of sperm carrying an X chromosome also seems to increase, meaning older dads are more likely to have daughters. In human reproduction, the Y chromosome is responsible for making a male child.
While fewer than 1 percent of first-time fathers are over 50, there are benefits to being a later-in-life father. Dr Paul Turek, a men's health and fertility urologist, says that men who have children at an older age tend to live longer. As an added bonus, their children tend to live longer as well.
Pregnancy rates decrease with paternal age. Men will generally see a 52% decrease in fertility rate between their early 30s and their mid-to-late 30s. Time to conception. Compared to men 25 years or younger, men 45 years or older are 12.5 times more likely to take over two years to conceive.
Men start losing their fertility at age 40.
In a study of more than 1,900 couples, irrespective of the woman's age, IVF attempts involving men 40 or older failed 70 percent more often than IVF attempts involving men younger than 30. Previous theory: Older men produce fewer kids because they get less sex.
Not all male infertility is permanent or untreatable; it is not uncommon for men to treat infertility through one or a combination of actions, even though the clinical effectiveness of many of these treatments has not been proven..
Diagnosis. An initial male fertility examination includes a medical history, physical examination, general hormone tests and one or more semen analyses, which measure semen volume as well as sperm number, ability to move spontaneously and quality of motion.
Signs that indicate that your sperm may be unhealthy
They are: Semen Color: Yellow color semen could indicate that you have jaundice or high consumption of alcohol or food that contains high concentration of sulfur. If your semen is greenish-yellow, it is an indication that there is a bacterial infection.
From a biological standpoint, experts recommend a man is best suited to fatherhood from his late 20s to early 30s. It is still possible for men to father a child in their 50s and older.
Even with all the understandable talk of “windows of opportunity” and “biological clocks,” there are ways for women over 35 to make motherhood a reality. Infertility treatments can be difficult and expensive, but fertility specialists can talk with you about options. Age is less of a limitation than it used to be.
Turns out, men have their own ages to be mindful of. “It's on a hockey stick shaped curve [of risks], just as it is with women, but with men the stick is a lot longer. The risks can start at 40 or maybe even 50 or 60 and then [risks] rapidly rise after 60,” says Dr. Paul Turek, a men's health and fertility urologist.
This means that a man with many brothers is more likely to have sons, while a man with many sisters is more likely to have daughters.
