The website of the world record authority Guinness World Records lists the oldest father ever as Australian Les Colley (1898-1998), who allegedly fathered his ninth child at age 92 with a Fijian woman he met through a dating agency.
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.
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: Sperm quality tends to decrease with age.
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.
The oldest ever man to father a child was reportedly Les Colley (1898 - 1998, Australia), who had his ninth child a son named Oswald to his third wife at the age of 92 years 10 months. Colley met Oswald's Fijian mother in 1991 through a dating agency at the age of 90.
The oldest recorded mother to date to conceive was 73 years, while the youngest mother was 5 years old. According to statistics from the Human Fertilisation and Embryology Authority, in the UK more than 20 babies are born to women over age 50 per year through in-vitro fertilization with the use of donor oocytes (eggs).
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.
As the father grows older, the number of mutations in the father's genome increases, leading to an increase in the incidence of congenital malformations in offspring [11, 65]. Older paternal age may be harmful to the offspring's health in terms of genetic mutations, telomere length, and epigenetics [66].
A recent study suggests that a 20-year-old father doubles the chance of Down syndrome as compared to one who's 40.
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.
"Studies have also proved that children of older men are also at higher risk of developing a chronic disease in the future," states Ghayda. Conditions found to be related to older paternal age include: Acute lymphoblastic leukemia. Schizophrenia.
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.
Having babies after the age of 35 increases the risk of miscarriage, birth defects and other birth-related complications for women. The same doesn't exactly apply for men. Although sperm quality declines with age, men can and do father children well into old age – just ask Mick Jagger, Warren Beatty or Rupert Murdoch.
Pregnancy in Your 40s
If you get pregnant after 35 years old, experts call this an “advanced maternal age” pregnancy. But it's still possible to get pregnant and deliver a healthy baby in your 40s. Childbirth at older ages has become more common too. Since the 1990s, birth rates in people aged 40-44 have gone up.
Another study that evaluated the relationship between age and semen parameters also concluded that male fertility decline begins at 35, and suggested that male fertility peaks between 30 and 35. Bottom line: Men generally see a decrease in fertility beginning at 35, and the decline progresses from there.
One of the measures of semen that increases with age is sperm fragmentation. This is associated with chromosomal abnormalities in fetuses. Studies show that fathers over the age of 40 increase the risk of preterm birth (less than 37 weeks) and very preterm birth (less than 32 weeks).
A recent study of more than 40.5 million births in the United States revealed potentially harmful effects of advanced paternal age on a baby's risk of prematurity, low birth weight, low Apgar score and risk of seizures, as well as the mother's chances of developing gestational diabetes.
While a 92-year-old woman delivering a 60-year-old baby may sound like a bizarre plot twist from the movie “Benjamin Button,” it's true. Huang Yijun, 92, of southern China, recently delivered a child which she'd been carrying for well over half a century. The baby wasn't alive, however.
Geriatric pregnancy is a rarely used term for having a baby when you're 35 or older. Rest assured, most healthy women who get pregnant after age 35 and even into their 40s have healthy babies.
Pregnancy after age 45 years is infrequent and the mother and baby should be considered as a high risk. There is a greater incidence of spontaneous abortion, gestational trophoblastic disease and chromosomal abnormalities in the fetus.
What is the longest recorded human pregnancy? The longest recorded human pregnancy was 375 days, or just over 12 months.
By age 43, your egg supply is near its end. Your risk of pregnancy complications, such as high blood pressure and gestational diabetes, increases after 35 as well, and continues to rise into your 40s. Miscarriage rates begin to skyrocket in your 40s as well.
Pregnancy Risks in Advanced Maternal Age
Your chance of miscarriage is increased, along with an increased risk of developing gestational diabetes, high blood pressure, and having a child that is preterm. You are also at risk for conceiving a child who has a chromosomal abnormality, such as Down's syndrome.
One study estimated a woman can have around 15 pregnancies in a lifetime. And depending on how many babies she births for each pregnancy, she'd probably have around 15-30 children.
