A new sperm study has shown that male fertility declines in their mid-40s.
Scientists from Genea, a world-leading IVF clinic in Australia, analyzed more than 40,000 sperm tests.
They understood that the quality of sperm decreased significantly with advancing age.
Cheryl Phua, Genea Fertility Specialist, said the situation is getting worse for men over 55.
This is because there are fewer motile sperm and the DNA information that the sperm contains is damaged.
Fertility problems can make it difficult for couples to get pregnant, and miscarriages are more likely, added Dr. Phua added.

The specialist said Genea mostly sees women asking for help, but studies have found that up to 40 percent of infertility is linked to male reproductive problems – which are often not treated properly.
The expert said 9News : “We found that sperm quality was significantly reduced; actual damage to DNA or the packages of genetic information contained in the sperm head.”
Dad of two, David Hodge, said he was surprised to hear that such a high percentage of infertility cases are due to men since the subject is not discussed.
He and his wife Sarah tried to get pregnant for three years before undergoing a sperm test that revealed problems.
David said, “I could have a procedure done to extract the semen and start a family from there.”
IVF enabled David and Sarah to have two daughters, Emmi and Layla.
An earlier study published at a meeting of the European Society of Human Reproduction and Embryology in Vienna (Austria) found that male fertility is drastically reduced after the age of 50.
Women enter menopause at 51 on average, and scientists have calculated that men at this age see a similar drop in pregnancy rates.
The researchers tracked more than 4,200 men trying to have babies through IVF and identified the point where they appeared to be reaching “manopause”.
Those 51 and older were 34 percent less likely to get pregnant than those under 35.
Dr. Guy Morris of University College London said, “The quality and quantity of sperm decreases with age and this has decreased after age 50.
“Stories of celebrity men fathering children as young as 60 can give a skewed perspective on the potential risks of delaying fatherhood.”
The pregnancy rate in partners of men under 35 years of age was 50 percent, in men aged 51 it fell to just 30 percent.
