Male fertility ‘decreases after 40’

MEN should plan on being a parent before their 40th birthday, new research reveals.

Unlike women, most men are not even aware that their biological clock is ticking away. Now French fertility experts are warning that while the age of 35 should be considered the “amber light” in a woman’s reproductive life, men reach a similar milestone at 40.

Their examination of 1,938 couples from 59 clinics found that a woman under 30 years is 25% less likely to conceive if her partner is 40 or older.
