Understanding the role that paternal age has on infertility is essential to taking a measured, intelligent approach to your reproductive journey. Where women are born with an established and finite number of eggs in their ovaries, men are able to generate sperm for the entire course of their lives.
Men produce sperm into their 60s and 70s, but not all sperm is the same. Age and male infertility are linked and age can affect sperm’s morphology (shape) and motility (movement), which are important for successful conception to occur.
Assuming a woman is younger than 25; if her partner is also younger than 25, it takes an average of five months to get pregnant. If her partner is older than 40 years, it takes around two years, and even longer if he is older than 45.
It takes longer for partners of men older than 40 years to conceive. Also, the risk of miscarriage is higher for women whose male partner is older than 45 , compared to men younger than 25 years of age.
For couples having IVF, the chance of having a baby is higher if the man is younger than 41 years of age.
