Male and female fertility function very differently.
Men remain fertile throughout their lives, while women have a limited reproductive window. This is because men continuously produce s***m, generating about 1,500 s***m per second, while women are born with a fixed number of eggs — approximately 1 million at birth.
That egg supply gradually declines without regeneration.
Each month, a woman releases a single egg that remains viable for only 12 to 24 hours, whereas s***m can survive in the female reproductive tract for up to three days.
While male fertility is relatively consistent from the time of puberty until *very* late in life, female fertility begins at puberty and ends with menopause, creating a clear biological distinction between the two.
That said, age plays a significant role in fertility decline for both genders, but its impact is more pronounced in women.
A woman’s chances of conceiving naturally drop from 25% when under age 30 to just 5% at age 40 and over. Men experience fertility decline starting around age 40 to 45, as testosterone levels and s***m quality decrease.
Infertility can affect both sexes, with 40% of cases linked to female factors, 30% to male factors, and 20% involving both partners.
Lifestyle choices, such as weight and smoking, also contribute to fertility challenges, alongside genetic factors that influence egg supply and s***m production.
