Women want children earlier (because menopause) and are more affected by them (because giving birth) than equally family-minded men. As a result, women are more motivated to prioritise having children/family.
In addition, men derive more advantage from more money/power than women, so they're more motivated to climb the corporate ladder (or take risks and fund companies) than women.
I'm generalising, obviously, so "on average" everywhere.
women need to have children earlier.
I don't see 70 year old men eagerly having kids all that often. Most people want to live to see their grandchildren.
