Egg quantity and quality
People with ovaries are born with a finite egg supply. Both the number and quality of eggs decline with time, especially from the mid-30s onward.
This can affect natural conception, miscarriage risk, and IVF success rates.
Male age also matters
Sperm production continues across life, but sperm quality and DNA integrity may change with age and health factors.
A fertility evaluation should include both partners rather than focusing only on the female partner’s age.
Planning does not mean pressure
Understanding age-related fertility helps patients plan testing, treatment timing, egg freezing, or embryo freezing with clearer expectations.
