FERTILITY BASICS

Fertility declines naturally as women age.

A healthy 30-year-old woman has about
a 25%—30% chance of getting pregnant naturally each month.

A healthy 40-year-old woman has a 10% or lower chance of getting pregnant naturally
each month.

Certain health conditions can affect fertility:

Infrequent or irregular periods
History of recurrent miscarriage (2 or more)
Ovulation disorders or hormone
imbalances like polycystic ovary
syndrome (PCOS)
Endometriosis
Uterine growths (like fibroids or polyps)
Blocked fallopian tubes or
uterine disorders
Diminished ovarian reserve and/or
poor egg quality

While not always a cause of fertility 
issues, lifestyle can sometimes play a role.

Weight (being significantly
under- or overweight)
Male partner’s drug use
Smoking
Excessive physical or
emotional stress
