A woman is said to be infertile when she is unable to become pregnant within 1 year of having unprotected sexual intercourse regularly, after ruling out male causes.
There are a great variety of causes of greater or lesser severity. That is why in many cases it may happen that the woman is not aware of her problem until the necessary sterility tests are performed, since in many cases she does not show any symptoms.
There are 2 types of sterility:
- Primary
- is when we have never been able to get pregnant.
- Secondary
- is when we do not achieve gestation despite having one or more previous children with the same partner.

To know the state of our ovarian reserve, it is best to perform an ultrasound to assess the antral follicle count, and a hormone analysis to determine the levels of FSH and antimullerian hormone.
And finally, it is necessary to know that the period of greatest fertility in women is from 16 to 30-35 years of age approximately, with fertility being clearly affected from the age of 40 onwards.
