What is Infertility?

Infertility is generally described as one year of trying to get pregnant (with frequent unprotected sex) without any success. Female infertility affects millions of women in the United States, as well as male infertility (or a combination of the two).

How Does the Doctor Determine Infertility?

When women are examined for infertility, it typically begins with going over medical history and a physical exam, as well as a pelvic exam. The doctor will then check to see if you are having regular ovulation cycles and will examine the ovaries to see if they are releasing their eggs. Additionally, blood tests will be taken to measure hormone levels. The ovaries and uterus may also be examined to check the uterus and fallopian tubes through an ultrasound. 

With the majority of couples, the following problems that lead to infertility include one or more of the following:

  • Ovulation problem
  • Blockage of the fallopian tubes
  • Sperm problem 

What Causes Female Infertility?

As mentioned above, ovulation problems and blockage of fallopian tubes are common causes for infertility in women. However, there are many other causes of female infertility, such as:

  • Ovulation disorders, such as polycystic ovary syndrome (PCOS)
  • Uterine or cervical abnormalities
  • Endometriosis
  • Early menopause
  • Fallopian tube damage

When to See a Doctor

When to see a doctor for infertility ultimately depends on your age:

  • If you’re up to age 35, most doctors recommend trying to get pregnant for at least a year before seeking testing or treatment.
  • If you’re between the ages of 35 and 40, you should discuss testing or treatment with your doctor after six months of trying.
  • If you’re older than 40, then you should discuss testing and treatment with your doctor as soon as possible.

Additionally, your doctor may want to start testing or treatment right away if:

  • Your partner has known infertility problems
  • You have a history of painful or irregular periods
  • Pelvic inflammatory disease
  • Recurring miscarriages
  • Prior cancer treatment
  • Endometriosis
