Infertility

Also called Fertility problems or Subfertility

Infertility is when a couple cannot get pregnant despite having regular unprotected sex. Most couples conceive within a year of trying. Causes can affect either partner, or both, and include problems with ovulation, damaged fallopian tubes, endometriosis, and problems with sperm. Sometimes no cause is found.

What it is

Age is an important factor, as fertility declines with age, especially for women over 35.

Treatment depends on the cause and may include medicines to help ovulation, surgery, or assisted conception such as IUI or IVF.

Common signs

  • Not getting pregnant after a year of regular unprotected sex
  • Irregular or absent periods
  • Pain during periods or sex, sometimes

How it is usually diagnosed

  • Blood tests for hormones
  • Semen analysis
  • Pelvic ultrasound
  • Tests to check the fallopian tubes

Records worth keeping

Keeping these together makes each appointment easier, especially when you see a new doctor:

  • Hormone test results
  • Semen analysis reports
  • Ultrasound and tube test reports
  • Fertility clinic letters and treatment cycle notes

Questions to ask your doctor

  • What tests should we both have?
  • What treatment options do we have?
  • How do our ages affect our chances?

When to get help right away

Call 112 or go to the nearest emergency department if you have:

  • Severe tummy pain, swelling or breathlessness during fertility treatment, or one-sided pain with a positive pregnancy test: get urgent medical help
