Infertility means you cannot make a baby (conceive).
Infertility is grouped into two categories:
- Primary infertility refers to couples who have not become pregnant after at least 1 year of unprotected sex (intercourse).
- Secondary infertility refers to couples who have been pregnant at least once, but are not able to get pregnant now.
Inability to conceive; Unable to get pregnant
Causes, incidence, and risk factors
A wide range of physical and emotional factors can cause infertility. Infertility may be due to problems in the woman, man, or both.
Female infertility may occur when:
- A fertilized egg or embryo does not survive once it sticks to the lining of the womb (uterus)
- The fertilized egg does not attach to the lining of the uterus
- The eggs cannot move from the ovaries to the womb
- The ovaries have problems producing eggs
Female infertility may be caused by:
Autoimmune disorders, such as antiphospholipid syndrome (APS)
- Cancer or tumor
- Clotting disorders
- Growths (such as fibroids or polyps) in the uterus and cervix
- Birth defects that affect the reproductive tract
- Excessive exercising
- Eating disorders or poor nutrition
- Use of certain medications, including chemotherapy drugs
- Drinking too much alcohol
- Older age
Ovarian cystsand polycystic ovary syndrome(PCOS)
- Pelvic infection or
pelvic inflammatory disease(PID)
- Scarring from sexually transmitted infection, previous abdominal surgery, or endometriosis
- Surgery to prevent pregnancy (tubal ligation) or failure of tubal ligation reversal (reanastomisis)
- Thyroid disease
- Too little or too much of certain hormones
Male infertility may be due to:
A decrease in sperm count
- Sperm being blocked from being released
Sperm that do not work properly
Male infertility can be caused by:
Being in high heat for prolonged periods
Cancer treatments, including chemotherapy and radiation
Heavy use of alcohol, marijuana, or cocaine
Scarring from sexually transmitted infections, injury, or surgery
Too little or too much hormones
Use of certain drugs, such as cimetidine, spironolactone, and nitrofurantoin
Vasectomy, or failure of vasectomy reversal
In healthy couples under age 30 who have sex regularly, the chance of getting pregnant is about 25 – 30% per month.
A woman’s peak fertility occurs in her early 20s. After age 35 (and especially 40), the chance that a woman can get pregnant drops considerably. The age when fertility starts to decline is different from woman to woman.
Signs and tests
When you should get treated for infertility depends on your age. Doctors often suggest that women under 30 should try to get pregnant on their own for 1 year before getting tested.
Infertility testing involves a complete medical history and physical examination of both partners.
Blood and imaging tests will be done. In women, this may include:
- Blood tests to check hormone levels, including progesterone and follicle stimulating hormone
- Taking body temperature first thing in the morning to check if the ovaries are releasing eggs
- FSH and clomid challenge test
- Pelvic ultrasound
Luteinizing hormone urine test(ovulation prediction)
Thyroid function tests
Tests in men may include:
- Examination of the testes and penis
- Ultrasound of the male genitals (sometimes done)
- Blood tests to check hormone levels
Testicular biopsy(rarely done)
Treatment depends on the cause of infertility. It may involve:
Education and counseling
Fertility treatments such as intrauterine insemination (IUI) and
in vitro fertilization(IVF)
Medicines to treat infections and clotting disorders
Medicines that help the woman grow and release eggs from the ovaries
You can increase your chances of becoming pregnant each month by having sex at least every 3 days before and during ovulation. It is especially important to do so before ovulation occurs. Sperm can live inside a woman’s body for at least 3 days. However, a woman’s egg can only be fertilized by the sperm for a few hours after it is released.
Ovulation occurs about 2 weeks before the next menstrual cycle (period) starts. If a woman gets her period every 28 days, the couple should have sex at least every 3 days between the 10th and 18th day after the period starts.
If you are under- or overweight, getting to a healthier weight may increase your chance of getting pregnant.
Sharing with others who have similar fertility challenges can help you not feel alone. Ask your health care provider to recommend local groups. Or check the internet for resources.
As many as 1 in 5 couples diagnosed with infertility eventually become pregnant without treatment.
More than half of couples with infertility become pregnant after treatment, not including advanced techniques such as in vitro fertiliziation (IVF).
Calling your health care provider
Call for an appointment with your health care provider if you are unable to get pregnant.
Preventing sexually transmitted infections (STIs), such as gonorrhea and chlamydia, may reduce your risk of infertility.
Maintaining a healthy diet, weight, and lifestyle may increase your chance of getting pregnant and having a healthy pregnancy.
