Infertility means not being able to get pregnant after one year of trying (or six months if a woman is 35 or older). Women who can get pregnant but are unable to stay pregnant may also be infertile.
Pregnancy is the result of a process that has many steps. To get pregnant:
- A woman’s body must release an egg from one of her ovaries (ovulation).
- The egg must go through a fallopian tube toward the uterus(womb).
- A man’s sperm must join with (fertilize) the egg along the way.
- The fertilized egg must attach to the inside of the uterus (implantation).
Infertility can happen if there are problems with any of these steps.
Is infertility a women problem?
No, infertility is not always a woman’s problem. Both women and men can have problems that cause infertility. About one-third of infertility cases are caused by women’s problems. Another one third of fertility problems are due to the man. The other cases are caused by a mixture of male and female problems or by unknown problems.
Most cases of female infertility are caused by problems with ovulation. Without ovulation, there are no eggs to be fertilized. Some signs that a woman is not ovulating normally include irregular or absent menstrual periods.
Ovulation problems are often caused by polycystic ovarian syndrome (PCOS). PCOS is a hormone imbalance problem which can interfere with normal ovulation. PCOS is the most common cause of female infertility. Primary ovarian insufficiency (POI) is another cause of ovulation problems. POI occurs when a woman’s ovaries stop working normally before she is 40. POI is not the same as early menopause.
Less common causes of fertility problems in women include:
- Blocked fallopian tubes due to pelvic inflammatory disease, endometriosis, or surgery for ectopic pregnancy
- Physical problems with the uterus
- Uterine fibroids, which are non-cancerous clumps of tissue and muscle on the walls of the uterus.
Many things can change a woman’s ability to have a baby. These include:
- Age
- Smoking
- Excess alcohol use
- Stress
- Poor diet
- Athletic training
- Being overweight or underweight
- Sexually transmitted infections (STIs)
- Health problems that cause hormonal changes, such as polycystic ovarian syndrome and primary ovarian insufficiency.
Infertility in men is most often caused by:
- A problem called varicocele. This happens when the veins on a man’s testicle(s) are too large. This heats the testicles. The heat can affect the number or shape of the sperm.
- Other factors that cause a man to make too few sperm or none at all.
- Movement of the sperm. This may be caused by the shape of the sperm. Sometimes injuries or other damage to the reproductive system block the sperm.
Sometimes a man is born with the problems that affect his sperm. Other times problems start later in life due to illness or injury. For example, cystic fibrosis often causes infertility in men.
A man’s sperm can be changed by his overall health and lifestyle. Some things that may reduce the health or number of sperm include:
- Heavy alcohol use
- Drugs
- Smoking cigarettes
- Age
- Environmental toxins, including pesticides and lead
- Health problems such as mumps, serious conditions like kidney disease, or hormone problems
- Medicines
- Radiation treatment and chemotherapy for cancer
Infertility can be treated with medicine, surgery, artificial insemination, or assisted reproductive technology. Many times these treatments are combined. In most cases infertility is treated with drugs or surgery.
Doctors recommend specific treatments for infertility based on:
- Test results
- How long the couple has been trying to get pregnant
- The age of both the man and woman
- The overall health of the partners
- Preference of the partners
Doctors often treat infertility in men in the following ways:
- Sexual problems: Doctors can help men deal with impotence or premature ejaculation. Behavioral therapy and/or medicines can be used in these cases.
- Too few sperm: Sometimes surgery can correct the cause of the problem. In other cases, doctors surgically remove sperm directly from the male reproductive tract. Antibiotics can also be used to clear up infections affecting sperm count.
- Sperm movement: Sometimes semen has no sperm because of a block in the man’s system. In some cases, surgery can correct the problem.
In women, some physical problems can also be corrected with surgery.
A number of fertility medicines are used to treat women with ovulation problems. It is important to talk with your doctor about the pros and cons of these medicines. You should understand the possible dangers, benefits, and side effects.
Intrauterine insemination (IUI) is an infertility treatment that is often called artificial insemination. In this procedure, the woman is injected with specially prepared sperm. Sometimes the woman is also treated with medicines that stimulate ovulation before IUI.
IUI is often used to treat:
- Mild male factor infertility
- Women who have problems with their cervical mucus
- Couples with unexplained infertility

Assisted reproductive technology (ART) is a group of different methods used to help infertile couples. ART works by removing eggs from a woman’s body. The eggs are then mixed with sperm to make embryos. The embryos are then put back in the woman’s body.
Common methods of ART include:
- In vitro fertilization (IVF) means fertilization outside of the body. IVF is the most effective ART. It is often used when a woman’s fallopian tubes are blocked or when a man produces too few sperm. Doctors treat the woman with a drug that causes the ovaries to produce multiple eggs. Once mature, the eggs are removed from the woman. They are put in a dish in the lab along with the man’s sperm for fertilization. After 3 to 5 days, healthy embryos are implanted in the woman’s uterus.
- Zygote intrafallopian transfer (ZIFT) or Tubal Embryo Transfer is similar to IVF. Fertilization occurs in the laboratory. Then the very young embryo is transferred to the fallopian tube instead of the uterus.
- Gamete intrafallopian transfer (GIFT) involves transferring eggs and sperm into the woman’s fallopian tube. So fertilization occurs in the woman’s body. Few practices offer GIFT as an option.
- Intracytoplasmic sperm injection (ICSI) is often used for couples in which there are serious problems with the sperm. Sometimes it is also used for older couples or for those with failed IVF attempts. In ICSI, a single sperm is injected into a mature egg. Then the embryo is transferred to the uterus or fallopian tube
Assisted reproductive technology procedures sometimes involve the use of donor eggs (eggs from another woman), donor sperm, or previously frozen embryos.
Donor eggs are sometimes used for women who cannot produce eggs. Also, donor eggs or donor sperm are sometimes used when the woman or man has a genetic disease that can be passed on to the baby.
An infertile woman or couple may also use donor embryos. These are embryos that were either created by couples in infertility treatment or were created from donor sperm and donor eggs. The donated embryo is transferred to the uterus. The child will not be genetically related to either parent.
Surrogacy
Women with no eggs or unhealthy eggs might also want to consider surrogacy. A surrogate is a woman who agrees to become pregnant using the man’s sperm and her own egg. The child will be genetically related to the surrogate and the male partner.
Gestational Carrier
Women with ovaries but no uterus may be able to use a gestational carrier. This may also be an option for women who shouldn’t become pregnant because of a serious health problem. In this case, a woman uses her own egg. It is fertilized by her partner’s sperm and the embryo is placed inside the carrier’s uterus.
Just because something isn’t happening for you right now doesn’t mean that will never happen. Even miracles take little time.
