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
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 an ectopic pregnancy
Physical problems with the uterus
Uterine fibroids, which are non-cancerous clumups of tissue and muscle on the walls of the uterus.
Many things can change a woman's ability to have a baby. These include:
Many women are waiting until their 30s and 40s to have children. In fact, about 20% is as a result to age related issue, age is a growing cause of fertility problems. About one-third of couples in which the woman is over 35 have fertility problems.
Aging decreases a woman's chances of having a baby in the following ways:
Most experts suggest at least one year. Women 35 or older should see their doctors after six months of trying. A woman's chances of having a baby decrease rapidly every year after the age of 30.
Some health problems also increase the risk of infertility. So, women should talk to their doctors if they have:
It is a good idea for any woman to talk to a doctor or mothers before trying to get pregnant. Doctors can help you get your body ready for a healthy baby. They can also answer questions on fertility and give tips on conceiving.
Doctors will do an infertility checkup. This involves a physical exam. The doctor will also ask for both partners' health and sexual histories. Sometimes this can find the problem. However, most of the time, the doctor will need to do more tests.
In men, doctors usually begin by testing the semen. They look at the number, shape, and movement of the sperm. Sometimes doctors also suggest testing the level of a man's hormones.
In women, the first step is to find out if she is ovulating each month. There are a few ways to do this. A woman can track her ovulation at home by:
Doctors can also check ovulation with blood tests. Or they can do an ultrasound of the ovaries. If ovulation is normal, there are other fertility tests available.
Hysterosalpingography (HIS-tur-oh-sal-ping-GOGH-ru-fee): This is an x-ray of the uterus and fallopian tubes. Doctors inject a special dye into the uterus through the vagina. This dye shows up in the x-ray. Doctors can then watch to see if the dye moves freely through the uterus and fallopian tubes. This can help them find physical blocks that may be causing infertility. Blocks in the system can keep the egg from moving from the fallopian tube to the uterus. A block could also keep the sperm from reaching the egg.
Laparoscopy (lap-uh-ROS-kuh-pee): A minor surgery to see inside the abdomen. The doctor does this with a small tool with a light called a laparoscope (LAP-uh-roh-skohp). She or he makes a small cut in the lower abdomen and inserts the laparoscope. With the laparoscope, the doctor can check the ovaries, fallopian tubes, and uterus for disease and physical problems. Doctors can usually find scarring and endometriosis by laparoscopy.
Finding the cause of infertility can be a long and emotional process. It may take time to complete all the needed tests. So don't worry if the problem is not found right away.
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, specific treatments for infertility based on:
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.
Some common medicines used to treat infertility in women include:
Clomiphene citrate (Clomid): This medicine causes ovulation by acting on the pituitary gland. It is often used in women who have polycystic ovary syndrome (PCOS) or other problems with ovulation. This medicine is taken by mouth.
Human menopausal gonadotropin or hMG (Repronex, Pergonal): This medicine is often used for women who don't ovulate due to problems with their pituitary gland. hMG acts directly on the ovaries to stimulate ovulation. It is an injected medicine.
Follicle-stimulating hormone or FSH (Gonal-F, Follistim): FSH works much like hMG. It causes the ovaries to begin the process of ovulation. These medicines are usually injected.
Gonadotropin-releasing hormone (Gn-RH) analog: These medicines are often used for women who don't ovulate regularly each month. Women who ovulate before the egg is ready can also use these medicines. Gn-RH analogs act on the pituitary gland to change when the body ovulates. These medicines are usually injected or given with a nasal spray.
Metformin (Glucophage): Doctors use this medicine for women who have insulin resistance and/or PCOS. This drug helps lower the high levels of male hormones in women with these conditions. This helps the body to ovulate. Sometimes clomiphene citrate or FSH is combined with metformin. This medicine is usually taken by mouth.
Bromocriptine (Parlodel): This medicine is used for women with ovulation problems due to high levels of prolactin. Prolactin is a hormone that causes milk production.
Many fertility drugs increase a woman's chance of having twins, triplets, or other multiples. Women who are pregnant with multiple fetuses have more problems during pregnancy. Multiple fetuses have a high risk of being born too early (prematurely). Premature babies are at a higher risk of health and developmental problems.
