Infertility diagnosis and treatment may require a number of medical tests. Some tests are quite simple, while others are more involved. Adequate testing is a critical part of your infertility workup and treatment. Your doctor will base his/her treatment plan on the outcome of you and your partner’s tests. Your doctor will start with simple, less invasive tests and then move on to those that are more involved.
If you are a man, you can expect your doctor to do a full history and physical examination and request a semen analysis. For a man to be fertile, he must produce a sufficient number of normally functioning sperm that are able to travel though his reproductive tract and be ejaculated into his partner’s vagina. The process requires the appropriate production of male hormones as well as the ability to engage successfully in sexual intercourse.
After your initial workup, your doctor will determine what additional tests, if any, are necessary. The sequence of testing may depend on your medical history and is often coordinated with the evaluation of your female partner. Other tests may include evaluation of male hormones and evaluations of other male issues, including genetics, ejaculatory duct obstruction, testicular function, and sexual function.
If you are a woman, you can expect your doctor to do a full history and examination, and evaluate your ovulatory status, cervix, fallopian tubes, and uterus.
Evaluation of ovulation:
The first step in diagnosing female-factor infertility is determining whether or not a woman is ovulating. The presence or absence of ovulation can be determined by daily changes in your basal body temperature, or with blood or urine tests.
Evaluation of the cervix:
The cervix is the lower part of the uterus that leads to the vagina. After sexual intercourse, ejaculated sperm must pass into the uterus from the vagina. Problems in the cervix may block the passage of sperm into the upper part of a woman’s reproductive tract, thus preventing the sperm from reaching the fallopian tubes and awaiting egg.
Your doctor may need to assess the thickness of your cervical mucus as well as the presence of sperm antibodies in the mucus. In the past this test, also known as the “postcoital test” was routinely performed, but studies have revealed that this test is not very reliable, therefore we perform it only very rarely and mostly for people who refuse a semen analysis for religious reasons.
Evaluation of the fallopian tubes:
To fertilize an egg, sperm must travel through the uterus and into the fallopian tubes. The fallopian tubes are a complex set of organs, one on each side of the pelvis, leading from the right or left ovary to the upper corner of the uterus. The diameter is nearly one-half inch at the open end near the ovary, and narrows to the size of a pencil tip near the uterus.
The fallopian tube is capable of picking up a newly released egg, providing nutrients and movement for the egg, transporting sperm up to the egg, sustaining an environment for fertilization and, finally, transporting the fertilized egg into the uterus. The fallopian tubes play a crucial role during reproduction and, at the very least, must be open throughout their entire length. Scarring, infection and inflammation can all interfere with fallopian tube function by causing blockages and other problems.
Hysterosalpingography (HSG) is a radiologic procedure to investigate the shape of the uterine cavity and the shape and patency of the fallopian tubes. It entails the injection of a radio-opaque material into the cervical canal and usually fluoroscopy with image intensification. A normal result shows the filling of the uterine cavity and the bilateral filling of the fallopian tube with the injection material. To demonstrate tubal patency (openness), spillage of the contrast material into the peritoneal cavity needs to be observed.
Evaluation of the uterus:
The uterus must be able to transport sperm to the fallopian tubes and, after fertilization, accept the fertilized egg, and allow the egg to implant in its wall. A congenital abnormality of the uterus, scar tissue following uterine surgery such as a D & C, fibroids, polyps, or adenomyosis can all interfere with normal uterine function. The Hysterosalpingogram (HSG) also helps in assessing the uterus.
Your doctor may recommend one or more of the following tests to evaluate the structure of your fallopian tubes and uterus:
Ultrasound
Ultrasound, or sonography, involves sending sound waves into the body. These sound waves are reflected off the internal organs, and special instruments then use those recorded reflections to create an image of the organs. No ionizing radiation (X-ray) is involved in ultrasound imaging.
With transvaginal ultrasound, the ultrasound transducer (a hand-held probe) is inserted directly into the vagina. Transvaginal ultrasound is most commonly used to examine the uterus and ovaries and to monitor the health and development of the embryo during pregnancy.
Ultrasound images can help to identify palpable masses such as ovarian cysts and fibroids, as well as ovarian or uterine cancers. IVF cycling patients are checked regularly with a transvaginal ultrasound to monitor the size and number of developing follicles.
Transvaginal ultrasound is performed very much like a gynecologic exam. The tip of the transducer is smaller than a gynecologic speculum. A protective cover lubricated with gel is placed over the transducer, which is then inserted into the vagina. Only two to three inches of the transducer end are inserted into the vagina. The images are obtained from different orientations to get the best views of the uterus and ovaries.
Hysterosonogram
Hysterosonogram, also called a saline-sonohysterogram, is a test to study the inner surface of the uterus. An ultrasound is performed using a vaginal probe, and at the same time saline solution is injected into the uterus through a thin catheter. This helps delineate the inner contents of the uterus. Lumps called submucosal fibroids or polyps cannot be seen well without the injection of saline solution. This test is used to find out the cause of heavy periods and to investigate infertility and repeated miscarriages.
It is best to have the procedure during the second week (days seven to 12) of your menstrual cycle. However, this procedure can be performed at any time during the menstrual cycle while on birth control pills. This timing reduces the chance that you may be pregnant during the procedure, and makes it easier to view the folds of the uterine cavity. Hysterosonograms are not usually uncomfortable, but if you are sensitive to pain or cramping you can ask your doctor about taking pain medication such as Tylenol or Ibuprofen. The test involves the following steps:
An ultrasound probe is placed in the vagina to inspect the uterus and ovaries.
A speculum is placed in the vagina and the doctor examines the cervix. The cervix is cleaned with antibacterial soap.
A thin, soft tube of about one to two millimeters in diameter is placed in the cervix.
The vaginal probe is reinserted into the vagina.
Water is injected into the uterus through the soft tube. The fluid causes the uterus to stretch.
This may cause uterine cramping.
The doctor spends about 3-5 minutes examining the uterine cavity and wall.
A small sample of tissue is sometimes obtained from the lining of the uterus at the end of the procedure, to rule out the presence of abnormal cells.
Your doctor will discuss the results of the hysterosonogram with you after the procedure. Based on the results, further tests may be needed. If a problem is detected, a treatment plan will be discussed with you.
A very few women have minor side effects after a hysterosonogram. These are not serious and usually go away after a day or two. Side effects may include cramps, slight vaginal bleeding, and sticky vaginal discharge as some of the gel and fluid drains out. A pad can be used for the vaginal discharge. Do not use a tampon.
Hysterosalpingogram (HSG)
Hysterosalpingogram is a procedure in which radiographic contrast (dye) is injected into the uterine cavity through the vagina and cervix and X-ray pictures are taken as the dye is expelled from your reproductive system. The uterine cavity fills with dye, and if the fallopian tubes are open, the dye will then fill the tubes and spill out into the abdominal cavity.
In this way we can determine whether the fallopian tubes are open or blocked, and whether the blockage is located at the junction of the tube and the uterus (proximal) or whether it is at the end of the fallopian tube (distal).
If a blockage is detected, we will discuss with you effective treatments for tubal factor infertility. Your HSG can also give us a better picture of the uterine cavity and detect the presence of polyps, fibroids, or scar tissue. The fallopian tubes can also be examined for defects within the tube or suggestion of a partial blockage.
The hysterosalpingogram takes only about five minutes to perform. During the procedure you are likely to experience some mild cramping, so you may wish to ask your doctor about taking pain medication such as Tylenol or Ibuprofen a half hour prior to the HSG.
The test involves the following steps:
The doctor places a speculum in the vagina and examines the cervix. Your cervix is cleaned with an antibacterial soap.
A clamp may be attached onto your cervix to hold it steady. A small, bendable plastic tube is gently pushed through the opening of your cervix into your uterus, and a tiny balloon on the end of the tube is filled with air to hold it temporarily in place.
The speculum is removed but the thin tube will be left in place, with one end (about six inches of tubing) remaining outside of your vagina.
A small amount of contrast dye is injected through the tube into your uterus, and several X-ray pictures are taken.
Your doctor may ask you to move your pelvis slightly or roll from side to side to provide the clearest view of your uterus.
You may experience some uterine cramping as the contrast dye goes into the tube.
The procedure is now complete. The balloon will be emptied of air from the outside and the tube will be gently pulled out.
After the procedure, your doctor will review the X-ray pictures and discuss the results of the hysterosalpingogram with you. You may experience slight vaginal bleeding and cramping after the procedure, and some sticky vaginal discharge as some of the gel and fluid drains out. A pad can be used for the vaginal discharge. Do not use a tampon.
Pregnancy rates in several studies have been reported to be slightly increased for several months following a hysterosalpingogram. This may be due to the flushing of the tubes with the contrast. However, this increase in pregnancy rates is only observed with oil based contrast material which, is not regularly used due to safety concerns.
Hysteroscopy
Hysteroscopy is a diagnostic and operative procedure performed with an instrument called a hysteroscope, which is a thin telescope that is inserted through the cervix into the uterus allowing better visualization of the uterine cavity. Hysteroscopy allows the doctor to clearly make out fibroids, polyps, and other problems that may be causing excessive menstrual bleeding and/or infertility.
Hysteroscopy is performed soon after menstruation because the uterine cavity is more easily evaluated early in the menstrual cycle and there is no risk of interrupting a pregnancy at this time.
During the procedure, an anesthesiologist administers light anesthesia (conscious sedation) to the patient, through an intravenous drip (IV). Hysteroscopes are so thin that they can often fit through the cervix with minimal or no dilation. The doctor will inject saline solution to expand the uterine cavity, clear blood and mucus away and view the internal structure of the uterus directly through the hysteroscope.
If abnormalities such as fibroids, polyps, scar tissue, adhesions, or a congenital defect such as a uterine septum are detected, they may be corrected at this time through the hysteroscope. The procedure usually takes about 30 minutes. It is performed on an out-patient basis and the recovery time is short, usually the same day.
You should not eat or drink for at least eight hours prior to a hysteroscopy.
