Cervical Factor Infertility
The cervix is an extension of the lower uterus which protrudes into the vaginal vault. As such, it serves as the gateway into the uterine cavity from the vagina. Sperm ejaculated in the vagina during sexual intercourse must traverse the cervix before entering the uterus. The cervix is lined with glandular tissue which secretes cervical mucus responsible for facilitating the passage of sperm through the cervix. Therefore, abnormalities in the cervix or cervical glands may impede the entry of sperm into the uterus and contribute to infertility.
Cervical factor may occur secondary to the intake of certain medications, cervical or uterine surgery, congenital anomalies, and unexplained factors. Diagnosing cervical factor infertility begins with a comprehensive medical history, which can often determine whether risk factors for cervical factor exist. In the recent past, testing for cervical factor used to include the post coital test, which assessed the behavior of sperm within cervical mucus. Inaccuracies and inconsistencies in the post coital test led to the abandonment of such testing. Today, assessing cervical factor is performed using transvaginal ultrasonography and mock embryo transfers, which can often reveal whether a significant abnormality exists within the cervix.
Treatment for mild cervical factor often involves intrauterine insemination (IUI/artificial insemination) of sperm. This simple technique facilitates the passage of sperm into the uterine cavity by bypassing the cervix and depositing sperm through the cervix directly into the top of the uterine cavity. Severe cervical factor infertility (severe cervical stenosis/stricture, absent cervix) can often be treated with in vitro fertilization and laparoscopic GIFT or ZIFT.
FAQ
Reproductive endocrinology and Infertility is a sub-specialty of Obstetrics and Gynecology. In addition to managing medical and surgical treatment of disorders of the female reproductive tract, reproductive endocrinologist and infertility (REI) specialists undergo additional years of training to provide fertility treatments using assisted reproductive technology (ART) such as in vitro fertilization.
Reproductive endocrinologists receive board certification by the American Board of Obstetrics and Gynecology in both Obstetrics and Gynecology and Reproductive Endocrinology and Infertility.
In general, patients should consider consulting with an REI specialist after one year of trying unsuccessfully to achieve pregnancy. The chance of conceiving every month is around 20%, therefore after a full year of trying approximately 15% of couples will still not have achieved a pregnancy.
However, if a woman is over the age of 35 it would be reasonable to see a fertility specialist earlier, typically after 6 months of trying.
Other candidates to seek earlier treatment are women who have irregular menses, endometriosis, fibroids, polycystic ovary syndrome (PCOS), women who have had 2 or more miscarriages, or problems with the fallopian tubes (prior ectopic pregnancy).
Approximately 1/3 of the time cause for infertility is a female factor, 1/3 of the time a male factor, and the remaining 1/3 a couples’ factor.
At CCRH, we emphasize the importance of establishing a correct diagnosis. Both partners undergo a comprehensive evaluation including a medical history and physical exam.
Furthremore, the woman’s ovarian reserve is assessed with a pelvic ultrasound and a hormonal profile. A hysterosalpingogram (HSG) will confirm fallopian tube patency and the uterine cavity is free of intracavitary lesions. A semen analysis is also obtained to evaluate for concentration, motility, and morphology of the sperm.
Additional work up is then individualized to direct the best possible treatment option for each couple.
In vitro fertilization (IVF) is the process that involves fertilization of an egg outside of a woman’s body.
The process starts with fertility drugs prescribed to help stimulate egg development. In your natural cycle, your body is only able to grow one dominant egg, but with stimulation medication we can recruit multiple eggs to continue to grow. After about 8-10 days of stimulation, the eggs are surgically retrieved and then fertilized with sperm in a specialized laboratory. Fertilized eggs are then cultured under a strictly controlled environment within specialized incubators in the IVF laboratory for 3-5 days while they develop as embryos. Finally, embryos (or an embryo) are transferred into the uterine cavity for implantation.
Before deciding if IVF is the right choice, it’s important to sit down with an REI specialist to discuss available treatment options. For some people, other methods such as fertility drugs, intrauterine insemination (IUI) may be the best first choice treatment. At CCRH, we believe each individual couple is unique and not everyone needs IVF.
While not painful, the fertility medications may some side effects including headaches, hot flashes, mood swings, and bloating. The injection sites may also bruise.
Unfortunately, no. Many people think once they start IVF it’s a matter of time that they will be pregnant and have a baby. But according to national statistics per the Society of Assisted Reproduction (SART), on average 40% of assisted reproduction cycles achieve live births in women under age 35. The chances of success then continue to decrease with advancing age.
At CCRH, we employ only evidence-based interventions to ensure patient safety and optimal outcome. While we cannot guarantee a baby, we guarantee that you will receive the best, most advanced, personalized care to help you maximize your chance of a baby.
The average IVF success rate (success measured in live birth rate) using one’s own eggs begins to drop around age 35 and then rapidly after age 40. This is due to the decline in egg quantity and egg quality as a woman ages.
Our clinic’s success rate consistently beats the national average year after year.
Individual insurance plans often do not have any coverage for infertility treatments. If you have a group plan, you can call members services to see if they have coverage for infertility (including consultation/workup and IVF).
