Fertility issues affect millions of couples worldwide, but what happens when doctors can't pinpoint a specific cause? This is the challenge many face with unexplained infertility, a condition where despite extensive testing, no clear reason for infertility is found. If you are experiencing this, you’re not alone—approximately 10-20% of couples struggling to conceive are diagnosed with unexplained infertility.
At New World Fertility, we understand the frustration and confusion that come with this diagnosis. In this blog, we'll break down what unexplained infertility is, explore potential causes, and discuss the treatment options available to those affected.
What is Unexplained Fertility?
Unexplained fertility is a diagnosis given when a couple has been unable to conceive after a year of regular, unprotected sex, and all tests—including hormone levels, semen analysis, ovulation tracking, and fallopian tube assessments—come back normal. Despite these results, conception still hasn’t occurred, leaving both partners in a state of uncertainty.
While it may sound daunting, it’s important to know that unexplained infertility is not an end to your fertility journey. It simply means that modern medicine hasn’t yet pinpointed the exact cause, but there are still options to help you conceive.
Potential Causes of Unexplained Infertility
Although the cause is not identifiable with current testing methods, many experts believe that unexplained infertility could stem from several possible factors, including:
1. Subtle Ovulation Issues
Even though a woman may be ovulating, it’s possible that her egg quality is not optimal or that ovulation is happening later than expected. These subtle issues can affect the timing of conception.
2. Sperm Quality or Function
Semen analysis might show normal sperm count, but sperm quality can still be an issue. This includes factors like sperm motility (ability to swim), morphology (shape), or DNA fragmentation, all of which can contribute to infertility.
3. Endometriosis or Mild Tubal Disease
Sometimes, mild endometriosis or blocked fallopian tubes may not show up in standard tests but still impact fertility. Endometriosis, a condition where tissue similar to the uterine lining grows outside the uterus, can affect the egg's ability to travel through the fallopian tubes or implant properly.
4. Immune System Factors
In some cases, the immune system may be producing antibodies that negatively affect the sperm, egg, or embryo. These immune-related issues can be difficult to detect with traditional testing.
5. Lifestyle Factors
External factors, such as stress, diet, smoking, or excessive alcohol use, could also contribute to fertility issues. Even though these factors might not show up in basic fertility tests, they could still play a role in conception.
6. Age-Related Factors
As women age, the quality of their eggs declines, and the chances of successful conception reduce. Even if tests don’t show obvious fertility issues, the age factor can still be a significant contributor to infertility.
How is Unexplained Fertility Diagnosed?
A diagnosis of unexplained infertility typically involves a thorough evaluation. The following tests are commonly conducted:
Ovulation Testing: Monitoring hormone levels and using ovulation predictor kits to ensure ovulation is happening regularly.
Semen Analysis: Evaluating sperm count, motility, and morphology to assess male fertility.
Hysterosalpingography (HSG): A special X-ray test to check if the fallopian tubes are open and the uterus is normal.
Hormonal Assessments: Checking levels of hormones like FSH, LH, estrogen, and progesterone to gauge ovulatory function and overall reproductive health.
Ultrasounds: Monitoring the ovaries and uterus to detect any abnormalities, such as cysts or fibroids.
If all tests come back normal, and conception doesn’t occur after a year of trying, you may receive the diagnosis of unexplained infertility.
What Are Your Treatment Options?
Even though the cause of unexplained infertility is unclear, several treatment options can increase your chances of conception. These include:
1. Intrauterine Insemination (IUI)
IUI involves placing specially prepared sperm directly into the uterus around the time of ovulation. This procedure increases the number of sperm that reach the egg and can be combined with ovulation-stimulating medications to improve the chances of success.
2. In Vitro Fertilization (IVF)
IVF is one of the most common treatments for unexplained infertility. In IVF, eggs are retrieved from the ovaries, fertilized in a lab with sperm, and then the embryos are transferred into the uterus. IVF bypasses many potential issues that could prevent natural conception, offering a high success rate for couples with unexplained infertility.
3. Ovulation Stimulation
In some cases, medications like Clomid or gonadotropins can be used to stimulate ovulation. These medications can increase the chances of releasing multiple eggs, which can enhance the likelihood of conception.
4. Lifestyle Changes
Improving your diet, exercise habits, and reducing stress can positively impact your fertility. Avoiding smoking, excessive alcohol, and other toxins also contributes to better reproductive health.
5. Advanced Fertility Techniques
For couples struggling with unexplained infertility, techniques such as genetic screening and embryo freezing may offer additional options. These procedures provide more in-depth insights into the genetic health of embryos, improving the chances of a healthy pregnancy.
Success Rates for Unexplained Infertility Treatment
According to the American Society for Reproductive Medicine (ASRM), about 60-70% of couples with unexplained infertility will eventually conceive with the help of assisted reproductive technologies like IUI or IVF. Success rates are influenced by various factors, including the woman’s age, the quality of the sperm, and the specific treatment used.
IUI Success Rate: The success rate for IUI ranges from 5% to 20% per cycle, depending on factors such as age and the cause of infertility.
IVF Success Rate: IVF success rates typically range from 40% to 50% per cycle for women under 35, but success rates decrease with age, particularly after 40.
While these numbers offer hope, it’s important to remember that every couple’s fertility journey is unique. The process may take time, but persistence, coupled with expert care and guidance, can lead to success.
Emotional Support During the Journey
Navigating unexplained infertility can be emotionally taxing. The lack of answers can lead to feelings of frustration, isolation, and stress. It’s important to seek support, whether through counseling, support groups, or friends and family. Managing stress and maintaining a positive outlook can be just as crucial as medical treatment in achieving a successful pregnancy.
