What is Unexplained Infertility?

Unexplained infertility means that infertility testing has found no clear reason for the couple’s inability to conceive. Doctors typically diagnose unexplained infertility after a year of trying for a baby (or six months for women over 35) and a comprehensive evaluation that includes:

  • Assessment of ovulation and hormone levels for the female partner.
  • Semen analysis for the male partner
  • Tests to check for tubal blockages
  • Evaluation of the uterus for abnormalities

Is it possible to get pregnant despite unexplained infertility?

Yes, it is possible to get pregnant with unexplained infertility, although it can be challenging. A study by the National Institute of Health (NIH) showed that 92% of couples with unexplained infertility who received fertility treatment had a child.

Symptoms and Causes:

Symptoms of unexplained infertility:

  • Inability to Conceive: Couples may experience difficulty getting pregnant despite regular, unprotected intercourse for at least a year (if the woman is under 35) or six months (if the woman is over 35).
  • Normal Menstrual Cycles: Regular menstrual cycles without any abnormalities in terms of duration, flow, or frequency.
  • Normal Semen Analysis: The male partner typically has normal sperm parameters as assessed through semen analysis.
  • Normal Ovulation: The female partner ovulates regularly, as confirmed through tests like basal body temperature charting, ovulation predictor kits, or blood tests measuring hormone levels.

Causes of unexplained infertility:

Ovulatory Dysfunction:

Ovulatory Dysfunction

While ovulation may seem normal, subtle irregularities in ovulation can still occur, leading to unexplained infertility. These irregularities may not be detected through standard tests.

Fallopian Tube Abnormalities:

fallopian tube abnormalities unexplained infertility

 Structural issues with the fallopian tubes, such as blockages or damage, can interfere with the fertilization process despite appearing normal on imaging tests.

Uterine Abnormalities Uterine:

Conditions like endometriosis, uterine fibroids, or polyps might affect fertility without causing significant symptoms.

Immunological Factors:

The immune system may play a role in fertility, with conditions like autoimmune disorders potentially impacting fertility outcomes.

Subtle Hormonal Imbalances:

Minor hormonal imbalances that are not detected through routine tests may affect the delicate hormonal balance necessary for conception.

Sperm Function Abnormalities:

Sperm Function Abnormalities Unexplained Infertility

Although semen analysis results may fall within normal ranges, there could be undetected issues with sperm function, such as poor sperm motility or sperm DNA damage.

Poor Egg Quality:

While ovarian reserve may appear normal, egg quality can still be compromised, impacting fertilization and embryo development.

Sperm-egg Interaction:

Sperm-egg Interaction for Unexplained Infertility

 Issues with the interaction between sperm and egg during fertilization, such as difficulty penetrating the egg’s outer layer, could contribute to unexplained infertility.

Lifestyle Factors:

Factors like stress, excessive alcohol consumption, smoking, or poor diet may affect fertility without being identified as the primary cause.

Diagnosis and Tests

How is unexplained infertility diagnosed?

Unexplained infertility is diagnosed when a couple experiences difficulty conceiving without any identifiable cause after undergoing a thorough evaluation. According to the American Society of Reproductive Medicine (ASRM), fertility testing should include these steps:

  • Medical History and Physical Examination
  • Blood tests to look at hormone levels
  • Ovarian reserve testing
  • Genetic testing
  • Transvaginal Ultrasound
  • Semen Analysis Hysterosalpingography (HCG)
  • Ovulation Assessment

Treatment for unexplained infertility:

Diagnosis: – ERFA- Soil Testing:

ERFA testing results in a complete endometrial receptivity and function analysis, assessing multiple endometrial biomarkers at the time of the “window of implantation”.

Lifestyle Changes:

 Sometimes simple lifestyle changes can improve fertility. These may include maintaining a healthy weight, quitting smoking, reducing alcohol intake, and managing stress.

In Vitro Fertilization (IVF):

 IVF is often the next step if simpler treatments like medication and IUI have failed.In this procedure, sperm and eggs are fertilized in the laboratory and then the embryos are transferred to the uterus.

 IVF can also involve additional techniques like intracytoplasmic sperm injection (ICSI) if there are male factor infertility issues.


In some cases, surgical procedures such as laparoscopy or hysteroscopy may be recommended to address underlying issues such as endometriosis, uterine fibroids, or blocked fallopian tubes.

Fertility Medications:

Medications like Clomiphene citrate (Clomid) or letrozole (Femara) can help induce ovulation in women. In some cases, these medications may be combined with intrauterine insemination (IUI) to improve the chances of conception.

Intrauterine Insemination:

In the IUI process, the sperm is placed directly into the uterus at the time of ovulation. This bypasses potential problems with sperm motility or cervical mucus and increases the chances of fertilization.

Preimplantation Genetic Testing (PGT):

or couples undergoing IVF, PGT can be used to screen embryos for genetic abnormalities before implantation, potentially increasing the chances of a successful pregnancy.

Alternative Therapies:

Some couples explore alternative therapies such as acupuncture, herbal supplements, or traditional Chinese medicine to improve fertility. While these may not have conclusive scientific evidence, some individuals find them helpful.

Counseling and Support:

Dealing with unexplained infertility can be emotionally challenging. Counseling provides emotional support and courage to cope.

It’s essential for couples experiencing unexplained infertility to work closely with a fertility specialist to explore the most appropriate treatment options based on their unique situation and preferences. Additionally, seeking emotional support throughout the process can be beneficial.

Is there a way to prevent unexplained infertility?

  • Maintain a Healthy Lifestyle: Maintain a balanced diet, regular exercise, manage stress, and avoid harmful habits like smoking and excessive alcohol to support fertility in the case of unexplained infertility.
  • Seek Timely Evaluation:Seek timely evaluation from a fertility specialist to identify potential underlying causes and explore appropriate treatment options for unexplained infertility.
  • Limit Exposure to Environmental Toxins
  • Educate Yourself
