Unexplained Infertility: Causes And Treatment Options

Unexplained infertility is defined as infertility where the male and female fertility tests are otherwise normal, and the couple is unable to conceive despite regular and unprotected intercourse. Unexplained infertility can be upsetting and confusing, as no medical reason is found for infertility. Although ovulation, sperm function, and reproductive organs appear normal, subtle problems may be the reason for conception to be a problem.

Egg quality or sperm function and fertilization or implantation may not be performing well, even though it seems normal. Knowing the causes of unexplained infertility is beneficial,l as the correct treatment can then be selected. With correct diagnosis, lifestyle modification, and medical intervention, many couples can achieve pregnancy successfully.

What Is Meant By Unexplained Infertility?

The definition of unexplained infertility is when a couple is unable to get pregnant, with both partners performing the appropriate standard tests for infertility. The diagnosis is made when a couple can complete all of the standard testing for infertility, which includes ovarian assessment, including ovulation, the egg supply, uterine anatomy, and fallopian tube patency for the female, as well as semen analysis for the male.

In the case of unexplained infertility, there is no identifiable medical reason as to why the couple cannot get pregnant. Generally, a diagnosis of unexplained infertility is made when a couple has been actively trying to conceive for a minimum of one year or six months if the female is older than the age of 35.

There is no known reason for infertility, but pregnancy can often be achieved by lifestyle changes, the use of ovulation induction drugs, or Intra Uterine Insemination (IUI) or In Vitro Fertilization (IVF).

Prevalence And Probability Of Conception With Unexplained Infertility

Unexplained infertility is estimated at different rates as well, due to differences in how patients are evaluated as fertile, depending on their physician. It is believed that approximately 10 percent of all couples seeking to become pregnant will present with normal results to fertility testing with no apparent cause, but other estimates place that figure at nearly 30 percent.

Regardless, pregnancy is still quite achievable with unexplained infertility. Infertility testing indicates that approximately 92 percent of couples with unexplained infertility who are provided adequate fertility treatments will conceive. This does not have to mean the end of the road, and with proper care and treatment of this issue, many will become parents.

Causes Of Unexplained Infertility

1. Hidden Medical Conditions

Sometimes, certain conditions such as diabetes, thyroid dysfunction, and autoimmune disorders cause fertility problems, yet they are undiagnosed during routine investigations.

2. Mild Endometriosis

Minimal or subclinical endometriosis is also known to adversely affect egg implantation and fertilization, but may be undiagnosed even at investigations, unless examined during surgery.

3. Abnormal Cervical Mucus

Subtle changes in the physical properties and composition of cervical mucus can prevent the fertilization of the egg by the sperm

4. Poor Egg Quality

Ovarian reserve is estimated, but not precisely egg quality. Minor defects in egg development might affect the fertilization of the egg or the development of the embryo, which is still unmeasurable by standard investigations.

5. Sperm Function Abnormalities

Although semen analyses may be normal, there may be functional defects present in the sperm.

6. Uterine Lining Defects

Inadequate formation of the uterus lining, called the endometrium, may prevent the fertilized egg from implanting.

7. Hormonal Imbalances

Subtle changes in hormone levels might cause either a lack of ovulation or prevent implantation, which may not be noticeable during normal testing.

8. Optimal Time Of Intercourse Not Met

Failure of timely intercourse relative to the timing of ovulation would decrease pregnancy chances, although no apparent pathology would be found.

In the majority of cases of unexplained infertility, it may be due to subtle or multiple issues, which are presently impossible to identify.

Treatment Options For Unexplained Infertility

1. Assisted Reproductive Technology (ART)

ART procedures where fertilization is undertaken outside the body. IUI requires sperm to be inserted into the uterus during a period of ovulation, with the intention of increasing the probability of conception.

In vitro fertilisation involves combining eggs and sperm within a laboratory environment for fertilisation, followed by insertion into the uterus. Procedures such as intra-cytoplasmic sperm injection (ICSI) are sometimes performed to assist with fertilization if subtle issues relating to the sperm are present.

2. Fertility Medications

Fertility medications, such as clomiphene, letrozole, or gonadotrophins, are sometimes used to stimulate ovulation and increase the production of eggs, which are then inserted into the body in conjunction with an IUI or IVF procedure.

3. Lifestyle Modifications

Generally, healthy lifestyles can contribute positively towards fertility, such as regular exercise, a balanced diet, a healthy weight, decreased levels of stress, and abstention from smoking and/or alcohol.

4. Tracking The Fertile Period

By monitoring ovulation, whether it be via cycle charts, basal body temperature tracking, or using an ovulation test kit, the probability of a natural pregnancy can be increased.

5. Expectant Management

Some health professionals encourage expectant management where the couple is advised to continue trying for pregnancy on their own, as some natural conception occurs over time with or without treatment.

When To Consult A Doctor?

• When you have been trying to get pregnant for 12 months (if under 35).
• When you are 35 years old and are unable to get pregnant within 6 months.
• Irregular, missed, or painful periods.
• Existing diagnosed disorders such as PCOD, endometriosis, thyroid disorder, etc.
• Repeated history of miscarriage.
• History of any pelvic infection or surgery involving reproductive organs.
• Confirmed problems with the male partner and his sperm and health history.
• Trouble timing ovulation and tracking fertile days.
• Any unexplained pelvic pain and abnormal symptoms.

Early medical advice and treatment will be of assistance and offer better chances of successful conception.

Final Thoughts

A fertility problem can seem frustrating when there is no definitive answer, but this does not signify an end to the hope of conception. With appropriate medical treatment, life adjustments, and support, most couples go on to achieve pregnancy.

2. What is the chance of pregnancy with unexplained infertility?

Per cycle pregnancy rates are around 10% to 20% in the general population and depend upon age, duration of infertility, and mode of treatment.

3. If the tests all come back normal, why is there a problem of unexplained infertility?

Possible causes, but not limited to, are sub-microscopic problems of egg and/or sperm function, fertilization, or implantation.

4. What part does age play in the chances of pregnancy in unexplained infertility?

Older maternal age has a detrimental effect on the chances of conception, it has a role in depletion of the ovarian reserve and poor quality of egg, and subsequent impact on implantation chances.
