Have you also lost your fertility for no apparent reason? (Unexplained Infertility) Let's talk about this!
Have you and your husband/wife dreamed of having a baby, but you still haven't been able to make that dream come true? Sometimes, even after doing all the tests, even the doctors can't say for sure, "This is the reason." That's when we talk about this condition called "unexplained infertility." This is really a big burden, but let's talk about it in detail, okay?

What is Unexplained Infertility?

Simply put, unexplained infertility is when there is no clear medical reason for you and your partner's difficulty conceiving. Before you do this, your doctor will run a full series of tests to determine your fertility. Most of the time, these tests will confirm the following:
  • There are no abnormalities or structural problems with your uterus .
  • Ovulation occurs at regular intervals .
  • Your fallopian tubes are not blocked and are open .
  • Your ovarian reserve is good .
  • The hormones needed for reproduction are produced in your brain .
  • Your partner's semen analysis ( sperm count , size, movement, and shape) is completely normal .
Even if all of this is in order, if you're under 35 and haven't been able to conceive for at least a year or six months if you're over 35, then doctors call this "unexplained infertility." Think about it, sometimes when we go to get medicine for an illness, doctors run a bunch of tests, right? This is the same thing. They try everything, but they can't find the root of the problem. It's a little frustrating, but it's not the end of the world.

How common is this condition?

It's hard to say exactly how common this is. Because what one doctor considers "complete" for fertility tests can vary from doctor to doctor. That means there are subtle differences in how tests are performed, so the statistics can be a bit off. One report says that about 10% of couples trying to conceive may have this type of unexplained infertility. That means all of their tests are normal. However, other reports say that this numberIt could be as high as 30% . So, this is not something that is unheard of.

Is it possible to have a baby even with unexplained infertility?

Yes, you can! This is the best news I can give you. Just because you've been diagnosed with "unexplained infertility" doesn't mean you should give up hope. A study by the National Institute of Health (NIH) found that 92% of couples with unexplained infertility went on to have a baby after undergoing fertility treatments. That means there's still a good chance that your dream will come true.
"Unexplained infertility " doesn't mean you can't have a baby. It just means you have to try a little differently.

Is there really no reason? What are the hidden reasons that could be causing this?

Even though it's said that "the cause is unclear," sometimes there really is a cause. However, that cause may be something that can't be measured or detected by current tests. Or, it may be something so subtle that it goes undetected. Let's look at some of the possible reasons:

An underlying, poorly diagnosed medical condition

Researchers are still learning how certain medical conditions affect fertility. For example, Celiac disease (a gluten allergy), diabetes, and thyroid conditions can all affect fertility. You may have one of these conditions, but it may not be fully recognized.

Endometriosis condition

Endometriosis is a condition in which the tissue that normally grows inside the uterus (endometrium) grows outside the uterus. Even in very mild cases, this can sometimes cause infertility. To know for sure whether you have endometriosis or not, you need to have surgery (such as a laparoscopy). Even if you don't have any symptoms, this condition can affect your fertility.

Cervical mucus problems

During ovulation , the cervical mucus helps the sperm meet the egg. If this mucus becomes too thick, or if it contains certain components, the sperm may not be able to pass through the cervix into the uterus.

Egg quality

Doctors can use an ultrasound to look at the follicles in your ovaries and measure how many eggs you have. However, ultrasound cannot tell the quality of those eggs. While blood tests and ultrasound can give you some idea of ​​the quality of your eggs, it is difficult to say for sure.

Sperm quality

Just like in eggs,A semen analysis can detect many problems with sperm. However, sometimes other subtle problems with sperm can also cause unexplained infertility.

Problems with the inner lining of the uterus (Endometrium)

The endometrium is the innermost layer of your uterus. A fertilized egg implants and grows into an embryo in this layer. A luteal phase defect is a condition in which the endometrium is not thick enough or not prepared enough to receive a fertilized egg. If this happens, even if an egg is fertilized, it will not be able to implant in the uterus. Pregnancy will not occur.

Inconsistent timing of sexual intercourse

Sometimes, the frequency of sex, or the timing of sex, may not be in line with your ovulation. This may seem like a small thing, but it can affect your chances of getting pregnant. Sometimes it can happen for no apparent reason, or the cause may be difficult to find or treat. Many things need to go right for a baby to be conceived. If any one little thing goes wrong in that process, the whole thing can go wrong. But the good news is that researchers are always finding new ways to diagnose fertility problems related to things like egg quality, reproductive organ function, and sperm function.

How do you accurately identify this condition?

Not all infertility disorders can be detected with a single test. Also, no test is 100% accurate (for example, very subtle abnormalities may go undetected). According to the American Society of Reproductive Medicine (ASRM), fertility testing should include:
  • Review of complete medical and sexual history .
  • Performing a physical examination .
  • Blood tests to check hormone levels .
  • Examination of your reproductive organs, such as your ovaries, fallopian tubes, and uterus . This may involve an ultrasound or more advanced tests such as a hysterosalpingogram or laparoscopy .
  • Semen analysis of the partner.
  • Ovarian reserve testing.
  • Checking whether your ovulation is happening properly.
If a fertility specialist or obstetrician-gynecologist performs all these tests but cannot find a clear cause, then it is called "unexplained infertility." Keep in mind that each doctor's testing methods may vary slightly. Therefore, if you receive a diagnosis like this, there is nothing wrong with getting a ``second opinion'' from another doctor.

What are the treatments available?

Since your doctor may not be able to pinpoint a single cause for your infertility, he or she will likely recommend treatment based on your fertility test results and his or her experience treating similar couples. In addition, factors such as how soon you want to start treatment and your age will also play a role. The treatments that are often recommended fall into these categories:

Assisted Reproductive Technology (ART)

Assisted Reproductive Technology (ART) is a type of fertility treatment where part of the fertilization process is performed in a laboratory. This includes things like Intrauterine Insemination (IUI) and In Vitro Fertilization (IVF) .
  • In IUI , sperm is washed and concentrated in a laboratory and then inserted directly into your uterus around the time you ovulate.
  • IVF involves creating embryos in the laboratory using your eggs and your partner's (or a donor's) sperm, which are then implanted in your uterus to grow. Often, IVF also involves a procedure called Intracytoplasmic Sperm Injection (ICSI) . This involves injecting a sperm directly into the egg. ICSI can increase the chances of pregnancy when the quality of the sperm is thought to be the cause of unexplained infertility.

Types of drugs

Medications that stimulate ovulation and ovulation are also very useful. These can be used alone or in conjunction with IUI and IVF treatments. The most commonly used medications are gonadotropins and clomiphene (Clomiphene - Clomid®) . Some doctors also prescribe a fertility drug called letrozole (Femara®) , but this is an off-label use. Gonadotropins contain hormones that increase egg production and are also used to treat low sperm counts. Clomiphene also stimulates the ovaries to produce more eggs. Your doctor will recommend the appropriate method based on your situation. However, keep in mind that when using these fertility drugs, more than one egg may be released in a single menstrual cycle. If that happens, there is a greater chance of having more than one baby (like twins).

Lifestyle changes

Some lifestyle habits can affect fertility. Here are some things you can do to increase your chances of conceiving a child:
  • Completely avoid smoking, drinking alcohol, and drug use.
  • Maintain a healthy body weight.
  • Eat a good, balanced diet.
  • Try to exercise for at least 30 minutes a day.
  • Limit caffeine (tea, coffee) intake.
  • Try to reduce your stress .

Be careful about the timing of sexual intercourse.

There is only a very small window of time in your menstrual cycle when you can conceive. Your doctor can help you identify this window. This can be done by tracking your basal body temperature, charting your menstrual cycle, or using ovulation kits . Some doctors may also say, "Just try for a while longer." This can be a difficult treatment plan to understand, especially if you're someone who dreams of starting a family as soon as possible. However, sometimes the problem resolves itself and treatment may not be necessary. However, there's nothing wrong with asking another doctor if you want to, or getting started on fertility treatments sooner rather than later.

Is there a way to prevent this?

While there are things you can do to increase your chances of conceiving a child, there are some factors that we cannot control that affect fertility. Some of the things you can control are:
  • Weight: Maintain a healthy body weight that suits you.
  • Smoking and alcohol: Avoid smoking cigarettes and drinking too much alcohol.
  • Sexual history: Use condoms to protect yourself from sexually transmitted infections (STIs) .
Talk to your doctor about your fertility concerns so he or she can recommend the next steps in your care.

How many couples with unexplained infertility get pregnant?

One study found that about 43% of these people eventually got pregnant without any fertility treatment. That means it can sometimes happen on its own.

What are the important questions to ask your doctor?

It's normal to have a lot of questions when you're diagnosed with "unexplained infertility." The good news is that there's no major problem causing your infertility. The bad news is that your doctor can't tell you exactly why you're not getting pregnant. Talk to your doctor about everything that's on your mind. Ask questions like these:
  • What do you recommend I do next?
  • Which method gives me the best chance of getting pregnant?
  • Are there any blood tests or imaging tests that still need to be done?
  • Could an underlying medical condition be causing my infertility?
  • Should I see a fertility specialist?

How long have you been trying to find a doctor?

Most doctors recommend trying for at least 12 months (a year) before seeking treatment for infertility. However, if you are 35 or older, see a doctor after six months . Your doctor may recommend treatment based on your health history and your desire to have a child.

Finally, things to remember (Take-Home Message)

Unexplained infertility can be a really frustrating and confusing diagnosis. It means that no one can figure out exactly why you can't conceive. But don't worry, or get discouraged - there are treatments to help you. Some couples have success with medication, IUI, or IVF.
"Unexplained infertility" doesn't mean you'll never have a baby. It just means that your doctors will have to try a few different options to help you get pregnant.
Find a doctor who understands your feelings and supports you during this challenging time. Never give up hope. We all wish you the best of luck on your journey to making your dream come true! Infertility, Child Loss, Unexplained Infertility, Fertility, Pregnancy, IVF, IUI
