So, you’ve been trying to get pregnant for a while, but nothing is happening. Why are you not getting pregnant? There are many possible reasons, including ovulation irregularities, structural problems in the reproductive system, low sperm count, or an underlying problem.

While infertility can have symptoms like irregular periods or severe menstrual cramps, the truth is that most causes of infertility are silent.

Male infertility rarely has symptoms. Here are possible reasons you haven’t conceived yet.

YOU HAVEN’T BEEN TRYING FOR LONG ENOUGH

The first thing to consider is how long have you been trying. It may feel like you’ve been trying forever and maybe you have! but it’s important to know that many couples won’t conceive right away.

About 80 percent of couples conceive after six months of trying. Approximately 90 percent will be pregnant after 12 months of trying to get pregnant. This assumes you have well-timed intercourse every month.

See a specialist about your fertility if

• You’re 35 years or older and have been trying for at least six months
• You’re younger than 35 and have been trying for at least one year

If either of these fit your situation then see us, even if you have no symptoms of a fertility problem.

YOU’RE NOT OVULATING

Human conception requires an egg and sperm.

If you’re not ovulating, you won’t be able to get pregnant.

Anovulation is a common cause of female infertility and it can be triggered by many conditions. PCOS is one possible cause of anovulation. Other possible causes include being over or underweight, primary ovarian insufficiency, a thyroid dysfunction, hyperprolactinemia, and excessive exercise.

Most women who are experiencing ovulation problems have irregular periods. However, regular menstrual cycles don’t guarantee that ovulation is occurring.

THE PROBLEM IS WITH HIM, NOT YOU

Women may carry the baby, but it takes two to tango. Twenty to 30 percent of infertile couples discover fertility factors on the man’s side. Another 40 percent find infertility factors on both sides.

Another thing you need to know: male infertility rarely has symptoms that are observable without a semen analysis, which is a test that measures the health of the semen and sperm.

AGE-RELATED INFERTILITY IS CAUSING A PROBLEM

For women after age 35, and for men after age 40, it can take longer to get pregnant.

Some women assume if they still get regular periods their fertility is fine, but this isn’t true. Age impacts egg quality as well as quantity.

Also, if your partner is five or more years older than you are, this can further increase your risk of fertility problems after age 35.

YOUR FALLOPIAN TUBES ARE BLOCKED

Irregular ovulation accounts for 25 to 30 percent of female infertility cases.

The rest can have problems with blocked fallopian tubes, uterine structural problems, or endometriosis.

In case you don’t know, the fallopian tubes are the pathway between your ovaries and the uterus. The fallopian tubes do not directly attach to the ovaries. Sperm must swim up from the cervix, through the uterus, and into the fallopian tubes. When an egg is released from the ovaries, hair-like projections from the fallopian tube draw the egg inside. Conception takes place inside the fallopian tube, where the sperm and egg finally meet. If anything prevents the fallopian tubes from working properly, or if scarring blocks the sperm or egg from meeting, you won’t be able to get pregnant.

There are many possible causes of blocked fallopian tubes. While some women with blocked tubes experience pelvic pain, many others have no symptoms. Only fertility testing can determine if your tubes are open. An HSG is a specialized X-ray used to determine if your fallopian tubes are open.

YOU HAVE ENDOMETRIOSIS

Endometriosis is when endometrium-like tissue (which is the tissue that lines the uterus) grows in places outside of the uterus. It’s estimated that up to 50 percent women with endometriosis will have difficulty getting pregnant.

The most common symptoms of endometriosis include painful periods and pelvic pain at times besides menstruation. However, not all women with endometriosis have these symptoms. Some women who discover they have endometriosis as part of an infertility work-up.

Endometriosis is commonly misdiagnosed or simply just missed. Endometriosis can’t be diagnosed with a blood test or ultrasound.

UNEXPLAINED INFERTILITY

Between 25 to 30 percent of infertile couples never find out why they can’t get pregnant. Some say this is a lack of good diagnosis. They say there is no such thing as unexplained infertility but only undiscovered or undiagnosed problems.

The fact remains, though, that some couples don’t get answers. However, not having answers doesn’t mean you can’t be treated. You can (and should) still receive treatment for infertility even if your diagnosis is unexplained.
