Can unexplained infertility get pregnant?

Couples diagnosed with unexplained infertility take longer to find treatment and conceive.

Unexplained infertility is infertility after tests show no clear cause for fertility problems.

Typically, the test results will reveal: no uterine abnormalities or structural problems with the woman's uterus; regular ovulation; clear fallopian tubes; a good number of eggs; a normal male semen analysis (quantity, quality, motility, and shape). Those diagnosed have been trying to get pregnant for at least a year if the couple is under 35 or 6 months if they are 35 or older, without success.

Doctors have a hard time figuring out what causes this condition. However, some issues that may contribute to unexplained infertility include:

Age: A common culprit in decreasing pregnancy rates, especially in patients over 35, is age. Many people have great difficulty conceiving in their 30s.

Irregular menstrual cycles: Most couples can get pregnant after trying for a year if the woman has regular menstrual cycles. However, when the cycle is irregular, it can be difficult for doctors to determine the "golden moment" for the egg and sperm to meet and conceive.

Low Fertility: Some individuals or couples are diagnosed with low fertility by their doctors and it takes them longer to successfully conceive.

An underlying undiagnosed condition: Celiac disease (gluten allergy), diabetes, and thyroid disease can potentially cause infertility.

Mild endometriosis: Mild or asymptomatic endometriosis can also contribute to infertility.

Abnormal uterine lining : The endometrium is the lining of the uterus, where the embryo implants and grows during pregnancy. When the endometrium fails to thicken or prepare itself for a fertilized egg, it is called a luteal phase defect. This means that even if the egg is fertilized, it cannot implant, and the woman cannot become pregnant.

Cervical mucus: Cervical mucus helps sperm swim easily to meet the egg during ovulation. If the cervical mucus is thick or contains certain ingredients, sperm may not be able to pass through the cervix to reach the uterus.

Low egg quality: Doctors can measure the number of eggs by using an ultrasound of the follicles in the ovaries. But the ultrasound does not tell them about egg quality. Blood tests and ultrasounds can give clues about egg quality, but they are not a definitive diagnosis.

Poor sperm quality: Similar to egg quality, sperm analysis reveals most sperm problems. But other problems with sperm can arise and contribute to unexplained infertility.

Intercourse at the wrong time: Frequency or timing of intercourse that is not in line with ovulation also makes it difficult for women to get pregnant.

No fertility test can diagnose all infertility problems, and testing methods are not 100% accurate. The American Society for Reproductive Medicine (ASRM) says fertility testing typically includes: medical and sexual history; physical examination; blood tests to look at hormone levels; evaluation of the reproductive organs (ovaries, fallopian tubes, and uterus); semen analysis...

Many conditions are necessary to conceive, and many conditions can disrupt the process. Fertility treatments such as intrauterine insemination (IUI) and in vitro fertilization (IVF) can be used. A study from the National Institutes of Health (NIH) found that 92% of couples with unexplained infertility were able to conceive with fertility treatment.

Experts advise people struggling with unexplained infertility to take active care of their health to increase their chances of successful conception, such as: taking pre-pregnancy vitamins; exercising regularly; getting 8 hours of sleep each night; eating a healthy, scientific diet to maintain a healthy weight; limiting smoking and drinking; reducing stress... and improving intercourse time.
