Common Causes of Infertility

Infertility means that you haven’t been able to conceive after one year of trying to get pregnant or after six months of trying if you’re over 35. While infertility can be upsetting, the truth is that it’s not uncommon. In fact, about 1 in 8 couples experiences fertility issues.

While people often assume the cause of infertility is because of the woman, it is, in fact, just as often an issue with the male partner. One-third of fertility problems are attributed to women, one-third to men, and the last third to either both partners or an unknown cause.

At Women’s Health Care Center, PLLC in Helena, Montana, our expert medical team can provide compassionate care to help diagnose the cause of your fertility problems and help guide you to the right treatment option so that you can build the family of your dreams. Possible causes of infertility include:


Endometrial polyps, also called uterine polyps, are growths that attach to the uterine cavity. These growths are usually not cancerous, but large polyps or multiple polyps can impact fertility and should be removed if you’re having trouble conceiving. 


Endometriosis is a condition in which the cells that normally line the uterine cavity, called the endometrium, grow outside the uterus. About 30% to 40% of women diagnosed with endometriosis have fertility issues.

Ovulation disorders

Ovulation disorders, or the failure to ovulate, is the most common cause of infertility. There are several causes of ovulation failure. Some include thyroid disorders, age and diminished ovarian reserve, and polycystic ovary syndrome (PCOS).

Fallopian tube blockage

When one or both of the fallopian tubes are blocked, the sperm is prevented from fertilizing the egg. Inflammation, infection, fibroids, or polyps can damage or block your fallopian tubes. 

Uterine abnormalities

Uterine abnormalities, which can include polyps in the uterus, fibroids, or the shape of the uterus itself, can also block the fallopian tubes and prevent a fertilized egg from implanting in the uterus. 

Male infertility issues

Many male infertility issues are related to problems with sperm, which can include sperm production, sperm motility, and sperm shape. Another sperm-related male fertility issue is called varicocele. Varicocele is when the veins on a man's testicle are too large, causing it to heat the testicles. Overheated testicles can affect the number or shape of the sperm.
