What Causes Female Infertility?

There are multiple causes of infertility in men and women. Amongst the reasons are age, sexually transmitted diseases, reproductive system disorders, history of smoking and/or drinking, pre-conception weight, healthcare habits, and more.

Signs of Infertility in Women

Amongst the number of women in the United States within reproductive age range, close to 12% are impacted by infertility.


One of the primary factors in female infertility is age. Women have a 1:4 probability of becoming pregnant when they are in their mid-20s. Over the course of fifteen years, there is a steep decline in probability. By the age of 40, the chance of pregnancy, on average, is about 8%.

But there are women who naturally conceive when in their thirties and forties, so do not be discouraged. You may simply need to work more closely with your physician and become aware of the possibility that it may take a little longer to conceive.


Ovulation disorders are also a common cause of infertility. Ovulation, which is the natural process of mature eggs moving down the fallopian tube in preparation for fertilization, is a system that can malfunction in some way.

Problems with ovulation are complex. Some contributing factors are: diabetes, thyroid disorders, issues with the adrenal glands, obesity, excessive exercise, diabetes, stress, and extreme weight loss.

Addressing these contributing factors may help to regulate your menstrual cycle, which increases one's chance of becoming pregnant.

Polycystic Ovarian Syndrome

When follicles that should release bunch up instead, forming cysts, this condition is called polycystic ovarian syndrome, or PCOS. Considered one of the leading causes of infertility, PCOS is bring about by a hormonal imbalance and is characterized by: obesity, excess body hair, and irregular menstrual cycles. In this condition, eggs are not released or fertilized by sperm – preventing pregnancy.

Our bodies are fragile and, often times, there is no “infertility formula.” If you feel that one of these conditions have posed a challenge to your pregnancy efforts, contact your physician in order to design a fertility plan that best addresses your bodily needs.

Sexually Transmitted Diseases

Contracting sexually transmitted diseases (STDs) can also cause infection and/or scarring in the reproductive system, inhibiting pregnancy. Pelvic Inflammatory Disease (PID) can cause infection in a woman’s ovaries, fallopian tubes, pelvis, cervix, or uterus. PID infections are most commonly caused by STDs, such as, chlamydia, gonorrhea, or genital herpes. But its inception can also stem from bacterium that travels through lymphatic disorders, intrauterine devices, blood, and other sources.

Fibroid Tumors

Experiencing the pains of fibroid tumors? Fibroids may also cause infertility. Although they are non-cancerous, they bring about painful menstrual periods, heavy menstruation, frequent and urgent urination, and they can cause pain during sexual intercourse.

Large-sized fibroids can obstruct the fallopian tubes and when these benign tumors are located in the lining of the uterine wall, these are grounds for infertility.

As you can see here, there are multiple reasons why women are faced with complications when trying to conceive. Fortunately, a high percentage of these causes are treatable.
