Does Not Having Children Affect Reproductive Health for Women?

Posted by Johnson Memorial Health on Mar 27, 2018

Over the past few decades, experts have debated the impact of not having children on women’s health. Between 1994 and 2014, the percentage of women who had no children by age 44 hovered between 15 and 20%, up from 10% in the 1970s.

The complex issue of not having children also encompasses economic factors, mental health, and lifestyle issues. But what, specifically, does it mean for your reproductive health? Let’s take a closer look.


Pregnancy and Breast Cancer

Research shows that there is a connection between experiencing pregnancy and your lifetime breast cancer risk. A woman’s chance of developing breast cancer is affected by exposure to hormones like endogenous estrogen and progesterone. The changes the body experiences during pregnancy seem to protect the breasts.

While a woman is pregnant, her exposure to certain hormones related to cancer is also reduced. So simply having fewer periods over a lifetime may be a major contributor to reduced cancer risk.

An increased breast cancer risk is associated with being older during a first pregnancy and never having given birth. So, in plain language, you are at a slightly higher risk of breast cancer if you don’t have children.

Other Health Issues

There is some evidence that pregnancy is associated with reduced risk for other health issues too. The reasons aren’t always clear. This is a growing field of research. According to The National Cancer Institute:

  • Women without children may have a higher risk of ovarian cancers.
  • Endometrial cancers are more common in women without children.
  • There may be a connection to uterine tumors.

The Good News

Don’t worry, it’s not all bad news! Not having children also comes with significant positive health benefits. A 116-year study by the American Journal of Human Biology found the following trends.

Longer lifespan. Women with children lost an incredible 95 weeks of life per child carried. Factors are thought to be stress, pregnancy-related diabetes, hypertension, and the nutritional demands of pregnancy and breastfeeding, even in modern industrialized nations.

Improved Health. Education and income are higher among women without children, and these factors have a proven connection to better overall health. It costs more than $230,000 to raise a child to adulthood, so not spending this money can lead to greater wealth and wellbeing.

Protecting Your Reproductive Health

One thing is for sure: Getting good medical care improves your long-term health. Here are some things you can do to promote good reproductive health, whether you have children or not:

Get STD tests. About 19 million people are newly-diagnosed with sexually transmitted diseases each year in the U.S. Many of these STDs have no symptoms, so regular screenings are essential.

Use contraception. Condoms prevent the spread of disease. Birth control pills, IUDs, and other forms of contraception prevent unplanned pregnancy. Both of these situations - disease and unplanned pregnancy - can have challenging consequences for your long-term health.

Avoid drugs and alcohol. Although the connections aren’t crystal-clear, drugs and alcohol seem to contribute to hormone disruption and reproductive issues. They are also linked to STD risk, sexual dysfunction, and reproductive cancers.

Schedule regular checkups. Consistent physicals and gynecological exams bring better lifetime health. They allow doctors to see early warning signs, halt health issues before they worsen, and provide advice that’s backed up by science.
