Lack of knowledge among women concerning fertility after 35

fertility declines with age

In a recent article in the Washington Times, Janice Shaw Crouse presented an overwhelming concern regarding a lack of knowledge among women concerning their window of fertility.

Crouse went on to explain that attaining an understanding of women’s biological clock is perhaps more important than ever concerning a number of political and cultural factors. Exactly what reproductive research has been telling us for years!

For example, there is significant pressure on women to put off having children until other aspects of their lives are “complete.” This includes a renewed early focus on establishing a career.

The result is that women are increasingly putting off marriage until their late 20’s or 30’s and putting off having children until mid 30’s and beyond. While developing a career is certainly very important for many women, a significant amount of the population do not realize that putting off having children to later in life may leave them with extreme difficulty conceiving.

Women should be better informed about fertility

It is essential that women receive accurate information regarding this window of fertility so that they can proactively consider the options that revolve around their life choices.

Perhaps the best way to provide women with this information is to begin by simply explaining the basic processes behind fertility.

Unlike men who continually create sperm, a woman is born with every egg-containing follicle that she will ever have.

According to the American Society for Reproductive Medicine, a woman will have about one million follicles at birth. By the time she reaches puberty, the number will have decreased to 300,000. During the monthly cycle, the pituitary gland in the brain releases a hormone called follicle-stimulating hormone (FSH), which causes some of the follicles to grow.

Generally, only one follicle each month will become a lead follicle and release its egg during ovulation. During her reproductive years, a woman will release approximately 300 eggs through ovulation. The rest of the follicles will degenerate and go away.

fertility declines with ageAdditionally, fertility decreases as women age. According to a study of nearly 1,000 couples in partnership between the University of North Carolina and Italy’s University of Padua, women are ten percent less fertile by age 27.

Another significant drop in fertility is noted at age 35 and the rates continue to go down significantly into the 40’s. For women over 35 seeking to become pregnant, it is important to realize that this information does not mean they are unable to become pregnant. It just means that it may take a longer time.

For those having significant difficulties, there are a number of natural as well as medical options available to increase the odds. However, for many women, a significant problem is the lack of knowledge about age-related decreases in fertility paired with a social culture preaching putting off having children.

It is certainly true that the pattern of women waiting later to have children can be readily seen.

For example, the rate of birth in the US has declined from 127 births per 1,000 women in 1909 to 63 births per 1,000 women in 2012, the lowest rate to date. In many countries in Europe, there is actually negative population growth at the moment.

For some women, waiting later in life to have children fits their personal goals. They value having more time to establish careers, explore the world, spend quality one-on-one time with their partner, or a number of other things. However, for those who are certain that they want to have children, it is important to consider the risks versus rewards of waiting to later in life.

According to the American Pregnancy Association, there are a number of reasons why women may have difficulty conceiving after age 35.

The most common is simply the less frequent ovulation that comes with age. However, other reasons can include medical issues such as endometriosis, fibroids, or growth of scar tissue in the fallopian tubes. Other chronic health issues such as high blood pressure of diabetes can also contribute to problems.

Researchers have found that miscarriage is also more common with women over 35 and occurs in 20-35 percent of pregnancies at that age.

According to the Centers for Disease Control and Prevention, women over 35 also have a higher risk of babies born with low birth rate or a number of chromosome related birth defects such as Down’s syndrome.

The reality is that having children is an amazing process regardless of age. This is evidenced by the amount of publicity given to births. The media is filled with stories about babies and particular attention is paid to celebrities who give birth past age 40.

However, amidst these stories of happiness and glamour, it is essential for women to understand the science and statistics around fertility so that they can make the choices they feel best for their life.
