7 Fertility Facts Every Woman Should Know About Reproductive Health
Updated: Oct 18
Fertility can sometimes feel like a mystery, especially when you are surrounded by advice, myths and stories from other people's experiences.
The truth is that fertility is personal. What happens for one woman may look completely different for another. Understanding a few basic facts can help you make informed decisions about your reproductive health.
Your Fertile Window Is Limited
Pregnancy is most likely to happen around the time of ovulation.
The fertile window is generally considered the six days ending on the day of ovulation. This is because sperm can remain viable for several days, while an egg has a much shorter window in which it can be fertilized.
Knowing when you may ovulate can therefore be helpful if you are trying to become pregnant.

Regular Periods Can Offer Useful Clues
Your menstrual cycle can tell you quite a bit about your reproductive health.
Regular cycles often suggest that ovulation is occurring, although a regular period does not guarantee fertility.
Very irregular periods, missed periods or unusually short cycles can sometimes indicate that ovulation is not happening regularly. If your periods are consistently irregular, it is worth discussing this with your healthcare provider.
Age Is One Piece of the Picture
Fertility generally declines with age, and the change becomes more noticeable as women get older.
However, age is only one part of fertility. Your reproductive history, ovulation, fallopian tubes, uterus and other health factors can also matter.
This is one reason fertility advice should be personal rather than based entirely on someone else's experience.
Your Lifestyle Matters Too
Healthy habits support your overall wellbeing while preparing for pregnancy.
Eating a balanced diet, exercising regularly, getting adequate sleep and avoiding smoking and recreational drugs are all useful steps.
If you drink alcohol or use caffeine, talk with your healthcare provider about what is appropriate while trying to conceive. ASRM recommends limiting alcohol and caffeine to minimal or moderate amounts while attempting pregnancy.
Fertility Testing Is Not Always Necessary
It can be tempting to use an at-home fertility test or request blood work simply to find out whether pregnancy will be easy or difficult in the future. However, no single test can provide that certainty.
Ovarian reserve tests, including anti-Müllerian hormone (AMH) testing, can help fertility specialists understand how the ovaries may respond to certain treatments. They are not reliable stand-alone predictors of whether someone without known infertility will conceive naturally. The American Society for Reproductive Medicine advises against using ovarian reserve testing as a routine fertility screening tool for people who do not meet criteria for infertility.
If you're concerned about your fertility because of irregular cycles, a medical condition, your age, or your reproductive history, a healthcare professional can help determine whether testing would be useful and explain what the results actually mean.
Fertility Is Not Just About Women
When pregnancy does not happen as expected, it is important to remember that fertility involves both partners.
Sperm count, movement and other aspects of sperm health can affect the ability to conceive. Fertility evaluations may therefore include testing for both partners.
Knowing Your Body Is a Good Place to Start
You do not need to become an expert in fertility before trying to conceive.
Start by paying attention to your cycle, learning about ovulation and taking care of your general health. If something does not seem right, ask questions.
