Fertility myths – we’ve got the facts

negtestWe’ve heard of many different theories about fertility and becoming pregnant through AskUs. We’ve rounded up some of the ones we hear most often to help you weed through fact and fiction.

Q: Can folic acid help me get pregnant?

A: If you are trying to become pregnant, it is a good idea that you take a multivitamin that contains at least 400mcg of folic acid. This will help to prevent certain birth defects if you become pregnant. Folic acid, however, is not known to help with fertility in women. So, if you are having trouble becoming pregnant, folic acid is not something that will help you to conceive.

Q: I have an irregular period, can I get pregnant?

A: If you don’t have a regular period, there are other ways you can determine when you are ovulating, such as using your basal body temperature, cervical mucus and an ovulation prediction kit. For more tips, visit here.

Q: “Does drinking caffeine or smoking cigarettes affect my fertility?”

A: You may have heard that too much caffeine can cause miscarriage (when a baby dies in the womb before 20 weeks of pregnancy). Some studies say this is true, and others don’t. Until we know more about how caffeine can affect pregnancy, it’s best to limit the amount you get to 200 milligrams each day. This is about the amount in 1½ 8-ounce cups of coffee or one 12-ounce cup of coffee. Be sure to check the size of your cup to know how much caffeine you’re getting.

Smoking can affect your fertility and make it harder for you to get pregnant. Need help quitting? We’ve got resources.

Q: If I have sex a few days before ovulation will I conceive a girl?

A: Gender is determined at the moment of conception. During ovulation the ovaries release a mature egg that begins to travel to the uterus through the fallopian tubes. Sperm travel through the uterus to fertilize the egg within the fallopian tube. Only a single sperm fertilizes an egg. Both the sperm and the egg contain 23 chromosomes that will combine to make up the zygote which contains a total of 46 chromosomes. At conception, your baby’s gender, eye color, hair color, and much more has already been determined.

Of the 46 chromosomes that make up your baby’s genetic material, two chromosomes–one from your egg and one from your partner’s sperm–determine your baby’s gender. A woman’s egg contains only X sex chromosomes. A man’s sperm, however, may contain either an X or Y sex chromosome. If, at the instant of fertilization, a sperm with an X sex chromosome meets your egg (another X chromosome), your baby will be a girl (XX). If a sperm containing a Y sex chromosome meets your egg, your baby will be a boy (XY). It is always the father’s genetic contribution that determines the sex of the baby.

There are many old wives tales about choosing the sex of your baby but none of them have been proven.

Q: Will my birth control cause infertility?

A: The type of birth control you use may affect how soon you can get pregnant once you stop using it. To check your specific birth control, visit here.

Using birth control will not hurt your chances of becoming pregnant in the future. All reversible birth control methods will help prevent pregnancy while you’re using them, but they do not have long-lasting effects on your ability to get pregnant when you stop.
